    Nadine Jetten; Nadia Roumans; Marion J. Gijbels; Andrea Romano; Post, Mark J.; de Winther, Menno P.J.; Van der Hulst, Rene R. W. J.; Sofia Xanthoulea


    Macrophages play a crucial role in all stages of cutaneous wound healing responses and dysregulation of macrophage function can result in derailed wound repair. The phenotype of macrophages is influenced by the wound microenvironment and evolves during healing from a more pro-inflammatory (M1) profile in early stages, to a less inflammatory pro-healing (M2) phenotype in later stages of repair. The aim of the current study was to investigate the potential of exogenous administration of M2 macr...

    Macrophages play a crucial role in all stages of cutaneous wound healing responses and dysregulation of macrophage function can result in derailed wound repair. The phenotype of macrophages is influenced by the wound microenvironment and evolves during healing from a more pro-inflammatory (M1) profile in early stages, to a less inflammatory pro-healing (M2) phenotype in later stages of repair. The aim of the current study was to investigate the potential of exogenous administration of M2 macrophages to promote wound healing in an experimental mouse model of cutaneous injury. Bone marrow derived macrophages were stimulated in-vitro with IL-4 or IL-10 to obtain two different subsets of M2-polarized cells, M2a or M2c respectively. Polarized macrophages were injected into full-thickness excisional skin wounds of either C57BL/6 or diabetic db/db mice. Control groups were injected with non-polarized (M0) macrophages or saline. Our data indicate that despite M2 macrophages exhibit an anti-inflammatory phenotype in-vitro, they do not improve wound closure in wild type mice while they delay healing in diabetic mice. Examination of wounds on day 15 post-injury indicated delayed re-epithelialization and persistence of neutrophils in M2 macrophage treated diabetic wounds. Therefore, topical application of ex-vivo generated M2 macrophages is not beneficial and contraindicated for cell therapy of skin wounds.

  3. Characterization and release studies of liposomal gels containing glutathione/cyclodextrins complexes potentially useful for cutaneous administration. (United States)

    Cutrignelli, Annalisa; Lopedota, Angela; Denora, Nunzio; Laquintana, Valentino; Tongiani, Serena; Franco, Massimo


    The aim of this work is to develop and characterize a formulation intended for the cutaneous administration of glutathione (γ-glutamylcysteinylglycine, GSH), potentially useful for cellular defense against UV-induced damage. For this purpose, liposomes containing GSH or GSH/cyclodextrins(CDs) inclusion complexes as well as liposomes dispersed within a hydrophilic gel, were evaluated. These formulations were designed in order to obtain a system combining the advantages of liposomes as vehicles for topical drug delivery with those of CDs as penetration enhancers. The studied CDs were the natural (β-CD) and chemically modified (i.e., HP-β-CD and CH3 -β-CD) cyclodextrins. The prepared liposomes showed homogeneous size distribution, mean diameter in the range 622-1435 nm, small positive charge (+3.1 to +6.6 mV), and encapsulation efficiency of the peptide in the range 13.6%-23.7%. Release studies showed that the presence of the oligosaccharide may influence to some extent the amount of drug released, whereas stability studies clearly point out that the incorporation in a hydrophilic gel of 2-hydroxyethylcellulose insures a stable formulation maintaining unchanged the characteristics of liposomal vesicles.

  4. Local tetrahydrobiopterin administration augments reflex cutaneous vasodilation through nitric oxide-dependent mechanisms in aged human skin. (United States)

    Stanhewicz, Anna E; Bruning, Rebecca S; Smith, Caroline J; Kenney, W Larry; Holowatz, Lacy A


    Functional constitutive nitric oxide synthase (NOS) is required for full expression of reflex cutaneous vasodilation that is attenuated in aged skin. Both the essential cofactor tetrahydrobiopterin (BH(4)) and adequate substrate concentrations are necessary for the functional synthesis of nitric oxide (NO) through NOS, both of which are reduced in aged vasculature through increased oxidant stress and upregulated arginase, respectively. We hypothesized that acute local BH(4) administration or arginase inhibition would similarly augment reflex vasodilation in aged skin during passive whole body heat stress. Four intradermal microdialysis fibers were placed in the forearm skin of 11 young (22 ± 1 yr) and 11 older (73 ± 2 yr) men and women for local infusion of 1) lactated Ringer, 2) 10 mM BH(4), 3) 5 mM (S)-(2-boronoethyl)-l-cysteine + 5 mM N(ω)-hydroxy-nor-l-arginine to inhibit arginase, and 4) 20 mM N(G)-nitro-l-arginine methyl ester (l-NAME) to inhibit NOS. Red cell flux was measured at each site by laser-Doppler flowmetry (LDF) as reflex vasodilation was induced. After a 1.0°C rise in oral temperature (T(or)), mean body temperature was clamped and 20 mM l-NAME was perfused at each site. Cutaneous vascular conductance was calculated (CVC = LDF/mean arterial pressure) and expressed as a percentage of maximum (%CVC(max); 28 mM sodium nitroprusside and local heat, 43°C). Vasodilation was attenuated at the control site of the older subjects compared with young beginning at a 0.3°C rise in T(or). BH(4) and arginase inhibition both increased vasodilation in older (BH(4): 55 ± 5%; arginase-inhibited: 47 ± 5% vs. control: 37 ± 3%, both P 0.05) at a 1°C rise in T(or). With a 1°C rise in T(or), local BH(4) increased NO-dependent vasodilation in the older (BH(4): 31.8 ± 2.4%CVC(max) vs. control: 11.7 ± 2.0%CVC(max), P vasodilation in aged human skin and that BH(4) NOS coupling mechanisms may be a potential therapeutic target for increasing skin blood flow during

  5. Intradermal administration of ATP augments methacholine-induced cutaneous vasodilation but not sweating in young males and females. (United States)

    Fujii, Naoto; Halili, Lyra; Singh, Maya Sarah; Meade, Robert D; Kenny, Glen P


    Acetylcholine released from cholinergic nerves is a key neurotransmitter contributing to heat stress-induced cutaneous vasodilation and sweating. Given that sympathetic cholinergic nerves also release ATP, ATP may play an important role in modulating cholinergic cutaneous vasodilation and sweating. However, the pattern of response may differ between males and females given reports of sex-related differences in the peripheral mechanisms governing these heat loss responses. Cutaneous vascular conductance (CVC, laser-Doppler perfusion units/mean arterial pressure) and sweat rate (ventilated capsule) were evaluated in 17 young adults (8 males, 9 females) at four intradermal microdialysis skin sites continuously perfused with: 1) lactated Ringer (Control), 2) 0.3 mM ATP, 3) 3 mM ATP, or 4) 30 mM ATP. At all skin sites, methacholine was coadministered in a concentration-dependent manner (0.0125, 0.25, 5, 100, 2,000 mM, each for 25 min). In both males and females, CVC was elevated with the lone infusion of 30 mM ATP (both P 0.27). However, 0.3 mM ATP induced a greater increase in CVC compared with control in response to 100 mM methacholine infusion in males (P 0.44). We demonstrate that ATP enhances cholinergic cutaneous vasodilation albeit the pattern of response differs between males and females. Furthermore, we show that ATP does not modulate cholinergic sweating.

  6. Cutaneous zygomycosis. (United States)

    Bonifaz, Alexandro; Vázquez-González, Denisse; Tirado-Sánchez, Andrés; Ponce-Olivera, Rosa María


    Cutaneous zygomycosis is a fungal infection caused by zygomycetes that affects the skin. It occurs in uncontrolled diabetic patients and immunosuppressed individuals. It has 2 clinical forms: primary cutaneous zygomycosis and secondary cutaneous zygomycosis. The first is characterized by necrotic lesions and the fungus is usually inoculated by trauma. If diagnosed early, it generally has a good prognosis. Secondary zygomycosis is usually a complication and extension of the rhinocerebral variety that starts as a palpebral fistula and progresses to a necrotic lesion with a poor prognosis. The diagnosis is made by identification of the fungus by direct KOH examination, culture, and biopsy. Treatment for the primary disease is surgical debridement plus amphotericin B. The secondary type is treated with amphotericin B and/or posaconazole.

  7. Cutaneous sarcoidosis. (United States)

    Wilson, N J; King, C M


    Sarcoidosis is a multi-organ granulomatous disorder of unknown cause. Skin sarcoidosis occurs in about 25% of patients with systemic disease and may also arise in isolation. A wide range of clinical presentations of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy and the exclusion of other granulomatous skin disease. The treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement. In patients with aggressive disease limited to the skin immunosuppressive therapy may be indicated.

  9. Cutaneous leiomyosarcoma. (United States)

    Porter, Christopher J W; Januszkiewicz, Janek S


    Cutaneous leiomyosarcoma is a rare soft-tissue sarcoma with negligible metastatic potential, but local recurrence rates after surgical excision have ranged from 14 percent to 42 percent. Unlike other sarcomas, guidelines for the optimal surgical excision margin of cutaneous leiomyosarcoma are not clearly defined in the existing literature. A review of local experience with this condition revealed eight patients over 12 years, none of whom developed local recurrence or distant metastases. This is despite poor prognostic factors in seven patients and excision margins ranging from 1 to 27 mm. These findings are compared with previously published data, and conclusions are drawn based on analysis of the collective results. Complete surgical excision with a narrow margin is recommended, and patients should be observed for a minimum of 5 years after surgery.

  10. [Cutaneous leishmaniasis]. (United States)

    Enk, C D; Gardlo, K; Hochberg, M; Ingber, A; Ruzicka, T


    Leishmaniasis is a vector-borne disease caused by an obligate intracellular protozoa, Leishmania, which resides in macrophages. The parasite is transmitted by an infected female sandfly. The incidence of cutaneous leishmaniasis approaches 2 million new cases per year with 90% of the cases occurring in the "Old World", while the "New World" accounts for the rest. Infection may be restricted to the skin with development of characteristic ulcers, or may affect the mucous membranes in its mucocutaneous form. The clinical diagnosis is verified by the presence of amastigotes in slit-skin smears. Therapeutic modalities include systemic treatments such as the pentavalent antimony compound sodium stibogluconate, liposomal formulations of amphotericin B, oral ketoconazole or itraconazole, as well as topical paromomycin sulphate, local heat, freezing with liquid nitrogen, or photodynamic therapy. An effective vaccine is not available.

  11. Cutaneous mucormycosis. (United States)

    Skiada, Anna; Petrikkos, George


    Mucormycosis is an invasive fungal infection caused by fungi of the order Mucorales, mainly affecting immunocompromised patients. Cutaneous mucormycosis is the third most common clinical form of the disease, after pulmonary and rhino-cerebral. The usual factors predisposing to this infection are hematological malignancies and diabetes mellitus, but a significant proportion of patients are immunocompetent. The agents of mucormycosis are ubiquitous in nature and are transmitted to the skin by direct inoculation, as a result of various types of trauma. These include needle sticks, stings and bites by animals, motor vehicle accidents, natural disasters, and burn injuries. The typical presentation of mucormycosis is the necrotic eschar, but it can present with various other signs. The infection can be locally invasive and penetrate into the adjacent fat, muscle, fascia, and bone, or become disseminated. Diagnosis is difficult because of the nonspecific findings of mucormycosis. Biopsy and culture should be performed. The treatment of mucormycosis is multimodal and consists of surgical debridement, use of antifungal drugs (amphotericin B and posaconazole), and reversal of underlying risk factors, when possible. Mortality rates, although lower than in other forms of the disease, are significant, ranging from 4% to 10% when the infection is localized.

    Carvalho, Gustavo de Sá Menezes; Cavalcanti, Silvana Maria de Morais; Herênio, Alzinira Souza; Teixeira, Márcia Almeida Galvão; de Alencar, Eliane Ruth Barbosa; Gonçalves, Sergio Paulo Mendes


    We report a case of nevus lipomatosus cutaneous superficialis of Hoffman-Zurhelle (NCLS), with multiple lesions, in a ten-year-old child. The NLCS is considered rare. The classical clinical presentation is characterized by multiple skin-colored or yellowish papules and nodules, which can have a linear distribution. Histologically, it is characterized by the presence of mature ectopic adipocytes in the dermis. The main therapeutic option is surgical excision. The classical Nevus lipomatosus cutaneous superficialis is reported in this case.

  15. Cutaneous histiocytosis syndromes. (United States)

    Roper, S S; Spraker, M K


    Cutaneous histiocytosis may take two principal forms. It is either a benign proliferative process or a relentless, progressive process with a poor prognosis. In histiocytic medullary reticulosis, histiocytes demonstrate nuclear atypia and the outcome is uniformly fatal. Benign cephalic histiocytosis X causes lesions similar to those of histiocytosis X, but Langerhans' cells are absent. In congenital self-healing histiocytosis X, the Letterer-Siwe-like cutaneous infiltrate contains Langerhans' cells, but the lesions heal spontaneously without treatment. The nodular cutaneous lesions of juvenile xanthogranuloma appear in infancy and resolve without treatment; however, the higher percentage (10%) of associated ocular lesions may lead to glaucoma and blindness. In histiocytosis X, the cutaneous lesions show a marked proliferation of Langerhans' cells, with prognosis dependent on the patient's age and the extent of organ dysfunction. Patients who survive the acute form of the disease may develop diabetes insipidus, growth retardation, pulmonary fibrosis, and biliary cirrhosis. A subtle immunologic defect has been identified in patients with histiocytosis X, yet the pathogenesis of the disease is still speculative. Familial disease occurring in early infancy should be differentiated from complete or partial immunodeficiency syndromes. Guidelines for evaluating patients with cutaneous histiocytosis are reviewed.

  17. Cutaneous signs of piety. (United States)

    Ramesh, V; Al Aboud, Khalid


    It is important for dermatologists to be aware of cutaneous changes related to religious practices to help in their recognition and management. The anatomic location of cutaneous lesions associated with friction from praying varies based on religious practice. Allergic contact dermatitis from products and substances commonly used in worshipping also vary by religion. Some religious practices may render individuals prone to infections that manifest on the skin. Tattoos of godly figures also may adorn the body. Religious practices also have been implicated in cases of urticaria, köbnerization, and leukoderma. This article reviews the clinical presentation of some of the most common cutaneous changes that occur in individuals who practice the following religions: Christianity, Islam, Judaism, Hinduism, and Sikhism.

  18. Update on cutaneous calciphylaxis

    Directory of Open Access Journals (Sweden)

    Uwe Wollina


    Full Text Available Calciphylaxis is a devastating disorder with a mortality rate of 80% due to sepsis and organ failure. Hallmarks of this rare disease are arteriolar media calcification, thrombotic cutaneous ischemia, and necrotic ulcerations. Different mechanisms of vascular calcification can lead to calciphylaxis. Early diagnosis by deep cutaneous ulcer biopsy is most important for prognosis. Here, dermatologists play a significant role although treatment usually needs an interdisciplinary approach. Surgical procedures had been the cornerstone of treatment in the past including parathyroidectomy, but recently new medical treatments emerged aiming to normalize disturbances of minerals to reduce the serum concentration of sodium phosphate and to prevent precipitation and calcification. Multimodal therapy is warranted but only aggressive surgical debridement of cutaneous ulcers has shown significant outcome improvement.

    Mays, M B; Bergeron, J A


    Multifocal cutaneous histiocytic lesions were recognized in 9 dogs. Clinically, the dogs had multiple erythematous plaques or nodules in the skin (1 to 5 cm diameter). Histologically, the lesions were comprised of dermal or pannicular infiltrates of large histiocytic cells, with varying numbers of other inflammatory cells intermixed. By electron microscopy, the cells resembled those of canine cutaneous histiocytoma. The lesions seemed to wax and wane and appeared in new sites, regardless of treatment. The dogs ranged in age from 2 to 13 years; 7 dogs were under 6 years of age. Both sexes and various breeds were represented. An infectious agent could not be identified.

  6. Cutaneous xanthomas with concurrent demodicosis and dermatophytosis in a cat. (United States)

    Vogelnest, L J


    Multiple cutaneous xanthomas, associated with fasting hyperlipidaemia, are described in a 9-month-old domestic long-haired cat. A severely pruritic, papular, and crusting dermatitis affecting the head and neck, initially diagnosed as lesions of the eosinophilic granuloma complex, progressively developed on the head and pinnae. Pruritus was controlled with administration of prednisolone and chlorambucil. Repeat histological examination confirmed the diagnosis of cutaneous xanthoma and concurrent mild demodicosis. Marked fasting hypercholesterolaemia, hypertriglyceridaemia and transient hyperglycaemia were subsequently confirmed. Treatment for hyperlipidaemia and xanthomas with a low-fat diet (Hill's Feline r/d) and the previously unreported treatment for feline demodicosis of daily oral milbemycin were commenced. Multiple pink, alopecic plaques and papules gradually regressed, however pruritus recurred if immunosuppressive treatment was reduced, and well-demarcated areas of alopecia developed on the head, limbs and trunk, despite negative skin scrapings for demodex mites. Fungal culture of hair samples yielded Microsporum canis. All cutaneous lesions resolved with the addition of griseofulvin to the treatment regimen. Concurrent corneal ulceration and keratoconjunctivitis sicca ultimately resolved with treatment, including topical cyclosporin. Diabetes mellitus developed 6 months after resolution of skin lesions. No cutaneous or ocular abnormalities were present 6 months later with continued low-fat diet and insulin administration, although transient recurrence of papules and pruritus occurred after inadvertent access to a fatty meal. An underlying primary hyperlipidaemia was suspected, causing pruritic xanthomas. This may represent the first report of concurrent cutaneous xanthomas, demodicosis and dermatophytosis in a cat.

  7. Cutaneous mucormycosis postcosmetic surgery (United States)

    Al-Tarrah, Khaled; Abdelaty, Mahmoud; Behbahani, Ahmad; Mokaddas, Eman; Soliman, Helmy; Albader, Ahdi


    Abstract Background: Mucormycosis is a rare, aggressive, and life-threatening infection that is caused by organisms belonging to the order Mucorales. It is usually acquired through direct means and virtually always affects immunocompromised patients with the port of entry reflecting the site of infection, in this case, cutaneous. Unlike other mucormycoses, patients affected by Apophysomyces elegans (A elegans) are known to be immunocompetent. This locally aggressive disease penetrates through different tissue plains invading adjacent muscles, fascia, and even bone causing extensive morbidity and may prove fatal if treated inadequately. Cutaneous mucormycosis is associated with disruption of cutaneous barriers such as trauma. However, rarely, it may be iatrogenic. No cases have been previously reported postcosmetic surgery, especially one that is so commonly performed, lipofilling. Case Report: The patient is a, previously healthy, 41-year-old middle-eastern female who was admitted to the plastic surgery department 17 days after undergoing cosmetic surgery. She suffered from extensive tissue inflammation and necrosis in both gluteal regions. Following admission, she was initially started on empirical antimicrobial therapy which was changed to an antifungal agent, voriconazole, when preliminary microbiological results showed filamentous fungi. This was discontinued and liposomal amphotericin B was commenced when further mycological analysis identified A elegans. Furthermore, she underwent a total of 10 sessions of extensive debridement to the extent that portions of the sacrum and left femoral head became exposed. Her clinical status and wounds improved with the appropriate management and she remained an inpatient for 62 days. Subsequently, she had defects in both gluteal regions which required reconstructive surgery. Conclusion: A elegans is an uncommon cause of iatrogenic cutaneous mucormycosis. A high index of clinical suspicion is required, especially in the

    The adhesive cutaneous pharmaceutical forms aimed to local action release the drug substance in view of a dermatological, traumatological, antirheumatic, cosmetic action. Two such preparations were obtained and their stability, consistency and pH were determined. The "in vitro" tests of their bioavailability revealed the dynamics of calcium ions release according to the associations of each preparation. The bioavailability determined by evaluating the pharmacological response demonstrated the antiinflammatory action obtained by the association of calcium ions with the components extracted from poplar muds. The therapeutical efficiency of the studied preparations has proved in the treatment of some sport injuries.

  9. Chronic zosteriform cutaneous leishmaniasis

    Directory of Open Access Journals (Sweden)

    Omidian M


    Full Text Available Cutaneous leishmanasis (CL may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy.

  10. [Cutaneous histiocytosis X]. (United States)

    Metz, J; Metz, G; Lechner, W


    Histiocytosis X comprises three clinical entities whose common substrate is a localized or systemic proliferation of atypical histiocytes. On the basis of the age of manifestation, acuity of the clinical course and organ involvement Abt-Letterer-Siwe's disease, Hand-Schüller-Christian's disease and eosinophilic granuloma can be differentiated from each other, although transitional varieties of these syndromes are possible. Not infrequently oligosymptomatic forms are misinterpreted, especially when the skin is the only involved organ. In the following case report cutaneous histiocytosis X will be discussed in terms of its clinical expression. Electron-microscopy has proved to be the best methods to make the diagnosis of such atypical cases.

  11. Pure cutaneous histiocytosis X. (United States)

    Magaña-García, M


    A 38-month-old boy presented with nodules in the skin of the genital region present for 2 1/2 years. These later spread to the skin of the trunk, head, and extremities. A complete clinical workup could not reveal involvement in any other organ sites and biopsy of one of the cutaneous lesions was diagnosed as histiocytosis X. Because the child was in generally good condition, no treatment was given. Follow-up revealed that the disease had remained limited to the skin, where 15% of the lesions disappeared spontaneously.

  12. Cutaneous ulceration: an unusual complication of intravenous pentamidine therapy. (United States)

    Bolognia, J L


    Pentamidine is one of two agents currently used to treat infections with Pneumocystis carinii. The intramuscular route of administration is associated with cutaneous side effects such as dermal necrosis, sterile abscesses and ulcer formation at the injection site, while urticaria may develop near the site of intravenous drug infusion. This is a report of a renal transplant patient with Pneumocystis pneumonia who developed chemical cellulitis and ulceration following the extravasation of intravenous pentamidine into the soft tissues of the left hand and forearm. The area healed slowly over 7 weeks, but there was a residual loss of cutaneous sensation. In a review of the literature no report of a similar case was found.

  13. Cutaneous polyarteritis nodosa: A rare isolated cutaneous vasculitis

    Directory of Open Access Journals (Sweden)

    Praveen Kumar A Subbanna


    Full Text Available Cutaneous polyarteritis nodosa (CPAN is a rare form of cutaneous vasculitis that involves small and medium sized arteries of the dermis and subcutaneous tissue without systemic involvement. It presents with tender subcutaneous nodules, digital gangrene, livedo reticularis and subcutaneous ulcerations. The diagnosis is by skin biopsy and characteristic pathologic feature is a leukocytoclastic vasculitis in the small to medium-sized arterioles of the dermis. We report a rare case of benign cutaneous PAN in a 14-year-old girl who presented with history of fever, subcutaneous nodules with cutaneous ulcer and digital gangrene. The skin biopsy showed leukocytoclastic vasculitis with fibrinoid necrosis in the dermal vessels. She received treatment with steroids and lesions resolved completely over a period of month.

  14. Cutaneous Leishmaniasis with HIV. (United States)

    Talat, Humaira; Attarwala, Sharmeen; Saleem, Mubasshir


    Cutaneous Leishmaniasis (CL) is a vector borne disease caused by various species of the Leishmania parasite. CL is endemic in the province of Balochistan in Pakistan. In certain instances a Human Immunodeficiency Virus (HIV)-related immunocompromised is associated with atypical clinical presentation and occurrence of reactivated lesions of CL. Such presentations respond poorly to the standard treatment and frequent relapses are noted. We are reporting three cases of localized and disseminated CL due to Leishmania tropica which responded to meglumine antimoniate. Due to the fact that CL is endemic in Balochistan, we did not consider HIV infection as a causative organism. It was their presentation with history of weight loss and fever that prompted Enzyme-linked Immunosorbent Assay (ELISA) tests for HIV, which turned out to be positive. CL is becoming visible as an opportunistic infection associated with HIV/AIDS and may even be the first symptom in HIV positive patients in an endemic area.

  15. Cutaneous vasculitis: a review. (United States)

    As the skin is commonly involved in systemic vasculitic disorders as well as those hypersensitivity states whose expression is largely skin-confined, cutaneous vasculitic lesions offer a window to diagnosis and a ready source of accessible tissue for biopsy. In this review, we discuss the pathologic manifestations of chronic vasculitic syndromes such as granuloma faciale and erythema elevatum diutinum; IgA-associated vasculitis including Henoch-Schonlein purpura; vasculitis seen in the setting of cryoglobulinemia and hypergammaglobulinemia of Waldenstrom, hereditary deficiencies of complement, and IgA deficiency; those leukocytoclastic vasculitides resulting from hypersensitivity reactions to drug, chemical and foodstuff ingestion; and those vasculitides seen in patients with systemic diseases such as polyarteritis nodosa, rheumatoid arthritis, mixed connective tissue disease, systemic lupus erythematosus, Sjogren's syndrome, relapsing polychondritis, Behcet's disease, Wegener's granulomatosis, and allergic granulomatosis of Churg and Strauss.

    Radiotherapy plays an important role in the treatment of cutaneous lymphomas. In the treatment of Mycosis fungoides, total skin electron beam radiation therapy is efficient for patients with limited and superficial forms of the disease. Radiotherapy is also efficient for the locally advanced forms of non-epidermo-tropic lymphomas. The palliative radiotherapy is indicated for advanced, nodular and treatment resistant forms of cutaneous lymphomas and for voluminous lymphadenopathies. (authors)

  17. Clinical Observation on Comprehensive Treatment on Cutaneous Region for Low Back Pain

    Institute of Scientific and Technical Information of China (English)

    Zhao Feng; Liu Shu-tian


    Objective: To observe the clinical effects of comprehensive treatmenton cutaneous region for low back pain. Methods: One hundred and twenty outpatients with low back pain who met the diagnostic criteria were randomly divided into a cutaneous region group or a medication group, 60 cases in each group. The cases in the cutaneous region group were treated by Nie-pinching up the skin of the lumbosacral region, cupping and acupuncture. Those in the medication group were treated by oral administration of Celecoxib capsule. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess the therapeutic effects. Results: After treatment, the VAS scores of both groups were different from those before treatment, showing statistical significances (allP Conclusion: Both comprehensive treatment on the cutaneous region and Celecoxib capsule can obviously relieve low back pain. But comprehensive treatment on the cutaneous region is better than Celecoxib capsule in the therapeutic effects.

  20. Systemic diseases with cutaneous manifestations. (United States)

    Merchant, S R; Taboada, J


    The purpose of this article is to briefly discuss the following cutaneous manifestations of selected systemic diseases: poxvirus; feline leukemia virus (FeLV); feline immunodeficiency virus (FIV); herpesvirus; calcivirus; pseudorabies; plague; tularemia; toxoplasmosis; leishmania; hypothyroidism; hyperthyroidism; hyperadrenocorticism; diabetes mellitus; acromegaly; thallium poisoning; pancreatic disease; hypereosinophilic syndrome; mucopolysaccharidosis; and pansteatitis. Recognition of these cutaneous signs may help alert the clinician to the possibility of an internal disorder so that the appropriate diagnostic tests can be considered.

  1. Cutaneous actinomycosis: A rare case

    Directory of Open Access Journals (Sweden)

    Metgud S


    Full Text Available Cutaneous actinomycosis is a rare presentation. Here we present a case of cutaneous actinomycosis with no history of trauma or systemic dissemination. The isolate was identified as Actinomyces viscosus by standard methods. The isolate was found to be penicillin resistant by Kirby Bauer disc diffusion method. Therefore, the patient was treated with cotrimoxazole and improved. Thus, this case highlights the importance of isolation and susceptibility testing in actinomycotic infection. The sinuses have healed, and the patient has recovered.

  2. Genotyping of cutaneous melanoma. (United States)

    Glitza, Isabella C; Davies, Michael A


    Until recently, treatment options for patients with metastatic melanoma were very limited. This landscape has evolved dramatically since the discovery of activating mutations in the BRAF gene in ~45% of cutaneous melanomas. Vemurafenib, dabrafenib, and trametinib have all received regulatory approval for the treatment of metastatic melanoma patients with a BRAF(V600) mutation. Based on the necessity to document the presence of a BRAF(V600) mutation to prescribe these agents, molecular testing is now the standard of care in this disease. However, the options and rationale for testing are evolving rapidly due to an improved understanding of the molecular drivers and heterogeneity of melanoma. Such testing may identify rational combinatorial approaches to prevent or overcome resistance for the approved BRAF inhibitors. In addition, new clinical strategies have been identified for a number of other molecular changes that are detected in this disease, including somatic changes in NRAS, PTEN, CDKN2A, and c-KIT, among others. This review summarizes the current understanding of the genetic landscape of mutations in melanoma, their associations with clinicopathological features, and their implications for clinical testing and treatment.

  3. Aspects of cutaneous ageing. (United States)

    Dalziel, K L


    'Ageing is a multistep, multifaceted, time-dependent phenomenon characterized by the decreased ability of a system to respond to exogenous and endogenous stress from either physical, chemical or biologic agents'. Cutaneous ageing provides a visible model of the interaction between endogenous (intrinsic) factors and exogenous (extrinsic) factors. In skin, the principal extrinsic-factor is ultraviolet light (UV) which is responsible for the constellation of changes termed photoageing. In recent years, much interest has been directed towards defining the ageing processes in skin and excellent comprehensive reviews have been compiled. This review aims to highlight several areas of developing knowledge, and focuses on the potential importance of environmental changes as they influence skin ageing and carcinogenesis. Repeated reference to the effects of UV on the skin are inevitable in any review of skin ageing and this is scarcely surprising as the skin contains many cells as well as subcellular and extracellular chromophores which are capable of absorbing energy within the UV spectrum. Cellular chromophores include among others keratinocytes, melanocytes, Langerhans cells, dermal fibroblasts and mast cells. Subcellular chromophores include keratin, melanin, collagen, elastin and a number of proteins, lipids and steroids (such as vitamin D). Urocanic acid, a photoisomerization product of the amino-acid histidine, may provide some limited photoprotection and some believe it to be important in UV induced immunosuppression. Understanding events at the molecular and biochemical level has unfortunately not been paralleled by clinical advances and the common, troublesome skin-problems of old age such as cancer, xerosis and pruritus remain a major cause of morbidity and yet are poorly explained.

  4. "Pure" cutaneous histiocytosis-X. (United States)

    Wolfson, S L; Botero, F; Hurwitz, S; Pearson, H A


    The case histories of two young children who experienced skin rashes involving various areas of the body are reported. The diagnosis of pure cutaneous histiocytosis-X was established after extensive studies revealed no other organ involvement. The patients were treated with oral corticosteroids. Currently, both children are in good health, show no evidence of disease, and have been followed over a four-to-five-year period. Therapy with corticosteroids may not be indicated with pure cutaneous histiocytosis-X unless there is evidence of extracutaneous dissemination or rapid progression of the disease.

  5. Cutaneous foetal injuries related to amniocentesis. (United States)

    Papi, L; Farusi, F; Teti, G; Dini, V; Romanelli, M


    Amniocentesis is one of the most important prenatal diagnostic procedures available to assess congenital abnormalities. It is performed worldwide due to its simplicity of execution and lack of risk. The most frequent known accidents in amniocentesis are abortion, oligohydramnios, amniositis and placental abruption, while direct fetal injuries produced by contact with the needle are rarely seen. The injuries produced are extremely variable in severity, but the most frequent is skin wounds, which usually heal as small, round depressed scars. The cases we describe concern the occurrence of iatrogenic cutaneous wound lesions to a fetus during amniocentesis. The medical-legal analysis of the cases required dermatological expertise in order to exclude a different pathogenesis for the skin injuries to the child and were assigned by the court, in order to assess the administrative compensation due to the parents of the child as a result of medical malpractice.

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

  11. Parasitic Diseases With Cutaneous Manifestations. (United States)

    Ash, Mark M; Phillips, Charles M


    Parasitic diseases result in a significant global health burden. While often thought to be isolated to returning travelers, parasitic diseases can also be acquired locally in the United States. Therefore, clinicians must be aware of the cutaneous manifestations of parasitic diseases to allow for prompt recognition, effective management, and subsequent mitigation of complications. This commentary also reviews pharmacologic treatment options for several common diseases.

  15. Molecular genetics of cutaneous lymphomas. (United States)

    Whittaker, S


    The underlying molecular basis of primary cutaneous lymphomas has not yet been clarified. However, abnormalities of cell cycle control genes and well-defined tumor suppressor genes such as p53 are common and may contribute to disease progression and treatment resistance. Biallelic inactivation of tumor suppressor genes usually occurs by a combination of deletion, point mutation, and/or promotor hypermethylation. The detection of UVB-specific mutations of p53 requires confirmation but may have important implications for the management of patients with mycosis fungoides. Molecular cytogenetic studies have identified common regions of chromosomal deletion and amplification, which suggests the presence and location of genes that are of critical importance in the pathogenesis of cutaneous lymphoma.

  16. Cutaneous myiasis from Dermatobia hominis. (United States)

    Guse, S T; Tieszen, M E


    We present a case report of cutaneous myiasis in a foreign traveler who was infected by Dermatobia hominis while visiting South America. This patient developed a painful furuncular lesion on the anterior scalp and noted that the lesion drained a serosanguinous fluid for more than a month before definitive treatment. Invasion of mammalian tissue by the larval forms of D. hominis typically results in the formation of a classic furuncular lesion. For persons who present with a lesion that contains a central draining stoma located on an exposed body surface, the diagnosis of myiasis should always be considered. In addition to the case report, we present a discussion of furuncular myiasis and describe the peculiar life cycle of the human botfly. We also describe the various therapies that may be employed for treating cutaneous myiasis, including surgical extraction of the larva and asphyxiation of the larva by application of petroleum jelly or other fat derivatives to the central stoma or breathing aperture.

  17. Multiple isolated cutaneous plexiform schwannomas

    Directory of Open Access Journals (Sweden)

    Enas A. S. Attia


    Full Text Available Plexiform schwannoma is a rare neurogenic tumor, arising from skin and subcutaneous tissue. The presence of multiple schwannomas suggests a possible association with neurofibromatosis type 2 (NF2. A 50-year old male patient presented with multiple papulo-nodular cutaneous lesions on both arms and forearms. Histopathological examination revealed a dermal multinodular pattern of well-circumscribed masses of closely packed cells, with peripheral myxoid tissue, well-encapsulated in a thin collagenous capsule. S-100 immunohistochemical staining was diffusely and strongly positive. Neuron-specific enolase was positive, confirming a neural tissue tumor. An audiogram and Magnetic Resonance Imaging (MRI of cerebro-pontine angle showed no detected abnormality, excluding acoustic neuroma. Thus, we present a case of multiple bilateral isolated cutaneous plexiform schwannomas, not associated with NF2. Multiple plexiform schwannomas is a very rare entity, distinct from neurofibromatosis (NF, and being confined to the dermis is even more rarely reported.

  18. Cutaneous manifestations of human toxocariasis. (United States)

    Gavignet, Béatrice; Piarroux, Renaud; Aubin, François; Millon, Laurence; Humbert, Philippe


    Human toxocariasis is a parasitic disease characterized by the presence of larvae of the genus Toxocara in human tissues. T canis and T cati, the adult roundworms of which are found in dog and cat intestines, respectively, are the most common causative agents of the disease. Toxocaral larvae usually cause two severe syndromes: visceral larva migrans and ocular larva migrans, depending on the location of the larvae. Two other syndromes, covert toxocariasis and common toxocariasis, which are less typical and not as severe, have also been described. During the last two decades, cutaneous manifestations such as chronic urticaria, chronic pruritus, and miscellaneous eczema, in patients with Toxocara antibodies, have been studied by different authors. In some cases, these cutaneous manifestations are the only signs indicating the presence of the disease, and they are cured after antihelmintic treatment when there is good patient compliance. In this review, we focus on these particular skin manifestations regarding their clinical description, diagnosis, and treatment.

  19. Cutaneous manifestations of viral hepatitis. (United States)

    Akhter, Ahmed; Said, Adnan


    There are several extrahepatic cutaneous manifestations associated with hepatitis B and hepatitis C virus infection. Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection. The clinico-pathogenic associations of these skin conditions are not completely defined but appear to involve activation of the host immune system including the complement system. Management of the aforementioned cutaneous manifestations of viral hepatitis is often similar to that done in cases without viral hepatitis, with control of immune activation being a key strategy. In cases associated with hepatitis B and C, control of viral replication with specific antiviral therapy is also important and associated with improvement in most of the associated clinical manifestations.

The possible causative mechanisms are discussed when they are applicable and the outline of their management is described.

  1. Cutaneous polyarteritis nodosa: an update. (United States)

    Furukawa, Fukumi


    Cutaneous symptoms are observed in 25%-60% of polyarteritis nodosa (PN) patients. On the other hand, cutaneous polyarteritis nodosa (CPN) is designated for the cutaneous limited form of PN and demonstrates benign prognosis. However, there has been much debate on whether or not CPN can progress to PN. Although CPN lesions are fundamentally limited to skin, some CPN cases show extracutaneous symptoms such as peripheral neuropathy and myalgia. According to PN diagnostic criteria, a disease with both cutaneous and at least one extracutaneous symptom with appropriate histopathological findings can be diagnosed as PN. The same is true according to diagnostic criteria established by American College of Rheumatology (ACR). In addition, there are no specific diagnostic criteria for CPN. In this study, CPN cases were retrospectively collected from multiple Japanese clinics, and analyzed for detailed clinical and histopathological manifestations, in order to redefine the clinical entity of CPN and to propose appropriate diagnostic criteria for CPN and PN. According to the CPN description in Rook's Textbook of Dermatology, one of global standard textbooks, we collected 22 cases with appropriate histopathological findings. Of the 22 cases, none progressed to PN or death during the follow-up period, 32% had peripheral neuropathy, and 27% had myalgia. Regarding extracutaneous symptoms with CPN, 17 dermatological specialists in vasculitis sustained the opinion that CPN can be accompanied by peripheral neuropathy and myalgia, but these symptoms are limited to the same area as skin lesions. Based on these results, we devised new drafts for CPN and PN diagnostic criteria. Our study shows the efficacy of these criteria, and most dermatologists recognized that our new diagnostic criteria for CPN and PN are appropriate at the present time. In conclusion, this study suggests that CPN does not progress to PN, and introduces new drafts for CPN and PN diagnostic criteria. (*English

  2. Newly recognized cutaneous drug eruptions. (United States)

    Many new drugs are entering the marketplace and although some cutaneous reactions might be noted in the preclinical evaluation, some of the reactions, particularly those that are rare, will not be noted until the drugs enter widespread use. In addition, distinctive reactions may occur, as is the case with epidermal growth factor-receptor inhibitors. Careful observation and evaluation might result in a better understanding of "naturally" occurring skin disease.

    Full Text Available Background: Many malignancies affecting the internal organs display cutaneous manifestations which may be either specific (tumor metastases or nonspecific lesions. Aims: The study is aimed at determining the frequency and significance of cutaneous manifestations among patients with internal malignancy. Materials and Methods: 750 cases of proven internal malignancy, who attended a cancer chemotherapy center in South India, were studied. Specific infiltrates were confirmed by histopathology, fine needle aspiration cytology (FNAC and marker studies. Results: Out of the 750 patients with internal malignancy, skin changes were seen in a total of 52 (6.93% patients. Conclusion: Cutaneous metastases (specific lesions were seen in 20 patients (2.66%: contiguous in 6 (0.8%, and non-contiguous in 14 (1.86%. Nonspecific skin changes were seen in 32 patients (4.26%. None of our patients presented with more than one type of skin lesions. Herpes zoster was the most common nonspecific lesion noticed in our patients, followed by generalized pruritus, multiple eruptive seborrheic keratoses, bullous disorder, erythroderma, flushing, purpura, pyoderma gangrenosum, insect bite allergy and lichenoid dermatitis.

  6. Cutaneous Chromatophoromas in Captive Snakes. (United States)

    Muñoz-Gutiérrez, J F; Garner, M M; Kiupel, M


    Chromatophoromas are neoplasms arising from pigment-bearing cells (chromatophores) of the dermis. While isolated cases have been reported in the literature, the prevalence and biological behavior of chromatophoromas in snakes are unknown. Forty-two chromatophoromas were identified among 4663 submissions (0.9%) to a private diagnostic laboratory in a 16-year period. The most commonly affected snakes were colubrids (23 cases, 55%) and vipers (8 cases, 19%). The San Francisco garter snake was the most commonly affected species (6 cases; 14% of all affected snake species and 3.7% of all garter snake submissions). No sex predilection was found. The age of 28 snakes ranged from 5 to 27 years. Single cutaneous chromatophoromas were most commonly observed and presented as pigmented cutaneous masses or plaques along any body segment. Euthanasia or death due to progressive neoplastic disease or metastasis was reported in 8 (19%) and 4 (10%) cases, respectively. The survival time of 4 animals ranged from 4 to 36 months. Microscopically, xanthophoromas, iridophoromas, melanocytic neoplasms, and mixed chromatophoromas were identified, with melanocytic neoplasms being most common. Microscopic examination alone was generally sufficient for the diagnosis of chromatophoroma, but immunohistochemistry for S-100 and PNL-2 may be helpful for diagnosing poorly pigmented cases. Moderate to marked nuclear atypia appears to be consistently present in cutaneous chromatophoromas with a high risk of metastasis, while mitotic count, lymphatic invasion, the level of infiltration, and the degree of pigmentation or ulceration were not reliable predictors of metastasis.

  7. [Cutaneous adverse effects of TNFalpha antagonists]. (United States)

    Failla, V; Sabatiello, M; Lebas, E; de Schaetzen, V; Dezfoulian, B; Nikkels, A F


    The TNFalpha antagonists, including adalimumab, etanercept and infliximab, represent a class of anti-inflammatory and immunosuppressive drugs. Although cutaneous adverse effects are uncommon, they are varied. There is no particular risk profile to develop cutaneous adverse effects. The principal acute side effects are injection site reactions and pruritus. The major long term cutaneous side effects are infectious and inflammatory conditions. Neoplastic skin diseases are exceptional. The association with other immunosuppressive agents can increase the risk of developing cutaneous adverse effects. Some adverse effects, such as lupus erythematosus, require immediate withdrawal of the biological treatment, while in other cases temporary withdrawal is sufficient. The majority of the other cutaneous adverse effects can be dealt without interrupting biologic treatment. Preclinical and clinical investigations revealed that the new biologics, aiming IL12/23, IL23 and IL17, present a similar profile of cutaneous adverse effects, although inflammatory skin reactions may be less often encountered compared to TNFalpha antagonists.

    Full Text Available Inflammatory bowel disease (IBD has many extraintestinal manifestations, and skin lesions are one of the most frequently described extraintestinal findings. Reports indicate an incidence of cutaneous manifestations ranging from 2 to 34%, Cutaneous manifestations are usually related to the activity of the bowel disease but may have an independent course. In this review we aim to address the various cutaneous manifestations associated with IBD, their impact on the disease course, and the treatment options available.

  9. Ethosomes and organogels for cutaneous administration of crocin. (United States)

    Esposito, Elisabetta; Drechsler, Markus; Huang, Nicolas; Pavoni, Gabriella; Cortesi, Rita; Santonocito, Debora; Puglia, Carmelo


    The present study describes the production and characterization of phosphatidylcholine based ethosomes and organogels, as percutaneous delivery systems for crocin. Crocin presence did not influence ethosome morphology, while the drug slightly increased ethosome mean diameter. Importantly, the poor chemical stability of crocin has been found to be long controlled by organogel. To investigate the performance of phosphatidylcholine lipid formulations as crocin delivery system, in vivo studies, based on tape stripping and skin reflectance spectrophotometry, were performed. Tape stripping results suggested a rapid initial penetration of crocin exerted by the organogel, probably due to a strong interaction between the peculiar supramolecular aggregation structure of phospholipids in the vehicle and the lipids present in the stratum corneum and a higher maintenance of crocin concentration in the case of ethosomes, possibly because of the formation of a crocin depot in the stratum corneum. Skin reflectance spectrophotometry data indicated that both vehicles promoted the penetration of crocin through the skin, with a more rapid anti-inflammatory effect exploited by ethosomes, attributed to an ethanol pronounced penetration enhancer effect and to the carrier system as a whole.

  10. Cutaneous histoplasmosis in renal transplant recipients. (United States)

    Sun, N Z; Augustine, J J; Gerstenblith, M R


    Cutaneous histoplasmosis is a rare entity, although it can be seen in a substantial portion of renal transplant recipients with disseminated disease. The prognosis of disseminated disease is worse than isolated cutaneous involvement, and significant delays in diagnosis are reported. We reviewed reports of cutaneous histoplasmosis with and without dissemination in the setting of renal transplantation to examine incidence, timing of diagnosis, clinical features, and prognosis. Remarkable morphologic variability and the non-specific appearance of skin findings suggest that tissue culture is required for definitive diagnosis. Cutaneous lesions represent an easily accessible source for early diagnosis.

  11. Cutaneous dermatomyositis in the era of biologicals. (United States)

    Wright, Natalie A; Vleugels, Ruth Ann; Callen, Jeffrey P


    Dermatomyositis (DM) is a systemic inflammatory condition characterized by cutaneous and muscle findings, in addition to potential involvement of other organ systems. A distinct subtype of DM exists that is categorized by cutaneous findings with absent or minimal muscle involvement, referred to as clinically amyopathic dermatomyositis or dermatomyositis sine myositis. A variety of topical, immunosuppressive, and immunomodulatory therapies have been utilized to treat cutaneous DM. The advent of biological agents including tumor necrosis factor-α antagonists, intravenous immunoglobulin, rituximab, and others has allowed for the use of these agents with varying degrees of success for the treatment of cutaneous DM.

  12. Cubic Phases, Cubosomes and Ethosomes for Cutaneous Application. (United States)

    Esposito, Elisabetta; Drechsler, Markus; Nastruzzi, Claudio; Cortesi, Rita


    Cutaneous administration represents a good strategy to treat skin diseases, avoiding side effects related to systemic administration. Apart from conventional therapy, based on the use of semi-solid formulation such as gel, ointments and creams, recently the use of specialized delivery systems based on lipid has been taken hold. This review provides an overview about the use of cubic phases, cubosomes and ethosomes, as lipid systems recently proposed to treat skin pathologies. In addition in the final part of the review cubic phases, cubosomes and ethosomes are compared to solid lipid nanoparticles and lecithin organogel with respect to their potential as delivery systems for cutaneous application. It has been reported that lipid nanosystems are able to dissolve and deliver active molecules in a controlled fashion, thereby improving their bioavailability and reducing side-effects. Particularly lipid matrixes are characterized by skin affinity and biocompatibility allowing their application on skin. Indeed, after cutaneous administration, the lipid matrix of cubic phases and cubosomes coalesces with the lipids of the stratum comeum and leads to the formation of a lipid depot from which the drug associated to the nanosystem can be released in the deeper skin strata in a controlled manner. Ethosomes are characterized by a malleable structure that promotes their interaction with skin, improving their potential as skin delivery systems with respect to liposomes. Also in the case of solid lipid nanoparticles it has been suggested a deep interaction between lipid matrix and skin strata that endorses sustained and prolonged drug release. Concerning lecithin organogel, the peculiar structure of this system, where lecithin exerts a penetration enhancer role, allows a deep interaction with skin strata, promoting the transdermal absorption of the encapsulated drugs.

    Bari Arfan Ul


    Full Text Available Background: Cutaneous leishmaniasis (CL is known for its clinical diversity and increasing numbers of new and rare variants of the disease are being reported these days. Aim: The aim of this descriptive study was to look for and report the atypical presentations of this common disease occurring in Pakistan. Methods: The study was carried out in three hospitals (MH, Rawalpindi; PAF Hospital, Sargodha; and CMH, Muzaffarabad from 2002 to 2006. Military and civilian patients of all ages, both males and females, belonging to central and north Punjab province and Kashmir were included in the study. Clinical as well as parasitological features of cutaneous leishmaniasis were studied. The unusual lesions were photographed and categorized accordingly using simple descriptive statistics. Results: Out of 718 patients of cutaneous leishmaniasis, 41 (5.7% had unusual presentations. The commonest among unusual morphologies was lupoid leishmaniasis 14 (34.1%, followed by sporotrichoid 5 (12.1%, paronychial 3 (7.3%, lid leishmaniasis 2 (4.9%, psoriasiform 2 (4.9%, mycetoma-like 2 (4.9%, erysipeloid 2 (4.9%, chancriform 2 (4.9%, whitlow 1 (2.4%, scar leishmaniasis 1 (2.4%, DLE-like 1 (2.4%, ′squamous cell carcinoma′-like 1 (2.4%, zosteriform 1 (2.4%, eczematous 1 (2.4%, verrucous 1 (2.4%, palmar/plantar 1 (2.4% and mucocutaneous 1 (2.4%. Conclusion: In Pakistan, an endemic country for CL, the possibility of CL should be kept in mind while diagnosing common dermatological diseases like erysipelas, chronic eczema, herpes zoster, paronychia; and uncommon disorders like lupus vulgaris, squamous cell carcinoma, sporotrichosis, mycetoma and other deep mycoses.

  15. Cutaneous manifestations of chikungunya fever. (United States)

    Seetharam, K A; Sridevi, K; Vidyasagar, P


    Chikungunya fever, a re-emerging RNA viral infection produces different cutaneous manifestations in children compared to adults. 52 children with chikungunya fever, confirmed by positive IgM antibody test were seen during 2009-2010. Pigmentary lesions were common (27/52) followed by vesiculobullous lesions (16/52) and maculopapular lesions (14/52). Vesiculobullous lesions were most common in infants, although rarely reported in adults. Psoriasis was exacerbated in 4 children resulting in more severe forms. In 2 children, guttate psoriasis was observed for the first time.

  16. Targeted therapies for cutaneous melanoma. (United States)

    Kee, Damien; McArthur, Grant


    Melanoma is resistant to cytotoxic therapy, and treatment options for advanced disease have been limited historically. However, improved understanding of melanoma driver mutations, particularly those involving the mitogen-activated protein kinase pathway, has led to the development of targeted therapies that are effective in this previously treatment-refractory disease. In cutaneous melanomas with BRAF V600 mutations the selective RAF inhibitors, vemurafenib and dabrafenib, and the MEK inhibitor, trametinib, have demonstrated survival benefits. Early signals of efficacy have also been demonstrated with MEK inhibitors in melanomas with NRAS mutations, and KIT inhibitors offer promise in melanomas driven through activation of their target receptor.

    Full Text Available "nThis case report states a 25-year-old woman, residing in the city of Dezfool, Khuzestan Province, south of Iran with the diagnosis of cutaneous leishmaniasis in June 2008. Her skin lesion had de­veloped from 8 months earlier as a nodule on her left arm, 1×3 cm in diameter. Because of sever­ity of the lesion, we prescribed meglumine antimoniate intralesionally with giving up her breast feeding. After 6 months follow-up, no recurrence was seen.

  18. Mechanics of cutaneous wound rupture. (United States)

    Swain, Digendranath; Gupta, Anurag


    A cutaneous wound may rupture during healing as a result of stretching in the skin and incompatibility at the wound-skin interface, among other factors. By treating both wound and skin as hyperelastic membranes, and using a biomechanical framework of interfacial growth, we study rupturing as a problem of cavitation in nonlinear elastic materials. We obtain analytical solutions for deformation and residual stress field in the skin-wound configuration while emphasizing the coupling between wound rupture and wrinkling in the skin. The solutions are analyzed in detail for variations in stretching environment, healing condition, and membrane stiffness.

  19. Drug-induced subacute cutaneous lupus erythematosus. (United States)

    Callen, J P


    Subacute cutaneous lupus erythematosus (SCLE) is a subset of cutaneous lupus erythematosus with unique immunologic and clinical features. The first description dates back to 1985 when a series of five patients were found to have hydrochlorothiazide-induced SCLE. Since that time, at least 40 other drugs have been implicated in the induction of SCLE.

  20. Cutaneous fistulization of the hydatid disease (United States)

    Bahce, Zeynep Sener; Akbulut, Sami; Aday, Ulas; Demircan, Firat; Senol, Ayhan


    Abstract Aim: To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD). Methods: According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst. Results: The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7–93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations. Conclusion: Cutaneous fistulization is a rare complication of HD

  1. Selenium for the Prevention of Cutaneous Melanoma

    Directory of Open Access Journals (Sweden)

    Douglas Grossman


    Full Text Available The role of selenium (Se supplementation in cancer prevention is controversial; effects often depend on the nutritional status of the subject and on the chemical form in which Se is provided. We used a combination of in vitro and in vivo models to study two unique therapeutic windows for intervention in the process of cutaneous melanomagenisis, and to examine the utility of two different chemical forms of Se for prevention and treatment of melanoma. We studied the effects of Se in vitro on UV-induced oxidative stress in melanocytes, and on apoptosis and cell cycle progression in melanoma cells. In vivo, we used the HGF transgenic mouse model of UV-induced melanoma to demonstrate that topical treatment with l-selenomethionine results in a significant delay in the time required for UV-induced melanoma development, but also increases the rate of growth of those tumors once they appear. In a second mouse model, we found that oral administration of high dose methylseleninic acid significantly decreases the size of human melanoma xenografts. Our findings suggest that modestly elevation of selenium levels in the skin might risk acceleration of growth of incipient tumors. Additionally, certain Se compounds administered at very high doses could have utility for the treatment of fully-malignant tumors or prevention of recurrence.

  2. Acceleration of cutaneous wound healing by brassinosteroids. (United States)

    Esposito, Debora; Rathinasabapathy, Thirumurugan; Schmidt, Barbara; Shakarjian, Michael P; Komarnytsky, Slavko; Raskin, Ilya


    Brassinosteroids are plant growth hormones involved in cell growth, division, and differentiation. Their effects in animals are largely unknown, although recent studies showed that the anabolic properties of brassinosteroids are possibly mediated through the phosphoinositide 3-kinase/protein kinase B signaling pathway. Here, we examined biological activity of homobrassinolide (HB) and its synthetic analogues in in vitro proliferation and migration assays in murine fibroblast and primary keratinocyte cell culture. HB stimulated fibroblast proliferation and migration and weakly induced keratinocyte proliferation in vitro. The effects of topical HB administration on progression of wound closure were further tested in the mouse model of cutaneous wound healing. C57BL/6J mice were given a full-thickness dermal wound, and the rate of wound closure was assessed daily for 10 days, with adenosine receptor agonist CGS-21680 as a positive control. Topical application of brassinosteroid significantly reduced wound size and accelerated wound healing in treated animals. mRNA levels of transforming growth factor beta and intercellular adhesion molecule 1 were significantly lower, while tumor necrosis factor alpha was nearly suppressed in the wounds from treated mice. Our data suggest that topical application of brassinosteroids accelerates wound healing by positively modulating inflammatory and reepithelialization phases of the wound repair process, in part by enhancing Akt signaling in the skin at the edges of the wound and enhancing migration of fibroblasts in the wounded area. Targeting this signaling pathway with brassinosteroids may represent a promising approach to the therapy of delayed wound healing.

  3. Cutaneous sporotrichosis: Unusual clinical presentations

    Directory of Open Access Journals (Sweden)

    Mahajan Vikram


    Full Text Available Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/ available.

  4. Cutaneous signs of classical dermatomyositis. (United States)

    Auriemma, M; Capo, A; Meogrossi, G; Amerio, P


    Idiopathic immune myopathies (IIM) are an heterogeneous group of autoimmune muscle disorders characterized by progressive muscle involvement. Dermatomyositis (DM) is the most common form of IIM. It is a multisystem disorder characterized by symmetric proximal, extensor, inflammatory myopathy, vascular involvement and a characteristic cutaneous eruption. Six types of DM have been identified: idiopathic, juvenile (JDM), cancer-related other autoimmune diseases-related, iatrogenic DM and amyopathic DM. Cutaneous manifestations of DM are the most important aspect of this disease and can precede from several months to years muscle or systemic involvement. Three groups of signs have been described: pathognomonic, highly characteristic and compatible. Although differences exist among the different clinical presentation of skin lesions, they share common histological findings including the presence of interface dermatitis with epidermal atrophy, basement membrane degeneration, vacuolar alteration of basal keratinocytes, and dermal changes consisting of interstitial mucin deposition and a sparse lymphocytic infiltrate. DM is a serious disease; the correct evaluation of any skin lesion suggesting an early diagnosis is of utmost importance. Skin signs may, also, represent a marker of treatment efficacy even though systemic symptoms worsening may not always be followed by more severe skin lesions.

  5. Drug-induced cutaneous vasculitides. (United States)

    Antiga, E; Verdelli, A; Bonciani, D; Bonciolini, V; Quintarelli, L; Volpi, W; Fabbri, P; Caproni, M


    Cutaneous vasculitides (CV) can be idiopathic or secondary to several triggers, including drugs, which account for up to 30% of all the cases of CV. Several drugs can induce CV, including some medications commonly used in dermatology, including minocycline, and several new drugs, such as anti-TNF agents. Different pathomecanisms are involved in the development of drug-induced CV, including the formation and deposition of immune complexes, the induction of neutrophil apoptosis, the formation of neoantigens between the drugs and proteins from the host, the shift of the immune response, and others. Although the diagnosis is difficult, because the clinical picture of drug-induced CV is in general indistinguishable from that of other forms of CV, it is important to recognize such entities in order to correctly manage the patient. Anamnesis, diagnostic algorithms to assess the likelihood of the association between a drug and a cutaneous reaction, skin biopsy and laboratory testing (including the search for antineutrophil cytoplasmic antibodies) are useful tools to make a diagnosis of drug-induced CV. About the therapy, while in idiopathic vasculitides the treatment is usually more aggressive and long-lasting, very often requiring a maintenance therapy with immunosuppressive drugs, in drug-induced CV the discontinuation of the suspected drug alone is usually enough to achieve complete remission, making the prognosis usually very good.

  6. Use of lomustine to treat cutaneous nonepitheliotropic lymphoma in a cat. (United States)

    Komori, Shinobu; Nakamura, Shinichiro; Takahashi, Kimimasa; Tagawa, Masahiro


    A 17-year-old spayed female domestic shorthair cat was referred for evaluation of severe skin lesions, including ulceration, nodule formation, erythema, and alopecia. Cutaneous nonepitheliotropic lymphoma was diagnosed histologically. There was no evidence of visceral organ involvement, but renal function was decreased. The cat was treated with lomustine (45.5 mg/m2, PO, q 21 d), and skin lesions resolved after administration of the third dose. No severe toxicoses were identified. Results suggest that lomustine may be useful for treatment of cutaneous nonepitheliotropic lymphoma in cats; however, optimal dosage, efficacy, and potential adverse effects must be determined.

  7. WHO-EORTC classification for cutaneous lymphomas. (United States)

    Willemze, Rein; Jaffe, Elaine S; Burg, Günter; Cerroni, Lorenzo; Berti, Emilio; Swerdlow, Steven H; Ralfkiaer, Elisabeth; Chimenti, Sergio; Diaz-Perez, José L; Duncan, Lyn M; Grange, Florent; Harris, Nancy Lee; Kempf, Werner; Kerl, Helmut; Kurrer, Michael; Knobler, Robert; Pimpinelli, Nicola; Sander, Christian; Santucci, Marco; Sterry, Wolfram; Vermeer, Maarten H; Wechsler, Janine; Whittaker, Sean; Meijer, Chris J L M


    Primary cutaneous lymphomas are currently classified by the European Organization for Research and Treatment of Cancer (EORTC) classification or the World Health Organization (WHO) classification, but both systems have shortcomings. In particular, differences in the classification of cutaneous T-cell lymphomas other than mycosis fungoides, Sezary syndrome, and the group of primary cutaneous CD30+ lymphoproliferative disorders and the classification and terminology of different types of cutaneous B-cell lymphomas have resulted in considerable debate and confusion. During recent consensus meetings representatives of both systems reached agreement on a new classification, which is now called the WHO-EORTC classification. In this paper we describe the characteristic features of the different primary cutaneous lymphomas and other hematologic neoplasms frequently presenting in the skin, and discuss differences with the previous classification schemes. In addition, the relative frequency and survival data of 1905 patients with primary cutaneous lymphomas derived from Dutch and Austrian registries for primary cutaneous lymphomas are presented to illustrate the clinical significance of this new classification.

  8. Phthalocyanine photodynamic therapy: disparate effects of pharmacologic inhibitors on cutaneous photosensitivity and on tumor regression. (United States)

    Anderson, C; Hrabovsky, S; McKinley, Y; Tubesing, K; Tang, H P; Dunbar, R; Mukhtar, H; Elmets, C A


    The phthalocyanines are promising second-generation photosensitizers that are being evaluated for the photodynamic therapy (PDT) of malignant tumors. In vivo studies with the silicon phthalocyanine Pc 4 have shown that it is highly effective at causing regression of RIF-1 tumors in C3H/HeN mice in PDT protocols. Because cutaneous photosensitivity is the major complication of photosensitizers used for PDT, experiments were performed to evaluate the effect of inhibitors of the inflammatory response (cyproheptadine, dexamethasone, pentoxifylline, and tumor necrosis factor alpha [TNF-alpha] antibodies) on Pc 4-induced cutaneous photosensitivity and tumor regression. The C3H/HeN mice were injected with either Pc 4 or Photofrin and were exposed to 86 J/cm2 of filtered radiation emitted from a solar simulator. Animals were irradiated at 1, 3, 7, 10, 14 and 28 days postinjection. Cutaneous photosensitivity was assessed using the murine ear-swelling response. Cyproheptadine, dexamethasone, pentoxifylline and TNF-alpha antibodies were administered prior to illumination to assess their ability to block Pc 4-induced cutaneous photosensitivity and to evaluate whether such treatment adversely influenced Pc 4 PDT-induced tumor regression. Compared to Photofrin, Pc 4 produced cutaneous photosensitivity that was transient, resolving within 24 h, and that could be elicited for only 10 days after administration. In contrast, Photofrin caused photosensitivity that required 4 days to resolve and could be elicited for at least 1 month after it was administered. The Pc 4-induced cutaneous photosensitivity could be blocked by corticosteroids and an inhibitor of vasoactive amines (cyproheptadine). The TNF-alpha gene transcription was found to increase in keratinocytes following treatment with Pc 4 and light. The anti-TNF-alpha antibodies and pentoxifylline, an inhibitor of cytokine transcription, also prevented cutaneous photosensitivity, implicating TNF-alpha in the pathogenesis of Pc 4

    Directory of Open Access Journals (Sweden)

    Patel Raksha


    Full Text Available Background: Cutaneous drug reactions are the most common adverse reactions attributed to drugs. Any skin disorder can be imitated, induced or aggravated by drugs. Aims: The present study was carried out to determine the age, sex incidence and clinical pattern of drug eruptions, to recognize offending drugs (self medication or prescribed, to evaluate mortality and morbidity associated with drugs, to educate the patients, and to avoid self-administration of drugs and re-administration of the offending drugs. Methods: The diagnosis of cutaneous drug reactions is mainly based on detailed history and correlation between drug intake and the onset of rash. Two hundred patients (112 males and 88 females presenting with cutaneous drug reactions were studied. Results: Fixed drug eruption was seen in 61 patients; others being urticaria and angioedema, morbilliform rash in 37, pruritus in 25, Stevens Johnson (SJ syndrome in six, purpura in six, exfoliative dermatitis in five, photosensitivity in five, Toxic Epidermal Necrolysis in two, acneiform eruption in three, and erythema multiforme in two patients. The most frequently affected age group was 41-50 years, followed by the 21-30 and 31-40 years age groups. The youngest patient was one year old and the oldest was 80 years old. The period of development of lesions after the intake of drug(s varies from 01-45 days. Cotrimoxazole was the offending drug in 26 cases, followed by Ibuprofen in 20 cases. Conclusions: Fixed drug eruption was the most common drug eruption seen. Cotrimoxazole was the most common cause of drug eruptions.

  10. Primary cutaneous mucormycosis caused by Mucor irregularis in an elderly person. (United States)

    Yamaguchi, Sayaka; Okubo, Yuko; Katano, Azusa; Sano, Ayako; Uezato, Hiroshi; Takahashi, Kenzo


    Primary cutaneous mucormycosis is a rare but often lethal severe fungal infection, which usually occurs in immunocompromised patients. We report a case of primary cutaneous mucormycosis caused by Mucor irregularis in an elderly patient. Seven months after the surgical dissection of the involved skin, cutaneous mucormycosis recurred at the peripheral edge of the skin graft. Shortly subsequent to the administration of liposomal amphotericin B, the remaining skin lesion was excised again. M. irregularis is rarely but increasingly reported as a cause of mucormycosis in immunocompetent individuals, especially in Asian farmers. M. irregularis may be largely disseminated in the soils of Asia and thus the trivial trauma at the time of farm work may be a trigger for the onset. These cases tend to leave severe cosmetic damage even in healthy individuals, although the vital prognosis is not affected.

  11. Cutaneous findings in five cases of malaria

    Directory of Open Access Journals (Sweden)

    Jignesh B Vaishnani


    Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

  12. Cutaneous tuberculosis, tuberculosis verrucosa cutis

    Directory of Open Access Journals (Sweden)

    Nilamani Mohanty


    Full Text Available Cutaneous tuberculosis because of its variability in presentation, wider differential diagnosis, and difficulty in obtaining microbiological confirmation continues to be the most challenging to diagnose for dermatologists in developing countries. Despite the evolution of sophisticated techniques such as polymerase chain reaction (PCR and enzyme-linked-immunosorbent serologic assay (ELISA, the sensitivity of new methods are not better than the isolation of Mycobacterium tuberculosum in culture. Even in the 21 st century, we rely on methods as old as the intradermal reaction purified protein derivative standard test and therapeutic trials, as diagnostic tools. We describe a case which has been diagnosed and treated as eczema by renowned physicians for 2 years. Incisional biopsy showed the presence of well-defined granulomas and ZN staining of the biopsy specimen showed the presence of acid fast bacilli; a trial of ATT (antitubercular therapy for 6 months lead to permanent cure of the lesion.

  13. Treatment Approaches for Cutaneous Leishmaniasis

    Directory of Open Access Journals (Sweden)

    Sema Aytekin


    Full Text Available Cutaneous leishmaniasis (CL is a widespread tropical infection caused by numerous different species of Leishmania protozoa. In our country, CL is due frequently to L. major and L. tropica. Its clinical presentation is extremely diverse. Treatment of CL aims to prevent mucosal invasion, to accelerate the healing of skin lesions, and avoid disfiguring scar. Local and physical treatment modalities including topical paromomycin, cryotherapy, localized controlled heat, carbon dioxide laser therapy, or pentavalant antimonals can be effective against. Intralesional antimonals are still the drug of choice may patients. WHO recommends an injection of drug under edges of the lesions and the entire lesion until the surface has blanched. Parenteral antimonials are useful for large, persistent or recurrent lesions. Combinations with other drugs such as allopurinol, pentoxifylline must be used for antimony unresponsive lesions.

  14. Occupationally Acquired American Cutaneous Leishmaniasis

    Directory of Open Access Journals (Sweden)

    Maria Edileuza Felinto de Brito


    Full Text Available We report two occupationally acquired cases of American cutaneous leishmaniasis (ACL: one accidental laboratory autoinoculation by contaminated needlestick while handling an ACL lesion sample, and one acquired during field studies on bird biology. Polymerase chain reaction (PCR assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples and characterized as Leishmania (Viannia naiffi through an indirect immunofluorescence assay (IFA with species-specific monoclonal antibodies (mAbs and by multilocus enzyme electrophoresis (MLEE. Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis.

  15. Cutaneous T cell lymphoma mimicking cutaneous histiocytosis: differentiation by flow cytometry. (United States)

    Baines, S J; McCormick, D; McInnes, E; Dunn, J K; Dobson, J M; McConnell, I


    A two-year-old, neutered female cross-bred labrador had multiple cutaneous nodules, biopsies of which revealed pathological changes consistent with cutaneous histiocytosis. During a period of one month the dog developed multicentric lymphadenopathy, a retrobulbar mass and masses within the quadriceps and cervical muscles. Fine needle aspiration cytology of the cutaneous nodules and lymph nodes and histological examination of the cutaneous nodules and muscle masses suggested the presence of lymphoblastic lymphoma. A definitive diagnosis of CD8+ T cell lymphoma was achieved by immunophenotyping the tumour cells by flow cytometry.

    Full Text Available Bacillus anthracis is the causative agent of anthrax. Anthrax is a zoonotic disease with three clinical forms. Clinical forms are skin, gastrointestinal and inhalational anthrax. Cutaneous anthrax is 95% of the cases. Cutaneous anthrax frequently defines itself. Clinical presentation of anthrax may be severe and complicated in some cases. There may seem complications like meningitis, septic shock and compartment syndrome. Compartment Syndrome is a rare complication of cutaneous anthrax and it is life threatening. Physicians working in the endemic area should be aware of this form. In this study, three cases were shown which developed compartment syndrome following cutaneous anthrax. J Microbiol Infect Dis 2013;3(4: 214-217

  1. Cutaneous mechanisms of isometric ankle force control

    DEFF Research Database (Denmark)

    Choi, Julia T; Jensen, Jesper Lundbye; Leukel, Christian


    The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force...... of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle...... joint. Understanding how the nervous system normally uses cutaneous feedback in motor control will help us identify which functional aspects are impaired in aging and neurological diseases....

    Mascaro, J M; Herrero, C; Hausmann, G


    Cutaneous manifestations of lupus erythematosus (LE) are, usually, characteristic enough to permit an easy diagnosis. However, some patients may present less typical lesions, associated or not to the classic ones. Therefore, irrespectively of the variety of LE (acute, subacute and chronic), in absence of the typical butterfly rash, erythematosquamous papules or plaques, or any of the characteristic cutaneous alterations, it is important (even though not always easy) to recognize the uncommon and/or atypical changes of the skin.

    Mukai, Kanae; Komatsu, Emi; Nakajima, Yukari; Urai, Tamae; Nasruddin; Sugama, Junko; Nakatani, Toshio


    Cutaneous wound healing is delayed by protein malnutrition (PM). On the other hand, estrogen promotes cutaneous wound healing by its anti-inflammatory and cell proliferation effects. Therefore, we hypothesized that estrogen administration in protein-malnourished ovariectomized (OVX) female mice might improve the inflammatory response and promote cutaneous wound healing as well as normal nutrition. To test this hypothesis, we used full-thickness excisional wounds in Control SHAM, PM SHAM, PM OVX and PM OVX+17β-estradiol mice. The Control diet included 200 g/kg protein and the PM diet included 30 g/kg protein. The ratio of wound area in the Control SHAM group was significantly smaller than those in the three PM groups. In addition, microscopic findings also showed that the ratio of collagen fibers, the ratio of myofibroblasts and the number of new blood vessels in the Control SHAM group were significantly greater than those in the three PM groups. However, the number of Ym1-positive cells as an anti-inflammatory M2-like macrophage marker in the PM OVX+17β-estradiol group was significantly higher than those in the other three groups. These results indicate that the appearance of anti-inflammatory M2-like macrophages was promoted by estrogen administration; however, it could not promote cutaneous wound healing upon a low-protein diet. Therefore, it may be confirmed that nutrition is more important for promoting cutaneous wound healing than estrogen administration.

  8. Cutaneous mechanisms of isometric ankle force control. (United States)

    Choi, Julia T; Lundbye-Jensen, Jesper; Leukel, Christian; Nielsen, Jens Bo


    The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force output. We used repetitive electrical stimulation of the superficial peroneal (foot dorsum) and medial plantar nerves (foot sole) to disrupt cutaneous afferent input in 8 healthy subjects. We measured the effects of repetitive nerve stimulation on (1) tactile thresholds, (2) performance in an ankle force-matching and (3) an ankle position-matching task. Additional force-matching experiments were done to compare the effects of transient versus continuous stimulation in 6 subjects and to determine the effects of foot anesthesia using lidocaine in another 6 subjects. The results showed that stimulation decreased cutaneous sensory function as evidenced by increased touch threshold. Absolute dorsiflexion force error increased without visual feedback during peroneal nerve stimulation. This was not a general effect of stimulation because force error did not increase during plantar nerve stimulation. The effects of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle joint. Understanding how the nervous system normally uses cutaneous feedback in motor control will help us identify which functional aspects are impaired in aging and neurological diseases.

  9. Choroidal Metastases From Cutaneous Melanoma. (United States)

    Mercado, Carmel L; Toy, Brian C; Kistler, Henry B; Moshfeghi, Darius M


    A 92-year-old man presented with months of progressive blurry vision, worsening acutely in his right eye. He denied pain, diplopia, or photopsias. His history was significant for multiple myeloma, prostate cancer, and malignant melanoma of his right shoulder treated with local excision. He had local recurrence with hepatic metastasis of the melanoma treated with radiation and chemotherapy. On examination, his visual acuity was counting fingers in the right eye and 20/60 in the left eye. Amsler grid testing demonstrated metamorphopsia in the right eye. Fundus exam of the right and left eyes revealed multiple, elevated, pigmented choroidal lesions, with associated subretinal fluid in the right macula. This appearance is consistent with hematogenous metastasis of cutaneous malignant melanoma to the choroid and associated serous fluid-causing metamorphopsia. The patient was enrolled in a clinical trial combining plasmid IL-12 with pembrolizumab (Keytruda; Merck, Whitehouse Station, NJ). He passed away 2 months after initial presentation to our clinic.

  10. Vaccinations against cutaneous Leishmania infection. (United States)

    Kronenberg, K; Brosch, S; Von Stebut, E


    Cutaneous leishmaniasis is an endemic disease with increasing incidence, even in Europe. Recently, it has attracted more attention due to reactivation in immunocompromised hosts, e.g. in the context of HIV. Therapeutic options range from topical treatment to systemic therapy for more complex cases. A vaccine does not exist at present. Despite of several attempts, vaccine generation has proven to be difficult even though protective immunity against this obligate intracellular protozoan parasite is dependent on the development of antigen-specific CD4+ and CD8+ T cells capable of releasing IFN?. IFN?, in turn, activates phagocytic host cells to generate oxidative radicals and to eliminate the parasite. This review will describe the basic immunology leading to the development of protective immunity in infected individuals. In addition, the authors will focus on highlighting the different approaches utilized for vaccine development and describe what a efficient vaccine may consist of. Combined intensive research in the fields of basic parasitology and immunology may allow for the generation of an efficacious vaccine against this important human pathogen in the near future.

  11. [Mechanisms of cutaneous drug reactions]. (United States)

    Vaillant, L


    Two main mechanisms, pharmacologic and immunoallergic, are responsible for cutaneous reactions to drugs. Pharmacologic mechanisms can be predictable (overdosage, cumulative or delayed toxicity, adverse effects) or unpredictable (idiosyncratic, intolerance, or anaphylactic reaction). Immunoallergic mechanisms can be mediated by IgE (some types of urticaria and anaphylactic shock), due to circulating immune complexes (leukocytoclastic vasculitis, serum sickness-type reactions) or mediated by lymphocytes (exanthema, Lyell's syndrome, fixed pigmented erythema, photosensitization). The diagnostic work-up varies according to the causative mechanism. When the reaction is predictable, the responsible drug can be identified according to the data in the present bibliography. When the reaction is immunologic, only the chronologic sequence of events can identify the responsible drug. The risk of recurrence with an identical or related molecule also varies according to the causative mechanism. For urticaria, diagnosis and the risk of recurrence differ according to whether the cause is allergic (mediated by IgE or urticarial vasculitis) or is pharmacologic (urticaria due to aspirin or to conversion enzyme inhibitors).

  12. Two cases of cutaneous cryptococcosis. (United States)

    Xiujiao, Xia; Ai'e, Xu


    We report two cases of cutaneous cryptococcosis in male patients without underlying disease. Case 1 had a granulomatous mass on his right neck, gradually enlarging for 3 months. After the mass was debrided surgically in a hospital, the incision wound gradually developed into a severe ulceration. Mycological examination revealed Cryptococcus neoformans infection. It was significant that histopathology of both pre-surgery granuloma and post-surgery ulceration revealed thick-walled spores with thick capsule. Chest X-ray revealed a shadow in the left lower lung. After treatment with amphotec for 21 days, the lesion healed. Case 2 had an approximately 2 x 2 cm solitary dull nodule on his right thigh, which had been present for 8 months. Mycological examination confirmed that the lesion was caused by C. neoformans. The patient's ratio of peripheral blood CD4(+) cell was slightly reduced. After 14 days of treatment with oral fluconazole, followed by oral itraconazole for 2 months, mycological and clinical cure were achieved. The two isolates were identified as C. neoformans var. gattii serotype C and C. neoformans var. grubii serotype A.

  13. Cutaneous interstitial nitric oxide concentration does not increase during heat stress in humans (United States)

    Crandall, C. G.; MacLean, D. A.


    Inhibition of cutaneous nitric oxide (NO) synthase reduces the magnitude of cutaneous vasodilation during whole body heating in humans. However, this observation is insufficient to conclude that NO concentration increases in the skin during a heat stress. This study was designed to test the hypothesis that whole body heating increases cutaneous interstitial NO concentration. This was accomplished by placing 2 microdialysis membranes in the forearm dermal space of 12 subjects. Both membranes were perfused with lactated Ringer solutions at a rate of 2 microl/min. In both normothermia and during whole body heating via a water perfused suit, dialysate from these membranes were obtained and analyzed for NO using the chemiluminescence technique. In six of these subjects, after the heat stress, the membranes were perfused with a 1 M solution of acetylcholine to stimulate NO release. Dialysate from these trials was also assayed to quantify cutaneous interstitial NO concentration. Whole body heating increased skin temperature from 34.6 +/- 0.2 to 38.8 +/- 0.2 degrees C (P heat stress (7.6 +/- 0.7 to 8.6 +/- 0.8 microM; P > 0.05). After the heat stress, administration of acetylcholine in the perfusate significantly increased skin blood flow (128 +/- 6 perfusion units) relative to both normothermic and heat stress values and significantly increased NO concentration in the dialysate (15.8 +/- 2.4 microM). These data suggest that whole body heating does not increase cutaneous interstitial NO concentration in forearm skin. Rather, NO may serve in a permissive role in facilitating the effects of an unknown neurotransmitter, leading to cutaneous vasodilation during a heat stress.

    Marie-Louise Edvinsson; Erik Uddman; Sven E Andersson


    Background Chronic congestive heart failure is a complex condition that leads to dysfunction in the peripheral microcirculation. We have previously shown that vascular reactivity is reduced with increasing age.In this study,we examined a group of very old patients with severe chronic heart failure to test the hypothesis that vascular function is further compromised by a combination of heart failure and aging.Methods Cutaneous forearm blood flow was measured by laser Doppler flownretry and compared among three groups:Group 1 (n=20,men±SE:85.54 years),heart failure patients with New York Heart Association class Ⅳ(NYHA IV) and with a NT-proBNP level =10,mean±SE:67.6 ± 3.0 years),healthy controls with no clinical signs of heart failure.The vasodilator response to the iontophoretic administration of acetylcholine (ACh),acting via an endothelial mechanism,and sodium nitroprusside (SNP),acting via a smooth muscle cell mechanism,were studied. Results All patients with heart failure had significantly reduced vascular reactivity independent of the mode of stimulation (ACh,SNP or heat) when compared to healthy controls.However,the responses did not differ between the two groups of heart failure patients.Conclusions Cutaneous vascular reactivity is reduced in heart failure patients and does not correlate with the severity of the condition or age of patients.

  15. Cutaneous Manifestations of Familial Transthyretin Amyloid Polyneuropathy. (United States)

    Lanoue, Julien; Wei, Nancy; Gorevic, Peter; Phelps, Robert G


    Familial amyloid polyneuropathy (FAP) is a rare inherited autosomal dominant form of systemic amyloidosis, which classically presents with severe motor, sensory, and autonomic dysfunction. Cutaneous involvement does not become clinically apparent until late stage symptomatic disease and is rarely reported in modern literature. Here, the authors review the clinical and histologic cutaneous findings of FAP previously described in the literature and report on 3 patients with unique genetic mutations (Thr60Ala and Gly6Ser; Trp41Leu; Glu89Gln) for which cutaneous involvement has not previously been described. Histologically, our patients showed variable amyloid deposition in the subcutaneous adipose tissue, papillary dermis, and dermal blood vessel walls. A review of the literature suggests cutaneous transthyretin deposition is an underrecognized feature of FAP that occurs early on in disease, even before neural involvement and related symptoms as seen in one of our patients. As such, a cutaneous punch biopsy can serve as quick, easy, and relatively noninvasive diagnostic tool in suspected cases.

  18. The Cutaneous Ciliated Cyst in Young Male: The Possibility of Ciliated Cutaneous Eccrine Cyst (United States)

    Kim, Youngjoon; Kim, Hyunjung


    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

  20. Cutaneous sarcoidosis: A rare case report

    Directory of Open Access Journals (Sweden)

    Bindu Suparna M, Joshi Shivani


    Full Text Available Sarcoidosis is a Greek word (Sarco means flesh and Eido means type or like. Cutaneous sarcoidosis occurs in up to one third of patients with systemic sarcoidosis. This disease is characterised by the presence of non – caseating epitheloid cell granulomas in the skin. Cutaneous sarcoidosis presents as a diagnostic challenge to the dermatopathologists due to its varied presentations and almost identical histologic pictures. Hence, exclusion of infectious causes and compatibility with clinical and radiologic picture serve as significant criteria to come up to a diagnosis. Sometimes; skin lesions are the first manifestation of systemic sarcoidosis. This is not a contagious or allergic disease. There is a risk of development of systemic manifestations at a later date; for which a close follow up is a must. We are presenting a case of cutaneous sarcoidosis, which later on progress to sarcoidosis with systemic manifestations.

  1. [Current diagnosis of cutaneous lupus erythematosus]. (United States)

    Haust, M; Bonsmann, G; Kuhn, A


    Cutaneous lupus erythematosus (CLE) is a disease with different subtypes and the new classification system includes acute CLE (ACLE), subacute CLE (SCLE), chronic CLE (CCLE), and intermittent CLE (ICLE). The broad spectrum of skin involvement and the possibility of systemic organ manifestations at the beginning and during the course of CLE require specific diagnostic procedures. Clinical assessment of the cutaneous manifestations is necessary along with a detailed patient's history. The diagnosis of CLE is confirmed by histopathology and immunofluorescence microscopy. Selective laboratory screening and additional diagnostic procedures depending on clinical symptoms are recommended. Photoprovocation tests can be performed to assess photosensitivity in patients with CLE and to support the diagnosis. Recently, a scoring system for the activity of the cutaneous manifestations in CLE has been developed and is now evaluated in several clinical studies. In this review, the classification and the characteristic clinical criteria of the different CLE subtypes as well as the current diagnostic possibilities are emphasized.

  2. Ovarian carcinoma presenting as cutaneous nasal metastasis* (United States)

    António, Ana Marta; Alves, João Vitor; Goulão, João; Bártolo, Elvira


    Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature.

  4. Subacute cutaneous lupus erythematosus presenting as poikiloderma.

    LENUS (Irish Health Repository)

    Hughes, R


    Subacute cutaneous lupus erythematosus (SCLE) is a recognised variant of lupus erythematosus (LE), which accounts for 10-15% of all cases of cutaneous LE, occurring most commonly in young to middle-aged white women. Diagnosis is based on the detection of anti-Ro\\/SS-A antibodies in the skin and serum, characteristic clinical and histological cutaneous involvement, and relatively mild systemic involvement. Several unusual variants of SCLE have been reported including erythrodermic SCLE, SCLE with vitiligo-like lesions, acral SCLE and bullous SCLE. Poikoilodermatous SCLE is a recognised but rare variant of SCLE. There are currently only two case reports, comprising five individual cases, in the literature. We present a case of SCLE in which the main clinical findings were an extensive photodistributed poikilodermatous rash and alopecia.

  5. Current approach to cutaneous mastocytosis in childhood. (United States)

    Tamay, Zeynep; Özçeker, Deniz


    Mastocytosis is a heterogeneous disorder characterized by clonal proliferation and accumulation of mast cells in one of more organs which may lead to different clinical pictures. Pathological increase and activation of mast cells in various tissues can cause different clinical pictures. Cutaneous mastocytosis limited to the skin is the most typical clinical picture observed in children and systemic mastocytosis is very rare in the pediatric age group. The diagnosis of cutaneous mastocytosis is based on clinical findings, but is often delayed due to lack of clinical awareness of the disease and lack of its consideration in the differential diagnosis. This article focuses on the current diagnosis, management and treatment of cutaneous mastocytosis in children in order to increase awareness about this issue.

  6. Adenocarcinoma of the Rectum with Cutaneous Metastases

    Nohad Hanbala


    Full Text Available Cutaneous metastases of rectal carcinoma is a rare event. It occurs in fewer than 4% of all patients with rectal cancer. When present, it typically signifies a disseminated disease with a poor prognosis. Early detection and proper diagnosis of metastatic rectal cancer can significantly alter treatment and prognosis. We report a 70-year-oldmale who underwent rectal resection with permanent colostomy for rectal adenocarcinoma since seven years. The patient recently developed multiple skin nodules, mainly in his face, scalp, and upper trunk, associated with itching. Fine needle aspiration cytology from a face nodule was done which revealed metastatic adenocarcinoma associated with severe inflammation. Cutaneous metastasis of rectaladenocarcinoma is an unusual event that presents mainly in the form of skin nodules and could be the first sign of metastasis. Early diagnosis of cutaneous metastasis in these patients is important because it can alter treatment and prognosis.

  7. Perforin expression in feline epitheliotropic cutaneous lymphoma. (United States)

    Neta, Michal; Naigamwalla, Dinaz; Bienzle, Dorothee


    Cutaneous lymphomas are uncommon in people and companion animals. The tumors can be broadly categorized into epitheliotropic and nonepitheliotropic forms, which appear to have different biological behaviors. The present case describes a feline cutaneous epitheliotropic lymphoma. Masses in a 9-year-old cat were first identified on the tail. The cat was treated with chemotherapy, but additional skin masses developed on the flank, face, and ears. Local radiation induced transient tumor regression, but eventual dissemination prompted euthanasia 13 months after initial tumor appearance. Granular lymphocytes were consistently detected on blood smears, and histologically, the tumor involved the skin and superficial subcutis. Tumor lymphocytes expressed cluster of differentiation 3 (CD3) and perforin molecules, suggestive of a cytotoxic phenotype. Location, histopathological features, and perforin expression were similar to a distinct entity in human medicine designated primary cutaneous, CD8-positive, epidermotropic, cytotoxic, T-cell lymphoma.

  8. Novel Cutaneous Manifestations of Pleuroparenchymal Fibroelastosis. (United States)

    Lowther, Christopher M; Morrison, Annie O; Candelario, Nicole M; Khalafbeigi, Sheva; Cockerell, Clay J


    Pleuroparenchymal fibroelastosis (PPFE) is a rare progressive disease that manifests as parenchymal fibrosis of the upper lobe and pleura. Approximately 100 cases have been reported. Cutaneous manifestations of PPFE have not previously been described. Diagnosis is dependent on histologic identification of fibrosis with atypical elastic fibers, necessitating an invasive peripheral lung wedge biopsy.A 68-year-old male with a history of pleuroparenchymal fibroelastosis presented with an asymptomatic, telangiectatic erythematous eruption on bilateral lower extremities. Biopsies demonstrated a subtle perivascular infiltrate with marked increase in atypical elastic fibers, similar to the elastosis in the patient's lungs.This is the first documented case of cutaneous manifestations in PPFE. Clinicians need to be aware that cutaneous eruptions clinically simulating telangiectasia macularis eruptiva perstans but lacking a mast cell infiltrate histologically, may have increased abnormal elastic fibers. Thus, early recognition of these lesions in patients with an undefined restrictive lung disorder, may facilitate the diagnosis of PPFE in some patients.

  9. Creation of a virtual cutaneous tissue bank (United States)

    LaFramboise, William A.; Shah, Sujal; Hoy, R. W.; Letbetter, D.; Petrosko, P.; Vennare, R.; Johnson, Peter C.


    Cellular and non-cellular constituents of skin contain fundamental morphometric features and structural patterns that correlate with tissue function. High resolution digital image acquisitions performed using an automated system and proprietary software to assemble adjacent images and create a contiguous, lossless, digital representation of individual microscope slide specimens. Serial extraction, evaluation and statistical analysis of cutaneous feature is performed utilizing an automated analysis system, to derive normal cutaneous parameters comprising essential structural skin components. Automated digital cutaneous analysis allows for fast extraction of microanatomic dat with accuracy approximating manual measurement. The process provides rapid assessment of feature both within individual specimens and across sample populations. The images, component data, and statistical analysis comprise a bioinformatics database to serve as an architectural blueprint for skin tissue engineering and as a diagnostic standard of comparison for pathologic specimens.

  11. Pregnancy-Associated "Cutaneous Type" Pemphigus Vulgaris. (United States)

    Rangel, Javier


    The development of pemphigus, including pemphigus vulgaris (PV) and pemphigus foliaceus, during pregnancy is rare. PV manifests with mucosal and/or cutaneous erosions with flaccid bullae that are histologically characterized by suprabasilar acantholysis. In contrast, pemphigus foliaceus manifests with cutaneous-only involvement and superficial epidermal acantholysis. Enzyme-linked immunosorbent assay specific for autoantibodies against desmoglein 1 and desmoglein 3 aids in the diagnosis and differentiation between pemphigus subtypes. High-dose systemic corticosteroids are first-line agents in management of PV, yet their potential long-term use raises complex management issues associated with pregnancy and fetal risk. Here we report a rare case of cutaneous-limited PV in association with pregnancy.

  12. Diagnosis of Cutaneous Leishmaniasis by Multiplex PCR

    Directory of Open Access Journals (Sweden)

    M Heiat


    Full Text Available Introduction: Annually, more than 14 million people are reported to be infected with Leishmaniasis all over the world. In Iran, this disease is seen in the form of cutaneous and visceral leishmaniasis, of which the cutaneous form is more wide spread. In recent years, cutaneous leishmaniaisis is diagnosed by PCR utilizing specific primers in order to amplify different parasite genes including ribosomal RNA genes, kinetoplast DNA or tandem repeating sequences. The aim of this research was to detect early stage cutaneous leishmaniasis using Multiplex-PCR technique. Methods: In this study, 67 samples were prepared from patients with cutaneous leishmaniasis. DNA was extracted with phenolchloroform. Each specimen was analyzed using two different pairs of PCR primers. The sensitivity of each PCR was optimized on pure Leishmania DNA prior to use for diagnosis. Two standard parasites L. major and L. tropica were used as positive control. Results: DNA amplification fragments were two 115 bp and 683 bp for AB and UL primers, respectively. The sensitivity of two primers was not equal for detection of L. major and L. tropica. The sensivity of PCR with AB primer was 35 cells, while that for UL primer was 40 cells. Conclusion: The results of this study indicate that PCR is a sensitive diagnostic assay for cutaneous leishmaniasis and could be employed as the new standard for routine diagnosis when species identification is not required. However, the ability to identify species is especially important in prognosis of the disease and in deciding appropriate therapy, especially in regions where more than one type of species and disease are seen by clinicians.

    Full Text Available BACKGROUND A wide range of immunologic and non-immunologic causes can lead to the formation of a granuloma. The aetiological agent and immunological status of the host determines the clinical presentation of these chronic skin lesions. However, diagnosis often becomes intricate as different clinical types present with morphological similarities, which gets further complicated by time and presumptive therapy. AIMS To study the incidence and clinical pattern of cutaneous granulomas; their relationship with age, sex, trauma and determine the importance of laboratory tests, specially histopathology in confirming aetiological diagnosis. SETTINGS AND DESIGN Cross-sectional study, based on hospital records. METHODS AND MATERIAL The study was from OPD records of Department of Dermatology and Venereology. All patients who had attended with clinically suspected cutaneous granulomatous lesions and underwent investigative procedures over a one-year period were included in the study. The relevance of the investigative procedures used, especially histopathology in arriving at the final diagnosis was established. Statistical analysis used: Descriptive statistical analysis and Chi-square test whenever appropriate. RESULTS AND CONCLUSIONS A total of 300 cases of cutaneous granuloma were included in the study. There was a male preponderance. The commonest cutaneous granuloma encountered was leprosy followed by fungal and tubercular granuloma. Less frequently encountered forms were syphilis, foreign body, parasitic, lymphogranuloma venereum, actinomycosis, rhinoscleroma, donovanosis and granulomatous mycosis fungoides. A total of 83.39% cases showed clinic-histopathological correlation. Cutaneous granulomas cause diagnostic difficulty due to clinical diversity and mimicry. Cutaneous granulomas of similar origin can present with varied clinical presentations, while those from different backgrounds can have similar presentations. A histopathological examination

    Full Text Available Background: Cutaneous vasculitis presents as a mosaic of clinical and histological findings. Its pathogenic mechanisms and clinical manifestations are varied. Aims: To study the epidemiological spectrum of cutaneous vasculitides as seen in a dermatologic clinic and to determine the clinico-pathological correlation. Methods: A cohort study was conducted on 50 consecutive patients clinically diagnosed as cutaneous vasculitis in the dermatology outdoor; irrespective of age, sex and duration of the disease. Based on the clinical presentation, vasculitis was classified according to modified Gilliam′s classification. All patients were subjected to a baseline workup consisting of complete hemogram, serum-creatinine levels, serum-urea, liver function tests, chest X-ray, urine (routine and microscopic examination besides antistreptolysin O titer, Mantoux test, cryoglobulin levels, antineutrophilic cytoplasmic antibodies and hepatitis B and C. Histopathological examination was done in all patients while immunofluorescence was done in 23 patients. Results: Out of a total of 50 patients diagnosed clinically as cutaneous vasculitis, 41 were classified as leukocytoclastic vasculitis, 2 as Heinoch−Schonlein purpura, 2 as urticarial vasculitis and one each as nodular vasculitis, polyarteritis nodosa and pityriasis lichenoid et varioliforme acuta. Approximately 50% of the patients had a significant drug history, 10% were attributed to infection and 10% had positive collagen workup without any overt manifestations, while 2% each had Wegener granulomatosis and cryoglobulinemia. No cause was found in 26% cases. Histopathology showed features of vasculitis in 42 patients. Only 23 patients could undergo direct immunofluorescence (DIF, out of which 17 (73.9% were positive for vasculitis. Conclusions: Leukocytoclastic vasculitis was the commonest type of vaculitis presenting to the dermatology outpatient department. The workup of patients with cutaneous vasculitis

  15. Cutaneous endometriosis--Surgical presentations of a gynaecological condition. (United States)

    Chiang, David T; Teh, Wan T


    Endometriosis is a common gynaecological condition; cutaneous endometriosis is a subtype of endometriosis. Although cutaneous endometriosis involving the abdominal wall is not common, preoperative diagnosis of cutaneous endometriosis can be easily mistaken for a suture granuloma, lipoma, abscess, cyst or hernia. We report two common surgical presentations of this gynaecological condition.

    Junqueira, Ana Lucia Ariano; Corbett, Ana Maria França; Oliveira Filho, Jayme de; Nasser, Kassila da Rosa; Haddad, Natalie Nejem; Tebet, Ana Carolina Franco


    Cutaneous metastasis is a rare manifestation of visceral malignancies that indicates primarily advanced disease. Due to its low incidence and similarity to other cutaneous lesions, it is not uncommon to have a delayed diagnosis and a shortened prognosis. We describe the case of a patient who presented with a cutaneous nodule in the sternal region as a first sign of malignancy.

  17. Cutaneous leismaniasis with unusual appearance: Case report

    Directory of Open Access Journals (Sweden)

    Havva Erdem


    Full Text Available Leishmaniasis, is a disease that is transmitted by infected sand flies when they suck the blood of mammals. It is estimated that more than 1.5 million new cutaneous leishmaniasis (CL cases occur throughout the world every year and the disease is endemic in southern and southeastern Turkey. Cutaneous leishmaniasis presents a spectrum of manifestations both clinically and histologically. As is in our case, histopathology can be more important than clinical examination.The diagnosis is made by clinical examination and histopathology as well as demonstrating the parasites in the smears obtained from the lesion .In this article, we aimed to present of CL cases with atipic appearance.

  18. Cutaneous metastases presenting as genital ulcer disease

    Directory of Open Access Journals (Sweden)

    S Vasuki


    Full Text Available Cutaneous metastasis from an internal organ malignancy is rare and as, the presenting sign of malignancy is an uncommon phenomenon. Their presence, signals a poor prognosis. We report a case of 50-year-old female who was referred to sexually transmitted diseases - out patient department, with complaints of multiple genital ulcers to rule out sexually transmitted infections. After thorough evaluation, she was found to be a case of carcinoma cervix with metastatic squamous cell carcinomatous deposits on external genitalia. This case was unique because of relatively asymptomatic nature of internal malignancy and atypical presentation of carcinoma cervix as cutaneous metastasis.

    Esmer, Oktay; Karadag, Remzi; Bilgili, Serap Gunes; Gultepe, Bilge; Bayramlar, Huseyin; Karadag, Ayse Serap


    Anthrax is primarily seen in the developing countries, but it can be a worldwide medical concern due to bioterrorism threats. Palpebral anthrax is a rare form of cutaneous anthrax. Untreated cutaneous anthrax can be lethal. Patients with palpebral anthrax can develop complications including cicatrisation and ectropion. Thus, anthrax should be considered in differential diagnosis for patients presenting with preseptal cellulitis in high-risk regions. Herein, we report three anthrax cases (with different age) involving eyelids that were cured without any complications due to early diagnosis and treatment.

    McBride, William J H; Hannah, Rory C S; Le Cornec, Genevera M; Bletchly, Cheryl


    A 23-year-old woman from Vanuatu presented to an Australian hospital with a 3-week history of a non-healing ulcer on the lower leg. A swab was submitted for a multiplex polymerase chain reaction designed to investigate genital ulcerative conditions. Haemophilus ducreyi was detected and the gene product was subsequently sequenced, confirming the diagnosis of cutaneous chancroid. The lesion responded to intramuscular benzathine penicillin. This report adds further evidence that cutaneous chancroid should be considered in the evaluation of skin ulcers in the south Pacific.

  2. Cutaneous malignancies in immunosuppressed organ transplant recipients. (United States)

    Seda, Ivette M Sosa; Zubair, Adeel; Brewer, Jerry D


    During the past century, organ transplantation has delivered the miracle of life to more than 500,000 patients in need. Secondary malignancies have developed as an unforeseen consequence of intense immunosuppressive regimens. Cutaneous malignancies have been recognized as the most frequent cancer that arises post-transplantation. Among organ transplant recipients (OTRs), skin cancer is a substantial cause of morbidity and potential mortality. The authors discuss epidemiology and clinical presentation of cutaneous malignancies; associated risk factors; recommendation for the care of immunosuppressed OTRs, and emerging therapies on the horizon.

  3. Clinical study of cutaneous drug eruptions in 200 patients

    Directory of Open Access Journals (Sweden)

    Raksha M


    Full Text Available Two hundred patients (112 males and 88 females with cutaneous drug eruption were studied. The aim was to recognize the offending drug, to evaluate mortality and morbidity, educate the patient and avoid self-administration and readministration of drugs. Fixed drug eruption was the commonest reaction, seen in 61 patients; other reactions being urticaria and angioedema, morbilliform rash in 37, pruritus in 25, Stevens Johnson Syndrome (SJS in 6, purpura in 6, exfoliative dermatitis in 5, photosensitivity in 5, toxic epidermal necrolysis in 2, acneiform eruption in 3, erythema multiforme in 2. Maximum patients belonged to the age group 41-50, followed by 21-30 and 31-40 years. The youngest was 1 year old and the oldest was 80 years old. Period of development of lesion after intake of drug varied from 1 day to 45 days. Cotrimoxazole was the commonest drug, in 26 cases; followed by Ibuprofen in 20 cases.

  4. Epinephrine as adjuvant for propranolol produces a marked peripheral action in intensifying and prolonging analgesia in response to local dorsal cutaneous noxious pinprick in rats. (United States)

    Tzeng, Jann-Inn; Pan, He-Jia; Liu, Kuo-Sheng; Chen, Yu-Wen; Chen, Yu-Chung; Wang, Jhi-Joung


    The aim of this study was to evaluate the effect of epinephrine as additive for propranolol as an infiltrative anesthetic. Using a rat model of cutaneous trunci muscle reflex (CTMR), we tested the effect of co-administration of epinephrine with propranolol on infiltrative cutaneous analgesia. Bupivacaine, a long-lasting local anesthetic, was used as control. Subcutaneous propranolol and bupivacaine elicited a dose-dependent local anesthetic effect on infiltrative cutaneous analgesia. On the 50% effective dose (ED50) basis, the relative potency was bupivacaine [2.05 (1.95-2.21) μmol/kg]>propranolol [9.21 (9.08-9.42) μmol/kg] (Ppropranolol or bupivacaine) at ED50 or ED95, respectively, intensified and prolonged drug action on infiltrative cutaneous analgesia. Intraperitoneal injection of combined drugs (propranolol or bupivacaine) at ED95 with epinephrine (0.012 μmol/kg) exhibited no cutaneous analgesia. We concluded that propranolol was less potent but produced a similar duration of action when compared to bupivacaine on infiltrative cutaneous analgesia. Epinephrine as adjuvant for propranolol or bupivacaine enhanced the potency and extended the duration of action on infiltrative cutaneous analgesia.

  7. Diagnosis and management of cutaneous vasculitis in children. (United States)

    Ting, Tracy V


    Cutaneous vasculitis in children is rare. Causes of cutaneous vasculitis are varied and are typically differentiated by the affected vessel size. A skin biopsy remains the gold standard for diagnosis but other causes for vasculitis, including systemic conditions, should be considered. This article discusses the childhood conditions commonly presenting with cutaneous vasculitis (leukocytoclastic vasculitis, cutaneous polyarteritis nodosa), biopsy recommendations and findings, and management and potential differential diagnoses, and includes a brief summary of other diseases that may include cutaneous symptoms as a constellation of other systemic findings.

  8. Cutaneous sporotrichosis. Intermittent treatment (pulses) with itraconazole. (United States)

    Bonifaz, Alexandro; Fierro, Leonel; Saúl, Amado; Ponce, Rosa María


    Sporotrichosis is a subcutaneous and exceptionally deep mycosis caused by a dimorphic fungus, Sporothrix schenckii. Itraconazole is a triazole derivative leading to good results in the treatment of sporotrichosis. Patients with cutaneous sporotrichosis proven with mycological tests (direct examination and culture) were enrolled. All patients underwent laboratory tests (at baseline and on a monthly basis) and received oral itraconazole 400 mg/day for one week with a 3-week break (pulses); thereafter the drug was administered as pulses until clinical and mycological cure was achieved. Five patients with sporotrichosis were enrolled, 4 with cutaneous lymphangitic form and one with fixed cutaneous form. Clinical and mycological cure was achieved in 4/5 cases (80%), with a mean number of pulses of 3.5. No patient had side effects and no laboratory test abnormalities occurred. Intermittent or pulsed itraconazole was effective in treating cutaneous sporotrichosis. It may be considered as a new treatment choice that entails an important reduction in total medication use.

  18. [Cutaneous malignant melanoma and the new drugs]. (United States)

    Nieweg, Omgo E; Gallegos-Hernández, José Francisco


    The treatment of cutaneous melanoma has historically been essentially surgical. Much progress has been made in this area, and the resection margins have been established based on tumour depth. Candidates are also identified for lymphadenectomy, avoiding the morbidity of the procedure in patients who do not require it. But little progress has been made in systemic treatment, since the 70's when the use of dacarbazine was introduced for the treatment of patients with tumour progression or distant metastasis, with disappointing results. Despite this, Dacarbazine has been the most used drug to the present. Three years ago, two new drugs were introduced, one of them based on the target therapy and other one in the immunotherapy, offering, with the obtained results, an alternative in the treatment of cutaneous melanoma The objectives of this article are to show the pathways of these drugs, to describe the current role of surgery in cutaneous melanoma, with the arrival of these drugs, as well as to know the therapeutic alternatives that are emerging for the cutaneous melanoma based on scientific evidence.

    Rita Vora


    Full Text Available Cutaneous angiosarcoma is a rare aggressive tumor of capillary and lymphatic endothelial cell origin. Cutaneous angiosarcoma of the head and neck regions seems to be a distinctive neoplasm with characteristic clinicopathologic features that differ from angiosarcoma in other anatomic locations. Angiosarcoma, regardless of their setting, has a bad prognosis. We presented here a case of 80 years old male, with multiple nontender grouped purple to red hemorrhagic vesicular and bullous lesions over left lower cheek and upper neck area, with bilateral cervical lymph nodes since 1 month. Computed tomography thorax showed nodular opacities in the right upper and midzones. Excisional biopsy showed characterstic "dissection of collagen" with mild nuclear atypia. Immunohistochemistry showed tumor cell positive for CD-31 and Fli-1. Patient died within 1 month of presentation.

    WATANABE, Ken-ichi; CHAMBERS, James K.; UCHIDA, Kazuyuki; NIBE, Kazumi; USHIO, Nanako; HORIUCHI, Noriyuki; KOBAYASHI, Yoshiyasu; NAKAYAMA, Hiroyuki


    The atypical cutaneous tumor of a 9-year-old mixed breed female dog was examined. The tumor was well-demarcated and histologically composed of a trichoblastic area, tricholemmal area and apocrine glandular area. Neoplastic cells in trichoblastic area and tricholemmal area had PAS-positive granules in the cytoplasm and were positive for pan-cytokeratin, cytokeratin 5/6, 14 and 19 and p63. Neoplastic cells in trichoblastic area were also positive for cytokeratin 15 and CD34. Neoplastic cells in apocrine glandular area were positive for pan-cytokeratin and cytokeratin 7, 18 and 19. Myoepithelial cell proliferation with osteocartilaginous metaplasia was observed in this area. Since neoplastic cells showed multiphenotypic differentiation for hair follicles and apocrine glands, the present case was diagnosed as a cutaneous mixed tumor. PMID:28132963

  6. Cutaneous Manifestations of Toxoplasmosis: a Case Report

    Directory of Open Access Journals (Sweden)

    Marina Sonya


    Full Text Available Although toxoplasmosis is one of the most widely spread infections in the world, types that involve the skin are extremely rare. However, skin lesions are not specific; moreover, they are quite diverse, which makes the diagnosis of cutaneous toxoplasmosis rather difficult. Thus, differential diagnosis should include a number of other diseases. We present a case of a 43-year-old immunocompetent man with multiple livid erythematous papules and nodules with yellowish discharge that involved the skin of the body and the extremities. By using electro-chemiluminescence immunoassay, immunoglobulin G antibodies to Toxoplasma gondii were detected in the serum, confirming the diagnosis of toxoplasmosis. The treatment with pyrimethamine and trimethoprim-sulfamethoxazole led to complete resolution of skin lesions. In conclusion, although rare in the dermatological practice, cutaneous toxoplasmosis should be considered in all patients presenting with lymphadenopathy, non-specific skin eruptions, especially nodular and colliquative, blood eosinophilia and histological findigs revealing abundant eosinophilic inflitrations.

    Mariana Aris


    Full Text Available We will revisit the dual role of the immune system in controlling and enabling tumor progression, known as cancer immunoediting. We will go through the different phases of this phenomenon, exposing the most relevant evidences obtained from experimental models and human clinical data, with special focus on Cutaneous Melanoma, an immunogenic tumor per excellence. We will describe the different immunotherapeutic strategies employed and consider current models accounting for tumor heterogeneity. And finally, we will propose a rational discussion of the progress made and the future challenges in the therapeutics of Cutaneous Melanoma, taking into consideration that tumor evolution is the resulting from a continuous feedback between tumor cells and their environment, and that different combinatorial therapeutic approaches can be implemented according to the tumor stage.

    Abuelo, J G; Schwartz, S T; Reginato, A J


    A 27-year-old woman undergoing long-term hemodialysis developed cutaneous calcifications on her fingers. A skin biopsy specimen showed that the deposits were calcium oxalate. To our knowledge, only one previous article has reported pathologic and crystallographic studies on calcifications of the skin resulting from dialysis oxalosis. We speculate that vitamin C supplements, liberal tea consumption, an increased serum ionized calcium concentration, and the long duration of hemodialysis contributed to the production of these deposits.

    Mucormycosis is most common in immunocompromised patients, but it can also occur in healthy hosts, most frequently as primary cutaneous mucormycosis (PCM) and predominantly as a result of skin trauma. We present an uncommon case of PCM in a healthy, young man with no previous history of local trauma. Despite rapid progression of the infection, the patient was successfully treated through surgical intervention and by administering liposomal amphotericin B and posaconazole. He made a full recovery without the need for skin grafting.

  14. Primary Cutaneous Histoplasmosis Masquerading as Lepromatous Leprosy (United States)

    Rani, Poonam; Aggarwal, Radhika; Kaushal, Seema


    Histoplasmosis is a genus of dimorphic fungi having various varieties of which the commonest one causing infection is Histoplasma capsulatum known to cause histoplasmosis. It has a varied disease spectrum ranging from an acute infection to chronic disease especially in lungs, disseminated disease and cutaneous disorder. Histoplasma capsulatum usually causes subclinical infection and serious infections only manifest in immunocompromised patients. Frank cases of infection are seen in pulmonary histoplasmosis. The spores of these organisms are seen to be strongly associated with droppings of birds and bats. A combination of these droppings and some soil types provide for an excellent environment for the proliferation of spores. Pulmonary histoplasmosis and disseminated disease are very common in AIDS patients and are a great cause of morbidity and mortality in these patients. Primary cutaneous histoplasmosis is very rare and occurs due to penetrating injuries. Once diagnosis is made, the lesions respond very well to oral itraconazole, fluconazole or amphotericicn B. We report a rare case of Cutaneous Histoplasmosis (CHP) in a 70-year-old male with complaints of multiple nodules all over his body in a HIV seronegative and otherwise immunocompetent patient.

  15. Chronic iritis associated with cutaneous leukocytoclastic vasculitis. (United States)

    Lambert, Jessica; Rodriguez, Alexis; Pearcy-Baluyot, Mischelle; Shahi, Sanjeet K


    Cutaneous leukocytoclastic vasculitis (LCV) is a systemic condition that can be associated with iritis. LCV is characterized as a small-vessel vasculitis of the cutaneous area. The disease demonstrates purple lesions on the skin due to the destruction of small cutaneous blood vessels. These lesions are palpable and most often coalesce forming larger patches on the surface of the skin. During early stages of LCV, the disease can be undetected due to the infrequency and small size of the skin lesions. As such, the patient might go undiagnosed for years while having symptoms of LCV or iritis of unknown etiology. This article discusses the correlation seen with LCV and iritis. We report a case on a patient that presented to our clinic with a history of bilateral chronic iritis. After extensive laboratory testing, we concluded that the chronicity of her iritis was due to her LCV. The correlation between LCV and iritis was not evident for several years in our patient. We also discuss the correlation with systemic Sjogren's syndrome and LVC and how these two separate diseases are linked in many patients. We will illustrate the importance of serological testing, imaging, and skin lesion biopsy for the diagnosis of LCV.

This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the possible therapeutic strategies for the management of the syndrome. Seventeen studies about ACNES therapy were reviewed; of them, 15 were case–control studies, case series, or case reports, and two were randomized controlled trials. The presently available management strategies for ACNES include trigger point injections (diagnostic and therapeutic, ultrasound-guided blocks, chemical neurolysis, and surgical ­neurectomy, in combination with systemic medication, as well as some emerging techniques, such as radiofrequency ablation and neuromodulation. An increased awareness of the syndrome and the use of specific diagnostic criteria for its recognition are required to facilitate an early and successful management. This review compiles the proposed ­management strategies for ACNES. Keywords: anterior cutaneous nerve entrapment syndrome, intercostal, neuralgia, management

  17. Cutaneous natural killer/T-cell lymphoma. (United States)

    Radonich, Michael A; Lazova, Rossitza; Bolognia, Jean


    Lymphomas are classified as either Hodgkin's or non-Hodgkin's. The 2 subtypes of non-Hodgkin's lymphoma that can present primarily in the skin are cutaneous T-cell lymphoma and cutaneous B-cell lymphoma, both of which tend to be low-grade malignant neoplasms. Recently another distinct subtype of lymphoma was discovered, the natural killer (NK)/T-cell lymphoma, which can involve the skin in a primary or secondary fashion. The NK/T-cell subtype of lymphoma is characterized by the expression of the NK-cell antigen CD56. These CD56(+) lymphomas are further subdivided into nasal NK/T-cell lymphomas that commonly present as midfacial destructive disease and non-nasal NK/T-cell lymphomas that often arise in extranodal locations, including the skin. We report a case of aggressive NK-cell leukemia/lymphoma with numerous secondary cutaneous lesions and review the clinical and histopathologic spectrum of non-nasal CD56(+) lymphomas, with an emphasis on the dermatologic findings.

  18. Cutaneous findings in patients with acromegaly. (United States)

    Akoglu, Gulsen; Metin, Ahmet; Emre, Selma; Ersoy, Reyhan; Cakir, Bekir


    Acromegaly is a systemic syndrome caused by overproduction of growth hormone. The syndrome affects cutaneous, endocrine, cardiovascular, skeletal, and respiratory systems. Cutaneous manifestations of acromegaly are various, usually being the first presenting findings of the disease. Forty-nine patients with acromegaly, followed-up at a tertiary referral hospital, underwent dermatological examination. There were 27 (55.1%) female and 22 (44.9%) male patients. The age at onset of the disease was older in females than males (P=0.045). Most patients had acral enlargements, large triangular nose, coarse face, thickened lower lip, and prognathism. Fourteen (28.6%) patients had multiple cherry angiomas, five (10.2%) had varicose veins in lower limbs, and two (4.1%) had psoriasis. In conclusion, a wide spectrum of cutaneous symptoms and features may be associated with acromegaly. Detailed dermatological examination of patients with acromegaly should be an essential component of systemic evaluation. Future prospective studies investigating the relationships between changes in skin signs, hormone levels, and response to treatments may help understand details of skin involvement in acromegaly.

  19. Infiltrative Cutaneous Hemangiolipoma in a Goat

    Directory of Open Access Journals (Sweden)

    Jessica R. Collier


    Full Text Available An approximately 4-year-old castrated male, Saanen cross goat presented to the Colorado State University Veterinary Teaching Hospital for evaluation and removal of a 22 cm × 22 cm, dark red, thickened, and crusted cutaneous lesion along the left ventrolateral thorax. An initial incisional biopsy performed approximately 8 weeks earlier was suspicious for cutaneous hemangiosarcoma. Surgical excision was deemed to be the most appropriate treatment option for this goat. A complete physical exam, complete blood count, and chemistry profile were performed and results were within normal limits. Thoracic radiographs and abdominal ultrasound were performed to rule out metastatic disease and comorbid conditions; no metastatic lesions or other abnormalities were observed. En bloc surgical excision of the affected skin was performed and the entire tissue was submitted for histopathology. A final diagnosis of cutaneous hemangiolipoma was reached upon extensive sectioning and histologic examination of the larger tissue specimen. The goat recovered well from surgery and has had no further complications up to 9 months postoperatively. To our knowledge, this is the first case report of a hemangiolipoma in a goat and surgical excision for such lesions appears to be a viable treatment method.

  20. [Cutaneous nocardiosis as an opportunistic infection]. (United States)

    Bogaard, H J; Erkelens, G W; Faber, W R; de Vries, P J


    A 46-year-old man who had been treated with azathioprine and budesonide for Crohn's disease for the past eight years developed a purulent skin condition on the right ring finger. Despite surgical drainage and treatment with amoxicillin and flucloxacillin, the condition spread itself over the hand and lower arm, partly per continuum and partly in jumps. The patient did not feel ill and there were no systemic symptoms. Ultimately, Nocardia asteroides was cultured from the wound and complete cure was achieved after 8 months' treatment with co-trimoxazole. Infections with Nocardia spp. are rare but may occur more often and run a more fulminant course in patients under treatment with immunosuppressants. Cutaneous nocardiosis generally has a characteristic lymphogenous spreading pattern, but an atypical picture with pustules, pyoderma, cellulitis or abscess formation is also possible. In non-cutaneous nocardiosis there is usually pneumonia or lung abscess, possibly with secondary haematogenous spread to the central nervous system or skin. Culturing Nocardia requires more time than usual but can be promoted by special culture media. Treatment of the infection with co-trimoxazole is the method of choice and is almost always successful in cases of cutaneous nocardiosis.

  1. Muscle metaboreceptor modulation of cutaneous active vasodilation (United States)

    Crandall, C. G.; Stephens, D. P.; Johnson, J. M.


    PURPOSE: Isometric handgrip exercise in hyperthermia has been shown to reduce cutaneous vascular conductance (CVC) by inhibiting the cutaneous active vasodilator system. METHODS: To identify whether this response was initiated by muscle metaboreceptors, in seven subjects two 3-min bouts of isometric handgrip exercise in hyperthermia were performed, followed by 2 min of postexercise ischemia (PEI). An index of forearm skin blood flow (laser-Doppler flowmetry) was measured on the contralateral arm at an unblocked site and at a site at which adrenergic vasoconstrictor function was blocked via bretylium iontophoresis to reveal active cutaneous vasodilator function unambiguously. Sweat rate was measured via capacitance hygrometry, CVC was indexed from the ratio of skin blood flow to mean arterial pressure and was expressed as a percentage of maximal CVC at that site. In normothermia, neither isometric exercise nor PEI affected CVC (P > 0.05). RESULTS: The first bout of isometric handgrip exercise in hyperthermia reduced CVC at control sites and this reduction persisted through PEI (pre-exercise: 59.8 +/- 5.4, exercise: 49.8 +/- 4.9, PEI: 49.7 +/- 5.3% of maximum; both P vasodilator system, is primarily mediated by muscle metaboreceptors, whereas central command or muscle mechanoreceptors have less influence.

    Full Text Available Minor surgery is a general surgical procedure that applied with minimally invasive procedures and short duration, done in a superficial or just the affected tissue.  This technique is normally only requires a local anaesthetic and only has minimal  risk or complications. There are many cases that could be dealt with minor surgery one is veruka. Veruka or known as cutaneous warts is a disease that is often complained in children and adults. Veruka being estimated to occur until over 10% in children and young adults. Largest incident occurred in range of age 12 to 16 years. Veruka occurs more frequently in women than men. The peak incidence occur of age 13 years on women and 14.5 years in males. Salicylic acid and cryosurgery therapy are two of the most frequently performed in the treatment of cutaneous warts. Salicylic acid is therapy  for cutaneous warts who recently had already started replaced by cryosurgery because it is relatively easy to do and faster recovery.  

  3. Congenital cutaneous histiocytosis in a piglet. (United States)

    Hélie, P; Kiupel, M; Drolet, R


    A 2-week-old crossbred male piglet with numerous congenital, variably sized macules, plaques, and papules distributed all over the body was submitted for necropsy. Significant gross and histological lesions were restricted to the skin. On light microscopic examination, these cutaneous lesions corresponded to dermal and/or subcutaneous masses composed of spindle-shaped to round cells that multifocally contained hemosiderin; epidermotropism was not observed. Immunohistochemically, the neoplastic cells were strongly positive for CD204; moderately positive for CD163, lysozyme, and vimentin; and negative for Mac 387, α-1-antitrypsin, S-100 protein and E-cadherin; frozen tissues were not available for CD1a and CD11c. Transmission electron microscopic examination of sections from formalin-fixed tissues did not reveal Birbeck's granules. The clinical, morphological, and immunohistochemical results were consistent with a congenital cutaneous histiocytosis of non-Langerhans cell origin. The condition most resembled juvenile xanthogranuloma in humans, a generally skin-limited non-Langerhans histiocytic disorder that can be congenital. Cutaneous and/or systemic histiocytic disorders are well characterized in dogs and have been described in cats, and a case with some similarities to ours has been reported in a neonatal piglet, but this is to our knowledge the first immunohistochemically supported report of histiocytosis in the pig and congenital histiocytosis in animals.

  4. Cutaneous pancreatic metastasis: a case report and review of literature. (United States)

    Hafez, Hza


    Pancreatic cancer is one of the most lethal human cancers and continues to be a major unsolved health problem as we enter the 21st century. This is the case despite advances in imaging technology and surgical management. Indeed, 80-90% of pancreatic cancers are diagnosed either at the locally advanced stage or metastatic stage. Cutaneous metastases originating from pancreatic cancer are relatively rare. The most common site of cutaneous metastasis is the umbilicus, and it is known as the Sister Joseph's nodule. Very few patients have been reported with cutaneous lesions disclosing pancreatic carcinoma at sites other than the umbilical area. To our knowledge, there were no previous reports on cutaneous pancreatic metastasis in Egypt. This is a report of a patient with cutaneous pancreatic metastases at the neck, followed by a review of reported non-umbilical cutaneous metastases from pancreatic carcinoma in the literature.

  5. Low-threshold, short-latency cutaneous reflexes during fictive locomotion in the "semi-chronic" spinal cat. (United States)

    LaBella, L A; Niechaj, A; Rossignol, S


    Low-threshold, short-latency cutaneous reflexes evoked in ipsilateral hindlimb motor nerves were examined during fictive locomotion. Locomotion in 11 anaemically decerebrated spinal animals (1-3 weeks after transection at T13-L1) was induced by administration of clonidine, L-dopa and nialamide; by administration of the latter two drugs only; or by exteroceptive stimulation in the absence of any drugs. The caudal and lateral cutaneous sural, caudal cutaneous femoral, saphenous and superficial peroneal nerves were stimulated at low threshold (1.5-3 T). Pooled results from all combinations of cutaneous nerves stimulated and muscle nerves recorded show that the initial response was excitatory in 40 of 50 triceps surae and 17 of 20 semitendinosus (St) electroneurograms (ENGs). These excitatory responses occurred at latencies that ranged from 5 to 15 ms and tended to be maximal during the motor nerve's active period in the step cycle (i.e. they were modulated in a phase-dependent manner). Only three inhibitory responses (9-12 ms earliest latency) were encountered in total: in two St ENGs of one animal and in one lateral gastrocnemius-soleus ENG of a different animal. In two animals a "second" excitatory response (15-25 ms latency) was sometimes recorded in triceps surae and St nerves and, interestingly, could be modulated out of phase with the early response. Weak short-latency excitatory reflexes were also found in contralateral St ENGs when examined. Finally, among medial gastrocnemius, lateral gastrocnemius and soleus nerves, excitatory responses due to stimulation of any particular cutaneous nerve tended to be modulated similarly but were of consistently different amplitude among the three. This finding, together with the general observation that excitatory reflexes produced by stimulation of a particular cutaneous nerve were modulated similarly in extensors (or flexors) of different animals, suggests that spinal circuits generating locomotion may indeed exert a

  6. Clinical implications of immunologic phenotyping in cutaneous T cell lymphoma. (United States)

    Vonderheid, E C; Tan, E; Sobel, E L; Schwab, E; Micaily, B; Jegasothy, B V


    The composition of cutaneous lesions from 158 patients with confirmed cutaneous T cell lymphoma, 91 patients with suspected cutaneous T cell lymphoma, and 145 patients with lymphoid disorders other than cutaneous T cell lymphoma was quantitated in situ with the use of commercially available murine monoclonal antibodies that identify the Pan T, T-helper/inducer (Th), T cytotoxic/suppressor (Ts), and Pan B lymphocyte subsets. On average, cutaneous infiltrates of confirmed cutaneous T cell lymphoma were found to contain significantly more Th and less Ts or Pan B cells compared to benign lymphoid disorders. Moreover, when analyzed in terms of the type of lesion examined by biopsy, the absolute amount of Th cells progressively expands with increasing magnitudes of infiltrate in the dermis while the amount of Ts and Pan B cells remains relatively constant among lesions. A useful diagnostic criterion (anti-Leu 1/4 greater than or equal to 70% and anti-Leu 3a/anti-Leu 2a ratio greater than or equal to 6) correctly discriminated between cutaneous T cell lymphoma and non-cutaneous T cell lymphoma in 87.5% of cases. A positive immunodiagnostic result also may be useful for the prediction of subsequent histopathologic confirmation of cutaneous T cell lymphoma in patients who have suspect lymphoid infiltrates, such as alopecia mucinosis or idiopathic generalized erythroderma, when first seen. With the use of multivariate analysis, stage and possibly the percentage of Th cells within the T cell component in cutaneous infiltrates were covariates with significant relationships to survival in patients with confirmed cutaneous T cell lymphoma. In addition, Ts cells in infiltrates did not correlate significantly with observed responses to topical treatment and subsequent course in pretumorous mycosis fungoides. These results indicate that Ts cells play little biologic role in modifying the natural history of cutaneous T cell lymphoma.

  7. Cutaneous metastases from head and neck squamous cell carcinoma. (United States)

    Poovaneswaran, Sangeetha; Paleri, Vinidh; Charlton, Fraser; Dobrowsky, Werner; Kelly, Charles


    The presence of cutaneous metastases in squamous cell carcinomas of the head and neck (SCCHN) is rare and associated with a dismal prognosis. It is vital to distinguish these lesions from direct invasion of the skin by SCCHN or primary cutaneous malignancies as the prognosis is vastly different and so is the management. In this case report, we present four cases of cutaneous metastases and also briefly review the literature pertaining to this phenomenon.

  8. Periorbital mucinosis: a variant of cutaneous lupus erythematosus? (United States)

    Morales-Burgos, Adisbeth; Sánchez, Jorge L; Gonzalez-Chávez, José; Vega, Janelle; Justiniano, Hildamari


    Lupus erythematosus has a wide spectrum of cutaneous manifestations, including periorbital mucinosis. We report 3 cases of periorbital mucinosis occurring in association with other cutaneous signs of lupus erythematosus. Based on a review of the literature, periorbital mucinosis is a rare and not widely recognized clinical manifestation of the disease. Although unusual, familiarity with periorbital mucinosis as a manifestation of lupus erythematosus broadens our understanding of these entities and expands the spectrum of cutaneous lupus erythematosus.

    Full Text Available Mucorales are saprophytic fungi causing mucormycosis, which is a life threatening infection manifested as rhinocerebral, pulmonary, gastrointestinal, cutaneous, and disseminated forms. The cutaneous form is further divided into primary and secondary forms. The major risk factors include uncontrolled diabetes mellitus with or without ketoacidosis, other forms of metabolic acidosis, and trauma. We report here a case of primary cutaneous mucormycosis caused by Rhizopus oryzae, in a diabetic after a road traffic accident.

    Full Text Available Cutaneous manifestations of Lyme borreliosis in Europe include erythema migrans (EM and acrodermatitis chronica atrophicans (ACA; the most common non-cutaneous manifestations are Lyme neuroborreliosis (LNB and Lyme arthritis. The purpose of this study was to evaluate the gender distribution of patients with these clinical manifestations of Lyme borreliosis. Data on gender were obtained from the clinical records of patients with Lyme borreliosis aged ≥15 years who had been evaluated at the University Medical Center Ljubljana, Ljubljana, Slovenia. Among 10,539 patients diagnosed with EM, 6,245 (59.3% were female and among 506 ACA patients 347 (68.6% were female. In contrast, among the 60 patients with Lyme arthritis only 15 (25% were female (p<0.0001 for the comparison of gender with EM or ACA and among the 130 patients with LNB only 51 (39.2% were females (p<0.0001for the comparison of gender with EM or ACA. Although the proportion that was female in the LNB group was greater than that of patients with Lyme arthritis, this difference did not reach statistical significance (p = 0.10. Although older individuals are more likely to be female in the general Slovenian population, the age of patients with cutaneous versus non-cutaneous manifestations was not the explanation for the observed differences in gender. In conclusion, patients with cutaneous manifestations of Lyme borreliosis were predominantly female, whereas those with non-cutaneous manifestations were predominantly male. This provocative finding is unexplained but may have direct relevance to the pathogenesis of Lyme borreliosis.

    Purpose. - To analyze the therapeutic results of cutaneous cancers on xeroderma pigmentosum through a series of 15 patients treated by radiotherapy. Patients and methods. - Between 1993 and 2006, 15 patients with xeroderma pigmentosum and having cutaneous cancers were treated in the Radiotherapy Department of university hospital Habib-Bourguiba of Sfax in Tunisia. Seventy-three percent of the cases occurred in male patients and the mean age of appearance of the first tumour was 18.2 years. Tumour histology was squamous cell carcinoma in 74% of the cases. The total number of cutaneous tumours was 84. Ten patients had a surgical resection. Four patients did not respond to chemotherapy. The modality of irradiation was decided according to the size, thickness and localization of the tumour. The dose of radiotherapy was 60 Gy or equivalent with classic irradiation. Results. - The total number of lesions treated with radiotherapy was 64. Forty-three lesions were treated with contact-therapy, ten with brachytherapy and 11 with cobalt-therapy. The following acute complications were observed: cutaneous infection (53.3% of patients), radio-epithelitis (80% of patients) and necroses (33.3% of patients). Evaluation after treatment showed a clinical complete remission in 73% of the cases. Late effects were noted in seven cases: telangiectasia and cutaneous atrophy. A recurrence in the irradiated zone was observed in one case. A nodal metastasis was observed in two cases. Another patient presented lung metastases. After a median follow up of 37.2 months, four patients died, seven are alive with cutaneous cancer and four are alive with complete remission. Conclusion. - Radiotherapy is a possible and effective therapeutic alternative. Dose and methods are not defined for xeroderma pigmentosum. (authors)

    Full Text Available A cutaneous horn is a general name for cornified material protruding from skin. On the other hand, polydactyly is a common congenital anomaly of the hand and foot which is characterized by extra finger or toe. A cutaneous horn might mimick polydactyly by resembling an extra toe. Hereby, we present a 72-year-old white Caucasian male with an extra toe-like projection on his fourth toe. Initially, polydactyly was suspected, however a cutaneous horn was also considered. The lesion was surgically removed. The histopathological examination of the specimen revealed hyperkeratosis, and thus confirmed the  lesion to be a cutaneous horn.

  14. Impaired acetylcholine-induced cutaneous vasodilation in young smokers: roles of nitric oxide and prostanoids. (United States)

    Fujii, Naoto; Reinke, Maggie C; Brunt, Vienna E; Minson, Christopher T


    Cigarette smoking attenuates acetylcholine (ACh)-induced cutaneous vasodilation in humans, but the underlying mechanisms are unknown. We tested the hypothesis that smokers have impaired nitric oxide (NO)- and cyclooxygenase (COX)-dependent cutaneous vasodilation to ACh infusion. Twelve young smokers, who have smoked more than 5.2 ± 0.7 yr with an average daily consumption of 11.4 ± 1.2 cigarettes, and 12 nonsmokers were tested. Age, body mass index, and resting mean arterial pressure were similar between the groups. Cutaneous vascular conductance (CVC) was evaluated as laser-Doppler flux divided by mean arterial pressure, normalized to maximal CVC (local heating to 43.0°C plus sodium nitroprusside administration). We evaluated the increase in CVC from baseline to peak (CVCΔpeak) and area under the curve of CVC (CVCAUC) during a bolus infusion (1 min) of 137.5 μM ACh at four intradermal microdialysis sites: 1) Ringer (control), 2) 10 mM N(G)-nitro-l-arginine methyl ester (l-NAME; NO synthase inhibitor), 3) 10 mM ketorolac (COX inhibitor), and 4) combination of l-NAME + ketorolac. CVCΔpeak and CVCAUC at the Ringer site in nonsmokers were greater than in smokers (CVCΔpeak, 42.9 ± 5.1 vs. 22.3 ± 3.5%max, P vasodilation in young smokers is related to diminished NO- and COX-dependent vasodilation.

  16. Topical Application of Fingolimod Perturbs Cutaneous Inflammation. (United States)

    Sun, Wai Y; Dimasi, David P; Pitman, Melissa R; Zhuang, YiZhong; Heddle, Robert; Pitson, Stuart M; Grimbaldeston, Michele A; Bonder, Claudine S


    The prevalence of allergies, including rhinitis, eczema, and anaphylaxis, is rising dramatically worldwide. This increase is especially problematic in children who bear the greatest burden of this rising trend. Increasing evidence identifies neutrophils as primary perpetrators of the more severe and difficult to manage forms of inflammation. A newly recognized mechanism by which neutrophils are recruited during the early phase of histamine-induced inflammation involves the sphingosine kinase (SK)/sphingosine-1-phosphate axis. This study examines whether topical application of fingolimod, an established SK/sphingosine-1-phosphate antagonist already in clinical use to treat multiple sclerosis, may be repurposed to treat cutaneous inflammation. Using two mouse models of ear skin inflammation (histamine- and IgE-mediated passive cutaneous anaphylaxis) we topically applied fingolimod prophylactically, as well as after establishment of the inflammatory response, and examined ear swelling, SK activity, vascular permeability, leukocyte recruitment, and production of proinflammatory mediators. The present study reveals that when applied topically, fingolimod attenuates both immediate and late-phase responses to histamine with reduced extravasation of fluid, SK-1 activity, proinflammatory cytokine and chemokine production, and neutrophil influx and prevents ear swelling. Intravital microscopy demonstrates that histamine-induced neutrophil rolling and adhesion to the postcapillary venules in the mouse ears is significantly attenuated even after 24 h. More importantly, these effects are achievable even once inflammation is established. Translation into humans was also accomplished with epicutaneous application of fingolimod resolving histamine-induced and allergen-induced inflammatory reactions in forearm skin. Overall, this study demonstrates, to our knowledge for the first time, that fingolimod may be repurposed to treat cutaneous inflammation.

  17. Platelet gel for healing cutaneous chronic wounds. (United States)

    Crovetti, Giovanni; Martinelli, Giovanna; Issi, Marwan; Barone, Marilde; Guizzardi, Marco; Campanati, Barbara; Moroni, Marco; Carabelli, Angelo


    Wound healing is a specific host immune response for restoration of tissue integrity. Experimental studies demonstrated an alteration of growth factors activity due to their reduced synthesis, increased degradation and inactivation. In wound healing platelets play an essential role since they are rich of alpha-granules growth factors (platelet derived growth factor--PDGF; transforming growth factor-beta--TGF-beta; vascular endothelial growth factor--VEGF). Topical use of platelet gel (PG), hemocomponent obtained from mix of activated platelets and cryoprecipitate, gives the exogenous and in situ adding of growth factors (GF). The hemocomponents are of autologous or homologous origin. We performed a technique based on: multicomponent apheretic procedure to obtain plasma rich platelet and cryoprecipitate; manual processing in an open system, in sterile environment, for gel activation. Every step of the gel synthesis was checked by a quality control programme. The therapeutic protocol consists of the once-weekly application of PG. Progressive reduction of the wound size, granulation tissue forming, wound bed detersion, regression and absence of infective processes were considered for evaluating clinical response to hemotherapy. 24 patients were enrolled. They had single or multiple cutaneous ulcers with different ethiopathogenesis. Only 3 patients could perform autologous withdrawal; in the others homologous hemocomponent were used, always considering suitability and traceability criteria for transfusional use of blood. Complete response was observed in 9 patients, 2 were subjected to cutaneous graft, 4 stopped treatment, 9 had partial response and are still receiving the treatment. In each case granulation tissue forming increased following to the first PG applications, while complete re-epithelization was obtained later. Pain was reduced in every treated patient. Topical haemotherapy with PG may be considered as an adjuvant treatment of a multidisciplinary process

  18. Cutaneous and systemic complications associated with tattooing. (United States)

    Kluger, Nicolas


    Tattooing can result in a wide variety of complications, whose prevalence and incidence remain still unclear. Hypersensitivity reactions (or allergies) to tattoo pigments are currently the most common complication on a tattoo, however they are not predictable. Infections are nowadays directly related to the lack of asepsis and hygiene during the tattooing procedure or during the healing phase. Patients with a known cutaneous disease should be warned of a potential risk of localization of their disease to the tattoo. A skin eruption restricted to a tattoo may reveal sarcoidosis. Patients with chronic conditions and/or impaired immunity should discuss with their physician about the possibility and when to have a tattoo.

  19. Massive zosteriform cutaneous metastasis from rectal carcinoma. (United States)

    Damin, D C; Lazzaron, A R; Tarta, C; Cartel, A; Rosito, M A


    A 44-year-old man presented with a large and rapidly growing skin lesion approximately six months after resection of a rectal carcinoma. The lesion measured 40 cm in size, extended from the suprapubic area to the proximal half of the left groin, and showed a particular zosteriform aspect. Biopsy confirmed a metastatic skin adenocarcinoma. Cutaneous metastases from rectal cancer are very uncommon. Their gross appearance is not distinctive, although the skin tumors are usually solid, small (less than 5 cm) and painless nodules or papules. Early biopsies for suspicious skin lesions are needed in patients with a history of colorectal cancer.

    Full Text Available Drug hypersensitivity is an unpredictable, immunologically mediated adverse reaction, clustered in a genetically predisposed individual. The role of "hapten concept" in immune sensitization has recently been contested by the "pharmacological interaction" hypothesis. After completion of the "human genome project" and with the availability of high-resolution genotyping, genetic susceptibility to hypersensitivity for certain drugs has been proved beyond doubt though the trend is ethnicity and phenotype dependent. Application of this newly acquired knowledge may reduce or abolish the morbidity and mortality associated with cutaneous drug hypersensitivity.

  3. Dermoscopic patterns of cutaneous melanoma metastases. (United States)

    Rubegni, Pietro; Lamberti, Arianna; Mandato, Filomena; Perotti, Roberto; Fimiani, Michele


    In 2-8% of patients with melanoma, the first clinical manifestation of the disease may be skin metastasis. In these cases, differential diagnosis with the primary melanoma, benign melanocytic lesions, and other malignant and benign skin growths is particularly challenging. For this reason, the dermatologist's approach to cutaneous metastases of malignant melanoma calls for knowledge of the great morphological variety of these lesions. Dermoscopic characteristics associated with CMMMs have not yet been codified. The aim of the present review is to provide additional information about dermoscopic aspects of these skin lesions.

  4. Molecular pathogenesis of cutaneous melanocytic neoplasms. (United States)

    Ibrahim, Nageatte; Haluska, Frank G


    Melanoma is the deadliest form of skin cancer without an effective treatment. An understanding of the genetic basis of melanoma has recently shed light on some of the mechanisms of melanomagenesis. This review explores the major genes involved in familial and sporadic cutaneous melanoma with an emphasis on CDKN2A, CDK4, MC1R, and MAPK pathway targets (e.g., RAS and BRAF), apoptosis regulators (e.g., BCL-2, AKT, and APAF-1), and the tumor-suppressor genes TP53 and PTEN. New directions for therapeutics based on our current knowledge of the genes implicated in melanoma are also discussed.

  5. Cutaneous Force Feedback as a Sensory Subtraction Technique in Haptics. (United States)

    Prattichizzo, D; Pacchierotti, C; Rosati, G


    A novel sensory substitution technique is presented. Kinesthetic and cutaneous force feedback are substituted by cutaneous feedback (CF) only, provided by two wearable devices able to apply forces to the index finger and the thumb, while holding a handle during a teleoperation task. The force pattern, fed back to the user while using the cutaneous devices, is similar, in terms of intensity and area of application, to the cutaneous force pattern applied to the finger pad while interacting with a haptic device providing both cutaneous and kinesthetic force feedback. The pattern generated using the cutaneous devices can be thought as a subtraction between the complete haptic feedback (HF) and the kinesthetic part of it. For this reason, we refer to this approach as sensory subtraction instead of sensory substitution. A needle insertion scenario is considered to validate the approach. The haptic device is connected to a virtual environment simulating a needle insertion task. Experiments show that the perception of inserting a needle using the cutaneous-only force feedback is nearly indistinguishable from the one felt by the user while using both cutaneous and kinesthetic feedback. As most of the sensory substitution approaches, the proposed sensory subtraction technique also has the advantage of not suffering from stability issues of teleoperation systems due, for instance, to communication delays. Moreover, experiments show that the sensory subtraction technique outperforms sensory substitution with more conventional visual feedback (VF).

  6. Cutaneous metastasis from a myoepithelial carcinoma of submandibular salivary gland. (United States)

    Chougule, Abhijit; Barwad, Adarsh; Bal, Amanjit; Dey, Pranab


    Myoepithelial carcinoma is a rare malignant tumor of salivary gland with locally aggressive nature and potential for distant metastasis. It is composed of tumor cells with myoepithelial differentiation showing varied cytomorphology. Lungs and kidneys are the commonest sites for distant metastasis. Cutaneous metastasis of myoepithelial carcinoma is very rare. In this report, we described cutaneous metastasis of myoepithelial carcinoma arising from submandibular gland.

  9. The Role of Neuromediators and Innervation in Cutaneous Wound Healing. (United States)

    Ashrafi, Mohammed; Baguneid, Mohamed; Bayat, Ardeshir


    The skin is densely innervated with an intricate network of cutaneous nerves, neuromediators and specific receptors which influence a variety of physiological and disease processes. There is emerging evidence that cutaneous innervation may play an important role in mediating wound healing. This review aims to comprehensively examine the evidence that signifies the role of innervation during the overlapping stages of cutaneous wound healing. Numerous neuropeptides that are secreted by the sensory and autonomic nerve fibres play an essential part during the distinct phases of wound healing. Delayed wound healing in diabetes and fetal cutaneous regeneration following wounding further highlights the pivotal role skin innervation and its associated neuromediators play in wound healing. Understanding the mechanisms via which cutaneous innervation modulates wound healing in both the adult and fetus will provide opportunities to develop therapeutic devices which could manipulate skin innervation to aid wound healing.

  10. Cutaneous lichen planus: A systematic review of treatments. (United States)

    Fazel, Nasim


    Various treatment modalities are available for cutaneous lichen planus. Pubmed, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, and Health Technology Assessment Database were searched for all the systematic reviews and randomized controlled trials related to cutaneous lichen planus. Two systematic reviews and nine relevant randomized controlled trials were identified. Acitretin, griseofulvin, hydroxychloroquine and narrow band ultraviolet B are demonstrated to be effective in the treatment of cutaneous lichen planus. Sulfasalazine is effective, but has an unfavorable safety profile. KH1060, a vitamin D analogue, is not beneficial in the management of cutaneous lichen planus. Evidence from large scale randomized trials demonstrating the safety and efficacy for many other treatment modalities used to treat cutaneous lichen planus is simply not available.

  12. Disseminated cutaneous histoplasmosis in an immunocompetent adult

    Directory of Open Access Journals (Sweden)

    Manoj Harnalikar


    Full Text Available Histoplasmosis, a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii is endemic to many parts of the world. The clinical manifestations range from acute or chronic pulmonary infection to a progressive disseminated disease. After initial exposure to the fungus, the infection is self-limited and restricted to the lungs in 99% of healthy individuals. The remaining 1%, however, progress to either disseminated or chronic disease involving the lungs, liver, spleen, lymph nodes, bone marrow or rarely, the skin and mucous membranes. Mucocutaneous histoplasmosis is frequently reported in patients with acquired immune deficiency syndrome (AIDS, but it is rare in immunocompetent hosts. A 60-year-old male presented with asymptomatic swelling of the hard palate and crusted papules and nodules over the extremities, face and trunk. Clinically, the diagnoses of cutaneous cryptococcosis versus histoplasmosis was considered in this patient. A chest X-ray revealed hilar lymphadenopathy. Enzyme-linked immunosorbent assay (ELISA for human immunodeficiency virus (HIV was nonreactive. Skin biopsy revealed multiple tiny intracellular round yeast forms with a halo in the mid-dermis. Culture of the skin biopsy in Sabouraud′s dextrose agar showed colonies of Histoplasma capsulatum. Despite an investigation including no evidence of underlying immunosuppression was found, he was started on IV amphotericin-B (0.5 mg/kg/day. However, the patient succumbed to his disease 2 days after presentation. We report a rare case of disseminated cutaneous histoplasmosis in an immunocompetent individual.

  13. Plasmacytoid dendritic cell role in cutaneous malignancies. (United States)

    Saadeh, Dana; Kurban, Mazen; Abbas, Ossama


    Plasmacytoid dendritic cells (pDCs) correspond to a specialized dendritic cell population that exhibit plasma cell morphology, express CD4, CD123, HLA-DR, blood-derived dendritic cell antigen-2 (BDCA-2), and Toll-like receptor (TLR)7 and TLR9 within endosomal compartments. Through their production of type I interferons (IFNs) and other pro-inflammatory cytokines, pDCs provide anti-viral resistance and link the innate and adaptive immunity by controlling the function of myeloid DCs, lymphocytes, and natural killer (NK) cells. While lacking from normal skin, pDCs are usually recruited to the skin in several cutaneous pathologies where they appear to be involved in the pathogenesis of several infectious, inflammatory/autoimmune, and neoplastic entities. Among the latter group, pDCs have the potential to induce anti-tumour immunity; however, the complex interaction of pDCs with tumor cells and their micro-environment appears to contribute to immunologic tolerance. In this review, we aim at highlighting the role played by pDCs in cutaneous malignancies with special emphasis on the underlying mechanisms.

    According to the International Atomic Energy Agency (IAEA), a relatively significant number of radiological accidents have occurred in recent years mainly because of the practices referred to as potentially high-risk activities, such as radiotherapy, large irradiators and industrial radiography, especially in gammagraphy assays. In some instances, severe injuries have occurred in exposed persons due to high radiation doses. In industrial radiography, 80 cases involving a total of 120 radiation workers, 110 members of the public including 12 deaths have been recorded up to 2014. Radiological accidents in industrial practices in Brazil have mainly resulted in development of cutaneous radiation syndrome (CRS) in hands and fingers. Brazilian data include 5 serious cases related to industrial gammagraphy, affecting 7 radiation workers and 19 members of the public; however, none of them were fatal. Some methods of reconstructive dosimetry have been used to estimate the radiation dose to assist in prescribing medical treatment. The type and development of cutaneous manifestations in the exposed areas of a person is the first achievable gross dose estimation. This review article presents the state-of-the-art reconstructive dosimetry methods enabling estimation of local radiation doses and provides guidelines for medical handling of the exposed individuals. The review also presents the Chilean and Brazilian radiological accident cases to highlight the importance of reconstructive dosimetry. (author)

  15. Anterior cutaneous nerve entrapment syndrome: management challenges (United States)

    Chrona, Eleni; Kostopanagiotou, Georgia; Damigos, Dimitrios; Batistaki, Chrysanthi


    Anterior cutaneous nerve entrapment syndrome (ACNES) is a commonly underdiagnosed and undertreated chronic state of pain. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the possible therapeutic strategies for the management of the syndrome. Seventeen studies about ACNES therapy were reviewed; of them, 15 were case–control studies, case series, or case reports, and two were randomized controlled trials. The presently available management strategies for ACNES include trigger point injections (diagnostic and therapeutic), ultrasound-guided blocks, chemical neurolysis, and surgical neurectomy, in combination with systemic medication, as well as some emerging techniques, such as radiofrequency ablation and neuromodulation. An increased awareness of the syndrome and the use of specific diagnostic criteria for its recognition are required to facilitate an early and successful management. This review compiles the proposed management strategies for ACNES. PMID:28144159

  16. Cutaneous Leishmaniasis – Dermoscopic Findings And Cryotherapy

    Directory of Open Access Journals (Sweden)

    Dobrev Hristo P.


    Full Text Available We present a 60-year-old male patient who, three months after a holiday in Southern Greece, found a small ‘pimple’ on his back, which gradually got as big as a small walnut, the central part becoming ulcerated and scabby. Dermatological examination found an erythematous-to-livid nodular lesion on the right shoulder; it was 16 mm in diameter with central ulceration, covered with brownish crust which discharged pus-like secretion upon pressure. Microscope examination of Romanowsky-Giemsa stained lesion material detected amastigote forms of Leishmania tropica. The culture investigation and serological tests for leishmaniasis were negative. Dermoscopy of the lesion found the following features: erythema, hyperkeratosis, central ulceration covered with brownish crust, “yellow tears-like” structures and “white starburst-like” patterns, and various vascular structures (including dotted vessels, comma-shaped vessels, hairpin- and glomerular-like vessels. The patient was diagnosed with cutaneous leishmaniasis and underwent four cryotherapy sessions every other week with excellent therapeutic results - complete resolution of infiltrate with subsequent gentle hypopigmented scarring. In conclusion, dermoscopy is an easily accessible non-invasive method which can be useful for the diagnosis of cutaneous leishmaniasis. Cryotherapy is the treatment of choice for single skin lesions.

  17. Molecular Bases of Cutaneous and Uveal Melanomas

    Directory of Open Access Journals (Sweden)

    Sudeep Gaudi


    Full Text Available Intensive research in recent years has begun to unlock the mysteries surrounding the molecular pathogenesis of melanoma, the deadliest of skin cancers. The high-penetrance, low-frequency susceptibility gene CDKN2A produces tumor suppressor proteins that function in concert with p53 and retinoblastoma protein to thwart melanomagenesis. Aberrant CDKN2A gene products have been implicated in a great many cases of familial cutaneous melanoma. Sporadic cases, on the other hand, often involve constitutive signal transduction along the mitogen-activated protein kinase (MAPK pathway, with particular focus falling upon mutated RAS and RAF protooncogenes. The proliferative effects of the MAPK pathway may be complemented by the antiapoptotic signals of the PI3K/AKT pathway. After skin, melanoma most commonly affects the eye. Data for the constitutive activation of the MAPK pathway in uveal melanoma exists as well, however, not through mutations of RAS and RAF. Rather, evidence implicates the proto-oncogene GNAQ. In the following discussion, we review the major molecular pathways implicated in both familial and sporadic cutaneous melanomagenesis, the former accounting for approximately 10% of cases. Additionally, we discuss the molecular pathways for which preliminary evidence suggests a role in uveal melanomagenesis.

  19. Approach to cutaneous lymphoid infiltrates: When to consider lymphoma?

    Directory of Open Access Journals (Sweden)

    Yann Vincent Charli-Joseph


    Full Text Available Cutaneous lymphoid infiltrates (CLIs are common in routine dermatopathology. However, differentiating a reactive CLI from a malignant lymphocytic infiltrate is often a significant challenge since many inflammatory dermatoses can clinically and/or histopathologically mimic cutaneous lymphomas, coined pseudolymphomas. We conducted a literature review from 1966 to July 1, 2015, at using the search terms: Cutaneous lymphoma, cutaneous pseudolymphoma, cutaneous lymphoid hyperplasia, simulants/mimics/imitators of cutaneous lymphomas, and cutaneous lymphoid infiltrates. The diagnostic approach to CLIs and the most common differential imitators of lymphoma is discussed herein based on six predominant morphologic and immunophenotypic, histopathologic patterns: (1 Superficial dermal T-cell infiltrates (2 superficial and deep dermal perivascular and/or nodular natural killer/T-cell infiltrates (3 pan-dermal diffuse T-cell infiltrates (4 panniculitic T-cell infiltrates (5 small cell predominant B-cell infiltrates, and (6 large-cell predominant B-cell infiltrates. Since no single histopathological feature is sufficient to discern between a benign and a malignant CLI, the overall balance of clinical, histopathological, immunophenotypic, and molecular features should be considered carefully to establish a diagnosis. Despite advances in ancillary studies such as immunohistochemistry and molecular clonality, these studies often display specificity and sensitivity limitations. Therefore, proper clinicopathological correlation still remains the gold standard for the precise diagnosis of CLIs.

  1. Adverse Cutaneous Reactions to Psychotropic Drugs: A Review

    Directory of Open Access Journals (Sweden)

    Filipa Novais


    Full Text Available Introduction: Psychotropic drugs are often implicated in cutaneous adverse drug reactions. While most of these reactions have a benign character, it is still important, however, to consider its role in the increasing stigma and treatment adherence. A small number of the cutaneous adverse drug reactions can develop into serious and potentially fatal conditions. Objectives: This article aims to review the most common cutaneous adverse drug reactions in patients taking psychotropic drugs. Methods: In this study, a search was carried out in the MEDLINE database for English language articles published , from 1999 to 2014, using as keywords: psychiatric, psychotropic, cutaneous, adverse reaction, antidepressive agents, antipsychotics, benzodiazepines, mood stabilizers, anticonvulsant, dementia. Information available from the Portuguese regulatory and supervising agency (Infarmed was also included.Results: 121 articles were found with reference to cutaneous adverse drug reactions associated with psychotropic drugs. The drugs most frequently reported as associated with such adverse effects were anticonvulsants used as mood stabilizers, followed by the antipsychotics . The antidementia drugs were rarely associated with serious cutaneous adverse reactions. Discussion and Conclusion: Cutaneous drug adverse reactions are common in psychiatric clinical practice and typically are minor in severity. The most severe reactions are most often associated with the use of mood stabilizing medications. Some of these side effects can be solved with reduction or drug discontinuation. More severe cases should be referred to a specialist in dermatology.

  2. Prevalence of Cutaneous Leishmaniasis in Ramshir, Iran; an Epidemiological Study

    Vazirianzadeh B.* PhD,


    Full Text Available Aims Cutaneous leishmaniasis is a prevalent parasitological disease with diverse clinical manifestations in Iran. Therefore, the present retrospective study carried out to describe the demographic features of cutaneous leishmaniasis in Ramshir, Iran. Materials & Methods This descriptive study was performed on 136 cutaneous leishmaniasis patients whose data were recorded in the Ramshir health center during 2006-9. Demographic information of patients including age, sex, habitat and sites of lesions, month and years of incidence were recorded. The data were analyzed by SPSS 16 software. Findings Totally 79 patients (58.1% resided in urban areas and the born to 9 years (49.3% was recognized as the most infected age group. Hands (41.2% had the highest rates of cutaneous leishmaniasis lesions followed by face (36.0% and foot (22.8%. The maximum number of cutaneous leishmaniasis lesions was reported in March. Conclusion As cutaneous leishmaniasis in Ramshir seemed to be an endemic rural type, the appropriate preventing measures regarding to the rural cutaneous leishmaniasis should be considered to decrease incidence of the disease in the region.

  3. Neurotrophic Modulation of Myelinated Cutaneous Innervation and Mechanical Sensory Loss in Diabetic Mice (United States)

    Christianson, Julie A.; Ryals, Janelle M.; Johnson, Megan S.; Dobrowsky, Rick T.; Wright, Douglas E.


    Human diabetic patients often lose touch and vibratory sensations, but to date, most studies on diabetes-induced sensory nerve degeneration have focused on epidermal C-fibers. Here, we explored the effects of diabetes on cutaneous myelinated fibers in relation to the behavioral responses to tactile stimuli from diabetic mice. Weekly behavioral testing began prior to STZ administration and continued until 8 weeks, at which time myelinated fiber innervation was examined in the footpad by immunohistochemistry using antiserum to NF-H and MBP. Diabetic mice developed reduced behavioral responses to non-noxious (monofilaments) and noxious (pin prick) stimuli. In addition, diabetic mice displayed a 50% reduction in NF-H-positive myelinated innervation of the dermal footpad compared to non-diabetic mice. To test whether two neurotrophins NGF and/or NT-3 known to support myelinated cutaneous fibers could influence myelinated innervation, diabetic mice were treated intrathecally for two weeks with NGF, NT-3, NGF and NT-3. Neurotrophin-treated mice were then compared to diabetic mice treated with insulin for two weeks. NGF and insulin treatment both increased paw withdrawal to mechanical stimulation in diabetic mice, whereas NT-3 or a combination of NGF and NT-3 failed to alter paw withdrawal responses. Surprisingly, all treatments significantly increased myelinated innervation compared to control-treated diabetic mice, demonstrating that myelinated cutaneous fibers damaged by hyperglycemia respond to intrathecal administration of neurotrophins. Moreover, NT-3 treatment increased epidermal Merkel cell numbers associated with nerve fibers, consistent with increased numbers of NT-3-responsive slowly adapting A-fibers. These studies suggest that myelinated fiber loss may contribute as significantly as unmyelinated epidermal loss in diabetic neuropathy, and the contradiction between neurotrophin-induced increases in dermal innervation and behavior emphasize the need for multiple

  4. Multiple cutaneous melanomas associated with gastric and brain metastases* (United States)

    Grander, Lara Caroline; Cabral, Fernanda; Lisboa, Alice Paixão; Vale, Gabrielle; Barcaui, Carlos Baptista; Maceira, Juan Manuel Pineiro


    The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronous primary cutaneous melanomas. We suggest the research on the mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) (INK4a) in such cases. We also emphasize the importance of clinical examination and dermoscopy of the entire tegument, even after a malignant melanocytic lesion is identified.

  5. A case of cutaneous paragonimiasis presented with minimal pleuritis. (United States)

    Singh, T Shantikumar; Devi, Kh Ranjana; Singh, S Rajen; Sugiyama, Hiromu


    Clinically, paragonimiasis is broadly classified into pulmonary, pleuropulmonary, and extrapulmonary forms. The common extrapulmonary forms are cerebral and cutaneous paragonimiasis. The cutaneous paragonimiasis is usually presented as a slowly migrating and painless subcutaneous nodule. The correct diagnosis is often difficult or delayed or remained undiagnosed until the nodule becomes enlarged and painful and the cause is investigated. We report here a case of cutaneous paragonimiasis in a male child who presented with mild respiratory symptoms. The diagnosis of paragonimiasis was based on a history of consumption of crabs, positive specific serological test, and blood eosinophilia. The swelling and respiratory symptoms subsided after a prescribed course of praziquantel therapy.

  6. Primary Cutaneous Chrysosporium Infection following Ear Piercing: A Case Report

    Directory of Open Access Journals (Sweden)

    Poonkiat Suchonwanit


    Full Text Available Chrysosporium is a large genus of saprophytic fungi that is commonly found in the soil. Infection caused by this organism is rare in humans and typically occurs in immunocompromised patients. Primary cutaneous Chrysosporium infection is relatively rare and has been reported in a heart transplant patient. The prognosis is usually favorable, but very poor in the setting of persistent profound immunosuppression. We herein report a case of primary cutaneous Chrysosporium infection following ear piercing in an immunocompetent patient. It is important for clinicians to consider this condition in patients with slow-onset skin and soft tissue infection following cutaneous injury, even in an immunocompetent setting.

  7. Acetylcholine released from cholinergic nerves contributes to cutaneous vasodilation during heat stress (United States)

    Shibasaki, Manabu; Wilson, Thad E.; Cui, Jian; Crandall, Craig G.


    Nitric oxide (NO) contributes to active cutaneous vasodilation during a heat stress in humans. Given that acetylcholine is released from cholinergic nerves during whole body heating, coupled with evidence that acetylcholine causes vasodilation via NO mechanisms, it is possible that release of acetylcholine in the dermal space contributes to cutaneous vasodilation during a heat stress. To test this hypothesis, in seven subjects skin blood flow (SkBF) and sweat rate were simultaneously monitored over three microdialysis membranes placed in the dermal space of dorsal forearm skin. One membrane was perfused with the acetylcholinesterase inhibitor neostigmine (10 microM), the second membrane was perfused with the NO synthase inhibitor N(G)-nitro-l-arginine methyl ester (l-NAME; 10 mM) dissolved in the aforementioned neostigmine solution (l-NAME(Neo)), and the third membrane was perfused with Ringer solution as a control site. Each subject was exposed to approximately 20 min of whole body heating via a water-perfused suit, which increased mean body temperature from 36.4 +/- 0.1 to 37.5 +/- 0.1 degrees C (P heat stress, SkBF at each site was normalized to its maximum value, identified by administration of 28 mM sodium nitroprusside. Mean body temperature threshold for cutaneous vasodilation was significantly lower at the neostigmine-treated site relative to the other sites (neostigmine: 36.6 +/- 0.1 degrees C, l-NAME(Neo): 37.1 +/- 0.1 degrees C, control: 36.9 +/- 0.1 degrees C), whereas no significant threshold difference was observed between the l-NAME(Neo)-treated and control sites. At the end of the heat stress, SkBF was not different between the neostigmine-treated and control sites, whereas SkBF at the l-NAME(Neo)-treated site was significantly lower than the other sites. These results suggest that acetylcholine released from cholinergic nerves is capable of modulating cutaneous vasodilation via NO synthase mechanisms early in the heat stress but not after

  8. Mycobacterium fortuitum cutaneous infection from amateur tattoo. (United States)

    Suvanasuthi, Saroj; Wongpraparut, Chanisada; Pattanaprichakul, Penvadee; Bunyaratavej, Sumanas


    A case of cutaneous Mycobacterium fortuitum infection after receiving an amateur tattoo is reported. A few days after tattooing, an otherwise healthy 25-year-old Thai male presented with multiple discrete erythematous papules confined to the tattoo area. He was initially treated with topical steroid and oral antihistamine without improvement. Skin biopsy was carried out, and the histopathology showed mixed cell granuloma with a foreign body reaction (tattoo color pigments). The acid-fast bacilli stain was positive. The tissue culture grew M. fortuitum two weeks later. He was treated with clarithromycin 1,000 mg/day and ciprofloxacin 1,000 mg/day for 10 months with complete response. From the clinical aspect, tattoo-associated rapidly growing mycobacterium infection might be difficult to differentiate from the pigment-based skin reactions. Skin biopsy for histopathology and tissue culture for Mycobacterium probably will be needed in arriving at the diagnosis.

  9. Anastrozole-induced subacute cutaneous lupus erythematosus. (United States)

    Fisher, Juliya; Patel, Mital; Miller, Michael; Burris, Katy


    Drug-induced subacute cutaneous lupus erythematosus (DI-SCLE) has been associated with numerous drugs, but there are limited reports of its association with aromatase inhibitor anastrozole. We report the case of a patient undergoing treatment with anastrozole for breast cancer who presented with clinical, serological, and histological evidence consistent with DI-SCLE. Her condition quickly began to improve after the use of anastrozole was discontinued and hydroxychloroquine therapy was initiated. Cases such as ours as well as several others that implicate antiestrogen drugs in association with DI-SCLE seem to be contradictory to studies looking at the usefulness of treating systemic lupus erythematosus (SLE) with antiestrogen therapy. Further research on this relationship is warranted.

    da Silva Santos, Claire; Attarha, Sanaz; Saini, Ravi Kanth; Boaventura, Viviane; Costa, Jackson; Khouri, Ricardo; Barral-Netto, Manoel; Brodskyn, Cláudia Ida; Souchelnytskyi, Serhiy


    In this study, we used proteomics and biological network analysis to evaluate the potential biological processes and components present in the identified proteins of biopsies from cutaneous leishmaniasis (CL) patients infected by Leishmania braziliensis in comparison with normal skin. We identified 59 proteins differently expressed in samples from infected and normal skin. Biological network analysis employing identified proteins showed the presence of networks that may be involved in the cell death mediated by cytotoxic T lymphocytes. After immunohistochemical analyses, the expression of caspase-9, caspase-3, and granzyme B was validated in the tissue and positively correlated with the lesion size in CL patients. In conclusion, this work identified differentially expressed proteins in the inflammatory site of CL, revealed enhanced expression of caspase-9, and highlighted mechanisms associated with the progression of tissue damage observed in lesions.

  11. The genomic landscape of cutaneous melanoma. (United States)

    Zhang, Tongwu; Dutton-Regester, Ken; Brown, Kevin M; Hayward, Nicholas K


    Somatic mutation analysis of melanoma has been performed at the single gene level extensively over the past several decades. This has provided considerable insight into the critical pathways controlling melanoma initiation and progression. During the last 5 yr, next-generation sequencing (NGS) has enabled even more comprehensive mutational screening at the level of multigene panels, exomes and genomes. These studies have uncovered many new and unexpected players in melanoma development. The recent landmark study from The Cancer Genome Atlas (TCGA) consortium describing the genomic architecture of 333 cutaneous melanomas provides the largest and broadest analysis to date on the somatic aberrations underlying melanoma genesis. It thus seems timely to review the mutational landscape of melanoma and highlight the key genes and cellular pathways that appear to drive this cancer.

    The leishmaniases are parasitic diseases that are transmitted to humans by infected female sandflies. Cutaneous leishmaniasis (CL) is one of 3 main forms of the disease. CL is the most common form of the disease and is endemic in many urban and rural parts of Iran and usually caused by two species of Leishmania: L. major and L. tropica. We report a case of unusual leishmaniasis with 25 lesions on exposed parts of the body and right eyelid involvement (ocular leishmaniasis). The patient was a 75-year-old male farmer referred to health care center in Aran va Bidgol city. The disease was diagnosed by direct smear, culture, and PCR from the lesions. PCR was positive for Leishmania major. PMID:28210511

    Rocha, N; Velho, G; Horta, M; Martins, A; Massa, A


    Familial amyloidotic polyneuropathy is an autosomal dominant amyloidosis, characterized by the systemic deposition of amyloid with a particular involvement of the peripheral nerves. The disease generally manifests as a severe sensory, motor and autonomic neuropathy. Cardiomyopathy, nephropathy, vitreous opacities and carpal tunnel syndrome may occur in a variable association with the neuropathy. Trophic dermatological lesions are frequent in the more advanced stages of the disease. We examined the skin of 142 patients. The cutaneous manifestations more frequently observed were: xerosis (81.6%), seborrheic dermatitis (21.8%), traumatic and burn lesions (19.7%), acne (18.3%), neurotrophic ulcers (14%) and onychomycosis (10.5%). Among the hepatic transplanted patients (31%), seborrheic dermatitis and acne were the most frequent diagnoses.

    Kalegowda Deepadarshan


    Full Text Available Background: Hypopigmented skin lesions is very common among people of all age groups. There are limited studies in India about evaluation of hypopigmented skin conditions. The aim of my study is to evaluate the different etiologies of cutaneous hypopigmentation. Aim: The present study was undertaken to find the relative incidence of the various disorders causing a hypopigmented lesion in a random sample of 200 cases and to study site, distribution and characteristics of the lesions. Methods: A random sample of 200 patients presenting with one or more hypopigmented lesions to the outpatient department of Dermatology, Venereology and Leprosy in KVG Medical College and Hospital, Sullia from December 2011 to January 2013 was studied. Detailed history including address and occupation with special reference to onset and duration, preceding skin conditions, exposure to chemicals, topical application and family history was taken. Various characteristics of the lesion like site, size, number, distribution, surface and sensation were studied. After this samples were taken for relevant investigations like complete hemogram, biopsy, slit skin smear, KOH mount and assessed for the causes of hypopigmented lesions. Results: In our study, most common cause with cutaneous hypopigmentation was pityriasis versicolor, seen in 52%, followed by post inflammatory hypopigmentation in 32%, pre vitiligo in 6.5%, Hansen’s disease, idiopathic guttate hypomelanosis, nevus anemicus each in 2%, Woronoff’s ring in 1.5% and miscellaneous conditions in 2% of the cases. Commonest age group affected was 21-30 years. Males (49% and females (51% were almost equally affected. Conclusion: The study concludes that various conditions comes under hypopigmentary disorders. More common in young adults. Most common scaly condition was pityriasis versicolor and non scaly condition was pre vitiligo. Proper counseling and ruling out Hansen’s disease is required to alleviate the patient

  15. Cutaneous necrotizing vasculitis. Relation to systemic disease. (United States)

    Lotti, T M; Comacchi, C; Ghersetich, I


    Cutaneous necrotizing vasculitis (CNV) is a complex multisystem disease generally involving the skin and mucous membranes, often accompanied by renal, gastrointestinal, pericardial, neurological, and articular signs and symptoms. CNV may be idiopatical or occur in association with a drug, infection, or underlying disease. CNV has been shown in patients with chronic infections (viral, bacterial, protozoa, helminthic), serum sickness, a variety of collagen vascular diseases (systemic lupus erythematous, Sjögren's syndrome, rheumatoid arthritis, Behçet's disease) hyperglobulinemic states, cryoglobulinemia, bowel bypass syndrome, ulcerative colitis, cystic fibrosis, primary biliary cirrhosis and HIV infection. Association with malignancies is not frequent. Lymphoproliferative disorders (Hodgkin's disease, mycosis fungoides, lymphosarcoma, adult T-cell leukemia, multiple mieloma) and solid tumors (lung cancer, colon carcinoma, renal, prostate, head and neck cancer and breast cancer) may be associated with CNV. Whenever possible, treatment is directed at the elimination of the cause. In other cases after adequate laboratory screening local and systemic therapy are recommended.

  16. Influence of microemulsions on cutaneous drug delivery

    DEFF Research Database (Denmark)

    Kreilgaard, Mads


    In attempt to increase cutaneous drug delivery, microemulsion vehicles have been more and more frequently employed over recent years. Microemulsion formulations have been shown to be superior for both transdermal and dermal delivery of particularly lipophilic compounds, but also hydrophilic...... compounds appear to benefit from application in microemulsions compared to conventional vehicles, like hydrogels, emulsions and liposomes. The favourable drug delivery properties of microemulsions appear to mainly be attributed to the excellent solubility properties. However, the vehicles may also act...... as penetration enhancers depending on the oil/surfactant constituents, which involves a risk of inducing local irritancy. The correlation between microemulsion structure/composition and drug delivery potential is not yet fully elucidated. However, a few studies have indicated that the internal structure...

    Wawrzycki, Bartłomiej; Pietrzak, Aldona; Chodorowska, Grażyna; Kanitakis, Jean


    Diffuse cutaneous mastocytosis is the rarest subtype of mastocytosis among those that affect children. A 7-month-old girl presented at birth dry and thickened skin. On the second day of life, tense blisters appeared on erythrodermic areas and during the next days spread over the face, trunk, and limbs. The skin was bright red, had a "peau d'orange" appearance, and was considerably thickened with numerous translucent and hemorrhagic blisters. A skin biopsy revealed massive infiltration of the dermis with mast cells, leading to the diagnosis of diffuse erythrodermic mastocytosis. Systemic corticosteroids were given along with antihistamines with good results. Despite the progresses in the understanding of pathogenesis, genetics, and diagnostic criteria of mastocytosis, clear and reliable prognostic markers are still lacking, especially in order to predict systemic involvement. not only in diffuse but also in the commoner forms of the disease.

  18. Posterior antebrachial cutaneous neuropathy. Case report. (United States)

    Chang, C W; Oh, S J


    Posterior antebrachial cutaneous (PABC) neuropathy is rare. Two original cases are reported here. In case 1, the neuropathy is probably due to a traction injury in a reduction operation for humeral fracture. In case 2, it is injured associately with an operation in taking a myocutaneous flap. On examination, both cases showed a decreased sensation to pin-prick over the PABC nerve territories and a positive Tinel's sign near the injured sites. Sensory nerve conduction study of the PABC nerves revealed a low amplitude of the compound nerve action potential (CNAP) and a slow sensory nerve conduction velocity (SNCV) in case 1, and absent CNAP in case 2. Our study showed the sensory nerve conduction test is useful in confirming PABC neuropathy.

    Full Text Available Background: Diabetes mellitus affects individuals of all ages and socioeconomic status. Skin is affected by the acute metabolic derangements as well as by chronic degenerative complications of diabetes. Aims: To evaluate the prevalence of skin manifestations in patients with diabetes mellitus. To analyze the prevalence and pattern of skin disorders among diabetic patients from this region of Western Himalayas. Materials and Methods: One hundred consecutive patients with the diagnosis of diabetes mellitus and having skin lesions, either attending the diabetic clinic or admitted in medical wards were included in this study. Results: The common skin disorders were: x0 erosis (44%, diabetic dermopathy (36%, skin tags (32%, cutaneous infections (31%, and seborrheic keratosis (30%. Conclusion: Skin is involved in diabetes quite often and the manifestations are numerous. High prevalence of xerosis in our diabetic population is perhaps due to cold and dry climatic conditions in the region for most of the time in the year.

    Pilar F-Eire


    Full Text Available Only a few published case of fibrous hamartoma of infancy (FHI have commented on the changes in the overlying skin. There are descriptions of individual cases with cutaneous hyperpigmentation, hypertrichosis and hyperhidrosis. It is interesting to describe our case because, to our knowledge, the altered pigmentation of the overlying skin, with hairs on the surface, and eccrine gland hyperplasia combined with abortive hair follicles has not been reported together in association with the FHI. We recommend that all the biopsies must be excisional including overlying skin, thus the epidermal and dermal adnexal changes can be assessed in the microscopic evaluation which could have relevant implications from clinical and embryological point of view.

  3. A rare cause of cutanous vasculitis: Anastrosole

    Directory of Open Access Journals (Sweden)

    Didem Arslan Tas


    Full Text Available Breast cancer is the most frequently diagnosed type of cancer and the foremost reason of the death of women from cancer. Hormone receptor positive breast cancer is the most frequent type of breast cancer. Anastrosole is one of the aromatase inhibitors which is indicated for early stage of hormone receptor positive breast cancer of postmenopausal women. A 67-year-old woman was refered to Rheumatology Department from Medical Oncology Department for skin rashes which have started 3 months ago. In her medical history, she was diagnosed as infiltrative ductal carcinoma grade-2 in the right breast. She had a modified radical mastectomy operation for the right breast and subsequently, anastrosole was started as her hormone receptor was found positive in histopathological examination. The drug was stopped after 5 years by her oncologist however she went on using the drug on her own demand. Three months before her referral, non-itchy, painless reddish rash was started on legs and arms. After careful physical and laboratory examination and histopathologic alevaluation, she was diagnosed as middle-vessel necrotising vasculitis. Anastrosole was stopped. Steroid and azathyoprine were started. On the fifth month of therapy, all skin lesions were resolved with postinflammatory hyperpigmentation. No additional problem was met. This case report is suggesting that, anastrosole which is a frequently preferred agent in recentyears, could also cause leucocytoclastic vasculits. Very rare cases with cutanous vasculitis were previously presented. This case report suggests that, during the management of patients under anastrosole therapy, cutanous vasculitis should be monitored carefully. [Cukurova Med J 2014; 39(2.000: 369-372

  5. [Tungiasis and cutaneous larva migrans: unpleasant travel souvenirs]. (United States)

    Feldmeier, Hermann


    Tungiasis (sand flea disease) and cutaneous larva migrans (creeping eruption) are parasitic skin diseases in which the infectious agents only temporarily invade human skin. The parasites die in situ and eventually are eliminated by tissue repair mechanisms. Both diseases are zoonoses. Humans only accidentally become a host for animal hookworm larvae (resulting in cutaneous larva migrans), but get infected with Tunga penetrans as frequent as domestic animals. In travelers to tropical and subtropical regions tungiasis and cutaneous larva migrans are the most common imported skin diseases. The diagnosis is made clinically. In tungiasis the clinical manifestations depend on the stage of the disease. Intense local inflammation and bacterial superinfection are common. Cutaneous larva migrans is treated orally with ivermectin or albendazole. A repellent based on coconut oil effectively prevents penetration of sand fleas.

    The purpose of this study was to determine the frequency and nature of cutaneous alterations associated with PIDs. This article is a cross-sectional study at the department of allergy and clinical immunology of children’s medical center conducted between December 5, 2001 and April 20, 2002. The subjects included pediatric patients with a diagnosis of PID and dermatological diagnoses were made by a dermatologist. Two hundred and ten patients were studied They consisted of 68 cases of humoral deficiency, 22 cases of cellular and combined deficiencies, 57 cases of phagocytic defects and 63 cases of other PIDs. In 67 cases (31.8% the cutaneous alterations preceded and were the basis for clinical immunological diagnosis. Overall cutaneous alterations were infections in 99 cases and eczematous dermatitis in 27 cases. Our findings support the results of other studies that most PIDs have cutaneous features which being their typical aspects are highly suggestive for the diagnosis of PIDs.

  10. Evaluation through in vivo reflectance confocal microscopy of the cutaneous neurogenic inflammatory reaction induced by capsaicin in human subjects (United States)

    Căruntu, Constantin; Boda, Daniel


    We perform an in vivo analysis of the effects of capsaicin on cutaneous microvascularization. A total of 29 healthy subjects are administered a solution of capsaicin (CAP group) or a vehicle solution (nonCAP group) on the dorsal side of the nondominant hand. The evaluation is performed using in vivo reflectance confocal microscopy (RCM). Ten minutes after administration, the area of the section, the perimeter, and the Feret's diameter of the capillaries in the dermal papillae become significantly larger in the CAP group as against the nonCAP group, and this difference is maintained until the conclusion of the experiment. In vivo RCM allows the investigation of cutaneous vascular reactions induced by capsaicin. As such, this method may constitute an useful technique both for research and clinical practice.

    The durability of immune responses to smallpox vaccine is a subject of considerable debate. We compared cutaneous vaccinia responses in patients vaccinated in the distant past with vaccine-naïve individuals using serial close-up photographs. The previously vaccinated group had a significantly reduced time course and milder cutaneous reactions. Vaccinated individuals appear to maintain clinically detectable immunity against vaccinia for at least 20 years after smallpox vaccination.

    Cutaneous leishmaniasis affects millions of people around the world. Several species of Leishmania infect mouse strains, and murine models closely reproduce the cutaneous lesions caused by the parasite in humans. Mouse models have enabled studies on the pathogenesis and effector mechanisms of host resistance to infection. Here, we review the role of nitric oxide (NO), reactive oxygen species (ROS), and peroxynitrite (ONOO−) in the control of parasites by macrophages, which are both the host c...

    Cutaneous metastases arising from an internal malignancy are a rare phenomenon, occurring in 0.001% of all skin biopsies performed. Of these, 6.5% originate from the a primary colon cancer. Colon cancer, when metastatic to the skin, typically appears as a painless flesh-colored nodule or as a mass with occasional ulceration. We report a case of a large cutaneous metastasis to the suprascapular region as the initial presenting symptom of an underlying colon cancer.

  17. Specific cutaneous manifestations of internal malignancy. (United States)

    Kaplan, R P


    In summary, carcinoma is the most frequent cancer that metastasizes to the skin; lung cancer in men and breast cancer in women. Clinically distinctive patterns of cutaneous metastasis of epithelial origin include alopecia neoplastica, pulsatile nodules, Sister Mary Joseph's nodules, morpheaform, and cellulitis-like lesions. Biopsying these lesions reveals adenocarcinoma, squamous cell carcinoma, or anaplastic carcinoma. The type of histologic pattern seen can be a clue to the organ of origin giving rise to the cutaneous metastasis. Skin that is damaged allows for circulating malignant cells, often of epithelial or leukemic origin, to lodge and proliferate locally (inflammatory oncotaxis). The commonest form of leukemia to affect the skin of elderly males is chronic lymphocytic leukemia. However, when leukemia involves the mucous membranes, acute myeloid leukemia (acute monocytic and acute myelomonocytic leukemia) is the most likely diagnosis. When papules, nodules, or plaques develop on the head, neck, or torso in a middle-aged male accompanied by lymphadenopathy, there must be a high index of suspicion that these lesions are metastatic lymphomatous deposits. Definitive histologic diagnosis on a skin biopsy specimen is difficult. In this situation, it is best to rely on histologic patterns seen in lymphoid tissue along with cellular marker studies. An elderly patient having bone pain, anemia, elevated blood calcium level, and renal failure along with purplish or skin-colored nodules and plaques on the trunk has a good chance of having multiple myeloma. Biopsying these lesions is most certain to reveal atypical plasma cells, and blood immunoelectrophoresis will demonstrate characteristic monoclonal gammopathy. There are two malignancies seen in children under 3 years of age that often times affect the skin in a characteristic fashion. Letterer-Siwe disease, which is distinguished from other histocytic disorders by its cell of origin, the Langerhans cell, clinically

  18. Exogenous Tryptophan Promotes Cutaneous Wound Healing of Chronically Stressed Mice through Inhibition of TNF-α and IDO Activation.

    Directory of Open Access Journals (Sweden)

    Luana Graziella Bandeira

    Full Text Available Stress prolongs the inflammatory response compromising the dermal reconstruction and wound closure. Acute stress-induced inflammation increases indoleamine 2, 3-dioxygenase-stimulated tryptophan catabolism. To investigate the role of indoleamine 2, 3-dioxygenase expression and tryptophan administration in adverse effects of stress on cutaneous wound healing, mice were submitted to chronic restraint stress and treated with tryptophan daily until euthanasia. Excisional lesions were created on each mouse and 5 or 7 days later, the lesions were analyzed. In addition, murine skin fibroblasts were exposed to elevated epinephrine levels plus tryptophan, and fibroblast activity was evaluated. Tryptophan administration reversed the reduction of the plasma tryptophan levels and the increase in the plasma normetanephrine levels induced by stress 5 and 7 days after wounding. Five days after wounding, stress-induced increase in the protein levels of tumor necrosis factor-α and indoleamine 2, 3-dioxygenase, and this was inhibited by tryptophan. Stress-induced increase in the lipid peroxidation and the amount of the neutrophils, macrophages and T cells number was reversed by tryptophan 5 days after wounding. Tryptophan administration inhibited the reduction of myofibroblast density, collagen deposition, re-epithelialization and wound contraction induced by stress 5 days after wounding. In dermal fibroblast culture, the tryptophan administration increased the cell migration and AKT phosphorylation in cells treated with high epinephrine levels. In conclusion, tryptophan-induced reduction of inflammatory response and indoleamine 2, 3-dioxygenase expression may have accelerated cutaneous wound healing of chronically stressed mice.

    Kołodziejczyk, Beata; Gazda, Agnieszka; Hernik, Elżbieta; Szczygielska, Izabela; Rutkowska-Sak, Lidia; Koprowska, Marta Legatowicz


    Girl, aged 4 years old, began the disease with pain of the lower extremities, fever up to 38°C and signs of upper airway infection. Then the patient developed oedema and redness of the whole face, thickened skin, subcutaneous nodular foldings of the frontal, occipital, cervical and axillary regions, extensor areas of the joints; fine, hard whitish nodules in the frontal region and over interphalangeal joints of the hands, pruritus; oedemas of the ankles, knees and joints of the hands, cervical lymphadenopathy and hepatomegaly. Blood tests at the moment of the diagnosis revealed elevation of markers of inflammation as ESR and CRP, leukocytosis, thrombocytosis, hypoalbuminemia, and hyper-alfa-2-globulinemia. Histopathological examination of the skin biopsy specimen and subcutaneous tissue revealed myxoid subcutaneous tissue located under the dermis and a section consisting of myxoid mesenchymal tissue with inflammatory infiltration by histiocytic cells. The presence of acid mucopolysaccharides in fields of the myxoid tissue was also observed. The self-healing juvenile cutaneous mucinosis (SJCM) was diagnosed.

  20. Cutaneous Leishmaniasis in North Africa: a review

    Directory of Open Access Journals (Sweden)


    Full Text Available In North African countries, cutaneous leishmaniasis transmission has been increasing since the 1980s, with a significant increase in the incidence of cases and a spread of the geographical distribution. The disease currently represents a major public health problem with a productivity gap and an impediment for development, which results in dramatic socioeconomic and psycho-sanitary impacts. The incidence is more than thousands of cases every year in Algeria, Libya, Morocco, and Tunisia. In Egypt, only a few dozen cases per year are reported, mainly in the Sinai Peninsula. Three Leishmania species, associated with distinct eco-epidemiological and clinical patterns, are involved, namely Leishmania infantum, L. major, and L. tropica. However, L. major is by far the most frequent in Algeria, Libya, and Tunisia, with more than 90% of the registered cases. It is mainly encountered in rural areas under semi-arid, arid and Saharan climates. Leishmania tropica is more prevalent in Morocco, reaching 30–40% of isolates in some districts. Much data is still missing concerning the risk factors of the infection and the lesion development, as well as vector and reservoir ecology and behavior. The knowledge of such parameters, following multidisciplinary and integrated approaches, is crucial for better management and control of the disease, that also faces a lack of resources and efficient control measures.

  1. Mechanosensory neurons, cutaneous mechanoreceptors, and putative mechanoproteins. (United States)

    Del Valle, M E; Cobo, T; Cobo, J L; Vega, J A


    The mammalian skin has developed sensory structures (mechanoreceptors) that are responsible for different modalities of mechanosensitivity like touch, vibration, and pressure sensation. These specialized sensory organs are anatomically and functionally connected to a special subset of sensory neurons called mechanosensory neurons, which electrophysiologically correspond with Aβ fibers. Although mechanosensory neurons and cutaneous mechanoreceptors are rather well known, the biology of the sense of touch still remains poorly understood. Basically, the process of mechanosensitivity requires the conversion of a mechanical stimulus into an electrical signal through the activation of ion channels that gate in response to mechanical stimuli. These ion channels belong primarily to the family of the degenerin/epithelium sodium channels, especially the subfamily acid-sensing ion channels, and to the family of transient receptor potential channels. This review compiles the current knowledge on the occurrence of putative mechanoproteins in mechanosensory neurons and mechanoreceptors, as well as the involvement of these proteins on the biology of touch. Furthermore, we include a section about what the knock-out mice for mechanoproteins are teaching us. Finally, the possibilities for mechanotransduction in mechanoreceptors, and the common involvement of the ion channels, extracellular membrane, and cytoskeleton, are revisited.

  2. [NMF and cosmetology of cutaneous hydration]. (United States)

    Marty, J-P


    In the stratum corneum, the water binds to the intracellular hygroscopic and hydrosoluble substances called "natural moisturizing factors" or NMF. These "natural moisturizing factors" contained in the corneocytes are formed during epidermal differentiation and may represent up to 10 p. cent of the corneocyte mass. They are principally amino acids, carboxylic pyrrolidone acid, lactic acid, urea, glucose and mineral ions. Keratinization plays an important part in the formation of NMF that exhibit strong osmotic potential attracting the water molecules. The binding of water to NMF is the static aspect of cutaneous hydration. The second, dynamic, aspect is related to the selective permeability of the stratum corneum and to its lipid barrier properties, the permeability of which depends on the integrity and nature of the inter-corneocyte lipids and their lamellar organization between the cells. In these conditions, hydration cosmetics rely on two concepts that can be isolated or associated: the supply of hydrophilic substances to the stratum corneum, capable of attracting and retaining water (moisturizer) or capable of restoring the barrier in order to restore normal water loss or of protecting it against aggression (occlusive).

  3. Polymyxin B-Induced Diffuse Cutaneous Hyperpigmentation. (United States)

    Lahiry, Sandeep; Choudhury, Shouvik; Mukherjee, Ayan; Bhunya, Prajesh Kiran; Bala, Moumita


    Polymyxin B is a polypeptide-antibiotic, primarily used for resistant Gram-negative infections, first obtained from bacterium Bacillus polymyxa in the late 1940s. Antibiotic spectrum are restricted to mainly gram negative bacterias like Enterobacter, E. coli, Klebsiella, Salmonella, Pasteurella, Bordetella, Shigella; and particularly organisms like Pseudomonas aeruginosa and Acinetobacter baumannii, which are extremely potent to acquire antibiotic resistance. Side effects include neurotoxicity and acute renal tubular necrosis. Here, we present a rare case of skin hyper-pigmentation in a 65-year-old elderly male of Indian origin, diagnosed as a case of Multi-Drug Resistant (MDR) Klebsiella pneumonia, treated with intravenous antibiotics. The manifestations were observed after 4 days of Polymyxin B therapy initiation. All other concomitant drugs, infections, or immunologic disorders that, could have caused this symptom, were carefully excluded. An objective causality assessment reveals that, the cutaneous hyperpigmentation was possibly associated with Polymyxin B therapy, though further studies may be needed to explain the underlying mechanism.

    Davuodi, Setareh; Manshadi, Seyed Ali Dehghan; Salehi, Mohammad Reza; Yazdi, Farhad; Khazravi, Mona; Fazli, Jafar Taghizade


    Mucormycosis is an uncommon opportunistic infection that is caused by Mucorales from the Zygomycetes class. Patients with severe immunodeficiency admitted to the hospital are at greatest risk for developing this infection. Mucormycosis usually is transmitted in humans by inhalation or inoculation of spores in the skin or mucous membranes. A 66-year-old man developed a surgical wound infection at 1 week after kidney transplant that did not improve despite broad-spectrum antibiotics and debridement. He was transferred to our hospital 45 days after transplant and had fever and a large purulent wound that was surrounded by a black necrotizing margin. Immunosuppressive drugs were discontinued and the dosage of prednisolone was decreased. Massive debridement was performed but was incomplete because he had full-thickness abdominal wall necrosis. Histopathology showed broad fungal hyphae without septation, consistent with the diagnosis of mucormycosis. Despite antifungal therapy with amphotericin B and additional debridement, the patient died of septic shock at 52 days after kidney transplant. Cutaneous fungal infections should be considered in the differential diagnosis of any nonhealing infected wound that does not respond to broad-spectrum antibiotics, especially in patients with predisposing risk factors such as transplant.

  5. Comorbidity of Leishmania major with cutaneous sarcoidosis

    Directory of Open Access Journals (Sweden)

    Hamideh Moravvej


    Full Text Available Background: leishmaniasis infection might manifest as sarcoidosis; on the other hand, some evidences propose an association between sarcoidosis and leishmaniasis. Most of the times, it is impossible to discriminate idiopathic sarcoidosis from leishmaniasis by conventional histopathologic exam. Aim: We performed a cross-sectional study to examine the association of sarcoidosis with leishmaniasis in histopathologically diagnosed sarcoidal granuloma biopsy samples by polymerase chain reaction (PCR. Materials and Methods: We examined paraffin-embedded skin biopsy samples obtained from patients with clinical and histopathological diagnosis as naked sarcoidal granuloma, referred to Skin Research Center of Shaheed Beheshti Medical University from January 2001 to March 2010, in order to isolate Leishmania parasite. The samples were reassessed by an independent dermatopathologist. DNA extracted from all specimens was analyzed by the commercially available PCR kits (DNPTM Kit, CinnaGen, Tehran, Iran to detect endemic Leishmania species, namely leishmania major (L. major. Results: L. major was positive in PCR of Eight out of twenty-five examined samples. Conclusion: Cutaneous leishmaniasis may be misinterpreted as sarcoidosis; in endemic areas, when conventional methods fail to detect Leishmania parasite, PCR should be utilized in any granulomatous skin disease compatible with sarcoidosis, regardless of the clinical presentation or histopathological interpretation.

  6. Epidemiological aspects of cutaneous malignant melanoma (review). (United States)

    Serraino, D; Fratino, L; Gianni, W; Campisi, C; Pietropaolo, M; Trimarco, G; Marigliano, V


    There is an increasing interest in the etiology of cutaneous malignant melanoma (CMM). Once considered a rare tumour, CMM is now the fourth commonest cancer in Australia and New Zeland, the tenth in the Usa, Canada and Scandinavia and the eighteenth in Great Britain. The growing scientific concern on the urgent need to highlight the cause/s of CMM is well documented by the large number of well-designed and well-conducted epidemiological studies reported in the last two decades. Such studies facilitated testing of many etiological hypotheses derived from earlier descriptive investigations and contributed to significant progress in understanding the etiology of such disease. The quantification of the extent to which the increases in CMM incidence and mortality rates are related to new lifestyles and to new patterns of exposure to potential carcinogenetic agents is essential in order to establish an appropriate preventive strategy. In population of mainly European origin a substantial proportion of the increased incidence of CMM is attributable to steady change from predominantly occupational to predominantly recreational exposure to solar radiation. Therefore the present review puts particular emphasis on exposure to sunlight as well as to artificial ultraviolet light, as modifiable causes of CMM. Incidence and mortality data and other potential risk factors for the development of CMM will also be briefly reviewed.

  7. Cutaneous reactions due to antihypertensive drugs

    Directory of Open Access Journals (Sweden)

    Upadhayai J


    Full Text Available Out of a total of 1147 patients on antihypertensive drugs, 23 (2.04% developed adverse cutaneous drug reactions (ACDR. The commonest antihypertensive drug group causing ACDR was beta-blockers of which atenolol was the commonest culprit. The second most common group was calcium channel blockers with amlodipine as the commonest offender. The most common patterns of ACDR observed included urticaria followed by lichenoid drug eruption (LDE. We noted 2 new patterns of reactions; (i one patient developed brownish blue pigmentation of nails while on atenolol for 3 years, which resolved in 4 months after withdrawal and (ii another patient on amlodipine for 8 years developed Schamberg′s like purpuric pigmentation, which resolved on withdrawal of drug within 3 months. These findings have not been reported in the literature earlier. This study is presented for paucity of Indian data on ACDR due to antihypertensive drugs, and remarkable advancement in area of cardiovascular and antihypertensive pharmacology and a large number of population taking antihypertensive drugs.

  8. Differentiation in cutaneous adnexal tumors: Immunohistochemical study

    Directory of Open Access Journals (Sweden)

    Figen BARUT


    Full Text Available Cutaneous adnexal neoplasms are rare tumors that display differentiation in different ways. The aim of this study is, to present embryonic developmental properties and to determine the way of differentiation of adnexal neoplasms by evaluating the immunohistochemical expression of various markers.Forty-seven cases with adnexal tumors enrolled in this study. Histopathologic groups of these 47 cases were: 15 (32% hair follicle tumors, 11 (23.4% sebaceous tumors, 8 (17% apocrine tumors, and 13 (27.6% eccrine tumors. CK5-6, CK6, CK7, CK8, CK10, CK19, GCDFP-15, carcinoembryonic antigen, epithelial membrane antigen and S100 protein expressions were examined by immunohistochemical methods.As a result of this immunohistochemical study it was concluded that the expression of CK5-6 and CK8 carries more importance than other markers in determining certain types of differentiation of hair follicle tumors. It was also determined that, epithelial membrane antigen expression is important for the diagnosis of sebaceous tumors and the markers like CK8, CK10 and carcinoembryonic antigen may aid for the same purpose as well. It was found that, GCDFP-15 as well as CK5-6 expressions are significant for apocrine tumors, and carcinoembryonic antigen reaction as well as CK8 positivity will aid in determining differentiation of eccrine tumors. The presence of similar CK6 expression in all kinds of adnexal tumors has demonstrated that this marker is useless in differential diagnosis.

  9. Agraphesthesia. A disorder of directional cutaneous kinesthesia or a disorientation in cutaneous space. (United States)

    Bender, M B; Stacy, C; Cohen, J


    Tests for graphesthesia and for directional cutaneous kinesthesia (DCK) were performed on a large series of neurological patients and normal subjects, in addition to the standard tests for discriminative sensation. Defects in graphesthesia and DCK were found with lesions at all levels of the nervous system. Graphesthesia was more often and more severely affected than DCK. These functions when impaired were always associated with other sensory defects (directional joint kinesthesia, two-point discrimination, etc.) in different combinations. It appears DCK is probably the basis for graphesthesia. Recent experimental studies have provided an anatomic and physiologic basis for DCK and for graphesthesia. These studies have also discredited wide-held beliefs on the transmission of discriminative sensation through the spinal cord. In this light, the history of ideas about sensation and its mediation is reviewed, and it is concluded that DCK alone deserves to be called a "posterior column function". Graphesthesia and DCK are discussed as kinesthetic functions implying orientation in cutaneous sensory space. These are compared to stereognosis and braille reading, which are complex derived functions depending also on motion, but directed towards recognition in external haptic space. Graphesthesia and DCK should both be considered as distinct forms of somatic sensibility which are valuable adjuncts to the clinical sensory examination.

  10. IL-33 accelerates cutaneous wound healing involved in upregulation of alternatively activated macrophages. (United States)

    Yin, Hui; Li, Xiangyong; Hu, Shilian; Liu, Tao; Yuan, Baohong; Gu, Hongbiao; Ni, Qian; Zhang, Xiaofan; Zheng, Fang


    IL-33 is a recently recognized member of the IL-1 family and has been best identified as a potent inducer of Th2-type immune responses. Increasing evidence, however, indicates that IL-33 also represents an important mediator of mucosal healing and epithelial restoration and repair. In this study, we further explore the potential effect of IL-33 in cutaneous wound healing. A full-thickness skin wound was generated on the back of mice and treated with IL-33 or vehicle intraperitoneally. Our results revealed that the levels of IL-33 mRNA and protein were significantly enhanced in incisional wound skin. Meantime, administration of IL-33 obviously accelerated wound healing with wounds gaping narrower and exhibiting enhanced reepithelialization. IL-33 upregulation also promoted the collagen deposition and the expression of extracellular matrix (ECM)-associated genes such as fibronectin and collagen IIIa, which implies a direct effect of IL-33 on matrix synthesis. Furthermore, IL-33 facilitated the development of alternatively activated macrophages (AAM) in incisional wound tissue, which closely related to resolution of inflammation and promotion of wound repair. Taken together, these findings suggest that IL-33 may play a pivotal role in maintenance of cutaneous homeostasis and acceleration of normal wound healing.

  11. Reactivation of cutaneous and mucocutaneous tegumentary leishmaniasis in rheumatoid arthritis patients: an emerging problem?

    Directory of Open Access Journals (Sweden)

    Regina Maia de Souza

    Full Text Available ABSTRACT Rheumatoid arthritis (RA is a chronic condition that is frequent in patients living in tropical areas exposed to leishmaniasis. RA therapy involves immunosuppressant drugs such as methotrexate (MTX, monoclonal antibodies (mAbs and prednisone. We report an unusual presentation of cutaneous (CL or mucocutaneous leishmaniasis (ML in RA patients from an endemic area of leishmaniasis. A 51-year-old woman noted a cutaneous ulcer on her left ankle during MTX and prednisone RA therapy. Initially diagnosed as a venous stasis ulcer, the aspirate of the injury revealed the presence of Leishmania DNA. A 73-year-old woman presenting non-ulcerated, infiltrated and painful erythematous nodules inside her nostrils while receiving MTX, anti-TNF mAb, and prednisone for RA, had also the aspirate of injuries showing the presence of Leishmania DNA. Both patients healed after the therapy with liposomal amphotericin. The RA therapy has changed to low-dose prednisone, without further reactivation episodes. Both cases suggest that CL or ML can reactivate after administration of an immunosuppressant for RA treatment. Therefore, immunosuppressive treatments for RA should be carefully prescribed in patients from endemic areas or with a history of CL and ML.

  12. Cutaneous manifestations in renal failure patients: A case series

    Directory of Open Access Journals (Sweden)

    Banerjee S


    Full Text Available Cutaneous involvement in renal disease is due to a host of factors ranging from metabolic disturbances to immunosuppressive drugs. Herein we report a series of six cases of renal failure with varied cutaneous manifestations ranging from infections to neoplasms due to prolonged immunosuppression. Our first case had cutaneous cryptococcosis where skin lesions gave a clue to the diagnosis of altered sensorium and underlying meningitis. The second case initially presented with florid warts and was treated successfully but later presented with an explosive recurrence of skin lesions due to malignant transformation. Our third case had basal cell carcinoma over the presternal region that was successfully treated with liquid nitrogen cryotherapy. Our fourth case had diabetic nephropathy that presented with septicemia and purpura fulminans. The last case had cutaneous manifestations of drug therapy because of heparin infusion. To conclude, cutaneous manifestations in patients with renal failure are varied and a high degree of suspicion is needed for early diagnosis and aggressive treatment to effectively combat mortality and morbidity.

  13. The presentation, pathology, and current management strategies of cutaneous metastasis

    Directory of Open Access Journals (Sweden)

    Christina Yin Bin Wong


    Full Text Available Skin metastases are rare in the routine clinical practice of dermatology, but are of major clinical significance because they usually indicate advanced disease. We reviewed the literature on skin metastasis regarding recent trends in clinical presentation and diagnosis of the most common cutaneous lesions. An extensive literature review was conducted using PubMed from May 26, 2011 to July 16, 2013 relating cutaneous metastases. Articles chosen for reference were queried with the following prompts: "Cutaneous metastases", "clinical presentation", "histological features", and "immunohistochemistry". Further searches included "treatment" and "management" options for "metastatic breast", "metastatic colorectal", "metastatic melanoma", "metastatic lung", and "hematologic cancers." We also reviewed the literature on the current management of melanoma as a model for all cutaneous metastatic disease. Our own clinical findings are presented and compared to the literature. Additionally, we highlight the most useful immunohistochemical studies that aid in diagnoses. Several novel therapies and combination therapies such as electrochemotherapy, vemurafenib, and imiquimod will be discussed for palliative treatment of cancers that have been found to improve cutaneous lesions. We review these notable findings and developments regarding skin metastases for the general dermatologist.

  14. Eight cases of feline cutaneous leishmaniasis in Texas. (United States)

    Trainor, K E; Porter, B F; Logan, K S; Hoffman, R J; Snowden, K F


    Leishmaniasis is a zoonotic disease caused by intracellular Leishmania protozoa that are transmitted by sandflies. The disease occurs in 3 forms: cutaneous, mucocutaneous, and visceral. Cutaneous leishmaniasis has been reported in cats in Europe and South America and in 1 cat from Texas. Leishmania mexicana is endemic in Texas and has been reported to cause cutaneous lesions in humans. This article describes the pathology of 8 biopsy cases of feline cutaneous leishmaniasis presented to the Texas Veterinary Medical Diagnostic Laboratory over a 3.5-year period. The median age of the cats was 3 years; each was presented with nodular, ulcerative lesions on the pinnae and less commonly on the muzzle and periorbital skin. Histologically, the lesions were nodular to diffuse histiocytic dermatitis with numerous amastigotes (2-4 μm) within macrophages and occasionally within the interstitium. Organisms were often contained within round, clear, intracellular vacuoles. In areas of necrosis, organisms were also free within the interstitium. The overlying epidermis was hyperkeratotic, hyperplastic, and often ulcerated. The organisms were not argyrophilic (Gomori methenamine silver), reacted poorly with periodic acid-Schiff reagent, and were inconsistently basophilic with Giemsa. Although not readily visible histologically, kinetoplasts were evident in amastigotes in cytologic preparations. The lesions were similar to those described for cutaneous L. mexicana infection in humans. In 5 of the 8 cats, Leishmania mexicana DNA was amplified from paraffin-embedded tissue by polymerase chain reaction and sequenced.

  15. Photodynamic therapy for multi-resistant cutaneous Langerhans cell histiocytosis

    Directory of Open Access Journals (Sweden)

    Arjen F. Nikkels


    Full Text Available Langerhans cell histiocytosis is a rare group of proliferative disorders. Beside cutaneous involvement, other internal organs can be affected. The treatment of cutaneous lesions is difficult and relies on topical corticosteroids, carmustine, nitrogen mustard, and photochemotherapy. Systemic steroids and vinblastine are used for recalcitrant skin lesions. However, some cases fail to respond. An 18-month old boy presented a CD1a+, S100a+ Langerhans cell histocytosis with cutaneous and severe scalp involvement. Topical corticosteroids and nitrogen mustard failed to improve the skin lesions. Systemic corticosteroids and vinblastine improved the truncal involvement but had no effect on the scalp lesions. Methyl-aminolevulinate (MAL based photodynamic therapy (PDT resulted in a significant regression of the scalp lesions. Control histology revealed an almost complete clearance of the tumor infiltrate. Clinical follow-up after six months showed no recurrence. Although spontaneous regression of cutaneous Langerhans cell histiocytosis is observed, the rapid effect of photodynamic therapy after several failures of other treatment suggests that photodynamic therapy was successful. As far as we know this is the first report of photodynamic therapy for refractory skin lesions. Larger series are needed to determine whether photodynamic therapy deserves a place in the treatment of multiresistant cutaneous Langerhans cell histiocytosis.

  16. The Role of Iron in the Skin & Cutaneous Wound Healing

    Directory of Open Access Journals (Sweden)

    Josephine Anne Wright


    Full Text Available In this review article we discuss current knowledge about iron in the skin and the cutaneous wound healing process. Iron plays a key role in both oxidative stress and photo-induced skin damage. The main causes of oxidative stress in the skin include reactive oxygen species (ROS generated in the skin by ultraviolet (UVA 320-400 nm portion of the ultraviolet spectrum and biologically available iron. We also discuss the relationships between iron deficiency, anaemia and cutaneous wound healing. Studies looking at this fall into two distinct groups. Early studies investigated the effect of anaemia on wound healing using a variety of experimental methodology to establish anaemia or iron deficiency and focused on wound-strength rather than effect on macroscopic healing or re-epithelialisation. More recent animal studies have investigated novel treatments aimed at correcting the effects of systemic iron deficiency and localised iron overload. Iron overload is associated with local cutaneous iron deposition, which has numerous deleterious effects in chronic venous disease and hereditary haemochromatosis. Iron plays a key role in chronic ulceration and conditions such as Rheumatoid Arthritis (RA and Lupus Erythematosus are associated with both anaemia of chronic disease and dysregulation of local cutaneous iron haemostasis. Iron is a potential therapeutic target in the skin by application of topical iron chelators and novel pharmacological agents, and in delayed cutaneous wound healing by treatment of iron deficiency or underlying systemic inflammation.

  17. Exosomes derived from human adipose mensenchymal stem cells accelerates cutaneous wound healing via optimizing the characteristics of fibroblasts (United States)

    Hu, Li; Wang, Juan; Zhou, Xin; Xiong, Zehuan; Zhao, Jiajia; Yu, Ran; Huang, Fang; Zhang, Handong; Chen, Lili


    Prolonged healing and scar formation are two major challenges in the treatment of soft tissue trauma. Adipose mesenchymal stem cells (ASCs) play an important role in tissue regeneration, and recent studies have suggested that exosomes secreted by stem cells may contribute to paracrine signaling. In this study, we investigated the roles of ASCs-derived exosomes (ASCs-Exos) in cutaneous wound healing. We found that ASCs-Exos could be taken up and internalized by fibroblasts to stimulate cell migration, proliferation and collagen synthesis in a dose-dependent manner, with increased genes expression of N-cadherin, cyclin-1, PCNA and collagen I, III. In vivo tracing experiments demonstrated that ASCs-Exos can be recruited to soft tissue wound area in a mouse skin incision model and significantly accelerated cutaneous wound healing. Histological analysis showed increased collagen I and III production by systemic administration of exosomes in the early stage of wound healing, while in the late stage, exosomes might inhibit collagen expression to reduce scar formation. Collectively, our findings indicate that ASCs-Exos can facilitate cutaneous wound healing via optimizing the characteristics of fibroblasts. Our results provide a new perspective and therapeutic strategy for the use of ASCs-Exos in soft tissue repair. PMID:27615560

  18. [Osteo-cutaneous Mycobacterium marinum infection of the elbow and reconstruction with radial collateral artery perforator-based propeller flap]. (United States)

    Gabert, P-E; Lievain, L; Vallée, A; Joly, P; Auquit Auckbur, I


    Mycobacterium marinum is an atypical and non-tuberculosis mycobacterium that mainly leads to cutaneous infections. Infections occur through inoculation of the organism through injury to the skin in the presence of contaminated water or fish. The patient often presents with unspecific symptoms and the evolution, in the absence of adequate treatment, is characterized by an expansion of the cutaneous lesion and a spread to deep structures. Infections of tendon sheaths and joints are described, rarely osteomyelitis. Sure diagnosis is hard to obtain and is established from the medical history and microbiological examination. There are no specific therapeutic guidelines. Double or triple antibiotherapy is often effective and should be continued several months after complete resolution of clinical signs. Surgical debridement is required in cases of invasive or resistant infections. We report the case of a young immunocompetent fishmonger with a rare osteocutaneous M. marinum infection of the elbow. Treatment included large surgical excision of infected skin and bone areas and a triple antibiotics administration. Reconstruction have been ensured by a radial collateral artery perforator-based propeller flap, satisfying appropriates functional and cosmetical concerns of this anatomical region. Surgery and appropriate antibiotics treatment were effective and allowed healing of an invasive cutaneous and bone M. marinum infection.

    Background Differentiating melanoma metastasis from benign cutaneous lesions currently requires biopsy or costly imaging, such as positron emission tomography scans. Melanoma metastases have been observed to be subjectively warmer than similarly appearing benign lesions. We hypothesized that infrared (IR) thermography would be sensitive and specific in differentiating palpable melanoma metastases from benign lesions. Materials and methods Seventy-four patients (36 females and 38 males) had 251 palpable lesions imaged for this pilot study. Diagnosis was determined using pathologic confirmation or clinical diagnosis. Lesions were divided into size strata for analysis: 0–5, >5–15, >15–30, and >30 mm. Images were scored on a scale from −1 (colder than the surrounding tissue) to +3 (significantly hotter than the surrounding tissue). Sensitivity and specificity were calculated for each stratum. Logistical challenges were scored. Results IR imaging was able to determine the malignancy of small (0–5 mm) lesions with a sensitivity of 39% and specificity of 100%. For lesions >5–15 mm, sensitivity was 58% and specificity 98%. For lesions >15–30 mm, sensitivity was 95% and specificity 100%, and for lesions >30 mm, sensitivity was 78% and specificity 89%. The positive predictive value was 88%–100% across all strata, and the negative predictive value was 95% for >15–30 mm lesions and 80% for >30 mm lesions. Conclusions Malignant lesions >15 mm were differentiated from benign lesions with excellent sensitivity and specificity. IR imaging was well tolerated and feasible in a clinic setting. This pilot study shows promise in the use of thermography for the diagnosis of malignant melanoma with further potential as a noninvasive tool to follow tumor responses to systemic therapies.

  20. Clinical and morphological characteristics of cutaneous melanoma. (United States)

    Balaban, Jagoda; Ninković Baroš, Djuka; Grujić, Dragana; Starović, Dragana; Ćelić, Milanka


    The incidence of cutaneous melanoma has increased significantly worldwide over the last several decades. The aim of this study is to determine clinical and morphology characteristics of primary melanoma, since some of them are important prognostic factors. This retrospective study included 172 patients. The data were collected by the Consulting team for malignant skin tumors in the Banja Luka Clinical Centre from 2009 to 2011. We did not use dermoscopy as a diagnostic tool in our investigation. We determined that melanoma occurs equally commonly in both sexes, in women in the sixth decade and the seventh in men. The most common sub-type was nodular melanoma (59.5%, P<0.05), followed by superficial spreading (27.8%) and acral lentiginous melanoma (11.4%). The most common localization was on the back in men (34.3%) and on the legs in women (P<0.05). More than half of our patients (55.8%) had melanoma thickness from 1.0 to 4.0 mm, and 38% had a melanoma thicker than 4.0 mm. The average Breslow thickness is 4.6 mm. More women than men had melanoma thicker than 4 mm (P<0.05). Spread of the primary tumor localization was found in 31.4% of patients, more frequently in men than in women (P<0.05). In most cases it was abstraction of lymph nodes (P<0.05). The average thickness of the melanoma in our patients is much higher than the average in the world and the countries of Europe. The results of this study indicate a need for better unique regional registry in this part of Bosnia and Herzegovina and improvement of preventive measures in the early diagnosis of melanoma.

  1. Evaluation of laboratory diagnosis for cutaneous tuberculosis

    Directory of Open Access Journals (Sweden)

    Ilhan Afsar


    Full Text Available Background and Aim: Cutaneous tuberculosis (CTB is still difficult to diagnose due to its varied clinical presentation and limitations of diagnostic methods. The aim of this study was to evaluate the results of diagnostic laboratory tests available for CTB. Materials and Methods: Twenty-six skin biopsy specimens belonging to clinically suspected cases of CTB were studied retrospectively. The specimens were divided into two portions, one part processed for histopathological evaluation and the other was used for microscopy and inoculation for the isolation of mycobacteria. Polymerase chain reaction (PCR technique was applied to 14 of 26 specimens to detect Mycobacterium tuberculosis complex (MTBC DNA. Results: Of the 26 biopsy specimens, 11 were confirmed as CTB by identification of MTBC in culture and/or histopathologic affirmation. Of these, four were lupus vulgaris, four were TB verrucosa cutis, one was scrofuloderma, one was primary inoculation TB, and one was periorifical CTB. Culture for mycobacteria was positive for five (45.45% specimens, while histopathologic affirmation was obtained in ten (90.90% specimens. Acid-fast Bacilli were not demonstrated in any of the specimens on microscopic examination. The PCR was found to be applied to six of the 11 specimens diagnosed as CTB and was positive in two specimens (33.3%, which were positive for growth in culture and histopathological correlation. Conclusion: The recovery rate of MTBC from biopsy specimens was found to be satisfactory for CTB with histopathological correlation, but the combination of culture with a rapid method, PCR, may improve the diagnostic rate.

  5. p53 immunoreactivity is uncommon in primary cutaneous lymphoma. (United States)

    McGregor, J M; Dublin, E A; Levison, D A; MacDonald, D M; Smith, N P; Whittaker, S


    p53 gene mutation appears to play an important role in the development of systemic lymphoma, and may be associated with tumour progression. Its role in cutaneous lymphoma is currently unknown. We examined p53 expression in 55 biopsies of cutaneous lymphoma, including patch-, plaque- and tumour-stage mycosis fungoides (MF), T- and B-cell lymphoma and lymphomatoid papulosis. Strong, homogeneous p53 expression, thought to correlate most closely with p53 gene mutation, was seen in only three cases; in a plaque and tumour from a patient with tumour-stage MF, in plaque-stage MF in a patient without tumours, and in one case of CD30+ large-cell anaplastic lymphoma. These data suggest that p53 gene mutation is not a critical step in the development of the majority of primary cutaneous lymphomas.

    Full Text Available Breast cancer is the most common cancer and the leading cause of cancer death in w omen. Cutaneous metastases are observed in 20 % pa- tients with breast cancer. 36 breast cancer patients with cutaneous metastases were treated with photodynamic therapy in the de partment of laser and photodynamic therapy MRRC. Complete regression was obtained in 33.9 %, partial — in 39 % of cases, the stabilization achieved in 25.4 %, progression noted in 1.7 %. The objective response was obtained in 72.9 % of cases, treatment effect — in 97.4 %. Photodynamic therapy has good treatment results of cutaneous metastases of breast cancer with a small number of side effects.

  7. POLE mutations in families predisposed to cutaneous melanoma

    DEFF Research Database (Denmark)

    Aoude, Lauren G; Heitzer, Ellen; Johansson, Peter


    Germline mutations in the exonuclease domain of POLE have been shown to predispose to colorectal cancers and adenomas. POLE is an enzyme involved in DNA repair and chromosomal DNA replication. In order to assess whether such mutations might also predispose to cutaneous melanoma, we interrogated...... whole-genome and exome data from probands of 34 melanoma families lacking pathogenic mutations in known high penetrance melanoma susceptibility genes: CDKN2A, CDK4, BAP1, TERT, POT1, ACD and TERF2IP. We found a novel germline mutation, POLE p.(Trp347Cys), in a 7-case cutaneous melanoma family....... Functional assays in S. pombe showed that this mutation led to an increased DNA mutation rate comparable to that seen with a Pol ε mutant with no exonuclease activity. We then performed targeted sequencing of POLE in 1243 cutaneous melanoma cases and found that a further ten probands had novel or rare...

  8. Successful treatment of provisional cutaneous mastocytosis with interferon alpha

    Directory of Open Access Journals (Sweden)

    Andrea Rosario


    Full Text Available Mastocytosis is a disorder characterized by the clonal proliferation of mast cells and their accumulation in skin, bone marrow, liver, and spleen. Cutaneous mastocytosis presents in children in over 90% of the cases and any cutaneous manifestation in an adult is the earliest sign of the systemic disease. A 45-year-old patient presented with itchy dark lesions over the body since childhood and Darier's sign was positive. Skin biopsy showed features of mastocytosis and immunohistochemistry was positive for CD34. Since the patient was refractory to treatment with antihistamines and psoralen-ultraviolet A therapy, injections of interferon alpha were given – 3 million IU twice weekly subcutaneously as they have been proven to improve constitutional symptoms. Very few reports of successful treatment of cutaneous mastocytosis using interferon alpha have been published.

  9. Cutaneous leishmaniasis: immune responses in protection and pathogenesis. (United States)

    Scott, Phillip; Novais, Fernanda O


    Cutaneous leishmaniasis is a major public health problem and causes a range of diseases from self-healing infections to chronic disfiguring disease. Currently, there is no vaccine for leishmaniasis, and drug therapy is often ineffective. Since the discovery of CD4(+) T helper 1 (TH1) cells and TH2 cells 30 years ago, studies of cutaneous leishmaniasis in mice have answered basic immunological questions concerning the development and maintenance of CD4(+) T cell subsets. However, new strategies for controlling the human disease have not been forthcoming. Nevertheless, advances in our knowledge of the cells that participate in protection against Leishmania infection and the cells that mediate increased pathology have highlighted new approaches for vaccine development and immunotherapy. In this Review, we discuss the early events associated with infection, the CD4(+) T cells that mediate protective immunity and the pathological role that CD8(+) T cells can have in cutaneous leishmaniasis.

    ) following the insertion of intravascular stents, dental implants, cardiac pacemakers, or implanted gynecologic devices. Despite repeated attempts by researchers and clinicians to further understand this difficult area of medicine, the association between metal sensitivity and cutaneous allergic reactions......Cutaneous reactions to metal implants, orthopedic or otherwise, are well documented in the literature. The first case of a dermatitis reaction over a stainless steel fracture plate was described in 1966. Most skin reactions are eczematous and allergic in nature, although urticarial, bullous......, and vasculitic eruptions may occur. Also, more complex immune reactions may develop around the implants, resulting in pain, inflammation, and loosening. Nickel, cobalt, and chromium are the three most common metals that elicit both cutaneous and extracutaneous allergic reactions from chronic internal exposure...

    Full Text Available Context: Cutaneous metastasis from head and neck cancer is uncommon and it is seen from laryngeal cancer. Cutaneous metastasis from the base of tongue is relatively rare. Case Report: A 55-year-old male, who was a treated case of squamous carcinoma of the base of tongue presented with metastatic nodule on the skin of face and thigh. But, there was complete resolution of the tumor at the primary site. In the present case, clinically obvious cutaneous nodules with metastasis appeared soon after the completion of treatment with concurrent chemo-radiotherapy. The metastasis to the skin of face clinically appeared like an inflammatory lesion. Fine needle aspiration cytology confirmed the diagnosis of metastasis to skin at both the sites. Conclusion: Our case has highlighted that there could be associated occult skin metastasis at the time of diagnosis in squamous carcinoma of the base of tongue.

  12. Cutaneous and systemic hypersensitivity reactions to metallic implants

    DEFF Research Database (Denmark)

    Basko-Plluska, Juliana L; Thyssen, Jacob P; Schalock, Peter C


    Cutaneous reactions to metal implants, orthopedic or otherwise, are well documented in the literature. The first case of a dermatitis reaction over a stainless steel fracture plate was described in 1966. Most skin reactions are eczematous and allergic in nature, although urticarial, bullous......, and vasculitic eruptions may occur. Also, more complex immune reactions may develop around the implants, resulting in pain, inflammation, and loosening. Nickel, cobalt, and chromium are the three most common metals that elicit both cutaneous and extracutaneous allergic reactions from chronic internal exposure......) following the insertion of intravascular stents, dental implants, cardiac pacemakers, or implanted gynecologic devices. Despite repeated attempts by researchers and clinicians to further understand this difficult area of medicine, the association between metal sensitivity and cutaneous allergic reactions...

  13. Giant cutaneous horn in an African woman: a case report

    Directory of Open Access Journals (Sweden)

    Nthumba Peter M


    Full Text Available Abstract Introduction A cutaneous horn is a conical projection of hyperkeratotic epidermis. Though grossly resembling an animal horn, it lacks a bony core. These lesions have been well described in Caucasian patients, as well as in a number of Arabic and Asian patients. Case presentation A young female presented with a large 'horn' of five-year duration, arising from a burn scar. Excision and scalp reconstruction were performed. Histology was reported as verrucoid epidermal hyperplasia with cutaneous horn. Conclusion This may be the first documentation of this lesion in a black African. Although likely rare, it should be considered in the differential diagnosis of dermatologic lesions. Up to 40% of cutaneous horns occur as part of a premalignant or malignant lesion, and surgical extirpation with histological examination is thus more important than the curiosity surrounding these lesions.

  14. MUCI positive cutaneous metastasis with transepidermal elimination from a breast carcinoma. (United States)

    Luna, Amalia; Merino, Maria Emilia; Alberdi, Cecilio G; Abba, Martin C; Segal-Eiras, Amada; Croce, Maria Virginia


    Breast cancer is the most common cause of cutaneous metastases from internal malignancies. Generally, the neoplastic cells are located in the dermis or hypodermis, while a finding of transepidermal elimination on cutaneous metastases is exceptional. In this report we present a patient with perforating cutaneous metastases from breast cancer with mucin 1 expression. Cutaneous, bone, lung, and hepatic lesions were detected two years after the diagnosis of the primary tumor.

  15. Topical Administration of Acylated Homoserine Lactone Improves Epithelialization of Cutaneous Wounds in Hyperglycaemic Rats.

    Lijuan Huang

    Full Text Available Clinicians often experience delayed epithelialization in diabetic patients, for which a high glucose condition is one of the causes. However, the mechanisms underlying delayed wound closure have not been fully elucidated, and effective treatments to enhance epithelialization in patients with hyperglycaemia have not been established. Here we propose a new reagent, acylated homoserine lactone (AHL, to improve the delayed epithelialization due to the disordered formation of a basement membrane of epidermis in hyperglycaemic rats. Acute hyperglycaemia was induced by streptozotocin injection in this experiment. Full thickness wounds were created on the flanks of hyperglycaemic or control rats. Histochemical and immunohistochemical analyses were performed to identify hyperglycaemia-specific abnormalities in epidermal regeneration by comparison between groups. We then examined the effects of AHL on delayed epithelialization in hyperglycaemic rats. Histological analysis showed the significantly shorter epithelializing tissue (P < 0.05, abnormal structure of basement membrane (fragmentation and immaturity, and hypo- and hyperproliferation of basal keratinocytes in hyperglycaemic rats. Treating the wound with AHL resulted in the decreased abnormalities of basement membrane, normal distribution of proliferating epidermal keratinocytes, and significantly promoted epithelialization (P < 0.05 in hyperglycemic rats, suggesting the improving effects of AHL on abnormal epithelialization due to hyperglycemia.

  16. Topical Administration of Manuka Oil Prevents UV-B Irradiation-Induced Cutaneous Photoaging in Mice

    Directory of Open Access Journals (Sweden)

    Oh Sook Kwon


    Full Text Available Manuka tree is indigenous to New Zealand, and its essential oil has been used as a traditional medicine to treat wounds, fever, and pain. Although there is a growing interest in the use of manuka oil for antiaging skin care products, little is known about its bioactivity. Solar ultraviolet (UV radiation is the primary environmental factor causing skin damage and consequently premature aging. Therefore, we evaluated manuka oil for its effects against photoaging in UV-B-irradiated hairless mice. Topical application of manuka oil suppressed the UV-B-induced increase in skin thickness and wrinkle grading in a dose-dependent manner. Application of 10% manuka oil reduced the average length, depth, and % area of wrinkles significantly, and this was correlated with inhibition of loss of collagen fiber content and epidermal hyperplasia. Furthermore, we observed that manuka oil could suppress UV-B-induced skin inflammation by inhibiting the production of inflammatory cytokines. Taken together, this study provides evidence that manuka oil indeed possesses antiphotoaging activity, and this is associated with its inhibitory activity against skin inflammation induced by UV irradiation.

  17. Topical mechlorethamine: cutaneous changes in patients with mycosis fungoides after its administration

    Energy Technology Data Exchange (ETDEWEB)

    Price, N.M.


    Six patients with mycosis fungoides were treated with topical mechlorethamine hydrochloride for periods of two to four years. Clinical and histological studies for radiomimetic and radiodermatitis-like effects failed to demonstrate any abnormalities. The only observed changes were generalized hyperpigmentation of the skin and melanin-containing melanophages in the papillary dermis. We consider that the long-term use of topical mechlorethamine may be a safe form of therapy, but that a continuous indefinite follow-up of patients on this medication should be mandatory.

  18. Lenalidomide for refractory cutaneous manifestations of pediatric systemic lupus erythematosus. (United States)

    Wu, E Y; Schanberg, L E; Wershba, E C; Rabinovich, C E


    Objective Cutaneous manifestations of pediatric systemic lupus erythematosus cause significant morbidity. Lenalidomide, a thalidomide analogue, has shown promise treating cutaneous lupus erythematosus in adults. Our objective was to evaluate lenalidomide's efficacy and safety in treating refractory cutaneous manifestations of pediatric systemic lupus erythematosus. Methods We performed a retrospective chart review of 10 adolescents who received lenalidomide for recalcitrant cutaneous lupus erythematosus. Information was gathered at drug initiation and 6-month follow-up. The Wilcoxon matched-pairs signed-rank test was used to assess change in quantitative parameters of disease activity. Results Nine subjects were girls and six were African-American. Indications for lenalidomide treatment included alopecia, nasal and oral ulcers, extensive malar rash, discoid lesions, bullous lesions, panniculitis, cutaneous vasculitis, and Raynaud's phenomenon with digital ulcerations. Within 6 months, all patients demonstrated complete or near resolution based on physician report. Prednisone dose decreased from a mean 23.5 mg (SD± 13.3) to 12.25 mg (SD± 9.2) ( P= 0.008). Sedimentation rate decreased from a mean 29 mm/hour (SD± 31.5) to 17 mm/hour (SD± 18.1) ( P= 0.004). Lenalidomide was well tolerated. Conclusion Lenalidomide is an effective and safe treatment for a spectrum of dermatological conditions in pediatric systemic lupus erythematosus. Its use may allow a reduction in prednisone dose and decreased disfigurement. Prospective study is needed to clarify lenalidomide's role in treating cutaneous manifestations of systemic lupus erythematosus.

    Wang, Kui-Rong; Jia, Yuan-Jing; Zhou, Shui-Hong; Wang, Qin-Ying; Bao, Yang-Yang; Feng, Zhi-Ying; Yao, Hong-Tian; Fan, Jun


    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    Udayakumar P


    Full Text Available Background: Chronic renal failure (CRF presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF undergoing hemodialysis. Methods: One hundred patients with CRF on hemodialysis were examined for cutaneous changes. Results: Eighty-two per cent patients complained of some skin problem. However, on examination, all patients had at least one skin lesion attributable to CRF. The most prevalent finding was xerosis (79%, followed by pallor (60%, pruritus (53% and cutaneous pigmentation (43%. Other cutaneous manifestations included Kyrle′s disease (21%; fungal (30%, bacterial (13% and viral (12% infections; uremic frost (3%; purpura (9%; gynecomastia (1%; and dermatitis (2%. The nail changes included half and half nail (21%, koilonychia (18%, onychomycosis (19%, subungual hyperkeratosis (12%, onycholysis (10%, splinter hemorrhages (5%, Mees′ lines (7%, Muehrcke′s lines (5% and Beau′s lines (2%. Hair changes included sparse body hair (30%, sparse scalp hair (11% and brittle and lusterless hair (16%. Oral changes included macroglossia with teeth markings (35%, xerostomia (31%, ulcerative stomatitis (29%, angular cheilitis (12% and uremic breath (8%. Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi′s sarcoma were also observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

    Meryem Ozlem Kutuk


    Full Text Available Cutaneous allergic reactions due to drug intake may be triggered by many types of drugs such as atropine, anticonvulsants and benzodiazepines. But allergic reactions due to benzodiazepines are extremely rare. Alprazolam is a benzodiazepine which may be useful for refractory idiopathic urticaria due to antihistaminergic effect. Although antihistaminergic effect of alprazolam, a cold urticaria case and an angioedema case induced by alprazolam are known in the literature. In the case, we present a child suffering from cutaneous allergic reaction due to alprazolam at the first dose taken. [Cukurova Med J 2016; 41(2.000: 400-402

    A Berih


    Full Text Available A Canadian soldier incurred a nonhealing traumatic skin ulcer while on duty in Somalia. The diagnosis of localized cutaneous diphtheria was confirmed by isolation of a toxigenic strain of Corynebacterium diphtheriae from the ulcer. The patient was placed in isolation and treated with erythromycin and penicillin for 10 days without antitoxin. He was released when two consecutive daily cultures were negative. Public health officials evaluated his wife, two children and close contacts for carriage, but no carriers or secondary cases were identified. Cutaneous diphtheria as a diagnostic and management patient problem and potential public health problem are discussed.

    Baradkar V


    Full Text Available Saksenaea vasiformis is an emerging zygomycete species, most often associated with cutaneous, subcutaneous and rhino- orbito-cerebral infections. Herein, we report a case of cutaneous zygomycosis of face caused by Saksenaea vasiformis in a 54-year-old immunocompetent female. The diagnosis was carried out by microscopy using KOH mount, Gram staining, Gomori′s methenamine silver staining, hemotoxylin and eosin staining and culture on Sabouraud′s Dextrose agar without actidione. Slide cultures were put up on Czapek Dox agar, which showed typical flask-shaped sporangium with rhizoids. The patient was treated successfully with intravenous amphotericin B.

  6. Cutaneous Ossifying Fibroma in a Neon Tetra (Paracheirodon innesi). (United States)

    Murphy, B; Imai, D M


    A cutaneous proliferative mass was identified arising from the caudal peduncle of a captive neon tetra fish (Paracheirodon innesi). The lesion was histologically consistent with an ossifying fibroma (OF), a fibro-osseous proliferative lesion typically identified in the jaws or tooth-associated supportive tissues of mammals. Although it has been previously reported, there is no recent report of this lesion occurring in a fish. This is the first report of a cutaneous ossifying fibroma in a characin fish. The authors speculate on the pathogenesis of this lesion, which may have arisen from the scale-associated mesenchymal tissues.

  7. Differences in cutaneous wound healing between dogs and cats. (United States)

    Bohling, Mark W; Henderson, Ralph A


    Regardless of the species involved, wound healing follows a predictable course of overlapping phases. In spite of these commonalities, significant species differences in cutaneous wound healing have been uncovered in the Equidae and, more recently, between the dog and cat. It has also recently been shown that the subcutaneous tissues play an important supporting role in cutaneous wound healing, which may help to ex-plain healing differences between cats and dogs. These discoveries may improve veterinarians' understanding of problem wound healing in the cat and, hopefully, lead to better strategies for wound management in this sometimes troublesome species.

  8. Abnormal pigmentation within cutaneous scars: A complication of wound healing

    Directory of Open Access Journals (Sweden)

    Sarah Chadwick


    Full Text Available Abnormally pigmented scars are an undesirable consequence of cutaneous wound healing and are a complication every single individual worldwide is at risk of. They present a challenge for clinicians, as there are currently no definitive treatment options available, and render scars much more noticeable making them highly distressing for patients. Despite extensive research into both wound healing and the pigment cell, there remains a scarcity of knowledge surrounding the repigmentation of cutaneous scars. Pigment production is complex and under the control of many extrinsic and intrinsic factors and patterns of scar repigmentation are unpredictable. This article gives an overview of human skin pigmentation, repigmentation following wounding and current treatment options.

    Gonzales-Viera, O; Bauer, G; Bauer, A; Aguiar, L S; Brito, L T; Catão-Dias, J L


    An adult female common snapping turtle (Chelydra serpentina) had a mass on the plantar surface of the right forelimb that was removed surgically. Microscopical examination revealed many spindle cells with mild anisocytosis and anisokaryosis and a surrounding collagenous stroma. There were no mitoses. Immunohistochemistry showed that the spindle cells expressed vimentin, but not desmin. A diagnosis of cutaneous fibroma was made. Tumours are reported uncommonly in chelonian species. Cutaneous fibroma has been diagnosed in an alligator snapping turtle (Macrochelys temminckii), but not previously in a common snapping turtle.

  10. Penile cutaneous horn: An enigma-newer insights and perspectives

    Directory of Open Access Journals (Sweden)

    Kaliaperumal Karthikeyan


    Full Text Available Cutaneous horn refers to unusually cohesive keratinized material and not a true pathologic diagnosis. Though cutaneous horn has been described at various sites, horn over the penis is very rare and represents the most unusual site. The role of chronic irritation, phimosis, surgical trauma and radiotherapy have been implicated in penile horn formation. Penile horns present as elongated, keratinous, white or yellowish projections that range from a few millimeters to centimeters in size arising from the glans penis. Histopathology of the keratotic mass reveals nothing but keratin. The underlying mass may vary from verruca vulgaris to squamous cell carcinoma. The treatment is based on the pathology.

  11. Cutaneous zygomycosis: A possible postoperative complication in immunocompetent individuals

    Directory of Open Access Journals (Sweden)

    Tilak Ragini


    Full Text Available Fungi in the class of zygomycetes usually produce serious infections in diabetics and immunocompromised hosts. Cutaneous zygomycosis is a less common form, with an unpredictable extent of anatomical involvement and clinical course. Here, we report two cases of primary cutaneous zygomycosis as postoperative complications in otherwise healthy females. Zygomycosis was suspected and specimens from the surgical debridement were examined by microbiological and histopathological studies for confirming the clinical diagnosis. Rapid diagnosis, liposomal amphotericin B, and proper debridement of affected tissue are necessary to avoid a fatal outcome.

  12. Cutaneous in vivo metabolism of topical lidocaine formulation in human skin

    DEFF Research Database (Denmark)

    Rolsted, K; Benfeldt, E; Kissmeyer, A-M


    Little is known about the metabolising capacity of the human skin in relation to topically applied drugs and formulations. We chose lidocaine as a model compound since the metabolic pathways are well known from studies concerning hepatic metabolism following systemic drug administration. However......, the enzymes involved are also expressed in the skin. Hence, the aim of the current study was to investigate the extent of the cutaneous in vivo metabolism of topically applied lidocaine in human volunteers. A dose of 5 mg/cm(2) of Xylocaine(R) (5% lidocaine) ointment was applied onto the buttock skin...... of the volunteers. After 2 h, residual formulation was removed, and two 4-mm punch biopsies were taken from each volunteer. The quantity of lidocaine extracted from the skin samples (epidermis + dermis) was 109 +/- 43 ng/mm(2) skin. One metabolite (monoethylglycine xylidide, MEGX) was detected in skin from 7...

    Full Text Available The clinical manifestations and prognosis of cutaneous leishmaniasis (CL can be influenced by the immune response of the patient and the species of the parasite. A case of atypical clinical presentation of CL, with development of non-characteristic lesions, poor response to therapy, and a long time to resolution is reported. Confirmatory laboratory tests included parasite detection, indirect immunofluorescence, Montenegro skin test, polymerase chain reaction, and parasite identification by multilocus enzyme electrophoresis. The parasite was identified as Leishmaniabraziliensis. The lesion was unresponsive to three complete courses of N-methylglucamine antimoniate intramuscular, and to treatment with pentamidine. The patient did not tolerate amphotericin B. The lesion finally receded after treatment with intravenous N-methylglucamine antimoniate. It is essential to ensure the accuracy of diagnosis and the appropriate treatment, which can include the use a second choice drug or a different route of administration.

  14. Cutaneous Necrotizing Vasculitis and Leukopenia in a Cocaine User: Is Levamisole the Culprit?

    Directory of Open Access Journals (Sweden)

    Lara El Khoury


    Full Text Available Levamisole is an antihelminthic drug banned by the US Food and Drug Administration (FDA in 2000 because of its dangerous side effects. Over the past few years, it has been identified as an adulterant in cocaine and reported to cause cutaneous vasculitis in cocaine users. The health burden of levamisole is serious since it is estimated that over 5 million Americans use cocaine and that 70% of the cocaine used in the USA contains levamisole. In this paper we report the case of a 23-year-old female cocaine user that presented with purpuric rash and skin necrosis, found to have positive c-ANCA and anti-proteinase 3 antibodies. Her skin biopsy showed fibroconnective tissue with signs of necrosis, acute and chronic inflammation, and thrombus formation. She was diagnosed with levamisole-induced vasculitis and successfully treated with withdrawal of cocaine use and local wound care.

    Wang Ena


    Full Text Available Abstract Background Although the sequence of events leading to wound repair has been described at the cellular and, to a limited extent, at the protein level this process has yet to be fully elucidated. Genome wide transcriptional analysis tools promise to further define the global picture of this complex progression of events. Study Design This study was part of a placebo-controlled double-blind clinical trial in which basal cell carcinomas were treated topically with an immunomodifier – toll-like receptor 7 agonist: imiquimod. The fourteen patients with basal cell carcinoma in the placebo arm of the trial received placebo treatment consisting solely of vehicle cream. A skin punch biopsy was obtained immediately before treatment and at the end of the placebo treatment (after 2, 4 or 8 days. 17.5K cDNA microarrays were utilized to profile the biopsy material. Results Four gene signatures whose expression changed relative to baseline (before wound induction by the pre-treatment biopsy were identified. The largest group was comprised predominantly of inflammatory genes whose expression was increased throughout the study. Two additional signatures were observed which included preferentially pro-inflammatory genes in the early post-treatment biopsies (2 days after pre-treatment biopsies and repair and angiogenesis genes in the later (4 to 8 days biopsies. The fourth and smallest set of genes was down-regulated throughout the study. Early in wound healing the expression of markers of both M1 and M2 macrophages were increased, but later M2 markers predominated. Conclusion The initial response to a cutaneous wound induces powerful transcriptional activation of pro-inflammatory stimuli which may alert the host defense. Subsequently and in the absence of infection, inflammation subsides and it is replaced by angiogenesis and remodeling. Understanding this transition which may be driven by a change from a mixed macrophage population to predominately M2

  17. Selective vascular injury during cutaneous laser therapy (United States)

    Tunnell, James William

    Pulsed laser irradiation in conjunction with cryogen spray cooling (CSC) can induce selective vascular injury to remove cutaneous hypervascular malformations such as port wine stains (PWS), hemangiomas, and facial veins. In this group of studies, we characterized the cryogen heat removal process and determined the effects of pulsed laser irradiation in conjunction with cryogen spray cooling of human skin. First, we employed an inverse heat conduction algorithm to measure the thermal boundary condition due to CSC in in vitro skin phantoms. Second, we developed a mathematical model of laser irradiation in conjunction with CSC in human skin. We determined tissue damage and temperature profiles due to varying combinations of laser pulse duration, radiant exposure, and CSC application times. Finally, we used ex vivo and in vivo human skin to determine the effects of high radiant exposures and CSC on epidermal and vascular injury. CSC induces a dynamic cooling effect, removing heat from the skin both during and following the spurt application time. Residual cryogen, deposited on the skin surface during the cryogen spurt, remains on the skin surface several times as long as the as cryogen spurt itself. The heat removal rate during the cryogen spurt is greatest; however, the total energy removed following the cryogen spurt is also substantial (approximately half as much as during the spurt application time). CSC was effective in protecting the human skin epidermis in light to moderately pigmented skin. Mathematical modeling, ex vivo, and in vivo studies showed that the epidermal damage threshold could be increased by a factor of approximately two. Increased radiant exposures increased the risk of non-selective vascular injury observed in histology as injury to the epidermis and perivascular collagen; however, proper choice of cryogen cooling durations resulted in the elimination of epidermal injury as well as perivascular tissue injury. In addition, higher radiant

    Directory of Open Access Journals (Sweden)

    Sunil Kumar


    Full Text Available Cutaneous horn is a conical, dense, and hyperkeratotic protrusion that often appears similar to the horn of an animal. Giant cutaneous horns are rare; no incidence or prevalence has been reported. The significance of cutaneous horns is that they occur in association with, or as a response to, a wide variety of underlying benign, premalignant, and malignant cutaneous diseases. A case of giant cutaneous horn of left oral commissure along with carcinoma left buccal mucosa is reported here as an extremely rare oral/perioral pathology.

    Wei He


    Full Text Available Objective: To explore the clinical characteristics, diagnosis and prognosis of local severe cutaneous reactions as result of the treatment with Hirudoid. Methods: One case of severe cutaneous reactions as result of the treatment with Hirudoid was reported and the relevant literatures were reviewed. Results: The site of puncture of left arm occurred non-leakage phlebitis with local pain after chemotherapy. The patient was applied the Hirudoid to the affected areas 2 times daily. After 2 days, local skin felt a kind of burning pain and it seems to be getting worse. The skin lesions began as pruritic red macules or papules. It became swelled and bleeding after scratching. We considered that the cutaneous reactions were an allergic response to Hirudoid. We discontinued the Hirudoid and desensitization treatment was used on cure, but it failed to respond to the medical treatment. A hot compress with 50% magnesium sulphate solution can reduce swelling and alleviate pain. Scales of skin peel off and weaved the new skin after 10 days. Conclusion: The case of local severe cutaneous reactions as result of the treatment with Hirudoid is very rare. A hot compress with 50%  magnesium sulphate solution can help to relieve the discomfort.

    Boaventura, Viviane S; Cafe, Virginia; Costa, Jackson; Oliveira, Fabiano; Bafica, Andre; Rosato, Andrea; de Freitas, Luiz A R; Brodskyn, Claudia; Barral-Netto, Manoel; Barral, Aldina


    Mucosal leishmaniasis (ML) is often clinically silent until reaching a highly advanced state. In this prospective study, 6 of 220 patients with early cutaneous leishmaniasis were diagnosed with mucosal involvement by otorhinolaryngological examination (a rate similar to the reported rate of late ML). Detection of early ML may represent an important strategy in preventing severe mucosal destruction in human leishmaniasis.

    Full Text Available Smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. This study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better classification and diagnosis. The six year data base of our center was reviewed and 25 patients with cutaneous leiomyoma were included in this study. Of 25 patients, 5 were female and 20 were male. 5 patients had angioleiomyoma (ALM and 20 had pilar leiomyoma (PLM. ALM had following characteristics: dilated vascular canals intermingled with compact smooth muscle bundles; well circumscribe counter and myxoid and hyaline changes through the tumor. In contrast, PLMs had following histologic features: poor defined outline, entrapped hair follicles and eccrine glands, acanthosis and elongated rete ridges with hyperpigmentation and smooth muscle bundles which are interdigitated with elongated rete ridges. Here we introduced some distinct histological features for each subtype of the cutaneous leiomyoma which can lead to create novel criteria for classification and diagnosis of the lesion.

  9. Vaccines and vaccination strategies against human cutaneous leishmaniasis. (United States)

    Okwor, Ifeoma; Uzonna, Jude


    One might think that the development of a vaccine against cutaneous leishmaniasis would be relatively straightforward because the type of immune response required for protection is known and natural immunity occurs following recovery from primary infection. However, there is as yet no effective vaccine against the disease in humans. Although vaccination in murine studies has yielded promising results, these vaccines have failed miserably when tested in primates or humans. The reasons behind these failures are unknown and remain a major hurdle for vaccine design and development against cutaneous leishmaniasis. In contrast, recovery from natural, deliberate or experimental infections results in development of long-lasting immunity to re-infection. This so called infection-induced resistance is the strongest anti-Leishmania immunity known. Here, we briefly review the different approaches to vaccination against cutaneous leishmaniasis and argue that vaccines composed of genetically modified (attenuated) parasites, which induce immunity akin to infection-induced resistance, may provide best protection against cutaneous leishmaniasis in humans.

    Full Text Available BACKGROUND Anthrax is a disease of herbivorous animals. Humans incidentally acquire the cutaneous disease by handling infected dead animals and their products. Sporadic cases of human anthrax have been reported from Southern India. METHODS Fifteen tribal men, one woman, one child from various places near Paderu presented with painless ulcers associated with vesiculation and oedema of the surrounding skin on the extremities without any constitutional symptoms. There was a history of slaughtering and consumption of a dead goat ten days - 2 weeks prior to the development of skin lesions. Three days later another 19 members came from the same area with same complaints. Clinically, cutaneous anthrax was suspected and smears, swabs, and punch biopsies were taken for culture and identification by Polymerase Chain Reaction (PCR. All the cases were treated with intravenous antibiotics followed by oral antibiotics. Appropriate health authorities were alerted and proper control measures were employed. RESULTS Smears from the cutaneous lesions of some patients were found to be positive for Bacillus anthracis and this was confirmed by polymerase chain reaction. All the cases responded to antibiotics. CONCLUSION We report thirty six cases of cutaneous anthrax in a non-endemic district, Visakhapatnam, Andhra Pradesh.

  15. Cryptococcal meningitis with secondary cutaneous involvement in an immunocompetent host. (United States)

    Tabassum, Saadia; Rahman, Atiya; Herekar, Fivzia; Masood, Sadia


    Cryptococcosis is a potentially fatal fungal disease caused by variants of Cryptococcus neoformans species.  The respiratory tract is the usual portal of entry, with a peculiar predilection to invade the central nervous system.  The skin can be secondarily involved in disseminated infection or be exceptionally involved as primary cutaneous infection by inoculation.  The disease is mostly seen in immunodeficiency states.  The diagnosis is frequently unsuspected in immunocompetent patients. We report a case of disseminated cryptococcal meningitis in an immunocompetent young adult. The cutaneous eruption prompted the accurate diagnosis.  The patient, a 20-year-old female, had fever, cough, headache and intractable vomiting for the past two months and was being managed as a case of tuberculous meningitis. Two weeks after starting antituberculous treatment she developed umbilicated papules on the head and neck region. Necessary laboratory workup identified C. neoformans in cerebrospinal fluid (CSF) and skin specimens.  The titers of cryptococcal antigen were measured in CSF and serum for diagnostic and prognostic purposes.  Anti-fungal treatment resulted in regression of the cutaneous lesions and resolution of systemic complaints. The case highlights the need for high degree of suspicion, especially in healthy young adults, in the diagnosis of cryptococcosis. The cutaneous eruptions can be the first manifestation or a diagnostic clue of enormous significance.

  16. Poikiloderma-like cutaneous amyloidosis in an ethnic Chinese girl. (United States)

    Ho, M H; Chong, L Y


    Primary cutaneous amyloidosis is the deposition of amyloid in the skin without involvement of internal organs. It is easily diagnosed when presented in its typical manifestation. Atypical or rare clinical presentations can pose diagnostic difficulties. Poikiloderma-like cutaneous amyloidosis (PCA), a rare variant of primary cutaneous amyloidosis, was first reported in the literature in 1936 (1). It is characterised by: 1) poikilodermatous skin lesions; 2) lichenoid papules; 3) cutaneous amyloid deposit in the pigmented and lichenoid lesions; 4) light sensitivity; 5) short stature; and 6) other features such as blister formation or palmoplantar keratosis. Ogino coined the term PCA syndrome when these unusual features present early in life (2). We report a 26-year-old Chinese woman who presented with poikilodermatous skin lesions and was misdiagnosed as poikiloderma atrophica vasculare (PAV) on the basis of clinical appearance without any histological proof. The diagnosis of PCA was made after skin biopsy which showed amyloid deposits in the skin. This condition can easily be confused with other true poikiloderma skin diseases. Histology is important in confirming the diagnosis.

  20. [Myositis and the skin: cutaneous manifestations of dermatomyositis]. (United States)

    Jinnin, Masatoshi


    Idiopathic inflammatory myopathies include dermatomyositis, polymyositis, and inclusion body myositis. Among them, cutaneous manifestations are observed most frequently in dermatomyositis. While dermatomyositis commonly affects the skin and muscles, it can also affect the lungs and other organs. Dermatomyositis presenting clinically and histopathologically with typical cutaneous lesions, but without myositis, is called amyopathic dermatomyositis. Given that the Bohan and Peter criteria cannot distinguish amyopathic dermatomyositis, understanding the characteristic skin manifestations may be essential for diagnosing this condition. The cutaneous manifestations of dermatomyositis are thought to be the result of the Koebner phenomenon, vasculopathy, or photosensitivity; manifestations include various eruptions, such as heliotrope rush, Gottron's sign, Gottron's papules, mechanic's hand, nail-fold bleeding, skin ulcer, vasculitis, flagellate erythema, V-sign, and Shawl sign. The presence of multiple types of eruptions can help diagnose the disease. Several skin diseases, including adult Still's disease, contact dermatitis, and sarcoidosis, can mimic the cutaneous manifestations of dermatomyositis. Skin biopsy is useful for differential diagnoses. Histopathologically, dermatomyositis of the skin is characterized by liquefaction degeneration, vacuolar degeneration, edema, and mucin deposition. Dermatologists, neurologists, and rheumatologists are responsible for the diagnosis and management of dermatomyositis, in cooperation with pulmonologists, pediatricians, and pathologists. This review aims to provide clinicians with recent findings regarding skin involvement in dermatomyositis.

  1. Cutaneous Mycoses among Rice Farmers in Anambra State, Nigeria

    Directory of Open Access Journals (Sweden)

    Chito Clare Ekwealor


    Full Text Available Rice grain is one of the world's most important food crops, and its cultivation is a major occupation in Anambra State, Nigeria. These rice farmers are exposed to various agents that predispose them to cutaneous mycoses. The aim of this work was to screen rice farmers for lesions suggestive of cutaneous mycoses and to isolate and identify fungal agents associated with the infection. This survey was carried out between November 2009 and June 2011 in Anambra State, Nigeria. Clinical samples collected from 201 farmers with lesions suggestive of cutaneous mycoses were processed and the organisms identified. Questionnaires were used to obtain other necessary data and were statistically analyzed. Of the 2,580 rice farmers screened, 201 (7.79% showed positive lesions. Organisms recovered included Microsporum audouinii, Microsporum ferrugineum, Trichophyton megnini, Trichophyton tonsurans, Trichophyton rubrum, Aspergillus terrus, Aspergillus candidus, Aspergillus scleriotorum, Aspergillus niger, Aspergillus flavus, Scopulariopsis sp., Chrysosporium sp., Eupenicillium javanicum, Fusarium sp., Penicillium aculeatum, and Penicillium pinophilum. At the end of this work, onychomycosis was observed to be the most prevalent with nondermatophyte molds now becoming very important agents of cutaneous mycoses among rice farmer.

  4. [Rare cutaneous manifestaions of lupus erythematosus. A clinical overview]. (United States)

    Kuhn, A; Schuppe, H C; Ruzicka, T; Lehmann, P


    Lupus erythematosus (LE) is a disease with a wide spectrum of cutaneous and systemic manifestations and has been the subject of many studies over several decades. Clinical features of patients with LE show a great variation, and for this reason it is difficult to develop a unifying concept of this disease. Consequently, this has led to the identification of subsets which have been defined by constellations of clinical and photobiological features, histological changes as well as laboratory abnormalities. Besides the characteristic classical forms such as systemic LE (SLE), subacute cutaneous LE (SCLE), and discoid LE (DLE), there are uncommon variants of LE which often lead to diagnostic difficulties. Bullous LE (BLE) and urticarial vasculitis are listed as characteristic but non-specific manifestations of systemic LE. LE tumidus (LET), LE hypertrophic/verrucous (LEHV), chilblain LE, and LE profundus (LEP) are uncommon subtypes of chronic cutaneous LE. Annular erythema and papulonodular mucinosis are further uncommon cutaneous manifestations of LE. This clinical review summarizes the typical features of the uncommon forms of LE in order to improve clinical diagnostic precision and to achieve a better differentiation of the subtypes.

  5. Chronic Urticaria: A Cutaneous Manifestation of Celiac Disease

    Directory of Open Access Journals (Sweden)

    Jessica Haussmann


    Full Text Available Celiac disease, or gluten-sensitive enteropathy, is an immune-mediated disease of the small bowel that results in malabsorption. It classically presents with gastrointestinal symptoms including chronic diarrhea, weight loss, abdominal bloating and anorexia. It is becoming more frequently identified in asymptomatic patients with a diagnosis of deficiencies related to malabsorption of iron, folic acid, vitamin B12 and vitamin D. It is increasingly identified as a cause for early or refractory osteoporosis. Occasionally, celiac disease presents with cutaneous manifestations alone. Dermatitis herpetiformis is a well-recognized cutaneous manifestation of celiac disease. Other cutaneous manifestations include alopecia, angular stomatitis and aphthous ulcerations. Described here is a case of a 24-year-old woman who presented with intermittent urticaria and gastrointestinal complaints. She was found to have celiac disease on small-bowel biopsy. Both her gastrointestinal symptoms and urticaria resolved when she was put on a gluten-free diet, suggesting that her urticaria was a cutaneous manifestation of celiac disease.

  6. mRNA and DNA PCR tests in cutaneous tuberculosis

    Directory of Open Access Journals (Sweden)

    Chandanmal Suthar


    Full Text Available Background: The microbiologic diagnosis of cutaneous tuberculosis is difficult because most lesions harbor only a small number of mycobacteria that cannot usually be detected by staining for the organism or by culture. Nucleic acid amplification tests based on the polymerase chain reaction (PCR are potentially useful in this situation. Aims: To evaluate the utility of mRNA PCR and DNA PCR in the diagnosis of cutaneous tuberculosis. Methods: Biopsies from 28 cases of cutaneous tuberculosis and 19 controls with other diseases were subjected to microbiologic tests including direct smears for mycobacteria, culture and both mRNA PCR and DNA PCR. The laboratory was blinded to the clinical diagnosis. Results: None of the patients or controls showed a positive reaction on mRNA PCR test. Seven of 28 cases and 5 out of 19 controls showed a positive result on DNA PCR test yielding a sensitivity of 25% and a specificity of 73.7%. Conclusion: The results of PCR tests in cutaneous tuberculosis should be interpreted in the light of clinical and histopathological findings.

  7. Primary cutaneous and subcutaneous leiomyosarcomas: evolution and prognostic factors. (United States)

    Aneiros-Fernandez, Jose; Antonio Retamero, Juan; Husein-Elahmed, Husein; Ovalle, Francisco; Aneiros-Cachaza, Jose


    Cutaneous and subcutaneous leiomyosarcomas (LMS) are uncommon neoplasms. We reviewed the MEDLINE database to assess their rates of recurrence and metastasis, mortality and recommended follow-up period. Other prognostic factors were also studied. This review included 112 subcutaneous LMS and 313 cutaneous LMS. In subcutaneous LMS, we observed that rates of recurrence, metastasis and mortality were 36.63%, 43.23% and 37.82%, respectively, after a median follow-up period of 4.40 years, while in cutaneous LMS those figures were 24.40%, 4.22% and 3.33%, respectively, after a median follow-up period of 3.45 years. Although subcutaneous and cutaneous LMS show similar morphologic features, the latter show less tendency to recur and metastasize; in certain cases they both may be the cause of death. For these reasons we suggest avoiding the term "atypical intradermal smooth muscle neoplasm". Location, size and histologic grade are essential prognostic factors for superficial LMS. Recurrence after incomplete excision can be avoided when performed with a surgical margin of at least 1 cm. Follow-up should be at least five years.

  11. Ethnic differences in the epidemiology of cutaneous lupus erythematosus in New Zealand. (United States)

    Jarrett, P; Thornley, S; Scragg, R


    Background The prevalence and variation by ethnicity of cutaneous lupus in New Zealand is not known. Therefore, a cross-sectional study to determine the prevalence and variation by ethnicity of cutaneous lupus in the ethnically diverse community of South Auckland, New Zealand, was undertaken. Methods Multiple sources were examined to determine the prevalence of acute cutaneous lupus erythematosus, subacute cutaneous erythematosus and discoid lupus erythematosus. Ethnicities examined were European, Māori/Pacific and Indian/Asian. Capture-recapture was used to determine the overall population prevalence of cutaneous lupus. Results A total of 145 cases of cutaneous lupus were identified. There were 22 men and 123 women, with an average age (standard deviation), respectively, of 46.4 (±21.5) and 43.1 (±14.8) years. There were 53 cases of acute cutaneous lupus erythematosus, 19 cases of subacute cutaneous erythematosus and 66 cases of discoid lupus erythematosus. The age and sex adjusted relative risk (95% confidence interval; CI) of Māori/Pacific compared to the European population was 2.47 (95% CI 1.67-3.67) for all types of cutaneous lupus, 1.60 (95% CI 0.84-3.18) for acute cutaneous lupus erythematosus, 0.09 (95% CI 0.01-1.1) for subacute cutaneous erythematosus and 5.96 (95% CI 3.06-11.6) for discoid lupus erythematosus. The overall prevalence of cutaneous lupus was 30.1 (95% CI 25.5-35.4) per 100,000. However, capture-recapture estimated the unadjusted prevalence of cutaneous lupus to be 86.0 (95% CI 78.1-94.7) per 100,000. Conclusion Māori and Pacific people in Auckland, New Zealand, have a greater relative risk of all types of cutaneous lupus compared to the European population and a particularly high risk of discoid lupus erythematosus.

  14. Effectiveness of meglumine antimoniate against L. tropica in a recently emerged focus of cutaneous leishmaniasis in Birjand, eastern Islamic Republic of Iran. (United States)

    Karamian, M; Bojd, M S Faroghi; Salehabadi, A; Hemmati, M; Barati, D A


    With limited options to treat cutaneous leishmaniasis, constant monitoring of the rate of resistance to pentavalent antimony-based drugs is needed. This study identified the infecting Leishmania species and evaluated the results of meglumine antimoniate (Glucantime®) therapy in a new focus of cutaneous leishmaniasis in Birjand, eastern Islamic Republic of Iran. Smears from 150 patients showed that 141 patients were infected by L. tropica and 9 by L. major. In total, 141 patients with L. tropica infection completed Glucantime® treatment and follow-up; 63.8% were treated intralesionally and 36.2% by intramuscular administration. The overall success rate after one course of therapy with Glucantime® was 96.5% (136/141), and all the failures (5/141) occurred with intramuscular injections. Statistical analysis showed a significant difference between the failure rates of intramuscular and intralesional injections. Children < 10 years old had a significantly higher failure rate than adults.

  15. Oxidant and antioxidant events during epidermal growth factor therapy to cutaneous wound healing in rats. (United States)

    Kalay, Zeynep; Cevher, Sule Coskun


    Cutaneous wound healing is a highly complex process, which includes inflammation, cell proliferation, matrix deposition and remodelling phases. Various growth factors, like epidermal growth factor (EGF), play an important role during wound healing. However, little is known about relationship between EGF and oxidant-antioxidant events in cutaneous wound healing models. Thus we planned to evaluate the connection between EGF therapy and oxidative stress in dermal tissue followed by wounding. Fifty-four adult male Wistar-albino rats were randomly divided into three groups: control, untreated and topical EGF administrated group. A linear full-thickness excision of 40 mm in length on both sides of spinal cord was made on the back of each rat and sutured under anaesthesia and sterile conditions. Excision was closed with 4/0 atraumatic silk suture. EGF solution was freshly prepared at 10 ng/ml dose in thilotears gel under aseptic conditions. Following the surgery, 1 ml of EGF solution was administered to wound strips one time in everyday. The animals were euthanised and wound tissues were collected on days 1, 5, 7 and 14. Thiobarbituric acid reactive substans (TBARS), glutathione (GSH), reactive nitrogen oxide species (NOx), ascorbic acid levels and superoxide dismutase activity were measured spectrophotometrically. TBARS levels decreased and NOx levels increased on day 5 after operation, and GSH levels were increased on day 14 in EGF administered group compared with untreated group. Our data showed that EGF may act like an antioxidant by scavenging toxic oxidation products in wound tissue. In addition, it may contribute healing of the wound tissue in earlier stages and suggest a potential effective role for antioxidant therapies, especially until day 5.

  16. Case of administrative dispute

    Directory of Open Access Journals (Sweden)

    Xhemazie Ibraimi


    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

  17. Intradermal administration of ATP does not mitigate tyramine-stimulated vasoconstriction in human skin (United States)

    Wingo, Jonathan E.; Brothers, R. Matthew; Coso, Juan Del


    Cutaneous vasodilation associated with whole-body heat stress occurs via withdrawal of adrenergic vasoconstriction and engagement of cholinergic “active” vasodilation, the latter of which attenuates cutaneous vasoconstrictor responsiveness. However, the precise neurotransmitter(s) responsible for this sympatholytic-like effect remain unknown. In skeletal muscle, ATP inhibits adrenergically mediated vasoconstriction. ATP also may be responsible for attenuating cutaneous vasoconstriction since it is coreleased from cholinergic neurons. The effect of ATP on cutaneous vasoconstrictor responsiveness, however, has not been investigated. Accordingly, this study tested the hypothesis that ATP inhibits adrenergically mediated cutaneous vasoconstriction. To accomplish this objective, four microdialysis probes were inserted in dorsal forearm skin of 11 healthy individuals (mean ± SD; 35 ± 11 years). Local temperature at each site was clamped at 34°C throughout the protocol. Skin blood flow was indexed by laser-Doppler flowmetry and was used to calculate cutaneous vascular conductance (CVC; laser-Doppler-derived flux/mean arterial pressure), which was normalized to peak CVC achieved with sodium nitroprusside infusion combined with local skin heating to ∼42°C. Two membranes were perfused with 30 mM ATP, while the other two membranes were flow matched via administration of 2.8 mM adenosine to serve as control sites. After achieving stable baselines, 1×10−4 M tyramine was administered at all sites, while ATP and adenosine continued to be infused at their respective sites. ATP and adenosine infusion increased CVC from baseline by 35 ± 26% CVCpeak units and by 36 ± 15% CVCpeak units, respectively (P = 0.75). Tyramine decreased CVC similarly (by about one-third) at all sites (P < 0.001 for main effect and P = 0.32 for interaction). These findings indicate that unlike in skeletal muscle, ATP does not attenuate tyramine-stimulated vasoconstriction in human skin. PMID

  18. Cutaneous Mycobacterium massiliense infection associated with cupping therapy. (United States)

    Lee, S Y; Sin, J I; Yoo, H K; Kim, T S; Sung, K Y


    Nontuberculous mycobacteria (NTM) are ubiquitous organisms that are now seen as emerging human pathogens. NTM infections are very difficult to diagnose and treat, therefore a high index of clinical suspicion is needed for diagnosis. Cutaneous NTM infections have been primarily reported associated with previous invasive procedures. We report the case of a healthy 59-year-old woman who developed recurring abdominal skin lesions caused by Mycobacterium massiliense after she underwent noninvasive cupping therapy. We identified the pathogen using a PCR assay targeting the erm(41) gene of the bacterium. The patient was treated successfully by en bloc excision and long-term antibiotic treatment. This case shows that cutaneous infection with M. massiliense may occur in an immunocompetent person without an antecedent invasive procedure.

  19. Cutaneous Vasculitis in a Patient with Antiphospholipid Antibody Syndrome. (United States)

    Sheth, Khushboo; Parke, Ann


    Antiphospholipid antibody syndrome (APS) is an acquired thrombophilia, caused by autoantibodies to anticardiolipin (aCL), or antibeta 2 glycoprotein I, or the presence of lupus anticoagulant (LA) in plasma. It is characterized by recurrent venous and/or arterial thrombi and/or pregnancy related morbidities. We present the case of a 52-year-old female with long-standing APS, who developed cutaneous vasculitis following a common cold. Most of the cutaneous manifestations of APS have been found to be thrombotic on histopathology without evidence of perivascular inflammation. Vasculitis is usually seen in APS patients with coexistent Systemic Lupus Erythematosus (SLE). However, our patient had evidence of vasculitis on skin biopsy and did not have SLE. Though rare, this is a disease process which must be considered in patients with primary APS which must be closely monitored for other vasculitic complications of APS, particularly diffuse alveolar hemorrhage.

    Sterry, W.; Pullmann, H.; Steigleder, G.K.


    To obtain information about the role of local proliferation in the pathogenesis of dermal infiltrate in malignant cutaneous lymphomas, we determined the percentage of /sup 3/H-thymidine-labeled infiltrating cells (/sup 3/H-index). A linear correlation was found between proliferative activity and clinical stage in mycosis fungoides, i.e., the /sup 3/H-index is moderately elevated in stage I and high in stage III. The /sup 3/H-index is within normal range in dermal infiltrate of Sezary syndrome, diffuse lymphocytic lymphoma, as well as in lymphocytoma benigna cutis. In parapsoriasis en plaques two groups can be distinguished: in the small plaque variant (chronic superficial dermatitis) the /sup 3/H-index is low, whereas the large-plaque variant (prereticulotic poikiloderma) shows strong proliferative activity. Thus, determination of proliferative activity seems to give new insights into the pathogenesis of dermal infiltrate in cutaneous lymphomas.

  2. Cutaneous malignant melanoma in association with mycosis fungoides. (United States)

    Evans, Alun V; Scarisbrick, Julia J; Child, F J; Acland, Katharine M; Whittaker, Sean J; Russell-Jones, Robin


    We retrospectively analyzed the first 461 cases entered into our cutaneous lymphoma database and found 285 cases of mycosis fungoides. We also identified 6 cases of malignant melanoma, all of which were found in patients with mycosis fungoides. The crude rate of melanoma in the general population in England, United Kingdom, in 1998 was 8.8/100,000 in men and 11.4/100,000 in women. The incidence of melanoma found in our cohort of patients with mycosis fungoides was far higher, and in 4 of the 6 patients cannot be explained on the basis of prior therapy. The reason for this association is unclear, but this report emphasizes the risk of second malignancies for patients with cutaneous T-cell lymphoma and melanoma.

  3. Case report of cutaneous histiocytic sarcoma: diagnostic and therapeutic dilemmas. (United States)

    Trevisan, Flávia; Xavier, Celia Antonia; Pinto, Clovis Antonio Lopes; Cattete, Fernanda Gomes; Stock, Fabíola Schauffler; Martins, Marcella Ledo


    Histiocytic sarcoma is a rare hematologic malignant neoplasia originating from histiocytic or dendritic cell clones. The lesions may be in nodal or extranodal sites, most commonly in the gastrointestinal tract. A small number of cases presents as unique cutaneous lesions. The definitive diagnosis is made by positivity for the immunohistochemical markers CD163, CD68, CD4 and lysozyme. The treatment is controversial, often with combined systemic chemotherapy. This is a case of cutaneous histiocytic sarcoma in an 82-year-old patient presenting two nodular lesions in the breast and right arm which were treated with simple excision and multidisciplinary follow-up, avoiding aggressive management and exhaustive investigations. Although most studies report aggressive evolution, the patient had good and stable clinical status during the twelve-month follow-up period.

  5. Cutaneous sporotrichosis as an occupational disease: Case report

    Directory of Open Access Journals (Sweden)

    César Bimbi


    Full Text Available Subcutaneous mycoses are not rare in Latin America. In Brazil, sporotrichosis was once almost exclusively found in rural areas, but in recent years it changed its profile and has been more frequent among urban adults. Cutaneous sporotrichosis is acquired from saprophytic dimorphic fungus Sporothrix schenckii usually found in soil, vegetation, and especially decaying organic matter in tropical, subtropical, and humid environments through cutaneous inoculation. The fungus abundantly grows on dead wood. Sporotrichosis is a health hazard present in florists, gardeners and other urban professions in contact with plants and the infection is increasingly seen as an occupational disease. The patient had been hurt in the finger by a thorn of Bouganvillea tree and a primary ulcer started.

  6. Geographical distribution of cutaneous leishmaniasis and sand flies in Pakistan. (United States)

    Shakila, Ashraf; Bilqees, Fatima Mujib; Salim, Azra; Moinuddin, Moinuddin


    Cutaneous leishmaniasis is found in all the four provinces of Pakistan; these are NWFP, Balochistan, Sindh and Punjab. In Balochistan the areas from where the patients came are Uthal, Quetta and Ormara. The highest number of patients came from Quetta and least from Ormara. The patients included in this study were from the Mangopir and Chakewara, areas of Karachi. The infection is endemic in this country and the recent epidemics in the Dadu District and Nawabshah indicate its importance in the locality. The sand fly vector is found in all four provinces of Pakistan that are listed here. It is quite obvious that presence of leishmaniasis indicates the presence of sand flies and cutaneous leishmaniasis is more common.

  7. Socioeconomic and Ethnic Disparities in Periocular Cutaneous Malignancies. (United States)

    Broadbent, Talmage; Bingham, Brian; Mawn, Louise A


    Cutaneous malignancies make up the majority of periocular tumors diagnosed and treated by ophthalmologists. In this review, we examine literature regarding ethnic and socioeconomic disparities in incidence and clinical outcomes of the three most common cutaneous periocular tumors: basal cell carcinoma, squamous cell carcinoma, and melanoma. In all three tumor types, the literature shows an increased incidence among two groups: those with lightly pigmented skin and those of higher socioeconomic status. While incidence is high in these groups, clinical outcomes for these patients tend to be good. Those with lower socioeconomic status and ethnic minorities, on the other hand, have a low incidence but are more likely to have poor clinical outcomes. These disparities are likely the result of both biologic and behavioral differences between patients and could provide opportunities for intervention to change risk perception and improve outcomes.

    Objective To identify Mycobacterium marinum (M. marinum) inducing misdiagnosis and treatment failure.Methods The lesional specimen of patient with cutaneous M. marinum were cultivated on Lwenstein-Jensen medium. The isolate was identified by biochemical tests and polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis of the hsp65 gene.Results Smooth and non-pigmented colonies were noted after incubation at 32 ℃ for 2 weeks. The isolate was acid-fast bacilli and confirmed as M. marinum by biochemical tests and PCR-RFLP.Conclusion For a correct diagnosis of cutaneous M. marinum infection, it is crucial for clinicians to have a high index of suspicion, obtain the history of exposure and trauma and understand growth characteristics of the organism. Compared with conventional biochemical techniques, PCR-RFLP analysis is a more rapid, accurate and reliable method for mycobacterial identification to species level.

  10. [Management of cutaneous leishmaniasis in adults and children]. (United States)

    Minodier, P; Noël, G; Blanc, P; Uters, M; Retornaz, K; Garnier, J M


    Cutaneous leishmaniasis can present a variety of clinical features and courses. The causative Leishmania species is an important prognostic factor in immunocompetent patients. Local treatment modalities including topical paromomycin, cryotherapy, localized controlled heat, carbon dioxide laser therapy, or intralesional meglumine antimoniate can be effective against Leishmania major or Leishmania tropica. Oral fluconazole may be a second-line treatment. Parenteral antimonials are useful for persistent or recurrent Old World leishmaniasis. For New World leishmaniasis, parenteral antimonials represent the first-line treatment in all forms except those caused by Leishmania guyanensis in which pentamidine is preferable. Liposomal amphotericin B appears to be effective for treatment of cutaneous leishmaniasis but further study will be needed. Results using oral Miltefosine are promising against Indian kala-azar (Leishmania donovani) but disappointing against South American leishmaniasis.

  11. Reactive Oxygen Species and Nitric Oxide in Cutaneous Leishmaniasis

    Directory of Open Access Journals (Sweden)

    Maria Fátima Horta


    Full Text Available Cutaneous leishmaniasis affects millions of people around the world. Several species of Leishmania infect mouse strains, and murine models closely reproduce the cutaneous lesions caused by the parasite in humans. Mouse models have enabled studies on the pathogenesis and effector mechanisms of host resistance to infection. Here, we review the role of nitric oxide (NO, reactive oxygen species (ROS, and peroxynitrite (ONOO− in the control of parasites by macrophages, which are both the host cells and the effector cells. We also discuss the role of neutrophil-derived oxygen and nitrogen reactive species during infection with Leishmania. We emphasize the role of these cells in the outcome of leishmaniasis early after infection, before the adaptive Th-cell immune response.

  12. 2-chlorodeoxyadenosine treatment for cutaneous T-cell lymphoma

    Malgorzata Sokolowska Wojdylo


    Full Text Available The primary cutaneous lymphomas are often indolent but difficult to treat. In the early stages psoralen and ultraviolet-A therapy is the standard treatment whereas at the tumor stage chemotherapy (e.g. pegylated doxorubicin is often used for debulking. The purine analog 2-chlorodeoxyadenosine (2CdA acts in non-Hodgkin’s lymphoma and has been used in our center for the treatment of advanced primary cutaneous T-cell lymphomas (CTCL. Here, we report on the efficacy and side effects of 2CdA in six patients with CTCL. One patient died owing to myelosuppression. Partial responses were seen in four cases but full remission was observed in only one case. We concluded that 2CdA has a limited usefulness in the management of advanced CTCL.

  13. Localized cutaneous mucinosis associated with multiple myeloma: A rare presentation

    Parvaiz Anwar Rather


    Full Text Available Lichen myxoedematosus (LM, a form of primary cutaneous mucinosis, may present either as localized less severe form called papular mucinosis or diffuse more severe form called scleromyxoedema. The diffuse form is almost always associated with monoclonal gammopathy, whereas localized form is not. We report an atypical case of localized form of LM associated with multiple myeloma in a 66-year-old male, who presented with asymptomatic waxy papular eruption on extremities, which on histopathological examination confirmed the diagnosis of cutaneous mucinosis. After initially being put on steroids and hydroxychloroquine with minimal improvement, patient subsequently presented with encephalopathy and on evaluation revealed hypernatremia, hypercalcemia, hypergammaglobulinemia, reversal of albumin-globulin (A/G ratio, azotemia, and lytic lesions in skull X-ray. Bone marrow aspiration and biopsy confirmed multiple myeloma. Patient was successfully treated with standard treatment regimen for multiple myeloma with bortezumib and dexamethasone and his skin lesions subsided completely.

    Coutinho, Inês; Rocha, Sónia; Ferreira, Maria Eugénia; Vieira, Ricardo; Cordeiro, Margarida Robalo; Reis, José Pedro


    Cutaneous loxoscelism is an exceptional diagnosis in Portugal, regardless of the documented presence of Loxosceles rufescens.We report a 33-year old female patient presenting to our clinic after having visualized a bite from a spider in the inner aspect of the right thigh. Afterwards, she developed a warm, painful erythematous plaque, progressing to skin necrosis and torpid ulcer formation. Considering the failure of conservative measures, surgical debridement of the ulcer followed by repair using an O-Z plasty achieved good functional outcome. Definite diagnosis of cutaneous loxoscelism may be difficult since it relies on the visualization of the bite, capture of the spider for identification and typical clinical features. This case meets several criteria that allow the establishment of a causative link between spider bite and dermonecrosis. It is, to the best of our knowledge, the first diagnosis of loxoscelism reported in Portugal.

  15. Cutaneous Paecilomyces lilacinus infections in immunocompromised and immunocompetent patients

    Directory of Open Access Journals (Sweden)

    Shahindokht Bassiri-Jahromi


    Full Text Available Paecilomyces is a genus of saprophytic fungus that has been associated, in rare instances, with human disease. We report two cases in which Paecilomyces lilacinus was isolated from cutaneous and subcutaneous lesions in an immunocompromised and an immunocompetent host. The first case was a subcutaneous infection due to P. lilacinus in a patient with a renal transplant and diabetes mellitus. The second case was an immunocompetent young woman who developed a cutaneous infection, with no identified predisposing factors. A biopsy from each patient provided an initial diagnosis of fungal elements in the tissues under examination and multiple positive fungal cultures were obtained from the tissue biopsy samples. Both microscopic and macroscopic examinations of the biopsy revealed the presence of P. lilacinus. Each of the two cases was successfully treated with oral ketoconazole (200 mg/day and itraconazole. We also review previously reported cases in which the clinical history and response to therapy were noted.

    Wing-Fu Lai; Parco M Siu


    MicroRNAs (miRNAs) have emerged as key post-transcriptional regulators of gene expression, and have displayed important roles in areas spanning from embryonic development to skin physiology. Despite this, till now little is known about the significance of miRNAs in cutaneous wound healing. In this mini-review, we discuss the existing evidence on the roles of miRNAs in physiological processes relevant to cutaneous wound healing, followed by a highlight of the prospects and challenges of future development of miRNA-based wound therapies. With existing technologies of nucleic acid transfer and miRNA modulation, it is anticipated that once the roles of miRNAs in wound healing have been clarified, there will be a vast new vista of opportunities brought up for development of miRNA-targeted therapies for wound care.

    @@ Infections caused by opportunistic organisms which have been known as etiologic agents of disease become more and more frequent.Aspergillus spp. is one of the agents. Fungi of aspergillus genus are widely distributed in nature, particularly in the soil and in the decomposed vegetation. They are frequent opportunist pathogens in immunocompromised patients. The most frequent causative organisms that cause cutaneous aspergillosis are A.fumigatus and A.flavus.1-3 In this report, we present a case of primary cutaneous aspergillosis manifested by ulceration of the shank due to A. flavus. The patient had no deficiency of immunological status and severe disease associated with fungal infection. Excellent response was shown to anti-fungal therapy.

  18. Multiple cutaneous metastases in laryngeal carcinoma: A rare occurrence

    Directory of Open Access Journals (Sweden)

    Kishore Das


    Full Text Available Metastasis to the skin in laryngeal squamous cell carcinoma is an extremely rare occurrence. We report a case of multiple cutaneous metastases in the follow-up of a 60-year-old male with squamous carcinoma of the vocal cords that were treated with surgery and radiotherapy. The patient presented with multiple painful skin nodules at 3 months following the completion of treatment. Clinically the skin nodules mimicked an inflammatory skin lesion. The diagnosis of metastatic skin lesions was made by cytological examination. Appearance of new painful skin lesions soon after the completion of treatment in patients treated for squamous carcinoma of the larynx should warrant a clinical suspicion of cutaneous metastases.

    Sabrina Sisto Alessi


    Full Text Available INTRODUCTION: There are various approaches to the treatment of cutaneous tumors; one of them is treatment with imiquimod, a synthetic toll-like receptor agonist with a low molecular weight that offers a topical, noninvasive, and non-surgical therapeutic option. The main objective of our study was to provide data on 89 patients who used a 5% imiquimod cream for the treatment of cutaneous tumors at the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas from 2003 to 2008. MATERIALS AND METHODS: Here, we present our experience in the treatment of 123 cutaneous tumors of various types, including basal cell carcinoma (BCC, squamous cell carcinoma (SCC, Bowen's disease, erythroplasia of Queyrat, Paget's disease, and trichoepithelioma, with 5% imiquimod cream from 2003 to 2008 in the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas. Patients were divided into two separate groups according to their diagnosis and comorbidities; these comorbidities included epidermodysplasia verruciformis, xeroderma pigmentosum, albinism, basal cell nevus syndrome, Brooke-Spiegler syndrome, HIV, chronic lymphocytic leukemia, B-cell lymphoma, and kidney transplantation. Treatment duration, response to imiquimod, follow-up, recurrence, and local and systemic reactions associated with use of the drug were analyzed. Epidemiological data were obtained and cure rates were calculated. RESULTS: The ratio of women to men was 1.28:1, and the mean age was 63.1 years. Tumors were located mainly on the face, back, trunk, and legs. For patients with comorbidities, the overall cure rate was 38%. These specific patients demonstrated cure rates of 83.5% for superficial BCC and 50% for Bowen's disease. Aggressive BCC and superficial and nodular BCC did not present a good response to treatment. Trichoepitheliomas and nodular BCC showed a partial response, and erythroplasia of Queyrat showed a complete response. For patients without

    Shaun Previn Appaduray


    Conclusion: CVJ TB may be treated solely with anti-TB therapy and immobilization to good effect if there is no gross instability or neurological deficit. Similarly, cutaneous TB responds well to standard anti- TB therapy. Our experience suggests that co-existing tuberculous lesions in the CVJ and skin can be simultaneously managed with standard therapy without significant alterations to treatment regimes or prognosis.

    Objective: To describe and compare the epidemiological features of anthroponotic cutaneous leishmaniasis (ACL) caused by Leishmania tropica, and zoonotic cutaneous leishmaniasis (ZCL) due to Leishmania major in Morocco. Methods: We performed a retrospective study of ZCL and ACL cases reported during the last ten years in Morocco (2004–2013). Epidemiological data were analyzed by using Pearson's correlation method as well as Tukey test and digital maps were produced for incidence repartition calculated by using ArcMap GIS version 10. Results: A total of 41 656 cases of cutaneous leishmaniasis were notified between 2004 and 2013 in Morocco. The mean incidence was 139 cases/100 000 population/10 years and it was significantly higher in 2010. In the spatial context, ACL form was the most common in Morocco, while ZCL was the most important in terms of the number of reported cases. For both forms, the highest incidence occurred in females and children (0–14 years). When analyzed according to the number of cases in each province, Errachidia (8 728 cases) and Azilal (3 523 cases) were the most affected by ZCL and ACL, respectively, while the highest incidence was noted in Zagora (231 cases/100 000 pop-ulation/10 years) and in Chichaoua (97 cases/100 000 population/10 years), for ZCL and ACL, respectively. Maps of incidence repartition were performed to identify the risk area of ZCL and ACL. Conclusions: ZCL and ACL are still major health problems in Morocco. We highlight the spatiotemporal change of cutaneous leishmaniasis incidence through the country during the last ten years and we underline the correlation between ZCL incidence and the percentage of rural population in Morocco.

    Fernández Romero, D; Di Marco, P; Malbrán, A


    Hereditary angioedema is a rare autosomal dominant disease characterized by recurrent episodes of acute edema affecting the skin and the respiratory and digestive tracts. Acute edema blisters or hydro-static bullae develop after rapid accumulation of interstitial fluid usually associated to cardiac insufficiency. Lesions contain sterile fluid and break up easily resolving without scars. Blisters disappear when fluid accumulation resolves. We describe a patient developing recurrent acute edema blisters as a consequence of cutaneous hereditary angioedema attacks.

  14. GLUT-1 Expression in Cutaneous Basal and Squamous Cell Carcinomas. (United States)

    Abdou, Asmaa Gaber; Eldien, Marwa Mohammad Serag; Elsakka, Daliah


    Glucose uptake is a key regulating step in glucose metabolism and is mediated by facilitative glucose transporters (GLUTs), and GLUT-1 is the predominant glucose transporter in many types of human cells. Cutaneous basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) represent the most common skin cancer in Egypt. The present study aimed at evaluation of the pattern and distribution of GLUT-1 in cutaneous BCC (16 cases) and SCC (16 cases) by means of immunohistochemistry. GLUT-1 was expressed in all SCC (100%) and in 62.5% of BCC. Membranous pattern of GLUT-1 was seen in 62.5% of SCC and 31.25% of BCC. Positivity (P = .02) and percentage (P = .000) of GLUT-1 expression were in favor of SCC in comparison to BCC. The high percentage of GLUT-1 expression was associated with high grade in SCC (P = .03). The immunoreactivity for GLUT-1 was more in the periphery of malignant nests of SCC while it was more in the center of BCC nests. GLUT-1 is overexpressed in cutaneous non-melanoma skin cancer. Its expression in SCC is related to differentiation status, and its expression in BCC is intimately associated with squamous metaplastic areas.

  15. Alternating-pulse iontophoresis for targeted cutaneous anesthesia (United States)

    Meyer, Peter F.; Oddsson, Lars I E.


    In studies of sensory contributions to motor control, it may be advantageous to temporarily reduce the sensitivity of specific sensory systems. This article details a method for non-invasively inducing cutaneous anesthesia, leaving proprioceptive and motor functions intact. This method, called alternating-pulse iontophoresis, differs from conventional direct-current (DC) iontophoretic drug delivery in that adjacent drug delivery electrodes are stimulated out-of-phase. The total current delivered at any instant is then less than that produced during a comparable DC application, while the uniformity of drug delivery is expected to improve. Effective delivery of local anesthetics to the cutaneous foot soles by alternating-pulse iontophoresis was demonstrated using cutaneous pressure sensory threshold levels (STL's) assessed with Semmes-Weinstein monofilaments (arbitrary units of perceived force, or a.u.). Thirteen of 16 healthy subjects achieved a level of anesthesia greater than or equal to that normally associated with clinical peripheral sensory neuropathy. Average STL's measured prior to the anesthesia procedure were 4.00 a.u. ( approximately 10 mN). Immediately following the procedure, STL's were elevated to an average of 5.40 a.u. ( approximately 246 mN) and averaged 4.97 a.u. ( approximately 92 mN) after 50 min of standing. A number of research and clinical applications for this technique are suggested.

  16. Cutaneous chemical burns in children - a comparative study. (United States)

    Hardwicke, Joseph; Bechar, Janak; Bella, Husam; Moiemen, Naiem


    Exposure to chemicals is an unusual causation of cutaneous burns in children. The aim of this study is to look at childhood chemical burns and compare this to adult chemical burns from the same population. A total of 2054 patients were referred to the pediatric burns unit during the study period. This included 24 cutaneous chemical burns, equating to an incidence of 1.1%. Over half of the injuries occurred in the domestic setting. The mean total body surface area (TBSA) affected was 1.9%. When compared to a cohort of adult patients from the same population with cutaneous chemical burns, the TBSA affected was identical (1.9%) but distribution favored the buttock and perineum in children, rather than the distal lower limb in adults. Children presented earlier, had lower rates of surgical intervention and had a shorter length of stay in hospital (p Chemical burns in children are rare, but are becoming more common in our region. It is important to be aware of the characteristic distribution, etiology and need to identify children at risk of child protection issues.

    Full Text Available Skin is an organ that has a primary function of tactile receptivity and reacts to both external and internal emotional stimuli. Dermatological practice certainly embeds a psychosomatic dimension. A relationship between psychological factors and skin diseases has long been hypothesized. AIMS AND OBJECTIVES The aim of present study is to evaluate the prevalence of cutaneous manifestations in patients with psychiatric disorder. MATERIALS AND METHODS Twenty five psychiatric in-patients admitted in the psychiatry ward of a Tertiary Care Hospital were examined for the presence of cutaneous manifestation over a period of 6 months. Appropriate laboratory investigations such as scraping for Acarus, skin biopsy etc. were performed wherever required. The observations were noted. RESULTS The commonest cutaneous manifestations seen in this study were (i Parasitic infestations like scabies (20%, pediculosis capitis (16%, (ii Xerosis (28 %, (iii Prurigo nodularis (4%, (iv Lichen simplex chronicus (4%, (v Venereophobia (4% and (vi Delusion of parasitosis (4%. CONCLUSION A high incidence of parasitic infestations was noted in our study. The healthcare personnel should be sensitized on the significance of such parasitic infestations in institutionalized patients and the importance of early detection and treatment.

  18. Hemorrhagic bullous dermatosis: a rare heparin-induced cutaneous manifestation. (United States)

    Govind, Bhuvanesh; Gnass, Esteban; Merli, Geno; Eraso, Luis


    Heparin is one of the most widely prescribed medications. Cutaneous reactions distant to the injection site are rare and under-reported in the literature. We present an elderly man with history of CNS lymphoma who underwent treatment of a deep venous thrombosis with enoxaparin and subsequently developed well demarcated bullous lesions within days of heparin initiation. The exact pathophysiology is not well understood. Hemorrhagic bullous dermatosis is a rare cutaneous reaction that is temporally associated with the initiation of heparin products. The handful of cases thus far suggest that regression of these seemingly benign lesions may or may not be associated with dose reduction or discontinuation of heparin products and typically occur within a few weeks. Elderly age appears to be one potential risk factor for development of these rare asymptomatic lesions. Malignancy may have some contributing factor and differentiation between this rare cutaneous manifestation from heparin products and other dermatological findings in patients with malignancy is key. Because of the asymptomatic and self-limiting nature of hemorrhagic bullous dermatoses in the setting of heparin product use, we presume that the reported incidence does not reflect true clinical practice.

    Full Text Available CONTEXT: Anthrax is a very rare disease in Europe and the United States. AIM: A case of cutaneous anthrax of the hand with a wide skin defect is presented and some clinical observations highlighted. CASE REPORT: A 56-year-old male patient with cutaneous anthrax attended our infectious diseases department with a swelling up to the upper arm. An urgent fasciotomy was undertaken with a diagnosis of compartment syndrome. A black eschar had formed on the dorsal surface of the hand. A superficial tangential escharectomy was performed. RESULTS: Viable fibrous tissue, about 4 to 5 mm in thickness over the extensor tendons, was found under the eschar. At the postoperative 2-year follow-up, remarkable healing was observed via skin grafting. CONCLUSIONS: Hand surgeons should be cautious against the compartment syndrome that may accompany cutaneous anthrax of the hand. A consistent viable fibrous tissue can be found below the eschar. The mechanism for the involvement of the hand dorsum needs further concern.

    Purpose: to describe an experimental model of cutaneous radiation injury in rabbits. Methods: on this study eight six-month-old New Zealand male rabbits, with an average weight of 2.5kg were used. They were distributed in four groups (n=2 per group). The control group did not receive radiotherapy and the others received one radiotherapy session of 2000, 3000 and 4500 cGy, respectively. Photographic analysis and histopathological evaluation of the irradiated areas were carried out. Results: after 30 days, the animals from the control group had all their hair grown. In spite of that, the animals from group 2000 cGy had a 60-day alopecia and from group 3000 cGy, a 90-day alopecia. After the 30th day, the 3000cGy group demonstrated 90-day cutaneous radiation injuries, graded 3 and 4. One of the animals from group 4500 cGy died on the 7th day with visceral necrosis. The other from the same group had total skin necrosis. A progressive reduction of glands and blood vessels count and an increase on collagen deposition was observed. Conclusion: The proposed experimental model is reproducible. This study suggests that the dosage 4500cGy is excessive and the 3000 cGy is the most effective for this experimental model of cutaneous radiation injury in rabbits. (author)

  1. [Cutaneous leishmaniasis in France: towards the end of injectable therapy?]. (United States)

    Buffet, P A; Morizot, G


    Today no drug likely to be efficient on the majority of human-infecting species, well tolerated, and easy to administer is available for the treatment of human cutaneous leishmaniasis. But recent progress has been made. Efficient against visceral leishmaniasis, orally administered miltefosine may supplant pentavalent antimonials for the treatment of cutaneous leishmaniasis acquired in the New World. Right now, the reference treatment is still parenteral pentavalent antimonials 20 mg Sbv/kg/d for a duration that may probably be reduced from 20 to 10 days. The benefit/risk ratio of pentamidine still compares well with that of pentavalent antimonials for the treatment of lesions due to species belonging to the L. panamensis/L. guyanensis/L. shawi group. Pentamidine, which is easier to handle than antimonials, remains the reference treatment for cases from areas where these species predominate. Oral fluconazole is an improvement, readily available for cases from L. major foci. If its efficacy is confirmed in other foci and against other species, mechanisms will have to be implemented to make this therapeutic improvement affordable to poor patients in endemic countries. The development of an efficient and well tolerated topical treatment is still warranted. A new formulation of aminosidine is currently under evaluation. One can hope that the treatment of cutaneous leishmaniasis will soon become simpler, both for patients and doctors. For the benefits of this simplification to be rapidly affordable to all patients, the pharmaceutical and clinical research outlay must be maintained.

    Background Tuberous sclerosis (TS) is an autosomal dominant disorder with a significant range of clinical expressions. The involvement of vital organs, such as the brain, kidney, heart and lung is the main cause of death in patients with TS. The aim of this study is to summarize the charateristic cutaneous features and common extracutaneous involvement of TS, which are helpful to the early detection of visceral involvement.Methods The analyzed clinical data from 78 patients with TS included those from detailed history, physical and dermatological examination, cranial computed tomography (CT) and magnetic resonance imaging (MRI), abdominal ultrasonography, chest roentgenography, hand and foot X-ray and ophthalmologic examination. Results The skin, brain and kidney were involved frequently in TS patients. Hypomelanotic macules were the most common and earliest cutaneous lesions. Their number was more than 3 in 81.5% of the patients. They were followed by facial angiofibromas and Shangreen's patch in a decreasing frequency. Forehead plaque, facial angiofibromas and Shagreen's patch appeared in patients at mean age of 2.6, 6.0 and 8.1 years respectively. Cranial CT showed a high positive rate in TS patients.Conclusions Cutaneous features of TS are helpful in the early diagnosis of the disease. Hypomelanotic macules are especially important for patients with epilepsy or babies whose number of hypomelanotic malues is more than 3. Cranial CT is of great value in the diagnosis of TS. The involvement of visceral organs such as the brain and kidney should be examined in TS patients

  3. GNA11 Mutation in a Patient With Cutaneous Origin Melanoma (United States)

    Patel, Sapna P.; Kim, Dae Won; Lacey, Carol L.; Hwu, Patrick


    Abstract The rapid advances in the molecular biology and genetics have improved the understanding of molecular pathogenesis of v-Raf murine sarcoma viral oncogene homolog B (BRAF), feline sarcoma viral oncogene v-kit (KIT), and neuroblastoma v-Ras oncogene homolog (NRAS) mutant melanomas with the subsequent development of targeted therapeutic agents. However, only limited data are available for melanoma harboring other somatic than BRAF, KIT, and NRAS mutations. Mutations in guanine nucleotide-binding protein Q polypeptide (GNAQ) and guanine nucleotide-binding protein alpha-11 (GNA11), alpha subunits of heterotrimeric G proteins, constitutively activate mitogen-activated protein kinase (MAPK) pathway in uveal melanoma. However, there are no reports of GNA11 mutations in cutaneous melanomas. A 48-year-old woman was diagnosed with cutaneous nodular melanoma on the left scalp. Mutation analysis of the tumor revealed a GNA11 Q209L mutation. There was no evidence of uveal melanoma or malignant blue nevus in ophthalmologic exam, imaging studies, and pathology review. To our knowledge, this is the first case report to demonstrate cutaneous origin melanoma harboring a GNA11 Q209L mutation. PMID:26825879

  4. The "mystery" of cutaneous sarcoidosis: facts and controversies. (United States)

    The reason why the cutaneous form of sarcoidosis is well known in the literature is because of its spectrum of manifestations granting it the fame of a Great Imitator. The mystery shrouding the pathogenesis of this rare cutaneous disease is still there (in spite of the fundamental progress of the various diagnostic methods in current day medicine). The production of the morphological substrate - the epithelioid cell granuloma - which is considered to be characteristic of skin sarcoidosis, could, however, also be the end result of a reaction to i) various specific infectious agents such as Leishmaniasis cutis, coccidioidomycosis, etc., ii) certain residual bacterial or other mycobacterial antigens which, at the moment of setting the diagnosis are - by definition - non-infectious but still immunogenic, as well as iii) different tumor antigens in lesional tissue or other location. Often, differentiating between sarcodiosis and a sarcoid-like reaction, based on the updated criteria for cutaneous sarcoidosis, is problematic to downright impossible. A future characterization of the genetic signature of the two conditions, as well as the implementation of additional mandatory panels for i) the identification of certain infectious or ii) non-infectious but immunogenic and iii) tumor antigens in the epithelioid cell granuloma (or in another location in the organism), could be a considerable contribution to the process of differentiating between the two above-mentioned conditions. This will create conditions for greater accuracy when setting the subsequent therapeutic approaches.

    Full Text Available Cardiac conduction disorders following oral ingestion of Oleander plant materials were documented earlier. Transcutaneous absorption of yellow oleander (Thevetia peruviana leaf extract applied over non intact skin (raw wound resulting in reversible cardiac conduction disorder observed in four healthy males who were free from any other systemic or electrolyte or metabolic disorders or exposure to pesticide or toxins is reported for the first time. Their hematological, biochemical, clinical, and echocardiogram status were within normal limits and free of any abnormalities. One among the four, presented for weakness and breathlessness (class II. He had bradycardia with Mobitz II block and hypotension without any other demonstrable localizing signs. The other three were identified in the community and without any symptoms. However, their ECG revealed bradycardia with Mobitz I block in two and complete heart block in the other. All of the four recovered well without any untoward events. Hence, it is suggested that physicians and practitioners have to elicit history and route of administration of unconventional therapy, whenever they are confronted with clinical challenges and during medical emergencies before embarking final decision.

    Narváez Garcia, Francisco Javier; Pascual, María; López de Recalde, Mercè; Juarez, Pablo; Morales-Ivorra, Isabel; Notario, Jaime; Jucglà, Anna; Nolla, Joan M.


    Abstract The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported. These atypical skin eruptions often present in addition to the typical evanescent rash but may also be the only skin manifestation, resulting in delayed diagnosis because of under-recognition. In this study, we present 3 new cases of AOSD with atypical cutaneous manifestations diagnosed during a 30-year period in our department and review 78 additional cases previously reported (PubMed 1990–2016). These 81 patients form the basis of the present analysis. The overall prevalence of atypical cutaneous manifestations in our AOSD population was 14%. These manifestations may appear at any time over the course of the disease, and usually occur in patients who have persistent and severe disease, with a considerable frequency of clinical complications (23%), including serositis, myopericarditis, lung involvement, abdominal pain, neurologic involvement, and reactive hemophagocytic syndrome. The most representative and frequent lesion among the nonclassical skin rashes is the development of persistent pruritic papules and/or plaques. Interestingly, these lesions show a distinctive histological pattern. Other, less frequently observed lesions include urticaria and urticaria-like eruptions, generalized or widespread non-pruritic persistent erythema, vesiculopustular eruptions, a widespread peau d’orange appearance of the skin, and edema of the eyelids mimicking dermatomyositis without any accompanying skin lesion. The great majority of these patients required medium or high doses of glucocorticoids (including intravenous methylprednisolone pulse therapy in some cases) and, in nearly 40%, a more potent or maintenance immunotherapy

    Full Text Available Background : In India, indigenous cases of cutaneous leishmaniasis (CL are mainly confined to the northwestern region. But now, more and more case reports are coming in from other parts of India. In January 2009, a 26-year-old lady residing in a forest area in Thiruvananthapuram district of Kerala State presented with bluish red nodules on her upper extremities, of six months duration, which was clinically more in favor of cutaneous leishmaniasis. She had never gone out of the district of Thiruvananthapuram in her life. Aim : To investigate whether the patient hails from a new endemic focus of cutaneous leishmaniasis. Setting and Design : An epidemiological investigation in the form of a survey was carried out in March 2009 by a multidisciplinary team among 63 persons residing in the Mele Aamala and Aayiramkala forest tribal settlements in Kuttichal Panchayat of Thiruvananthapuram district. Material and Methods : History taking and clinical examination of 38 persons in the area with special consideration to skin lesions was undertaken. Microbiological and histopathological examination of the skin lesions was done. Breeding places of sand fly and possible reservoirs of Leishmania were also simultaneously investigated. Statistical analysis used : The data obtained was tabulated as frequency and percentage. Chi-square test was done to find out the statistical significance of differences in distributions. Results : Out of the 38 persons examined, active lesions were found in 12 persons and six had healed lesions. Tissue samples were obtained from seven out of the 12 suspected cases. Four of them showed Leishman Donovan (LD bodies in tissue smears. Out of the cultures taken from three patients, one showed promastigote forms in Novy McNeal Nicolle (NNN medium. Histopathological study was done in five patients and two patients had LD bodies, one had epithelioid cell granuloma and the other two had mixed infiltrate with predominantly macrophages. All

    Patel, Atiyah; Mudenda, Victor; Lakhi, Shabir; Ngalamika, Owen


    Sporotrichosis is a subacute or chronic granulomatous mycosis caused by fungus of the Sporothrix schenckii complex. It is considered to be a rare condition in most parts of the world. It mostly causes cutaneous infection but can also cause multisystemic disease. Unlike most deep cutaneous mycoses which have a primary pulmonary focus, it is usually caused by direct inoculation of the fungus into the skin causing a classical linear, lymphocutaneous nodular eruption. However, atypical presentations of the condition can occur especially in immunosuppressed individuals. We report the case of a severely immunosuppressed female who presented with disseminated cutaneous sporotrichosis which was initially diagnosed and treated as disseminated cutaneous Kaposi's sarcoma.

    Full Text Available Aim. Article presents the current data on the clinical and epidemiological issue of leishmaniasis. Methods and results. Leishmaniasis is endemic disease in 88 countries, mainly in tropical and subtropical climates. Probability of importation of American cutaneous leishmaniasis in our country is practically zero, but, given the rarity of this disease, we present own clinical observation of imported cutaneous leishmaniasis in Zaporozhye. At the beginning of the third millennium has greatly increased the urgency of tropical parasitic diseases, including leishmaniasis. According to WHO, the world's 14 million people are infected each year there is about 2 million new cases and about 350 million live in areas at risk. Leishmaniasis - a group of vector-borne protozoal disease in humans and animals characterized by lesions of the internal organs (visceral leishmaniasis or the skin and mucous membranes (cutaneous leishmaniasis, which is the vector mosquitoes. We present their own clinical observations of American cutaneous leishmaniasis imported. Patient S., 41 years was hospitalized in Zaporozhye Regional Clinical Hospital infectious on 07.17.2013, with suspected cutaneous leishmaniasis. From the history of the disease is known that for the first time in February 2013 the patient have got relative to blade area redness and bump that appeared above the skin, and had a magnitude of 2,3 mm brownish-red. To the doctor the patient has not addressed. After 1,5-2 months bump grew and he began to stand out ichor, which dries and formed a crust on top of the hump.

    Full Text Available This article begins with an analysis of the development of administrative justice in Poland over the last centuries. In particular, the author examines administrative jurisdiction before 1918, when Poland regained its independence, the period of the Duchy of Warsaw, the Kingdom of Poland, and the practice on Polish territory under Austrian and Prussian control. The author then moves to modern law by presenting the judicial system in Poland in general, especially the differences between the separate systems of general courts and administrative courts, and analyses the jurisdiction of voivodship (regional administrative courts, and the basic principles of judicial and administrative proceedings. The focus of study is mainly devoted to judicial and administrative procedure, rather than an administrative process of citizens before administrative authorities regulated in a separate Code of Administrative Procedure. The article describes the role of the judge (pointing out the differences between the active role of first instance judges and the limited capabilities of the judges of the appeal and the powers of the Supreme Court, in particular its power to adopt resolutions, which has agreat importance for the unification of the jurisprudence. A brief analysis is given to class actions, which in the Polish legal system are inadmissible in court and administrative proceedings. The articles provides a statistical cross-section illustrating the role of administrative jurisdiction. The author concludes with observations pointing up the progress of administrative jurisdiction in Poland, not only in the legal sense, but also in the cultural sense.

    Full Text Available Context : An epidemic of chikungunya disease occurred in India during late 2005 through 2006 affecting nearly 1,400,000 people. Aim : To study the cutaneous manifestations in suspected cases of chikungunya disease. Settings and Design : Patients who attended our outpatient departments from January 2006 to September 2006 were prospectively included if they had symptoms of chikungunya disease according to the ′case definition′ of the National Institute of Communicable Diseases, Directorate General of Health Services, Government of India. The criteria were an acute illness characterized by the sudden onset of fever and several symptoms such as joint pain, headache, backache, photophobia, and eruption during an epidemic of chikungunya fever in the absence of confirmatory serological tests. Materials and Methods : A total of 115 patients (65 men and 50 women who satisfied the above criteria were enrolled for the study. Results : An erythematous maculopapular rash subsiding without any sequelae in 3-4 days was the most common cutaneous finding in our patients. Genital ulcers distributed predominantly over the scrotum and base of the penile shaft in men and labia majora in women were the second most common manifestation. Other manifestations included tenderness/edema of hands and feet, grouped hyperpigmented macules over the nose and cheeks, fixed drug eruptions, erythema nodosum, erythema multiformae, generalized urticarial eruptions, and flare up of pre-existing psoriasis and lichen planus. Conclusions : To conclude, a plethora of cutaneous manifestations were noted in suspected cases of chikungunya disease. Genital ulcers, to the best of our knowledge, have not been reported during the earlier epidemics but have been reported by others during the present one.

  2. Treatment of New World cutaneous and mucosal leishmaniases. (United States)

    Berman, J D


    The most extensive investigations of treatment of New World cutaneous leishmaniasis have been performed against L. panamensis disease in Colombia, and the relative value of regimens shown there may be instructive for disease from other areas. In Colombia, a 90-95% cure rate was achieved with three different drug regimens: The standard regimen of pentavalent antimony (20 mg/ kg/day for 20 days parenterally) A short course of pentamidine (3 mg/kg every other day for four injections intramuscularly The marketed combination of topical paromomycin (15%)-MBCl (12%) for 10 days, plus antimony (20 mg/kg/day parenterally) for 7 days. My view is that all these regimens could be chosen as first-line therapy for cutaneous disease in Colombia. The antimony regimen has the advantage of established use; the disadvantages are cost, requirement for injections each day for 20 days, and considerable morbidity in the last two weeks of therapy. The pentamidine regimen has the advantage of a short time course; the disadvantages are lack of experience with this new regimen and frequent, although moderate, morbidity. The combined topical-parenteral regimen has the advantage of requiring few and nontoxic injections; the primary disadvantage is that the regimen is novel and its efficacy has not been confirmed. It would be expected that cases of lesions in other areas caused by L. braziliensis complex would respond in a similar manner to these regimens. To date, however, only the efficacy of the standard antimonial regimen has been confirmed. In certain regions of Central America, other regimens may be effective. Thus, ketoconazole appears to be effective for the more rapidly self-curing forms of disease (cutaneous disease caused by L. mexicana and L. panamensis from Central America), and a short course of antimony may be effective against L. braziliensis in Guatemala.

    Full Text Available Neurofibromatosis type 1 (NF-1 is the most common form of neurofibromatosis. Since the significance of various cutaneous manifestations of NF-1 has not been known in Indian population, hence, the present study was undertaken. A total of 40 patients with NF-1 were identified between August 1998 to June 2000 with a prevalence rate of 20.4 per 10,000 individuals attending our clinic. Male to female ratio was 2.3: 1. The age of the patients ranged from 15 to 70 years with a mean age of 29.57 years. Most patients (18 cases belonged to age group of 21-30 years followed by 11-20 years age group (11 cases. Twenty four cases had onset of disease between 11-20 years of age and ten cases in 21-30 years age group. Thirty one of 40 cases presented with asymptomatic nodules, three sought medical opinion for cosmetic reasons and another three for hyper pigmented patch. Analysis of cutaneous manifestations showed, 39 of 40 cases (97.5% had neurofibromas. Palmar melanotic macules were noted in 36 (90% cases whereas café â€" au-lait macules were seen in 33(82.5% cases. Subsequent, less common findings were intertriginous freckles in 31(77.5% cases, plantar melanotic macules in 18(45% cases and generalized freckles in 4(10% cases. Statistical analysis of cases and controls revealed significant association of NF-1 with neurofibromas, palmar melanotic macules, café-au-lait macules, intertriginous freckles and plantar melanotic macules(p<0.001. This study brings into focus some of the cutaneous manifestations noted in South Indian patients especially palmar and plantar melanotic macules, not highlighted in the western literature.

  4. Modulation of cutaneous inflammation by angiotensin-converting enzyme. (United States)

    Scholzen, Thomas E; Ständer, Sonja; Riemann, Helge; Brzoska, Thomas; Luger, Thomas A


    Cutaneous neurogenic inflammation is a complex biological response of the host immune system to noxious stimuli. Present evidence suggests that zinc metalloproteases may play an important role in the regulation of neurogenic inflammation by controlling the local availability of neuropeptides, such as substance P (SP), that are capable of initiating or amplifying cutaneous inflammation after release from sensory nerves. To address the hypothesis that the dipeptidyl carboxypeptidase angiotensin-converting enzyme (ACE) is capable of modulating skin inflammation, we have analyzed murine allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD) using wild-type C57BL/6J (ACE(+/+)) or genetically engineered mice with a heterozygous deletion of somatic ACE (ACE(+/-)). In 2,4-dinitro-1-fluorobenzene-sensitized ACE(+/-) mice, ACD was significantly augmented in comparison to ACE(+/+) controls as determined by the degree of ear swelling after exposure to hapten. Likewise, systemic treatment of ACE(+/+) mice with the ACE inhibitor captopril before sensitization or elicitation of ACD significantly augmented the ACD response. In contrast, local damage and neuropeptide depletion of sensory nerves following capsaicin, injection of a bradykinin B(2), or a SP receptor antagonist before sensitization significantly inhibited the augmented effector phase of ACD in mice with functionally absent ACE. However, in contrast to ACD, the response to the irritant croton oil was not significantly altered in ACE(+/-) compared with ACE(+/+) mice. Thus, ACE by degrading bradykinin and SP significantly controls cutaneous inflammatory responses to allergens but not to irritants, which may explain the frequently observed exacerbation of inflammatory skin disease in patients under medication with ACE inhibitors.

  5. Cutaneous T-cell lymphomas and their management strategies

    Directory of Open Access Journals (Sweden)

    S S Pandey


    Full Text Available Cutaneous T-cell lymphomas (CTCLs comprise a heterogeneous group of lymphoproliferative disorders characterized by the proliferation of skin-homing post-thymic T-cells. It is the second most common extranodal non-Hodgekin′s lymphoma. Many variants of mycosis fungoides and CTCLs are known to date, differing in clinical, histological, and immunophenotypic characteristics. Oral involvement has also been reported rarely in CTCLs. Treatment depends on the disease stage or the type of variant. New insights into the disease and the number of emerging novel therapeutic options have made it an interesting area for dermatologists and medical oncologists.

  6. Primary cutaneous histoplasmosis in a skin scrape cytology

    Directory of Open Access Journals (Sweden)

    Anadi Roychowdhury


    Full Text Available Histoplasmosis refers to an infection caused by histoplasma capsulatum, a dimorphic fungus. We report a rare case of cutaneous histoplasmosis in an immunocompromised patient. The diagnosis was made by the cytopathologic examination of skin scraping smear, which showed numerous intracellular and extracellular periodic acid-schiff positive rounded yeast cells. The patient showed dramatic response with itraconazole and amphotericin B. We opine that skin scrape cytology can be useful in establishing the diagnosis of the disease, specially when the other facilities are not readily available.

    Cutaneous melanoma is a highly malignant tumour of the melanocytes presenting characteristic metabolic and biological features. Early detection decreases mortality and morbidity and provides the best chance for optimal clinical management. Imaging techniques, including scintigraphy, have assumed an important role in detection strategies. As a functional modality, nuclear medicine offers a variety of possibilities to assist in the clinical management of malignant melanoma. This review discusses the clinical aspects and treatment of melanoma, and the imaging techniques used for its diagnosis, staging and follow-up. A survey of currently available techniques is presented. (orig.)

  8. Lateral femoral cutaneous nerve block after total hip arthroplasty

    DEFF Research Database (Denmark)

    Thybo, K H; Mathiesen, O; Dahl, J B;


    BACKGROUND: Peripheral regional nerve blocks are commonly used for pain management after lower extremity surgery, but motor blockade can be a significant concern. The lateral femoral cutaneous nerve (LFCN) is a purely sensory nerve from the lumbar plexus. We hypothesised that an LFCN block would...... reduce movement-related pain after total hip arthroplasty (THA) in patients with moderate-to-severe pain. METHODS: Sixty patients with visual analogue scale (VAS) score > 40 mm during 30-degree active flexion of the hip on either the first or second postoperative day after THA were included...

  9. Cutaneous necrosis associated with the antiphospholipid syndrome and mycosis fungoides. (United States)

    Hill, V A; Whittaker, S J; Hunt, B J; Liddell, K; Spittle, M F; Smith, N P


    The development of extensive cutaneous necrosis in a patient with tumour-stage mycosis fungoides is described. Skin biopsies showed a lymphomatous infiltrate, and thrombosis of dermal blood vessels. Investigation revealed the presence of anticardiolipin antibodies, a lupus anticoagulant, and low free protein S, which contributed to a prothrombotic state. Antiphospholipid antibodies have been detected in non-Hodgkin's lymphoma, but clinical manifestations are uncommon. Such autoantibodies may be produced by neoplastic lymphoid cells. The frequency with which antiphospholipid antibodies occur in mycosis fungoides is currently unknown.

  10. CD44 variant expression in cutaneous T-cell lymphoma. (United States)

    Orteu, C H; Li, W; Allen, M H; Smith, N P; Barker, J N; Whittaker, S J


    Expression of the lymphocyte homing receptor CD44 and its splice variants have been linked to tumour dissemination and poor prognosis in non-Hodgkin's lymphoma. Specifically, the in vitro expression of variant exon V6 confers metastatic potential in rat pancreatic carcinoma cell lines. In this study, we investigated the expression of CD44 splice variants in cutaneous T-cell lymphomas, including patients with mycosis fungoides (MF), Sezary syndrome (SS), large-cell anaplastic lymphoma (LCAL) and HTLV1-associated cutaneous lymphoma. In addition, 4 involved lymph nodes from 2 patients with MF and 1 patient with SS were examined. Inflammatory dermatoses, lichen planus and psoriasis, and normal skin were also studied. Immunohistochemistry was performed using a panel of monoclonal antibodies, including those with specificity for CD44H (standard isoform) and variant exons V3, V6 and V8-9. Normal epidermal keratinocytes were consistently CD44H and CD44 V3, V6 and V8-9 positive. In all the different clinicopathological subtypes and stages of cutaneous T-cell lymphomas, including involved lymph nodes, tumour cells consistently expressed CD44H, but were CD44 V3 and V6 negative. CD44 V8-9 was expressed on a majority of tumour cells in 2/5 LCAL and on occasional tumour cells in 2/5 LCAL. Occasional V8-9 positive tumour cells were also identified in 6/13 MF, 1/4 SS and 3/4 HTLV1. In 2/3 lymph node samples from 2 patients with tumour-stage MF, CD44 V8-9 expression was found on a small percentage of atypical mononuclear cells. Scattered V8-9 positive dermal mononuclear cells were present in sections of lichen planus and psoriasis. We have found no evidence to suggest that the metastasis-associated CD44 variant exon (V6) is expressed in cutaneous T-cell lymphoma, or that CD44H expression is associated with an adverse prognostic group. It is not clear whether the strong expression of CD44 V8-9 in 2 patients with CD30 positive LCAL reflects activation status or metastatic potential.

  11. Miliarial gout: a rare presentation of extensive cutaneous tophi. (United States)

    Hung, T-L; Wang, W-M; Chiang, C-P


    Gout is a systemic disorder characterized by hyperuricemia and recurrent arthritis, most involvement of ankles, midfoot joint and first metatarsophalangeal joint, with monosodium urate crystals deposition in synovial fluid and other tissues. We present a case of 53-year-old male, who had several nontender, white-yellow papules and plaques over his elbows, knees and arms with chalk-like substances and crust on inflammatory base wax and wane in the past 2 years. Upon histopathology examination of the skin lesions, it reported as intradermal urate tophi and miliarial gout was diagnosed. This case highlights the importance of considering unusual cutaneous tophi in the differential diagnosis of deposition disorders.

  12. Cutaneous and renal geotrichosis in a giant tortoise (Geochelone elephantopus). (United States)

    Ruiz, J M; Arteaga, E; Martinez, J; Rubio, E M; Torres, J M


    A case of cutaneous and renal geotrichosis in a giant tortoise, Geochelone elephantopus, at the Zoological Park of Barcelona is reported. Fungal hyphae and spores were seen in skin and kidney. Culture of these tissues yielded Geotrichum candidum. This fungus was isolated from the faeces of 5 other giant tortoises that were housed with the dead animal and from specimens of corn hydroponic culture which is part of their diet. Arthrospore suspensions of the 2 strains isolated from the dead animal's skin and kidney were experimentally inoculated into mice and turtles (Testudo horsfiedi) in order to determine the pathogenicity of G. candidum for animal tissues. Our results confirm its low pathogenicity.

  13. Effective sunscreen ingredients and cutaneous irritation in patients with rosacea. (United States)

    Nichols, K; Desai, N; Lebwohl, M G


    Patients with rosacea are particularly susceptible to the irritation caused by sunscreen ingredients. The purpose of this bilateral comparison study was to examine the effects of different ingredients found in sunscreen on facial cutaneous irritancy in patients with rosacea. patients clinically diagnosed with rosacea were asked to test different preparations of common sunscreens on their faces. The results show that the presence or absence of appropriate protective ingredients, such as dimethicone and cyclomethicone in the vehicle, may prevent irritation from other sunscreen ingredients in patients with inflammatory conditions such as rosacea.

    Leishmania braziliensis causes cutaneous (CL) and mucosal (ML) leishmaniasis. In the mouse, Fli1 was identified as a gene influencing enhanced wound healing and resistance to CL caused by L. major. Polymorphism at FLI1 is associated with CL caused by L. braziliensis in humans, with an inverse association observed for ML disease. Here we extend the analysis to look at other wound healing genes, including CTGF, TGFB1, TGFBR1/2, SMADS 2/3/4/7 and FLII, all functionally linked along with FLI1 in ...

  15. Clinico- histopathological study of subacute cutaneous lupus erythematous

    Directory of Open Access Journals (Sweden)

    Mittal R


    Full Text Available Fourteen cases of sub acute cutaneous lupus erythematosus (SCLE were selected from Dermato- Venereology outpatients during the last 2½ years. Clinically all patients revealed photosensitivity and annular plaques either covered with peripheral collarette of scale or EM - like or DLE - like lesions. Systemic associations were arthralgia in 4, hypertension in I. rheumatoid arthritis in I and pulmonary tuberculosis in L Histopathologically epidermal atrophy, interface dermatitis, basal cell degeneration, colloid bodies and mononuclear infiltrate of dermis were salient features. Good response to 15 mg prednisolonc, medium potency topical steroids and sunscreens was seen in all cases.

  16. Disseminated cryptococcosis with cutaneous involvement in an immunocompetent patient* (United States)

    Sacht, Gabriely Lessa; de Lima, Alexandre Moretti; Perdomo, Yuri Chiarelli; Boigues, Rafaela Suguimoto; Takita, Luiz Carlos; Hans Filho, Günter


    Cryptococcosis is a fungal infection of opportunistic behavior that is unusual in immunocompetent patients. We report a rare case of disseminated cryptococcosis with cutaneous involvement in an immunocompetent individual. During hospitalization, Cryptococcus gattii was isolated from skin lesions, lung and spinal fluid. The diagnosis of disseminated cryptococcosis was confirmed and treatment was established. The patient showed improvement. Due to the probable clinical severity of the disease and the possibility that skin lesions may be the first manifestation of this illness, prompt diagnosis must be established and treatment provided.

  17. Early detection of cutaneous melanoma by sequential digital dermatoscopy (SDD). (United States)

    Kraus, Sophie Luise; Haenssle, Holger Andreas


    The early diagnosis and excision of cutaneous melanoma is essential for an improved prognosis of the disease. Besides the investigation of pigmented lesions with the unaided eye and conventional dermatoscopy, long-term sequential digital dermatoscopy has been shown to improve the sensitivity of melanoma detection, especially in high-risk patients. In addition to the static clinical and dermatoscopic assessment, the sequential digital dermatoscopy strategy helps to detect changes over time. This review summarizes the latest developments in the field of sequential digital dermatoscopy, describes current strategies for the selection of patients and lesions to monitor, and suggests objective criteria that should lead to an excisional biopsy.

  18. A case report of cutaneous larva migrans in Argentina

    Javier Bava; Lucia G Gonzalez; Celeste M Seley; Gisela P Lpez; Alcides Troncoso


    Cutaneous larva migrans (CLM) represents the most common tropically acquired dermatosis. CLM is caused by infection with hookworm larvae in tropical and sub-tropical areas, and people who have a history of foreign travel and of walking barefoot on sandy soil or beaches are at a high risk of getting infected with it. The diagnosis is usually made on the basis of the typical appearance of the lesion, intense itching and history of foreign travel. CLM is a common parasitic skin disease that can be easily prevented by wearing 'protective' footwear. A case of CLM is described in this article.

    Ajay Kumar


    Full Text Available The basal cell carcinoma is the most common skin tumour especially affecting the white individuals worldwide. The exact incidence of basal cell carcinoma is not known from India but non melanoma skin cancers comprises about 1-2% of cutaneous tumour in India. The most common skin tumour is squamous cell carcinoma in albinism and the incidence of basal cell carcinoma is less. Hereby, we report a peculiar case of basal cell carcinoma in albinism to highlights the importance of early recognition and diagnosis of suspected lesions by performing histopathological examination in unusual circumstances.

  1. Cutaneous metastasis of prostate carcinoma to neck and upper chest

    Directory of Open Access Journals (Sweden)

    Nitin Abrol


    Full Text Available Prostate adenocarcinoma is the most common urologic malignant neoplasm in men. Metastasis to skin is rarely reported and usually occurs late. The incidence and appearance of cutaneous metastasis are not well established in patients with prostate adenocarcinoma and their recognition remains poor among practicing urologists. Their clinical appearance may mimic other common dermatologic disorders. Definitive diagnosis requires a high index of suspicion. Immunohistochemical staining helps in establishing the diagnosis. We report a case of prostate adenocarcinoma presenting with widespread metastasis, including those to dermis and subcutaneous tissue of neck and upper chest.

  2. Recurrent cutaneous abscesses in two Italian family members

    Directory of Open Access Journals (Sweden)

    Carmen Cantisani


    Full Text Available Environmental mycobacteria are the causative factors of an increasing number of infections worldwide. Cutaneous infections as a result of such mycobacteria are often misdiagnosed, and their treatment is difficult since they can show in vivo and in vitro multidrug resistance. Absence of pathognomonic clinical signs and variable histological findings often delay diagnosis. We report a case of localized recurrent soft tissue swelling by Mycobacterium marinum in 2 members of the same family. The cases are being reported for their uncommon clinical presentation and the associated etiological agent. Patients recovered completely following therapy with rifampicin 600 mg plus isoniazide 300 mg daily for 45 days.

    Leprosy is a disease typically found in the tropics. Patients with leprosy can have varying presentation with constitutional symptoms, joint pains, skin nodules, and rarely a vasculitis-like picture with skin ulcers and neuropathy. We present a young lady who presented with the rare manifestation of skin infarcts mimicking cutaneous vasculitis, diagnosed on histopathology to have Lucio phenomenon on a background of lepromatous leprosy. With increasing migration and widespread use of biologic response modifiers, clinicians all over the world need to be aware of various presentations of leprosy as well as needing to keep an open mind while considering the differential diagnoses of vasculitis.

    Estrozi, Bruna; Sanches, José A; Varela, Paulo C S; Bacchi, Carlos E


    Mantle cell lymphoma (MCL) commonly involves extranodal sites, usually as a manifestation of disseminated disease. In rare cases, MCLs may arise as a primary tumor in the skin. Blastoid mantle cell lymphoma (BV-MCL) is a rare variant and has a more aggressive clinical course. The phenotype of BV-MCL is characterized as CD20+, CD5+, cyclin D1+, CD23-, and CD10-. Interphase fluorescence in situ hybridization shows a characteristic t(11;14) fusion pattern. We report a case of a BV-MCL arising in skin as primary cutaneous MCL with the characteristic immunophenotype and translocation.

    Cutaneous Leishmaniasis (CL) remains a major world health problem, with about 1.5 million new cases each year. Caused by protozoa Leishmania, in South America, this infection can vary from a chronic skin ulcer, to an erosive mucosal disease and severe facial disfigurement. Pentavalent antimony (Sb{sup +5}) as sodium stibogluconate (Pentostam) or meglumine antimoniate (Glucantime) are main drugs for treating most forms of human leishmaniasis. For six decades, despite the recent developments, the effective therapy to cutaneous leishmaniasis has been based on long parenteral courses of such drugs, even though these are fairly costly, toxic and inconvenient to use, without adequate knowledge on their pharmacokinetics or mechanism of action. Pharmacokinetics studies could be based on bioactive traceable drugs, usually with radioactive isotopes, but antimony radioisotopes are unavailable commercially. Neutron irradiation is a powerful tool in the analysis of mineral content of samples, for antimony, there are at least two main isotopes that could be formed after neutron irradiation in nuclear reactor. The aim of the present study was to construct antimony salts with those radioisotopes to obtain tracers to compare the pharmacokinetic and the tissue distribution of neutron irradiated meglumine antimoniate in healthy and cutaneous leishmaniasis experimentally infected mice. Meglumine antimoniate, (Glucantime, Aventis, S.P, Brazil), was neutron irradiated inside the IEA-R1 nuclear reactor (IPEN/CNEN-SP), producing two radioisotopes {sup 122}Sb and {sup 124}Sb. Its biodistribution was verified in BALB/c mice experimentally infected with Leishmania (Leishmania) Amazonensis, which received a single intraperitoneal dose of the drug. At different times after injection, the tissues and blood were excised and activity measured in a NaI (Tl) scintillation counter. Compared with the healthy mice, experimentally infected mice had significantly lower maximum concentration of antimony

  6. Scalp fibroma: a rare cutaneous manifestation of tuberous sclerosis. (United States)

    Sharma, Bhawna; Prakash, Swayam; Sannegowda, Raghavendra Bakki; Panagariya, Ashok


    We report a case of a 23-year-old woman with a history of generalised tonic-clonic seizures, reddish brown maculopapular swelling over the face and an enlarging swelling over the scalp. Physical examinations revealed angiofibroma of the face and other typical cutaneous lesions of tuberous sclerosis, for example, shagreen patch and periungual fibroma. Scalp swelling was labelled as fibroma by dermatologists, which was further supported by the histopathological findings. Fibroma of the face is one of the commonest lesions, however, fibroma of the scalp is a rarely described entity.

  7. Cutaneous Squamous Cell Carcinoma with Invasion through Ear Cartilage

    Directory of Open Access Journals (Sweden)

    Julie Boisen


    Full Text Available Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell carcinoma that exhibited full-thickness perforation of the scapha cartilage. Permanent sections through the eroded cartilage confirmed tumor invasion extending to the posterior ear skin.

  8. Lack of significant skin inflammation during elimination by apoptosis of large numbers of mouse cutaneous mast cells after cessation of treatment with stem cell factor. (United States)

    Maurer, Marcus; Galli, Stephen J


    We previously reported that subcutaneous (s.c.) administration of stem cell factor (SCF), the ligand for the c-Kit receptor, to the back skin of mice promotes marked local increases in the numbers of cutaneous mast cells (MCs), and that cessation of SCF treatment results in the rapid reduction of cutaneous MC populations by apoptosis. In the present study, we used the 125I-fibrin deposition assay, a very sensitive method for quantifying increased vascular permeability, to assess whether the clearance of large numbers of apoptotic MCs is associated with significant cutaneous inflammation. The s.c. injection of rrSCF164 (30 or 100 microg/kg/day) or rrSCF164-peg (polyethylene glycol-treated SCF, 30 or 100 microg/kg/day) for 23 days increased the numbers of dermal MCs at skin injection sites from 5.1+/-0.7 MCs/mm2 to 36.4+/-4.1, 34.7+/-9.7, 52.5+/-5.8, and 545+/-97 MCs/mm2, respectively. In contrast, MC numbers were markedly lower in mice that had been treated with SCF for 21 days, followed by 2 days of injection with the vehicle alone. Notably, when tested during the period of rapid reduction of skin MCs,125I-fibrin deposition in the skin was very similar to that in mice receiving continuous treatment with SCF or vehicle. We conclude that the rapid elimination of even very large populations of MCs by apoptosis, which also results in the clearance of the considerable quantities of proinflammatory products stored by these cells, does not lead to significant local cutaneous inflammatory responses.

    Fatani, Mohammad Ibrahim; Hussain, Waleed Mohd; Baltow, Badee; Alsharif, Sahar


    A cutaneous horn is a rare clinical condition characterised by a conical projection of hyperkeratotic epidermis. Cutaneous horns most commonly arise from sun-exposed skin in elderly men, but may arise from any part of the body at any age in men and women. When a cutaneous horn forms, it is important to determine the underlying cause. Various skin diseases may present with cutaneous horns including viral warts, actinic keratosis, keratoacanthoma, seborrhoeic keratosis, pyogenic granuloma, discoid lupus erythematosus, verruca vulgaris, Bowen's disease, basal cell carcinoma and squamous cell carcinoma. The underlying pathology is benign in 61.1% of cases, premalignant in 23.2% of cases and malignant in 15.7% of cases. We report a patient with a cutaneous horn arising from an area of discoid lupus erythematosus on the scalp.

    Full Text Available Case Report. A 47-year-old man presented with blurred vision in the right eye. Ophthalmoscopic examination showed several placoid, pigmented lesions in the posterior pole and midperiphery of the retina of both eyes. Results. Patient referred a cutaneous malignant melanoma on the back skin removed 6 years ago. A systemic workup revealed multiple metastases in liver and spleen. After an exhaustive study we concluded that it was a dissemination of a cutaneous malignant melanoma with bilateral choroidal metastases, liver and spleen metastases. The patient obtained clinical ocular improvement after palliative chemotherapy, although he died in the following months. Pathological examination of the lesions confirmed the diagnosis of choroidal metastases from a malignant cutaneous melanoma. Conclusions. Monitoring patients who have had cutaneous malignant melanoma is very important, since melanoma metastases may occur even many years after the diagnosis of the primary tumor. Choroidal metastases from cutaneous melanoma are uncommon but we should be aware because their appearance worsens prognosis.

  2. Rhomboid cutaneous flap for defect correction after resection of trichoblastoma on dogs' face

    Directory of Open Access Journals (Sweden)

    Priscilla Bartolomeu de Araújo


    Full Text Available ABSTRACT: Surgical excision of neoplasms usually requires a large incision with safety margin, resulting in large cutaneous defects. Skin flaps permit closure of extensive cutaneous defects that would not be closed directly. The rhomboid cutaneous flap can be used in places of the body where a rhomboid defect with internal angles of 60 and 120 degrees can be made. The aim of this paper is to report the her use for reconstruction of the defect created after resection of a tumor on dogs' face . Total removal of the tumor and a safety margin was performed, and then the surgical defect was reconstructed with a rhomboid cutaneous flap. The final result was satisfactory, with an esthetically and functional acceptable scar, a without deformities to the oral commissure or eye. The cutaneous flap was considered a viable alternative for reconstruction of large surgical defects, of relatively simple execution and good functional and cosmetic results.

  5. Special Administrative Jurisdictions

    Directory of Open Access Journals (Sweden)

    Vasilica Negruț


    Full Text Available The Constitution of Romania revised in 2003 establishes the free and voluntary nature of the special administrative jurisdictions, a fact which allows the party concerned to address either the administrative-judicial body or directly the court. If they opted for the administrative-judicial way, it must be followed to the end, then, under the terms established by the law, the party may address the court, under the right of access to justice provided by article 21 of the constitution. The administrative jurisdiction is an activity of solving an administrative litigation by specific procedural rules of judicial procedure, based on the principle of the independence, of insuring the right to defense and the administrative-jurisdictional independence activity, which results in a jurisdictional administrative act. In order to achieve the objectives of the paper, namely to highlight the essential elements of the resolution of litigation according to special administrative jurisdictions, we have achieved an analysis of the legislative acts referring to this activity, of the doctrine and jurisprudence. After examination and empirical research, the paper summarizes and specifies the general conclusions on the role and importance of special administrative courts.

  7. Decomposition and transformation of cutin and cutan biopolymers in soils: effect on their sorptive capabilities (United States)

    Shechter, M.; Chefetz, B.


    Plant cuticle materials, especially the highly aliphatic biopolymers cutin and cutan, have been reported as highly efficient natural sorbents. The objective of this study was to examine the effects of decomposition on their sorption behavior with naphthol and phenanthrene. The level of cutin and cutan was reduced by 15 and 27% respectively during the first 3 mo of incubation. From that point, the level of the cutan did not change, while the level of the cutin continued to decrease up to 32% after 20 mo. 13C NMR analysis suggested transformation of cutan mainly within its alkyl-C structure which are assigned as crystalline moieties. Cutin, however, did not exhibit significant structure changes with time. The level of humic-like substances increased due to cutin decomposition but was not influenced in the cutan system after 20 mo of incubation. This indicates that the cutin biopolymer has been decomposed and transformed into humic-like substances, whereas the cutan was less subject to transformation. Decomposition affected sorption properties in similar trends for both cutin and cutan. The Freundlich capacity coefficients (KFOC) of naphthol were much lower than phenanthrene and were less influenced by the decomposition, whereas with phenanthrene KFOC values increased significantly with time. Naphthol exhibited non-linear isotherms; and nonlinearity was decreased with incubation time. In contrast, phenanthrene isotherms were more linear and showed only moderate change with time. The decrease in the linearity of naphthol isotherms might relate to the transformation of the sorption sites due to structural changes in the biopolymers. However, with phenanthrene, these changes did not affect sorption linearity but increased sorption affinities mainly for cutan. This is probably due to decomposition of the rigid alkyl-C moieties in the cutan biopolymer. Our data suggest that both biopolymers were relatively stable in the soil for 20 mo. Cutan is less degradable than cutin

  8. Cutaneous Adverse Events Associated with Interferon-β Treatment of Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    Annette Kolb-Mäurer


    Full Text Available Interferons are widely used platform therapies as disease-modifying treatment of patients with multiple sclerosis. Although interferons are usually safe and well tolerated, they frequently cause dermatological side effects. Here, we present a multiple sclerosis (MS patient treated with interferon-β who developed new-onset psoriasis. Both her MS as well as her psoriasis finally responded to treatment with fumarates. This case illustrates that interferons not only cause local but also systemic adverse events of the skin. These systemic side effects might indicate that the Th17/IL-17 axis plays a prominent role in the immunopathogenesis of this individual case and that the autoimmune process might be deteriorated by further administration of interferons. In conclusion, we think that neurologists should be aware of systemic cutaneous side effects and have a closer look on interferon-associated skin lesions. Detection of psoriasiform lesions might indicate that interferons are probably not beneficial in the individual situation. We suggest that skin lesions may serve as biomarkers to allocate MS patients to adequate disease-modifying drugs.

    Lianet Monzote


    Full Text Available Phenolic compounds (PCs are well-known phytochemicals found in plants that have been studied for their pharmacological properties. In particular, the potentialities of PCs as anti-leishmanial agents have been reported. In the present study, we evaluated 10 PCs for in-vitro anti-leishmanial activity and two PCs, p-coumaric acid (CA and gentisic acid (GA against experimental cutaneous leishmaniasis in BALB/c mice infected with L. amazonensis. Five doses of each pure compound were administrated every 4 days at 30 mg/kg by intralesional route and disease progression was compared with animals treated with glucantime (GTM. All tested compounds inhibited intracellular amastigotes growing, with IC50 values between 4.4 and 25.5 µM. Treated animals with GA showed a significant reduction (p 0.05 parasite burden as control and GTM treated animals. The present findings established that CA and GA have significant anti-leishmanial effects. Further experiments on formulation design, mechanism of action and probably anti-inflammatory / immune-modulator activity of GA could be encouraged.

  10. Cutaneous reactions to heparin therapy: when are they caused by heparin allergy?

    Directory of Open Access Journals (Sweden)

    Giuliana Zisa


    Full Text Available Introduction: Little is known about the incidence and causes of heparin-induced skin lesions. The most commonly reported causes are delayed-type hypersensitivity reactions. We describe 3 patients who were referred to our staff between March and October 2009 for suspected heparin allergies. All were scheduled to undergo major surgery (cardiovascular or orthopedic. Materials and methods: All 3 patients reported the development of itchy, erythematous rashes a few days after the subcutaneous administration of heparin (nadroparin calcium in cases 1 and 2, unspecified in case 3. Each of them underwent a diagnostic work-up for heparin allergy, which included prick and intradermal tests with commonly used heparins and patch testing with undiluted heparins and disinfectants. Results: Patch tests with disinfectants were negative in all 3 cases. In case 2, all allergological tests were negative. In cases 1 and 3, delayed positivity emerged for nadroparin calcium and at least one other heparin tested. Intravenous and/or subcutaneous provocation testing was done with an alternative heparin which produced negative results in skin tests (heparin sodium in case 1, pentasaccharide fondaparinux in case 3. In both cases the alternative drug was tolerated. After our evaluation, all 3 patients underwent surgery with no heparin-related complications. Discussion: The presenting clinical features in these 3 cases provided no information on which reactions were likely to be allergic: all 3 patients presented with similar local delayed reaction. The allergic reactions were identified only after cutaneous testing.

  11. Role for Lyt-2+ T cells in resistance to cutaneous leishmaniasis in immunized mice

    Energy Technology Data Exchange (ETDEWEB)

    Farrell, J.P.; Muller, I.; Louis, J.A.


    The role of Lyt-2+ T cells in immunologic resistance to cutaneous leishmaniasis was analyzed by comparing infection patterns in resistant C57BL/6 mice and susceptible BALB/c mice induced to heal their infections after sub-lethal irradiation or i.v. immunization, with similar mice treated in vivo with anti-Lyt-2 antibodies. Administration of anti-Lyt-2 mAb resulted in a dramatic reduction in the number of lymphoid cells expressing the Lyt-2+ phenotype. Such treatment led to enhanced disease in both resistant C57BL/6 and irradiated BALB/c mice, as assessed by lesion size, but did not affect the capacity of these mice to ultimately resolve their infections. In contrast, anti-Lyt-2 treatment totally blocked the induction of resistance in i.v. immunized mice. These results suggest, that Lyt-2+ T cells may play a role in immunity to a Leishmania major infection and that their relative importance to resistance may depend on how resistance is induced.

  12. Topically Applied Hsp90 Blocker 17AAG Inhibits Autoantibody-Mediated Blister-Inducing Cutaneous Inflammation. (United States)

    Tukaj, Stefan; Bieber, Katja; Kleszczyński, Konrad; Witte, Mareike; Cames, Rebecca; Kalies, Kathrin; Zillikens, Detlef; Ludwig, Ralf J; Fischer, Tobias W; Kasperkiewicz, Michael


    Cell stress-inducible Hsp90 has been recognized as key player in mediating inflammatory responses. Although its systemic blockade was successfully used to treat autoimmune diseases in preclinical models, efficacy of a topical route of Hsp90 inhibitor administration has so far not been evaluated in chronic inflammatory and autoimmune-mediated dermatoses. Here, effects of the Hsp90 blocker 17-allylamino-demethoxygeldanamycin (17AAG) applied topically to the skin were determined in experimental inflammatory epidermolysis bullosa acquisita (EBA), an anti-type VII collagen autoantibody-induced blistering skin disease. Topical 17AAG ameliorated clinical disease severity when given before or during the occurrence of skin lesions without causing cutaneous or systemic toxicity in mice with antibody transfer- and immunization-induced EBA. In both EBA models and in the setting of locally induced inflammation, topical 17AAG treatment was associated with (i) reduced neutrophilic infiltrates, (ii) decreased NF-κB activation, (iii) lowered expression of matrix metalloproteinases and Flii, and (iv) induction of anti-inflammatory Hsp70 in the skin. Our results suggest that topical delivery of Hsp90 antagonists, offering the benefit of a reduced risk of systemic adverse effects of Hsp90 inhibition, may be useful for the control of EBA and possibly other related inflammatory skin disorders.

  13. Evaluation of Topical Tocopherol Cream on Cutaneous Wound Healing in Streptozotocin-Induced Diabetic Rats

    Teoh Seong Lin


    Full Text Available Diabetes is a common cause of delayed wound healing. The aim of the study was to determine the effect of topical administration of tocopherol cream on the wound healing process in diabetic rats. The study was conducted using 18 male Sprague Dawley rats which were divided into three groups: (I diabetic rats receiving control cream , (II diabetic rats receiving 0.06% tocopherol cream , and (III diabetic rats receiving 0.29% tocopherol cream . Four cutaneous wounds were created at the dorsal region of the rats. Wound healing was assessed by total protein content, rate of wound closure estimation, and histological studies on the tenth day after wounding. Tocopherol treatment enhanced the wound healing process by increasing rate of wound closure and total protein content significantly compared to the control group. Histological observation also showed better organized epithelium and more collagen fibers in the tocopherol treated groups. Application of tocopherol cream enhances wound healing process in diabetic condition which is known to cause delay in wound healing.

    Diabetes is a common cause of delayed wound healing. The aim of the study was to determine the effect of topical administration of tocopherol cream on the wound healing process in diabetic rats. The study was conducted using 18 male Sprague Dawley rats which were divided into three groups: (I) diabetic rats receiving control cream (n = 6), (II) diabetic rats receiving 0.06% tocopherol cream (n = 6), and (III) diabetic rats receiving 0.29% tocopherol cream (n = 6). Four cutaneous wounds were created at the dorsal region of the rats. Wound healing was assessed by total protein content, rate of wound closure estimation, and histological studies on the tenth day after wounding. Tocopherol treatment enhanced the wound healing process by increasing rate of wound closure and total protein content significantly (P < 0.05) compared to the control group. Histological observation also showed better organized epithelium and more collagen fibers in the tocopherol treated groups. Application of tocopherol cream enhances wound healing process in diabetic condition which is known to cause delay in wound healing. PMID:23097676

  15. Novel locally active estrogens accelerate cutaneous wound healing. A preliminary study. (United States)

    New 17beta-estradiol (E2) derivatives 1-11 were synthesized from an estrone derivative by addition of organometallic reagents prepared from protected alpha,omega-alkynols and further elaboration of the addition products. The estrogenic activity of these novel compounds was determined using in vitro binding competition assay and transactivation analysis. Among the E2 derivatives synthesized, compound 2 showed the highest transactivation potency and was therefore tested for its ability to modulate cutaneous wound healing in vivo. Compound 2's ability to accelerate wound healing in ovariectomized mice and decrease the production of inflammatory molecules was comparable to that of E2. However, the activity of compound 2 was not superimposable to E2 with regard to the cells involved in the wound repairing process. When locally administered, compound 2 did not show any systemic activity on ER. This class of compounds with clear beneficial effects on wound healing and suitable for topical administration may lead to the generation of innovative drugs for an area of unmet clinical need.

  16. Imaging Cutaneous T-Cell Lymphoma with Optical Coherence Tomography

    Directory of Open Access Journals (Sweden)

    Hans Christian Ring


    Full Text Available Aim: To investigate the presentation of a patch-stage cutaneous T-cell lymphoma (CTCL using optical coherence tomography (OCT. Methods: A patient with a patch caused by CTCL was photographed digitally, OCT-scanned and biopsied. A normal skin area adjacent to the patch was OCT-scanned for comparison, but not biopsied. The OCT image and the histological image were compared. Results: The OCT images illustrated a thickened and hyperreflective stratum corneum. OCT also demonstrated several elongated hyporeflective structures in the dermis. The largest structure was measured to have a width of 0.13 mm. A good immediate correlation was found between histology and OCT imaging of the sample. Conclusion: The aetiology of the elongated structures is thought to be lymphomatous infiltrates. Similar findings have been described in ocular lymphoma and may therefore be an important characteristic of cutaneous lymphoma. It may further be speculated that the differences in OCT images may reflect the biological behaviour of the infiltrate. This observation therefore suggests that OCT imaging may be a relevant tool for the in vivo investigation of mycosis fungoides and other CTCLs, but in order to verify these observed patterns in OCT imaging, further investigations will be required.

  17. Secondary Cutaneous Amyloidosis in a Patient with Mycosis Fungoides (United States)

    Nam, Chan Hee; Park, Min Kee; Choi, Mi Soo; Hong, Seung Phil; Park, Byung Cheol


    Secondary cutaneous amyloidosis refers to clinically unapparent amyloid deposits within the skin in association with a pre-existing skin condition or skin tumors, such as basal cell carcinoma, porokeratosis, solar elastosis, Bowen's disease, and mycosis fungoides. A 70-year-old woman presented with a 6-month history of asymptomatic multiple yellowish plaques on both legs. She had been diagnosed with mycosis fungoides 7 years ago and was treated with psoralen and ultraviolet A radiation (PUVA) therapy, narrow-band ultraviolet B (UVB) therapy, and acitretin for 5 years. Finally, she reached complete remission of mycosis fungoides. However, new yellowish lesions started to appear 1 year after discontinuing the phototherapy. A physical examination revealed multiple yellowish plaques on both extremities. The plaques were well circumscribed and slightly elevated. All laboratory tests were normal. A biopsy specimen showed multiple nodular deposits of eosinophilic amorphous material in papillary dermis and upper reticular dermis. The deposits represented apple green birefringence on Congo red stain viewed under polarized light. Acellular small nodules in the upper dermis consisted of randomly oriented, non-branching, 6.67~12.7 nm thick amyloid fibrils on electron microscopy. We report an interesting and rare case of secondary cutaneous amyloidosis after narrow-band UVB therapy and PUVA therapy in a patient with mycosis fungoides. PMID:28223751

  18. Advances in the treatment of cutaneous lupus erythematosus. (United States)

    Kuhn, A; Landmann, A; Wenzel, J


    Lupus erythematosus (LE) is a multifactorial autoimmune disease with clinical manifestations of differing severity which may present with skin manifestations as primary sign of the disease (cutaneous lupus erythematosus, CLE) or as part of a disease spectrum (systemic lupus erythematosus, SLE). To date, no drugs are approved specifically for the treatment of CLE and only single agents have been applied in randomized controlled trials. Therefore, topical and systemic agents are used "off-label", primarily based on open-label studies, case series, retrospective analyses, and expert opinions. In contrast, several agents, such as hydroxychloroquine, chloroquine, cyclophosphamide, azathioprine, and belimumab, are approved for the treatment of SLE. Recent approaches in the understanding of the molecular pathogenesis of LE enabled the development of further new agents, which target molecules such as interleukin 6 (IL-6) and interferon (IFN). Only single trials, however, applied these new agents in patients with cutaneous involvement of the disease and/or included endpoints which evaluated the efficacy of these agents on skin manifestations. This article provides an updated review on new and recent approaches in the treatment of CLE.

  19. Wnt signaling induces epithelial differentiation during cutaneous wound healing

    Directory of Open Access Journals (Sweden)

    Hocking Anne


    Full Text Available Abstract Background Cutaneous wound repair in adult mammals does not regenerate the original epithelial architecture and results in altered skin function. We propose that lack of regeneration may be due to the absence of appropriate molecular signals to promote regeneration. In this study, we investigated the regulation of Wnt signaling during cutaneous wound healing and the consequence of activating either the beta-catenin-dependent or beta-catenin-independent Wnt signaling on epidermal architecture during wound repair. Results We determined that the expression of Wnt ligands that typically signal via the beta-catenin-independent pathway is up-regulated in the wound while the beta-catenin-dependent Wnt signaling is activated in the hair follicles adjacent to the wound edge. Ectopic activation of beta-catenin-dependent Wnt signaling with lithium chloride in the wound resulted in epithelial cysts and occasional rudimentary hair follicle structures within the epidermis. In contrast, forced expression of Wnt-5a in the deeper wound induced changes in the interfollicular epithelium mimicking regeneration, including formation of epithelia-lined cysts in the wound dermis, rudimentary hair follicles and sebaceous glands, without formation of tumors. Conclusion These findings suggest that adult interfollicular epithelium is capable of responding to Wnt morphogenic signals necessary for restoring epithelial tissue patterning in the skin during wound repair.

  20. Mast cells and basophils in cutaneous immune responses. (United States)

    Otsuka, A; Kabashima, K


    Mast cells and basophils share some functions in common and are generally associated with T helper 2 (Th2) immune responses, but taking basophils as surrogate cells for mast cell research or vice versa for several decades is problematic. Thus far, their in vitro functions have been well studied, but their in vivo functions remained poorly understood. New research tools for their functional analysis in vivo have revealed previously unrecognized roles for mast cells and basophils in several skin disorders. Newly developed mast cell-deficient mice provided evidence that mast cells initiate contact hypersensitivity via activating dendritic cells. In addition, studies using basophil-deficient mice have revealed that basophils were responsible for cutaneous Th2 skewing to haptens and peptide antigens but not to protein antigens. Moreover, human basophils infiltrate different skin lesions and have been implicated in the pathogenesis of skin diseases ranging from atopic dermatitis to autoimmune diseases. In this review, we will discuss the recent advances related to mast cells and basophils in human and murine cutaneous immune responses.

  1. Complement deficiency promotes cutaneous wound healing in mice. (United States)

    Rafail, Stavros; Kourtzelis, Ioannis; Foukas, Periklis G; Markiewski, Maciej M; DeAngelis, Robert A; Guariento, Mara; Ricklin, Daniel; Grice, Elizabeth A; Lambris, John D


    Wound healing is a complex homeostatic response to injury that engages numerous cellular activities, processes, and cell-to-cell interactions. The complement system, an intricate network of proteins with important roles in immune surveillance and homeostasis, has been implicated in many physiological processes; however, its role in wound healing remains largely unexplored. In this study, we employ a murine model of excisional cutaneous wound healing and show that C3(-/-) mice exhibit accelerated early stages of wound healing. Reconstitution of C3(-/-) mice with serum from C3(+/+) mice or purified human C3 abrogated the accelerated wound-healing phenotype. Wound histology of C3(-/-) mice revealed a reduction in inflammatory infiltrate compared with C3(+/+) mice. C3 deficiency also resulted in increased accumulation of mast cells and advanced angiogenesis. We further show that mice deficient in the downstream complement effector C5 exhibit a similar wound-healing phenotype, which is recapitulated in C5aR1(-/-) mice, but not C3aR(-/-) or C5aR2(-/-) mice. Taken together, these data suggest that C5a signaling through C5aR may in part play a pivotal role in recruitment and activation of inflammatory cells to the wound environment, which in turn could delay the early stages of cutaneous wound healing. These findings also suggest a previously underappreciated role for complement in wound healing, and may have therapeutic implications for conditions of delayed wound healing.

  2. Finite Element Modeling of Cutaneous Electrical Stimulation for Sensory Feedback

    LI Si; CHAI Guo-hong; SUI Xiao-hong; LAN Ning


    It is currently difficult for the amputee to perceive environmental information such as tactile pressure on the fingertip of the present upper limb prostheses. Sensory feedback induced by cutaneous electrical stimulation can be used to transmit tactile information from hand prostheses to sensory nerve of intact upper arm, thus producing the corresponding perceptions in human brain. In order to have a deeper understanding on the distribution of stimulation current within the limb, and find a better placement of the stimulating and reference electrodes, we constructed a three-dimensional upper-limb model to systematically study the effect of electrode placement on current distribution based on finite element analysis. In these simulations, the reference electrode is positioned at four different locations around and on the axial direction of the arm. The results show that with the increase of distance between reference electrode and stimulating electrode, the current density increases in the skin layer of the upper limb. When the reference electrode is on the opposite side of stimulating electrode around the arm, the current is more concentrated in the skin layer, which is in line with recent findings in psychophysiological experiments. But better spatial selectivity could be achieved when the reference electrode is closer to the stimulating electrode around the arm, and it is more obvious in comparison with that on the axial direction. These findings will provide insights for the design of electrode array used for evoking cutaneous sensory afferents.

  3. Cutaneous silent period in human FDI motor units. (United States)

    Kahya, Mehmet C; Yavuz, S Utku; Türker, Kemal S


    In this study, we aimed to use both the probability-based and the frequency-based analyses methods simultaneously to examine cutaneous silent period (CSP) induced by strong electrical currents. Subjects were asked to contract their first dorsal interosseus muscles so that one motor unit monitored via intramuscular wire electrodes discharged at a rate of approximately 8 Hz. Strong electrical stimuli were delivered to the back of the hand that created a subjective discomfort level of between 4 and 7 [0-10 visual analogue scale] and induced cutaneous silent period in all units. It was found that the duration of the CSP was significantly longer when the same data were analysed using frequency-based analysis method compared with the probability-based methods. Frequency-based analysis indicated that the strong electrical stimuli induce longer lasting inhibitory currents than what was indicated using the probability-based analyses such as surface electromyogram and peristimulus time histogram. Usage of frequency-based analysis for bringing out the synaptic activity underlying CSP seems essential as its characteristics have been subject to a large number of studies in experimental and clinical settings.

  4. American cutaneous leishmaniasis: presentation and problems of patient management

    Jeffrey D. Chulay


    Full Text Available We report our experience with the diagnosis and treatment of 60 patients with American cutaneous leishmaniasis. They were infected in Panama (55, Brazil (4 or Colombia (I. Among 35 patients with a 3 week exposure in Panama, the mean maximum incubation period was 33 days (range 4-81 days. Diagnosis was delayed an average of 93 days after onset of skin lesions, due to the patient's delay in seeking medical attention (31 days, medical personnel's delay in considering the diagnosis (45 days, and the laboratory's delay in confirming the diagnosis (17 days. Forty-four patients (73% developed ulcers typical of cutaneous leishmaniasis. Sixteen additional patients (27% had atypical macular, papular, squamous, verrucous or acneiform skin lesions that were diagnosed only because leishmanial cultures were obtained. Of the 59 patients treated with pentavalent antimonial drugs, only 34 (58% were cured after the first course of treatment. Lesions which were at least 2 cm in diameter, ulcerated, or caused by Leishmania braziliensis were less likely to be cured after a single course of treatment than were lesions smaller than 2 cm, nonulcerated or caused by Leishmania mexicana or Leishmania donovani.

  5. Effect of Propolis on Experimental Cutaneous Wound Healing in Dogs (United States)


    This study evaluates clinically the effect of propolis paste on healing of cutaneous wound in dogs. Under general anesthesia and complete aseptic conditions, two full thickness skin wounds (3 cm diameter) were created in each side of the chest in five dogs, one dorsal and one ventral, with 10 cm between them. These wounds were randomly allocated into two groups, control group (10 wounds) and propolis group (10 wounds). Both groups were represented in each dog. The wounds were cleaned with normal saline solution and dressed with macrogol ointment in control group and propolis paste in propolis group, twice daily till complete wound healing. Measurement of the wound area (cm2) was monitored planimetrically at 0, 7, 14, 21, 28, and 35 days after injury. The data were analyzed statistically. The results revealed a significant reduction in the wound surface area in the propolis group after 14 and 21 days compared to control group. The wound reepithelization, contraction, and total wound healing were faster in propolis group than in control group during five weeks of study. In conclusion, propolis paste has a positive impact on cutaneous wound healing and it may be suggested for treating various types of wounds in animals. PMID:26783495

  6. Skin appendageal immune reactivity in a case of cutaneous lupus

    Directory of Open Access Journals (Sweden)

    Ana Maria Abreu Velez


    Full Text Available Background: Discoid lupus erythematosus is a cutaneous disease with a worldwide distribution, and its pathogenesis remains unclear. Case Report: A 41 year old male was evaluated for hair loss, in patches on the scalp. We studied selected adaptor proteins expressed in T, natural killer, neutrophil and mast cells; these proteins are important mediators for antigen receptor signaling in situ. Methods: Skin biopsies for hematoxylin and eosin examination, as well as for direct immunofluorescence and immunohistochemistry analysis were performed. Results: Hematoxylin and eosin staining demonstrated classic features of lupus with focal dermal scarring; epidermal atrophy was noted, with lymphohistiocytic infiltrates around the skin appendages. Direct immunofluoresence revealed classic, lupus band positive staining along the dermal/epidermal junction. In addition, immune reactants were identified in neurovascular areas, and around pilosebaceous units. Immunohistochemistry staining showed positive staining for the T-cell antigen receptor zeta chain, the linker for activation of T cells, myeloperoxidase, cyclo-oxygenase 2, melanoma-associated antigen 1, B cell leukemia/lymphoma-2 associated X protein, and BCL-2 markers. The positive staining was observed within the dermal inflammatory infiltrate, around pilosebaceous units, upper dermal blood vessels, and focally within eccrine sweat glands. Conclusions: The pathobiology of cutaneous lupus involves not only the epidermis, but also dermal pilosebaceous units, eccrine sweat glands and blood vessels. Further studies are recommended, especially in the light of presented data regarding T cell activation and proapototic molecules.

    Full Text Available We present a case of an 18-year-old male patient who, after two years of inappropriate treatment for cutaneous leishmaniasis, began to show nodules arising at the edges of the former healing scar. He was immune competent and denied any trauma. The diagnosis of recurrent cutaneous leishmaniasis was made following positive culture of aspirate samples. The patient was treated with N-methylglucamine associated with pentoxifylline for 30 days. Similar cases require special attention mainly because of the challenges imposed by treatment.Paciente do sexo masculino, 18 anos. Dois anos após tratamento insuficiente para leishmaniose tegumentar americana, apresentou, na mesma localização, lesão formada por cicatriz atrófica central e nódulos verrucosos na periferia. Era imunocompetente, hígido e negava qualquer trauma local. O diagnóstico de leishmaniose recidiva cutis foi feito através de cultura do aspirado da lesão. Realizou tratamento com N-metilglucamina (20mgSbV/kg/dia associado à pentoxifilina (1200mg/dia durante 30 dias alcançando cura clínica.

    Cutaneous regeneration utilizes paracrine feedback mechanisms to fine-tune the regulation of epidermal keratinocyte proliferation and migration. However, it is unknown how fibroblast-derived hepatocyte growth factor (HGF) affects these mutually exclusive processes in distinct cell populations. We here show that HGF stimulates the expression and phosphorylation of the microtubule-destabilizing factor stathmin in primary human keratinocytes. Quantitative single cell- and cell population-based analyses revealed that basal stathmin levels are important for the migratory ability of keratinocytes in vitro; however, its expression is moderately induced in the migration tongue of mouse skin or organotypic multi-layered keratinocyte 3D cultures after full-thickness wounding. In contrast, clearly elevated stathmin expression is detectable in hyperproliferative epidermal areas. In vitro, stathmin silencing significantly reduced keratinocyte proliferation. Automated quantitative and time-resolved analyses in organotypic cocultures demonstrated a high correlation between Stathmin/phospho-Stathmin and Ki67 positivity in epidermal regions with proliferative activity. Thus, activation of stathmin may stimulate keratinocyte proliferation, while basal stathmin levels are sufficient for keratinocyte migration during cutaneous regeneration.

    BRAF inhibitors are highly effective therapies for the treatment of BRAFV600-mutated melanoma, with the main toxicity being a variety of hyperproliferative skin conditions due to paradoxical activation of the mitogen-activated protein kinase (MAPK) pathway in BRAF wild-type cells. Most of these hyperproliferative skin changes improve when a MEK inhibitor is co-administered, as it blocks paradoxical MAPK activation. Here we show how the BRAF inhibitor vemurafenib accelerates skin wound healing by inducing the proliferation and migration of human keratinocytes through extracellular signal-regulated kinase (ERK) phosphorylation and cell cycle progression. Topical treatment with vemurafenib in two wound-healing mice models accelerates cutaneous wound healing through paradoxical MAPK activation; addition of a mitogen-activated protein kinase kinase (MEK) inhibitor reverses the benefit of vemurafenib-accelerated wound healing. The same dosing regimen of topical BRAF inhibitor does not increase the incidence of cutaneous squamous cell carcinomas in mice. Therefore, topical BRAF inhibitors may have clinical applications in accelerating the healing of skin wounds. PMID:27476449

  11. Leishmaniasis recidivans in Ethiopia: cutaneous and mucocutaneous features. (United States)

    Dassoni, Federica; Daba, Frehiwot; Naafs, Bernard; Morrone, Aldo


    Cutaneous leishmaniasis (CL) is endemic in Ethiopia. An unusual clinical form of this disease is leishmaniasis recidivans (LR), a prolonged, relapsing form of cutaneous leishmaniasis resembling tuberculosis of the skin that may persist for many years with a chronic and relapsing course. This rare variant has been shown to be caused by Leishmania tropica species in the Old World and by Leishmania braziliensis, Leishmania amazonensis, Leishmania panamensis, and Leishmania guyanensis in the New World, as reported in various studies. To our knowledge, there are no reports from Ethiopia, and mucocutaneous involvement of LR has not been described to date. This was a retrospective analysis of the patients seen at the Italian Dermatological Center in Mekelle on the Tigrean highlands over a three-year period (2008-2011). Seven patients with typical clinical features of LR were seen. Two of them presented with signs of mucosal involvement. To date, Leishmania aethiopica is shown to be the only species causing CL that is endemic in the Ethiopian highlands. Therefore, it had to be assumed that the lesions in these patients were caused by this species. The aims of this communication are to report, for the first time, the presence of LR, most likely due to Leishmania aethiopica, in Ethiopia, and to report mucosal involvement in this rare clinical form of CL.

  12. Metastatic Tumor Dormancy in Cutaneous Melanoma: Does Surgery Induce Escape?

    Tseng, William W. [Department of Surgery, University of California at San Francisco, 513 Parnassus Avenue, Room S-321, San Francisco, CA 94143 (United States); Fadaki, Niloofar; Leong, Stanley P., E-mail: [Department of Surgery and Center for Melanoma Research and Treatment, California Pacific Medical Center and Research Institute, 2340 Clay Street, 2nd floor, San Francisco, CA 94115 (United States)


    According to the concept of tumor dormancy, tumor cells may exist as single cells or microscopic clusters of cells that are clinically undetectable, but remain viable and have the potential for malignant outgrowth. At metastatic sites, escape from tumor dormancy under more favorable local microenvironmental conditions or through other, yet undefined stimuli, may account for distant recurrence after supposed “cure” following surgical treatment of the primary tumor. The vast majority of evidence to date in support of the concept of tumor dormancy originates from animal studies; however, extensive epidemiologic data from breast cancer strongly suggests that this process does occur in human disease. In this review, we aim to demonstrate that metastatic tumor dormancy does exist in cutaneous melanoma based on evidence from mouse models and clinical observations of late recurrence and occult transmission by organ transplantation. Experimental data underscores the critical role of impaired angiogenesis and immune regulation as major mechanisms for maintenance of tumor dormancy. Finally, we examine evidence for the role of surgery in promoting escape from tumor dormancy at metastatic sites in cutaneous melanoma.

  14. Toxic epidermal necrolysis: a severe cutaneous adverse drug reaction

    K. N. Chidananda


    Full Text Available Toxic epidermal necrolysis (TEN is a rare but serious is a rare but potentially life-threatening condition. It is primarily a cutaneous reaction to various precipitating agents, characterized by wide spread erythema and detachment of the epidermis from the dermis. Among the various cutaneous adverse drug reactions, TEN occupy a primary place in terms of mortality. In TEN large sheets of skin are lost from the body surface, thereby decreasing the protecting function of the skin, which results in complications. Usually, TEN is self-limited in absence of complications. If complicated by sepsis, there will be increased chances of mortality. The main treatment would be cessation of the causative drug and early admission of the patient for supportive care and minimizing the occurrence of complications. The present articles reviews the etiology, pathophysiology, differential diagnosis and treatment protocol, with a case of TEN occurrence in a child of 4 years age after consuming phenytoin syrup for febrile convulsions.

  15. Cutaneous Vasculopathy Associated with Levamisole-Adulterated Cocaine (United States)

    Tran, Huy; Tan, Debbie; Marnejon, Thomas P.


    We report a case of cutaneous vasculopathy associated with the use of levamisole-adulterated cocaine. This recently described clinical entity is characterized by a purpuric rash with a predilection for the ears, leukopenia, and anti-neutrophilic cytoplasmic antibody (ANCA) positivity. It is estimated that more than 70% of the current United States cocaine supply is contaminated with levamisole. Levamisole is a widely available, inexpensive, white powder used as a “cutting agent” in cocaine to expand volume and increase profits. It may also increase the euphoric and stimulatory effects of cocaine by increasing brain dopamine levels and producing amphetamine-like metabolites. Our patient exhibited a characteristic rash with involvement of the ears, leukopenia, and cocaine metabolites were detected in serum and urine. The presence of levamisole was confirmed in the urine utilizing gas chromatography-mass spectrometry. ANCA positivity was also present. Punch biopsy of the skin demonstrated vascular thrombosis and necrosis without true vasculitis. We review the literature for reported cases of cocaine-levamisole cutaneous vasculopathy syndrome, highlight the salient immunologic abnormalities, and contrast the features of this entity with idiopathic systemic vasculitis.

  16. Initial cutaneous manifestations of Hutchinson-Gilford progeria syndrome. (United States)

    Rork, Jillian F; Huang, Jennifer T; Gordon, Leslie B; Kleinman, Monica; Kieran, Mark W; Liang, Marilyn G


    Hutchinson-Gilford progeria syndrome (HGPS) is a rare, uniformly fatal, premature aging disease with distinct dermatologic features. We sought to identify and describe the initial skin and hair findings as potential diagnostic signs of the disease. We performed a chart review of the structured initial intake histories of 39 individuals with HGPS enrolled in clinical trials from 2007 to 2010 at Boston Children's Hospital, limited to cutaneous history from birth to 24 months. Medical photographs were provided through the clinical trials and the Progeria Research Foundation Medical and Research Database at Brown University Center for Gerontology and Healthcare Research. All 39 patients reported skin and hair abnormalities within the first 24 months of life. Pathologies included sclerodermoid change, prominent superficial veins, dyspigmentation, and alopecia. The mean age of presentation for each finding was <12 months. The most frequently reported skin feature was sclerodermoid change, which commonly involved the abdomen and bilateral lower extremities. Prominent superficial vasculature manifested as circumoral cyanosis and pronounced veins on the scalp and body. Hypo- and hyperpigmentation were observed over areas of sclerodermoid change. Scalp alopecia progressed in a distinct pattern, with preservation of the hair over the midscalp and vertex areas for the longest period of time. HGPS has distinct cutaneous manifestations during the first 2 years of life that may be the first signs of disease. Awareness of these findings could expedite diagnosis.

  17. Adverse cutaneous reactions induced by exposure to woods

    Directory of Open Access Journals (Sweden)

    Dorota Chomiczewska-Skóra


    Full Text Available Various adverse cutaneous reactions may occur as a result of exposure to wood dust or solid woods. These include allergic contact dermatitis, irritant contact dermatitis and, more rarely, contact urticaria, photoallergic and phototoxic reactions. Also cases of erythema multiforme-like reactions have been reported. Contact dermatitis, both allergic and irritant, is most frequently provoked by exotic woods, e.g. wood of the Dalbergia spp., Machaerium scleroxylon or Tectona grandis. Cutaneous reactions are usually associated with manual or machine woodworking, in occupational setting or as a hobby. As a result of exposure to wood dust, airborne contact dermatitis is often diagnosed. Cases of allergic contact dermatitis due to solid woods of finished articles as jewelry or musical instruments have also been reported. The aim of the paper is to present various adverse skin reactions related to exposure to woods, their causal factors and sources of exposure, based on the review of literature.

    Sorenson, Richard D.


    Administrative power for some school teachers can be an aphrodisiac that can be applied negatively, especially when a leader has devastating instinct for the weaknesses of others. A leader's intellect and heart closes shop and ceases to function when drunk on power. In this article, the author describes how the use of administrative power can be…
