    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 (BH4) 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 BH4 administration or argi...

  3. Distribution and excretion of a new insect repellent, 14C-DEM, in the mouse after intravenous, cutaneous, and oral administration

    International Nuclear Information System (INIS)

    The distribution of 14C after administration of 14C-DEM was qualitatively similar irrespective of the administration route (intravenous, cutaneous or oral). The major accumulation sites were lacrimal and nasal glands, parotis, liver, and kidney. The main excretion was through the urine and only minor quantities through the faeces and the expired gases. It could be confirmed that the new repellent had a low skin uptake. (author)

    Nitric oxide (NO) increases cutaneous blood flow; however, the underpinning mechanism(s) remains to be elucidated. We hypothesized that the cutaneous blood flow response during intradermal administration of sodium nitroprusside (SNP, a NO donor) is regulated by calcium-activated potassium (KCa) channels and cyclooxygenase (COX) in young adults. We also hypothesized that these contributions are diminished in older adults given that aging can downregulate KCa channels and reduce COX-derived vasodilator prostanoids. In 10 young (23 ± 5 yr) and 10 older (54 ± 4 yr) adults, cutaneous vascular conductance (CVC) was measured at four forearm skin sites infused with 1) Ringer (Control), 2) 50 mM tetraethylammonium (TEA), a nonspecific KCa channel blocker, 3) 10 mM ketorolac, a nonspecific COX inhibitor, or 4) 50 mM TEA + 10 mM ketorolac via intradermal microdialysis. All skin sites were coinfused with incremental doses of SNP (0.005, 0.05, 0.5, 5, and 50 mM each for 25 min). During SNP administration, CVC was similar at the ketorolac site (0.005-50 mM, all P > 0.05) relative to Control, but lower at the TEA and TEA + ketorolac sites (0.005-0.05 mM, all P 0.05). Furthermore, TEA alone did not modulate CVC during any concentration of SNP administration in older adults (all P > 0.05). We show that during low-dose NO administration (e.g., 0.005-0.05 mM), KCa channels contribute to cutaneous blood flow regulation in young adults; however, in older adults, COX inhibition increases cutaneous blood flow through a KCa channel-dependent mechanism.

    International Nuclear Information System (INIS)

    The study of boron neutron capture therapy (BNCT) for malignant melanoma was initiated by Y. Mishima and his associates. Following basic research of 13 years, this team started the first clinical trial of cutaneous melanoma BNCT using 10B-para-boronophenylalanine (BPA) in 1985. Since then, 32 patients have been treated. We developed the following regimen for BNCT of malignant melanoma: 1) 170 - 250 mg/kg of BPA-fructose complex is administered by drip infusion over 3-hours. 2) The minimum dose for melanoma control by single irradiation is assumed to be 25 Gy-eq. 3) The maximum tolerable dose to the skin by single irradiation is assumed to be 18 Gy-eq. 4) As the therapeutic dose, the maximum tolerable dose to the skin itself is chosen. We report the clinical results of two patients with cutaneous melanoma treated by BNCT. We believe that cutaneous melanoma are suitable for BNCT and that the excellent results will have a great impact on patients in QOL. (author)

    Full Text Available We report a case of cutaneous angiomyolipoma (AML found on the anterior abdominal wall of a 3-year-old female child. Histologic examination showed a well-circumscribed nodule in the dermis composed of an intimate mixture of convoluted thick-walled blood vessels, smooth muscle, and mature fat. This lesion differs from renal AML in terms of a lack of association with tuberous sclerosis, circumscription, absence of epithelioid cells, and male predominance. We concluded that the unique features of this lesion distinguish it from other lesions such as angiomyoma, angiolipoma, myolipoma, haemangioma, and other mixed mesenchymal tumors. This case report suggests that the features considered diagnostic of AML can occur in extrarenal sites and, therefore, this diagnosis cannot be excluded on the basis of site alone.

    Recent findings regarding the topical application of liposomes are reviewed under 3 headings: (1) keratinocyte cultures, (2) animal experiments, and (3) clinical studies. Under cell culturing conditions, liposomes are able to get into direct contact with living keratinocytes--just as in cutaneous application when the barrier of the horny layer is missing (i.e. in case of superficial skin defects or unkeratinized mucocutaneoaus surfaces). Under these circumstances, keratinocytes show liposomal alterations of the cell structure, proliferation, and lipid fluidity. Animal experiments and clinical studies have pointed out that, in comparison with a conventional formulation, a liposomal way of application can enhance the penetration of various substances as well as their toposelective enrichment in the skin, since the dermal-vascular absorption is diminished.

    International Nuclear Information System (INIS)

    To determine the efficacy of oral Miltefosine in patients with cutaneous leishmaniasis and its comparison with the most effective standard treatment, pentavalent antimony compound. Thirty patients, 12 years of age or older clinically and histopathologically diagnosed as cutaneous leishmaniasis were selected. Fifteen patients received orally administered Miltefosine 2.5mg/kg/day for 28 days and remaining 15 received injectable pentavalent antimony 20mg/kg/day for 28 days. Pre-treatment complete physical examination was done along with necessary laboratory investigations in all cases. These were repeated again after 2 weeks and at the end of treatment to note any deviation from the normal limits. Groups were almost matched in terms of age, weight, parasitological score. The efficacy was evaluated by ulcer size, before therapy, at 2 weeks and 4 weeks. Patients were followed-up at 3 and 6 months. Efficacy of two groups was statistically compared by calculating p-value by z-test. All patients completed the study without any serious complication. Lesions improved significantly and only scarring and post-inflammatory pigmentation was left. At 3 months, cure rate was 93% in group A and it was 73.33% in group B while at the end of 6 months, it was 86% and 66.6% respectively. This difference between efficacies of two groups was not found to be statistically significant (p-value >0.5). Miltefosine appears to be a safe and effective alternative to currently used therapies. The striking advantage of Miltefosine is its oral administration and it may also be helpful in regions where parasites are resistant to current agents. (author)

    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.

    Life-threatening and benign drug reactions occur frequently in the skin, affecting 8 % of the general population and 2-3 % of all hospitalized patients, emphasizing the need for physicians to effectively recognize and manage patients with drug-induced eruptions. Neurologic medications represent a vast array of drug classes with cutaneous side effects. Approximately 7 % of the United States (US) adult population is affected by adult-onset neurological disorders, reflecting a large number of patients on neurologic drug therapies. This review elucidates the cutaneous reactions associated with medications approved by the US Food and Drug Administration (FDA) to treat the following neurologic pathologies: Alzheimer disease, amyotrophic lateral sclerosis, epilepsy, Huntington disease, migraine, multiple sclerosis, Parkinson disease, and pseudobulbar affect. A search of the literature was performed using the specific FDA-approved drug or drug classes in combination with the terms 'dermatologic,' 'cutaneous,' 'skin,' or 'rash.' Both PubMed and the Cochrane Database of Systematic Reviews were utilized, with side effects ranging from those cited in randomized controlled trials to case reports. It behooves neurologists, dermatologists, and primary care physicians to be aware of the recorded cutaneous adverse reactions and their severity for proper management and potential need to withdraw the offending medication.

    Tuberculosis continues to draw special attention from health care professionals and society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity, environmental factors and the type of inoculum, it may present varied clinical and evolutionary aspects. Patients with HIV and those using immunobiological drugs are more prone to infection, which is a great concern in centers where the disease is considered endemic. This paper aims to review the current situation of cutaneous tuberculosis in light of this new scenario, highlighting the emergence of new and more specific methods of diagnosis, and the molecular and cellular mechanisms that regulate the parasite-host interaction.

We sought to determine if chitosan, a polymer of deacetylated chitin, could be used as a potential treatment against these bacteria. We found that higher molecular weight chitosan had superior antimicrobial properties compared to lower molecular weights, and that this activity occurred in a pH dependent manner. Electron and fluorescence microscopy revealed that chi...

  1. Cutaneous lymphoid hyperplasias.

    2000-06-01

    Benign hyperplastic lymphoid infiltrates of the skin (pseudolymphoma, older term) simulate lymphoma clinically and histologically. They can be divided into B-cell predominant (typical cutaneous lymphoid hyperplasia (CLH), angiolymphoid hyperplasia, Kimura's disease, and Castleman's disease) and T-cell predominant (T-cell CLH, lymphomatoid contact dermatitis, and lymphomatoid drug eruption). Both types may represent exaggerated reactions to diverse external antigens (insect bite, tattoo, zoster, trauma, among others). A composite assessment of clinical presentation and behavior, routine histology, immunophenotyping, and molecular studies is essential for the diagnosis of benign cutaneous lymphoid infiltrates. Treatment includes antibiotics, intralesional and systemic corticosteroids, excision, radiotherapy, and immunosuppressants. Treatment depends on the assessment and biologic behavior, which is usually benign. Molecular biologic analysis has shown that a significant proportion of cases harbor occult B- or T-cell clones (clonal CLH). Progression to overt cutaneous lymphoma has been observed in a minority of cases. Patients with clonal populations of B or T cells and persistent lesions should be closely observed for emergence of a lymphoma. PMID:10892716

  2. Stem Cells for Cutaneous Wound Healing

    2015-01-01

    Full Text Available Optimum healing of a cutaneous wound involves a well-orchestrated cascade of biological and molecular processes involving cell migration, proliferation, extracellular matrix deposition, and remodelling. When the normal biological process fails for any reason, this healing process can stall resulting in chronic wounds. Wounds are a growing clinical burden on healthcare systems and with an aging population as well as increasing incidences of obesity and diabetes, this problem is set to increase. Cell therapies may be the solution. A range of cell based approaches have begun to cross the rift from bench to bedside and the supporting data suggests that the appropriate administration of stem cells can accelerate wound healing. This review examines the main cell types explored for cutaneous wound healing with a focus on clinical use. The literature overwhelmingly suggests that cell therapies can help to heal cutaneous wounds when used appropriately but we are at risk of clinical use outpacing the evidence. There is a need, now more than ever, for standardised methods of cell characterisation and delivery, as well as randomised clinical trials.

    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.

    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.

    Cutaneous angiosarcoma is probably the most malignant neoplasm involving the skin. Three clinical variants of cutaneous angiosarcoma are recognized, including angiosarcoma of the scalp and face of elderly patients, angiosarcoma associated with chronic lymphedema, and postirradiation angiosarcoma. Histopathologically, these three variants of angiosarcoma show similar features, which consist of poorly circumscribed, irregularly dilated, and anastomosing vascular channels lined by prominent endothelial cells that dissect through the dermis. Focally, neoplastic endothelial cells show large, hyperchromatic, and pleomorphic nuclei, protruding within vascular lumina and creating small papillations. Usually, inflammatory infiltrate is sparse and consists of a patchy, perivascular lymphoid infiltrate around the neoformed vessels. In rare instances, cutaneous angiosarcomas may exhibit prominent inflammatory infiltrate, and the neoplasm may be mistaken for an inflammatory process, both from clinical and histopathologic points of view. We describe four examples of cutaneous angiosarcomas with dense lymphocytic infiltrates involving the neoplasm. Immunohistochemically, lymphocytes expressed immunoreactivity for CD3, CD5, and CD45 markers, whereas the germinal centers were positive for CD20, CD79a, and Bcl-6. The neoplastic endothelial cells expressed immunoreactivity for the CD31, CD34, podoplanin, Prox-1, Lyve-1, and D2-40. We discuss the possible relationship between neoplastic endothelial lymphatic cells and reactive lymphocytes. Cutaneous angiosarcoma with prominent lymphocytic infiltrate may be readily mistaken for cutaneous follicle center cell lymphoma or cutaneous pseudolymphoma. PMID:17667166

    Full Text Available Leishmaniasis is a major world health problem, which is increasing in incidence. In Northern Europe it is seen in travellers returning from endemic areas. The protozoa is transmitted by sandflies and may produce a variety of clinical syndromes varying from a simple ulcer to fatal systemic disease. This review considers the management of simple cutaneous leishmaniasis. Patients usually have a single ulcer that may heal spontaneously, requiring only topical, or no treatment at all. Lesions caused by Leishmania braziliensis may evolve into the mucocutaneous form, ′espundia′, and should be treated with systemic antimony. Sodium stibogluconate 20mg/kg/day i.v. for 20 days is the appropriate first line treatment in these cases. Although it may cause transient bone marrow suppression, liver damage, a chemical pancreatitis, and disturbances in the electrocardiogram, it appears safe. The success of treatment should be assessed 6 weeks after it has been completed and patients should be followed up for 6 months.

    Full Text Available Importance. Cutaneous and systemic plasmacytosis are rare conditions of unknown etiology with characteristic red-brown skin lesions and a mature polyclonal plasma cell infiltrate within the dermis. Perineural plasma cell infiltrates may be a histologic clue to the diagnosis of cutaneous plasmacytosis. Observations. Our patient had a five-year history of persistent reddish-brown plaques on the neck and trunk without systemic symptoms. Histologic examination showed dermal perivascular and perineural plasma cells with excess lambda light chain expression. Due to decreased quality of life caused by his skin lesions, he was placed on a chemotherapeutic regimen with bortezomib. Conclusions and Relevance. The patient was diagnosed with cutaneous plasmacytosis based on classic histopathology results with a recently characterized pattern of perineural involvement. Bortezomib therapy was initiated to manage his skin eruption, which has not been previously described as a treatment for this chronic condition.

    RNase 7 belongs to the RNase A superfamily and exhibits a broad spectrum of antimicrobial activity against various microorganisms. RNase 7 is expressed in human skin, and expression in keratinocytes can be induced by cytokines and microbes. These properties suggest that RNase 7 participates in innate cutaneous defense. In this review, we provide an overview about the role of RNase 7 in cutaneous defense with focus on the molecular mechanism of the antimicrobial activity of RNase 7, the regulation of RNase 7 expression, and the role of RNase 7 in skin diseases.

In spite of what the name suggests, microemulsions are nanocarriers, and their use as topical delivery systems derives from their multiple advantages compared to other dermatological formulations, such as ease of preparation, thermodynamic stability and penetration-enhancing properties. Composition, charge and internal structure have been reported as determinant factors for the modulation of drug release and cutaneous and transdermal transport. This manuscript aims at reviewing how these and other characteristics affect delivery and make microemulsions appealing for topical and transdermal administration, as well as how they can be modulated during the formulation design to improve the potential and efficacy of the final system.

    Ultraviolet radiation (UVR) present in sunlight is a major environmental factor capable of affecting human health and well being. The organ primarily affected by UVR is the skin, which is composed of a variety of different cell types. Here, UVR is needed for production of active vitamin D as well as producing undesirable effects such as sunburn, premature cutaneous photoaging, and promoting skin cancer development. Depending on the radiation dose, UVR influences virtually every cutaneous cell type investigated differently. Since the end of the nineteenth century, sun exposure has been known to induce skin cancer, which is now the human malignancy with the most rapidly increasing incidence. In several experimental models, mid-range UVR has been demonstrated to be the major cause of UV-induced cutaneous tumors. The stratospheric ozone layer protecting the terrestrial surface from higher quantum energy solar radiation is being damaged by industrial activities resulting in the possibility of increased UVR exposure in the future. Investigations in the field of experimental dermatology have shown that within the skin an immunosurveillance system exists that may be able to detect incipient neoplasms and to elicit a host responses against it. This article reviews the literature on studies designed to investigate the effects of UVR on cutaneous cellular components, with special focus on the immune system within the skin and the development of UV-induced cancer.

    Cutaneous lymphomas represent a unique group of lymphomas and are the second most frequent extranodal lymphomas. As with other neoplasias, the pathogenesis is based mainly on a stepwise accumulation of mutations of suppressor genes and oncogenes caused by genetic, environmental or infectious factors. The diagnostic work-up includes clinical, histological, imaging and hematological investigations and in many cases immunohistochemical and molecular biological analyses. The current WHO/EORTC classification of cutaneous lymphomas differentiates "mature T-cell and NK-cell lymphomas", "mature B-cell lymphomas" and "immature hematopoietic malignancies", their variants and subgroups. It is compatible with the WHO classification for neoplasias of the hematopoietic and lymphoid tissue and respects the organ-specific peculiarities of primary cutaneous lymphomas. The assignment of the various types of cutaneous lymphomas into prognostic categories (pre-lymphomatous "abortive" disorders; definite malignant lymphomas of low-grade malignancy; definite malignant lymphomas of high-grade malignancy) provides essential information on the biological behavior and allows an appropriate planning of the therapeutic strategy, which may be topical or systemic and aggressive or non-aggressive. Besides the classical options for therapy, there are new and "experimental" strategies, the efficacy of which has to be studied in clinical trials. PMID:17081267

    Chemicals have become indispensible for the maintenance of health in animals and man. The route of administration of each medicament is decided by factors such as site of desired action, chemistry of the active ingredient, age and species of the patient, and frequency of administration (or desired duration of activity). In situations where the oral and hypodermic routes, which are used most frequently, are inadequate or unsatisfactory, dermal application can provide a valuable alternative method to achieve systemic activity. Examples of formulations currently available for dermal application contain diverse chemicals and are intended for a variety of purposes, such as crufomate against cattle grubs, fenthion against cattle lice, levamisole against gastrointestinal nematodes, nitroglycerine for angina pectoris, and scopolamine for motion sickness. The skin acts as a barrier to penetration by chemicals and micro-organisms by virtue of its morphology and chemical composition. Chemicals which do penetrate, do not necessarily pass through the appendages (hair follicles and gland ducts), but mostly penetrate through the interjacent epidermis, either through the cells, or via the intracellular spaces. These spaces have recently been shown by electron microscopy to be filled by an amorphous substance which exudes on the skin surface in convex ridges. This substance has a lipid nature, but is not hydrophobic as is often accepted. For a chemical to be able to penetrate the skin, it must be partially water and lipid soluble, polar, and weakly ionizing. A variety of factors can possibly affect the permeability of skin for a chemical. These include species differences in morphology (skin thickness, tightness of intercellular junctions, density of hair follicles and other appendages), biochemistry, and physiology; seasonal and climatic variations; and differences between breeds and genders. Species differences in skin permeability are largely unpredictable and inconsistent. An

    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.

    In Mexico, 6 cases of diffuse cutaneous leishmaniasis (DCL) were found in widely separated geographic regions. Information was also available on 2 other cases. In addition to the typical clinical features, half of the patients had evidence of nasopharyngeal mucosal involvement. All isolates from the DCL patients were identified as Leishmania mexicana mexicana by isoenzyme analysis and monoclonal antibody typing. In 1 region of Tabasco state where DCL was found, uncomplicated cutaneous leishmaniasis appeared to be highly endemic, and isolates from a few such patients were identified as L. mexicana mexicana. An incidental finding was the recovery of an isolate of L. braziliensis braziliensis from a patient with chiclero ulcer in Oaxaca state.

Contrary to other reports, this case demonstrates that a good response with standard therapy is possible.

    Background Cutaneous hyperpigmentation is an often overlooked clinical sign in megaloblastic anemia (MA) which has been sporadically reported in the literature. Methods We describe the bone marrow (BM) changes and clinicolaboratory characteristics of 25 of 198 adult cases (>16 years) with cutaneous hyperpigmentation who underwent BM evaluation for cytopenia (s). Results Twenty-one of 25 cases (84%) had MA, while MA without hyperpigmentation occurred only in 12 of remainder 173 cases (P0.05). In six cases where follow-up data were available, there was a significant reversal of hyperpigmentation at 12 weeks following parenteral cobalamin therapy. In all five cases with pyrexia, fever subsided after 24 to 72 hours following administration of parenteral cobalamin therapy. Conclusion Cutaneous hyperpigmentation and cytopenia (s) are strongly associated with megaloblastic anemia. Knuckle pad hyperpigmentation is much more frequent than diffuse pigmentation of the palms and/or soles in such patents. A nonsignificant trend towards a greater degree of MA was found in cases with pigmentation of the knuckles. PMID:27158434

    A male golden retriever of unknown age presented with multiple cutaneous and subcutaneous masses from the left elbow to the digits. Histopathologically, multiple tumor foci had formed from the dermis to the subcutaneous tissue. Tumor foci consisted of a vascular structure, alveolar structure and solid proliferative area. The borders among these areas were not clear. Some neoplastic cells resembled a mature endothelium, while others were large pleomorphic cells. Immunohistochemically, the tumor cells were usually strongly positive for CD31 and often positive for PROX-1, the lymphatic endothelial cell marker. Based on these findings, the tumor was diagnosed as a hemangiosarcoma with lymphatic differentiation. PMID:23914061

    2009-04-01

    The known spectrum of skin manifestations in cutaneous Lyme disease is continuously expanding and can not be regarded as completed. Besides the classical manifestations of cutaneous borreliosis like erythema (chronicum) migrans, borrelial lymphocytoma and acrodermatitis chronica atrophicans evidence is growing that at least in part also other skin manifestations, especially morphea, lichen sclerosus and cases of cutaneous B-cell lymphoma are causally related to infections with Borrelia. Also granuloma annulare and interstitial granulomatous dermatitis might be partly caused by Borrelia burgdorferi or similar strains. There are also single reports of other skin manifestations to be associated with borrelial infections like cutaneous sarcoidosis, necrobiosis lipoidica and necrobiotic xanthogranuloma. In addition, as the modern chameleon of dermatology, cutaneous borreliosis, especially borrelial lymphocytoma, mimics other skin conditions, as has been shown for erythema annulare centrifugum or lymphocytic infiltration (Jessner Kanof) of the skin.

  1. Selenium for the Prevention of Cutaneous Melanoma

    Directory of Open Access Journals (Sweden)

    Douglas Grossman

    2013-03-01

    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.

    2003-07-01

    A detailed anatomic study was carried out on the lateral femoral cutaneous nerve to better understand the etiology and treatment of lateral femoral cutaneous neuralgia. As it passed from the pelvis into the thigh, the lateral femoral cutaneous nerve ran through an "aponeuroticofascial tunnel," beginning at the iliopubic tract and ending at the inguinal ligament; as it passed through the tunnel, an enlargement in its side-to-side diameter was observed, suggesting that the fascial structures proximal to the inguinal ligament may be implicated in the genesis of lateral femoral cutaneous neuralgia. The finding of pseudoneuromas at this location, distant from the inguinal ligament, supports this hypothesis. The anterior superior iliac spine is located approximately 0.7 cm from the lateral femoral cutaneous nerve and serves as the bony landmark for nerve localization. Within the first 3 cm of leaving the pelvis, the lateral femoral cutaneous nerve was observed deep to the fascia lata; therefore, surgical dissection within the subcutaneous fascia may be conducted with relative impunity near the anterior superior iliac spine just inferior to the inguinal ligament. In 36% of cases there was no posterior branch of the nerve, which is correlated to lateral femoral cutaneous neuralgia symptoms often being limited to the anterior branch region. An accessory nerve was found in 30% of cases. PMID:12794914

    Full Text Available Inflammatory bowel diseases have a high frequency in Europe. They are chronic disorders that evolve with relapses and remissions. Clinical features include the signs of underlying inflammatory bowel disease and also signs of extraintestinal manifestations. Cutaneous disorders are the most common extraintestinal manifestations associated with inflammatory bowel diseases, which can be dependent on or independent of gastrointestinal disease activity. The main cutaneous disorders are erythema nodosum and pyodermagangrenosum. The pathogenic mechanisms are not fully understood but it seems that related mechanisms are involved in the development of inflammatory bowel diseases and extraintestinal manifestations. Treatment should be aimed at both the cutaneous manifestations and the bowel inflammation

    Alternariosis is a fungal infection that is usually described in immunocompromised patients. We report a case of cutaneous alternariosis in a renal transplant recipient caused by Alternaria tenuissima. The diagnosis was supported by histopathologic (ie, yeastlike cells, filamentous structures) and mycologic findings from a cutaneous biopsy. Cutaneous lesions regressed 1 month following a decrease in the dosage of immunosuppressive therapy. The patient also was treated with intravenous amphotericin B followed by oral fluconazole without improvement. Cryotherapy remarkably accelerated healing of the lesions. PMID:24897135

  8. [Niacin deficiency and cutaneous immunity].

    Science.gov (United States)

    Ikenouchi-Sugita, Atsuko; Sugita, Kazunari

    2015-01-01

    Niacin, also known as vitamin B3, is required for the synthesis of coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Niacin binds with G protein-coupled receptor (GPR) 109A on cutaneous Langerhans cells and causes vasodilation with flushing in head and neck area. Niacin deficiency due to excessive alcohol consumption, certain drugs or inadequate uptake in diet causes pellagra, a photosensitivity dermatitis. Recently several studies have revealed the mechanism of photosensitivity in niacin deficiency, which may pave a way for new therapeutic approaches. The expression level of prostaglandin E synthase (PTGES) is up-regulated in the skin of both pellagra patients and niacin deficient pellagra mouse models. In addition, pellagra is mediated through prostaglandin E₂-EP4 (PGE₂-EP4) signaling via reactive oxygen species (ROS) production in keratinocytes. In this article, we have reviewed the role of niacin in immunity and the mechanism of niacin deficiency-induced photosensitivity. PMID:25765687

    Arfa, Kenneth S.

    2016-01-01

    Background: Ferrofluid is a colloidal suspension that usually consists of surfactant-coated nanoparticles of magnetite (Fe3O4) in a carrier liquid. Ferromagnetic fluid forms spikes when the liquid is exposed to a magnetic field. Purpose: The authors describe a man who developed temporary discoloration of his right palm and fingers after accidental cutaneous contact with ferrofluid and discuss some of the current and potential applications of this unique liquid. Methods: A 28-year-old man was evaluating the effects of magnetic fields using ferrofluid. He performed a modification of the “leaping ferrofluid” demonstration in which he held a superstrong (14,800 gauss magnetic field strength) N52 rare earth neodymium magnet in his palm and slowly lowered that hand over an open bowl that was filled with ferrofluid. Results: As the magnet approached the liquid, the ferrofluid became magnetized. The liquid leaped from the bowl and contacted not only the magnet, but also the palmar surface of his hand and fingers, resulting in a black-brown dyschromia of the affected skin. The discoloration completely resolved after two weeks without any adverse sequellae. Conclusion: Ferrofluid has numerous current and potential applications; in addition to being of value educationally and aesthetically (after being subjected to magnetic fields), it is also utilized for audio loudspeakers, medical innovations (such as a component of either a research tool, a diagnostic aid, or a treatment modality), and seals. Although the authors’ patient did not experience any acute or chronic toxicity from his cutaneous exposure to ferrofluid, conservative follow-up for individuals who experience skin contact with ferromagnetic fluid may be appropriate.

    The United States continues to be a prime target for attack by terrorist organizations in which nuclear detonation and dispersal of radiological material are legitimate threats. Such attacks could have devastating consequences to large populations, in the form of radiation injury to various human organ systems. One of these at risk organs is the cutaneous system, which forms both a physical and immunological barrier to the surrounding environment and is particularly sensitive to ionizing radiation. Therefore, increased efforts to develop medical countermeasures for treatment of the deleterious effects of cutaneous radiation exposure are essential. Interleukin-12 (IL-12) was shown to elicit protective effects against radiation injury on radiosensitive systems such as the bone marrow and gastrointestinal tract. In this article, we examined if IL-12 could protect the cutaneous system from a combined radiation injury in the form of sublethal total body irradiation and beta-radiation burn (β-burn) directly to the skin. Combined radiation injury resulted in a breakdown in skin integrity as measured by transepidermal water loss, size of β-burn lesion and an exacerbated loss of surveillant cutaneous dendritic cells. Interestingly, intradermal administration of IL-12 48 h postirradiation reduced transepidermal water loss and burn size, as well as retention of cutaneous dendritic cells. Our data identify IL-12 as a potential mitigator of radiation-induced skin injury and argue for the further development of this cytokine as a radiation countermeasure. PMID:25564716

    Nutritional deficiencies may be associated with a variety of cutaneous findings in children. This review emphasizes new developments relating to cutaneous findings of nutritional deficiencies. Zinc deficiency, acrodermatitis enteropathica, and acrodermatitis enteropathica-like eruptions are seen with a variety of conditions including cystic fibrosis, anorexia nervosa, and breastfeeding. Similar cutaneous findings not related to zinc deficiency may also occur with such metabolic disorders as methylmalonic aciduria, multiple carboxylase deficiency, essential fatty acid deficiency and other amino acid deficiencies. Vitamin K deficiency is associated with hemorrhagic disease of the newborn and coagulopathy. Vitamin A deficiency presents with a variety of systemic findings and distinctive dermatologic findings. Acute vitamin A deficiency may be seen in children infected with measles and is associated with more severe disease. The systemic and cutaneous findings of vitamin C deficiency, scurvy, are discussed. PMID:8374671

    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

    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.

  3. Cutaneous blood flow in psoriasis

    International Nuclear Information System (INIS)

    The disappearance rate of 133Xe was studied in 20 patients with psoriasis vulgaris, using an epicutaneous labeling technique in involved skin lesions or normal-appearing skin of the proximal extensor site of the forearm. Control experiments were performed in 10 normal subjects. Calculations of the cutaneous blood flow (CBF) in psoriatic skin lesions were performed using a tissue-to-blood partition coefficient for 133Xe, lambda c,pso, of 1.2 ml/100 g/min. lambda c,pso was estimated after the relative content of water, lipids, and proteins had been analyzed in psoriatic skin biopsies of 6 patients with untreated psoriasis. The mean relative content of water was markedly reduced to 23.5 +/- 1.5% (SEM), and lipids and proteins were markedly increased to 2.5 +/- 0.7% and 74.0 +/- 2.2, respectively, compared to previously published data for normal skin (water 72.5%, lipids 1%, proteins 26.5%). Mean CBF in untreated psoriatic skin was 63.5 +/- 9.0 ml/100 g/min. This was significantly higher than the mean CBF in 10 normal subjects, 6.3 +/- 0.5 ml/100 g/min (p much less than 0.0001). Mean CBF in normal-appearing skin in patients with psoriasis was 11.0 +/- 1.3 ml/100 g/min. This was significantly higher than CBF in normal subjects (p less than 0.0002)

    2008-05-01

    Vasculitis is characterized by an inflammatory reaction of vessel walls with damage to the dependent tissues. Forms of vasculitis which frequently have skin changes include leukocytoclastic angiitis (LcV), Henoch-Schönlein purpura (HSP), cutaneous polyarteriitis nodosum (cPAN), erythema elevatum et diutinum (EED) and urticarial vasculitis (UV). In other forms of vasculitis, systemic manifestations predominate but there are a variety of skin changes. Kawasaki disease (MK), cryoglobulinemic vasculitis (kV), Wegener granulomatosis (WG), Churg-Strauss syndrome (CSS) and microscopic polyangitis (MPA) belong to this group. The causes of vasculitis are heterogeneous. Triggers include infections, drugs, collagen vascular diseases, autoimmune diseases and lymphoproliferative disorders. Idiopathic vasculitis, particularly LcV and EED, occur only once and have a self-limited course. The diagnostic work up depends on the clinical picture and includes inflammatory markers, circulating immune complexes, different types of cryoglobulins and anti-neutrophilic cytoplasmic antibodies, collagen vascular disease specific autoantibodies and additional hematological studies. Vasculitis can manifest in many organs and requires a thorough work up specifically in cases where WG, MPA, CSS and PAN are under consideration. PMID:18415062

    Full Text Available Cutaneous epithelioid angiosarcoma is a rare malignant vascular tumor, most commonly affecting elderly men, and is usually located on the extremities. We report a case of an 81-year-old lady who presented with two ulcerated plaques over the right temporal and parietal scalp of 1 year duration. The right submaxillary and submandibular lymph nodes were enlarged and tender. Computed tomography (CT scan of the head showed soft tissue swelling over parietal and temporal areas and there was no intracranial extension. Ultrasonogram of the abdomen showed hyperechoic areas in liver suggestive of secondaries. Histopathology of the skin lesion showed the dermis and subcutis composed of clusters of atypical epithelioid cells with vesicular nuclei, prominent nucleoli and eosinophilic cytoplasm with increased mitotic figures. Immunohistochemical staining revealed CD-31, 33, 34 and vimentin positivity, while cytokeratin was negative confirming the diagnosis of epitheloid angiosarcoma. This case report highlights the unusual occurrence of multicentric epitheloid angiosarcoma on the scalp with secondaries in the liver.

    2003-02-10

    Eight cases of feline (muco)cutaneous mycobacteriosis were studied to identify the causative agent and examine for phenotype and functional characteristics (expression of interleukin (IL)-1beta, IL-6, IL-12, tumour necrosis factor-alpha and inducible nitric oxide synthase) of the inflammatory cells. Polymerase chain reaction and sequencing identified the causative agents as Mycobacterium tuberculosis or M. avium complex in each four cases. Lesions were characterised by pyogranulomatous infiltration, with variability in the presence and size of necrotic areas, the presence of multinucleated giant cells and the degree of lymphocyte infiltration. Macrophages were positive for myeloid/histiocyte antigen (calprotectin), suggesting they represented freshly recruited monocytes; further differentiation to epithelioid cells and multinucleated giant cells was associated with loss of the myeloid/histiocyte antigen. Lymphocytes were found disseminated in the infiltrate (predominantly T cells) and as B cell-dominated accumulations mainly in the periphery of the lesions. Acid-fast bacilli were numerous. In M. tuberculosis complex infection, extracellular bacilli were most prominent, whereas in M. avium complex infection, bacilli were mainly located intracellularly. All cytokines examined as well as inducible nitric oxide synthase (iNOS) were variably expressed by macrophages, epithelioid cells and multinucleated giant cells. Expression was most intense in degenerating macrophages loaded with intracellular bacilli, but was also seen cell-free within necrotic areas. The intense induction of cytokine and iNOS expression especially in infected macrophages suggests a relatively low virulence for these infectious agents in cats. Furthermore, the confinement of the bacilli to lesions indicates a successful response to infection. PMID:12586480

  7. Cutaneous interstitial nitric oxide concentration does not increase during heat stress in humans

    2001-01-01

    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 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.

    2003-01-01

    This study tested the hypothesis that head-down tilt bed rest (HDBR) reduces adrenergic and nonadrenergic cutaneous vasoconstrictor responsiveness. Additionally, an exercise countermeasure group was included to identify whether exercise during bed rest might counteract any vasoconstrictor deficits that arose during HDBR. Twenty-two subjects underwent 14 days of strict 6 degrees HDBR. Eight of these 22 subjects did not exercise during HDBR, while 14 of these subjects exercised on a supine cycle ergometer for 90 min a day at 75% of pre-bed rest heart rate maximum. To assess alpha-adrenergic vasoconstrictor responsiveness, intradermal microdialysis was used to locally administer norepinephrine (NE), while forearm skin blood flow (SkBF; laser-Doppler flowmetry) was monitored over microdialysis membranes. Nonlinear regression modeling was used to identify the effective drug concentration that caused 50% of the cutaneous vasoconstrictor response (EC(50)) and minimum values from the SkBF-NE dose-response curves. In addition, the effects of HDBR on nonadrenergic cutaneous vasoconstriction were assessed via the venoarteriolar response of the forearm and leg. HDBR did not alter EC(50) or the magnitude of cutaneous vasoconstriction to exogenous NE administration regardless of whether the subjects exercised during HDBR. Moreover, HDBR did not alter the forearm venoarteriolar response in either the control or exercise groups during HDBR. However, HDBR significantly reduced the magnitude of cutaneous vasoconstriction due to the venoarteriolar response in the leg, and this response was similarly reduced in the exercise group. These data suggest that HDBR does not alter cutaneous vasoconstrictor responses to exogenous NE administration, whereas cutaneous vasoconstriction of the leg due to the venoarteriolar response is reduced after HDBR. It remains unclear whether attenuated venoarteriolar responses in the lower limbs contribute to reduced orthostatic tolerance after bed rest and

    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.

    2012-02-01

    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.

    Besides their deleterious action on cardiac muscle, anthracycline-type cytostatic agents exert significant neurotoxic effects on primary sensory neurons. Since cardiac sensory nerves confer protective effects on heart muscle and share common traits with cutaneous chemosensitive nerves, this study examined the effects of cardiotoxic doses of adriamycin on the function and morphology of epidermal nerves. Sensory neurogenic vasodilatation, plasma extravasation, and the neural CGRP release evoked by TRPV1 and TRPA1 agonists in vitro were examined by using laser Doppler flowmetry, the Evans blue technique, and ELISA, respectively. Carrageenan-induced hyperalgesia was assessed with the Hargreaves method. Immunohistochemistry was utilized to study cutaneous innervation. Adriamycin treatment resulted in profound reductions in the cutaneous neurogenic sensory vasodilatation and plasma extravasation evoked by the TRPV1 and TRPA1 agonists capsaicin and mustard oil, respectively. The in vitro capsaicin-, but not high potassium-evoked neural release of the major sensory neuropeptide, CGRP, was markedly attenuated after adriamycin treatment. Carrageenan-induced inflammatory hyperalgesia was largely abolished following the administration of adriamycin. Immunohistochemistry revealed a substantial loss of epidermal TRPV1-expressing nociceptive nerves and a marked thinning of the epidermis. These findings indicate impairments in the functions of TRPV1 and TRPA1 receptors expressed on cutaneous chemosensitive nociceptive nerves and the loss of epidermal axons following the administration of cardiotoxic doses of adriamycin. Monitoring of the cutaneous nociceptor function in the course of adriamycin therapy may well be of predictive value for early detection of the deterioration of cardiac nerves which confer protection against the deleterious effects of the drug.

    International Nuclear Information System (INIS)

    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)

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

    Cutaneous metastases occur in up to 9% of all patients with cancer and may cause discomfort and stigmatization. Electrochemotherapy is a local treatment using electric pulses to permeabilize cell membranes, enabling chemotherapy, such as bleomycin, to enter the cells and increase the cytotoxic effect by at least 300-fold. Electrochemotherapy is an efficient, once only treatment for cutaneous metastases with an objective response of 62-99%. Electrochemotherapy can reduce discomfort such as ulceration, oozing, bleeding and pain. Adverse events depend on the size of treatment area, but are very limited. PMID:26321586

Each patient had a history of systemic allergic reactions to porcine insulin and was at least as reactive to human as to porcine insulin by end-point cutaneous titration. Both patients' insulin allergy was managed with animal insulins and both have done well. Our experience with these two patients indicates that human insulin (rDNA) should not be expected to be efficacious in all patients with systemic allergy to insulin. PMID:6366262

    Background Although cutaneous ulcers (CU) in the tropics is frequently attributed to Treponema pallidum subspecies pertenue, the causative agent of yaws, Haemophilus ducreyi has emerged as a major cause of CU in yaws-endemic regions of the South Pacific islands and Africa. H. ducreyi is generally susceptible to macrolides, but CU strains persist after mass drug administration of azithromycin for yaws or trachoma. H. ducreyi also causes genital ulcers (GU) and was thought to be exclusively tra...

    2016-01-01

    Poikiloderma-like cutaneous amyloidosis (PCA) is a rare variant of primary cutaneous amyloidosis. It was first described in 1929 and there are two clinical forms of PCA, the ordinary type and PCA syndrome. The characteristics of PCA include poikiloderma-like skin changes, lichenoid papules, blister formation, and cutaneous amyloid deposits on histological examination. These skin lesions usually occur at the extremities, consistent with the few cases that have been reported. We present a case of a 62-year-old man who presented with the features of poikiloderma-like cutaneous amyloidosis. Diagnosis of this unique condition is a challenge and a skin biopsy is necessary in such instances. A discussion of the differential diagnosis of this condition is also included. PMID:26990468

    Cutaneous pseudolymphomas are benign lymphoproliferative processes mimicking lymphomas clinically and histologically. One of the precipitating factors for pseudolymphoma is drugs like anticonvulsants, antidepressants and angiotensin-converting enzyme inhibitors. According to existing literature phenytoin-induced cutaneous pseudolymphomas are usually T-cell predominant. Most often withdrawal of the drug with or without short-course systemic steroids can attain a cure. Rarely malignant transformation has been reported years later despite withdrawal of the offending drug, which necessitates a long-term follow up of the affected. We report an 80-year-old male patient who was receiving phenytoin sodium and who presented with diffuse erythema and infiltrated skin lesions which histologically resembled cutaneous B-cell lymphoma. Substituting phenytoin with levetiracetam achieved resolution of symptoms. Further evaluation was suggestive of a reactive process. A detailed drug history is of paramount importance in differentiating drug-induced pseudolymphoma from lymphoma. Searching literature we could not find any previous reports of phenytoin-induced cutaneous B-cell pseudolymphoma. PMID:26538730

    International Nuclear Information System (INIS)

    Four cases of abnormally severe skin reactions including an instance of skin necrosis occurred in patients with breast cancer who were treated with cyclophosphamide, adriamycin and irradiation concurrently following mastectomy. These unusual skin reactions apparently resulted from the interaction of radiation with adriamycin and prompted us to modify both the radiation dose and the timing of administration of chemotherapy. To date, no unusual or severe skin reactions have been observed in 14 patients who have received chemotherapy with adriamycin plus radiation in accord with this modified treatment plan

  18. Acute Radiation Disease : Cutaneous Syndrome and Toxic properties of Radiomimetics -Radiation Neurotoxins and Hematotoxins.

    Popov, Dmitri; Maliev, Slava

    Cutaneous injury is an important complication of a general or local acute irradiation. A type of a skin and tissues lesions depends on a type, intensity, and period of irradiation. Also, the clinical picture, signs, and manifestations of the cutaneous syndrome depend on a type of the radiation toxins circulated in lymph and blood of irradiated mammals. Radiation Toxins were isolated from lymph of the mammals that were irradiated and developed different forms of the Acute Radiation Syndromes (ARS) -Cerebrovascular, Cardiovascular, Gastrointestinal, and Hematopoietic. Radiation Toxins can be divided into the two important types of toxins (Neu-rotoxins and Hematotoxins) or four groups. The effects of Radiation Neurotoxins include severe damages and cell death of brain, heart, gastrointestinal tissues and endothelial cells of blood and lymphatic vessels. The hematotoxicity of Hematotoxic Radiation Toxins includes lym-phopenia, leukopenia, thrombocytopenia, and anemia in the blood circulation and transitory lymphocytosis and leukocytosis in the Central Lymphatic System. In all cases, administration of the Radiomimetics (Radiation Toxins) intramuscularly or intravenously to healthy, radiation naive mammals had induced and developed the typical clinical manifestations of the ARS. In all cases, administration of Radiomimetics by subtoxic doses had demonstrated development of typical clinical signs of the cutaneous syndrome such as hair loss, erythema, swelling, desqua-mation, blistering and skin necrosis. In animal-toxic models, we have activated development of the local skin and tissue injury after injection of Radiation Toxins with cytoxic properties.

    Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis defined by heterogeneous multiorgan involvement. Due to the rarity of this disease strong evidence-based therapies have yet to be established and prognosis has previously been considered to be poor, with more than half of patients dying within 3 years of initial presentation. We describe an 86-year-old woman with a 34-year history of extensive cutaneous and internal nodules with typical pathological and immunophenotypical (CD68(+) /CD1a(-) ) features of ECD without evidence of the BRAF V600E mutation. The cosmetic appearance of cutaneous nodules and hoarse voice caused by vocal cord nodules has been managed surgically. More aggressive therapies reported for ECD were trialled for this patient, such as radiotherapy and interferon-α, with no response. This case demonstrates a relatively good prognosis in ECD that has been managed conservatively. PMID:25639756

Clinically, a diagnosis of chronic obstructive pulmonary disease (COPD with cutaneous lymphoma or soft tissue tumor was made. Chest X-ray (CXR and computed tomography (CT scan revealed a neoplastic lesion in the right lung with secondary cavitation. Biopsy of the cutaneous nodules showed metastatic deposits from squamous cell carcinoma. Metastatic skin cancer is a relatively rare complication of internal malignancy. The clinical features of metastatic skin disease vary enormously. They may present as erysipeloid, sclerodermoid, alopecia neoplastica or in an inflammatory or bullous form or as multiple nodules as in our case. A high index of suspicion for metastatic deposits is required in an elderly male patient who is a known case of lung cancer or even one who is a chronic smoker and presents with such cutaneous lesions.

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.

    Cutaneous leishmaniasis of the New World, in particular when caused by Leishmania (L.) braziliensis, harbours the risk of lymphogenic as well as hematogenic dissemination. This may result in mucocutaneous leishmaniasis causing severe destruction of orofacial structures. Dissemination may occur years after the disappearance of the skin lesions. In contrast, cutaneous leishmaniasis of the old world, is typically restricted to the site of inoculation. Therefore, a conservative diagnostic and therapeutic approach is usually sufficient. Infections acquired in the new world should be treated systemically, if infection with Leishmania (Viannia) braziliensis complex cannot be excluded. Here we report on three Austrian soldiers, who, weeks after having participated in an international jungle patrol course in Belize, presented themselves with multiple ulcers on the upper limbs. Diagnosis of cutaneous leishmaniasis was made based upon histological evaluation of biopsies taken from several ulcers revealing the presence of leishmanial bodies, and detection of amastigote leishmania in smears of material obtained from the ulcers. As species phenotyping could not be performed, infection with L. brasiliensis as well as progression into a mucocutaneous form were possible, demanding systemic therapy. Several treatment options including local cryotherapy with liquid nitrogen, paromomycin (Humatis Pulvis, Parke-Davis) 15% topically or oral fluconazole (Diflucan, Pfizer) 200 mg/d were applied, but showed no effect. Hence, a systemic therapy with intravenous pentamidine (Pentacarinat, Gerot), three times in total, 3-4 mg/kg body weight each, led to a complete regression of the lesions within four weeks.

    Cutaneous findings are not uncommonly a concomitant finding in patients afflicted with gastrointestinal (GI) diseases. The dermatologic manifestations may precede clinically evident GI disease. Part I of this 2-part CME review focuses on dermatologic findings as they relate to hereditary and nonhereditary polyposis disorders and paraneoplastic disorders. A number of hereditary GI disorders have an increased risk of colorectal carcinomas. These disorders include familial adenomatous polyposis, Peutz-Jeghers syndrome, and juvenile polyposis syndrome. Each disease has its own cutaneous signature that aids dermatologists in the early diagnosis and detection of hereditary GI malignancy. These disease processes are associated with particular gene mutations that can be used in screening and to guide additional genetic counseling. In addition, there is a group of hamartomatous syndromes, some of which are associated with phosphatase and tensin homolog (PTEN) gene mutations, which present with concurrent skin findings. These include Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, and Cronkhite-Canada syndrome. Finally, paraneoplastic disorders are another subcategory of GI diseases associated with cutaneous manifestations, including malignant acanthosis nigricans, Leser-Trélat sign, tylosis, Plummer-Vinson syndrome, necrolytic migratory erythema, perianal extramammary Paget disease, carcinoid syndrome, paraneoplastic dermatomyositis, and paraneoplastic pemphigus. Each of these disease processes have been shown to be associated with an increased risk of GI malignancy. This underscores the important role of dermatologists in the diagnosis, detection, monitoring, and treatment of these disorders while consulting and interacting with their GI colleagues.

    Diagnosis of leishmaniasis in immunosuppressed patients may be a serious challenge for physicians because of the major clinical and laboratory differences with immunocompetent patients. In immunosuppressed patients, the disease is characterized usually by disseminated visceral involvement, atypical cutaneous lesions and persistent negativity of diagnostic tests. Here, we report an eight-yr-old liver transplant recipient with concomitant cutaneous and visceral leishmaniasis in whom the cutaneous lesion led to the diagnosis of systemic involvement.

    Cutaneous wounds are among the most common soft tissue injuries. Wounds involving dermis suffer more from outside influence and higher risk of chronic inflammation. Therefore the appearance and function restoration has become an imperative in tissue engineering research. In this study, cell-aggregates constructed with green fluorescent protein-expressing (GFP+) rat bone marrow mesenchymal stem cells (BMMSCs) were applied to rat acute full-layer cutaneous wound model to confirm its pro-regeneration ability and compare its regenerative efficacy with the currently thriving subcutaneous and intravenous stem cell administration strategy, with a view to sensing the advantages, disadvantages and the mechanism behind. According to results, cell-aggregates cultured in vitro enjoyed higher expression of several pro-healing genes than adherent cultured cells. Animal experiments showed better vascularization along with more regular dermal collagen deposition for cell-aggregate transplanted models. Immunofluorescence staining on inflammatory cells indicated a shorter inflammatory phase for cell-aggregate group, which was backed up by further RT-PCR. The in situ immunofluorescence staining manifested a higher GFP+-cell engraftment for cell-aggregate transplanted models versus cell administered ones. Thus it is safe to say the BMMSCs aggregate could bring superior cutaneous regeneration for full layer cutaneous wound to BMMSCs administration, both intravenous and subcutaneous. PMID:26594024

    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.

    The purpose of this study was to investigate the participation of lipid peroxide (LP) in some skin damages due to ultraviolet (UV) irradiation. Results obtained were as follows. 1) Long wave UV (UVA) was irradiated to rat skin homogenates. The levels of LP increased linearly with irradiation time. 2) When 8-methoxypsoralen was added to the homogenates prior to UVA irradiation, however, the LP levels showed no increase. 3) Various anti-oxidative agents were added to homogenates and UVA was irradiated. Only Vit. E reduced the LP levels in proportion to its concentrations. 4) Anti-oxidative agents were given to rats which were then exposed to PUVA (8-methoxypsoralen plus UVA) treatment. Among them, administration of Vit. E and pantethine was associated with reduction of serum and cutaneous LP levels with only slight histologic changes in the involved skin. 5) Vit. E deficient rats were treated with PUVA. In these models, cutaneous LP levels raised from 24 hours to 96 hours after PUVA treatment and histologic changes such as vacuolization, blister formation and cell degeneration were remarkable. From the above data, it became evident that lipid peroxidation took place in skin tissue per se and even in the UVA wave length region. After PUVA treatment, cutaneous LP levels correlated relatively well with histologic changes of the involved skin. The results suggested that LP played a certain role in skin damages due to UV.

    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

    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.

    Cutaneous applications are gaining popularity in the treatment of cutaneous pain and of painful disorders in joints and muscle. The low pH-pain model in human skin has previously been able to demonstrate the effects of NSAIDs in dose-dependent manner and to establish time-effect relationships. We examined the analgesic action of ibuprofen after cutaneous application and compared the effects with oral administration. The two studies (with n = 12 subjects each) were performed in a double-blind, randomized fashion with a 1-week cross-over interval. In study 1 volunteers received intradermal infusions with phosphate buffered saline solution of pH 5.2 and received either 800 mg ibuprofen per os and topical placebo, or 4 g of a 5% commercial ibuprofen gel topically applied and oral placebo capsules, respectively. In study 2 the same protocol was applied with painful intramuscular infusion of stronger, isotonic phosphate buffer (pH 5.2). The flow rate of the pH-infusion was individually adjusted to induce pain with a magnitude of 20% on a visual analogue scale (ranging from 'no' (0%) to 'unbearable pain' (100%)). Ibuprofen (S-, R-) plasma levels after oral administrations were measured with HPLC, and after topical applications, by gas chromatography combined with mass spectroscopy to determine plasma levels in the range of ng/ml. In the cutaneous model pain ratings decreased to zero after topical verum gel within 45 min of the observation period of 55 min. Pain reduction after peroral ibuprofen was of the same magnitude, but was achieved within only 30 min. In the muscle model, the commercial ibuprofen gel did not reduce the pain in the acidic muscle. The peroral ibuprofen was less effective in the muscle compared to the skin pain model, although there was a significant progressive pain reduction within 55 min. Reasons for the differential susceptibility of cutaneous vs muscular acidosis pain to ibuprofen remain to be established. PMID:10957700

    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.

  7. Diagnosis and therapy of cutaneous radiation syndrome. Individual radiosensitivity assessment in patients undergoing medical exposures presenting severe cutaneous radiation induced lesions

    International Nuclear Information System (INIS)

    Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burn Center) is one of the reference hospitals of the Medical Radiological Emergency Response Network of Argentina. In the frame of an agreement between the Burn Center and the Nuclear Regulatory Authority of Argentina, a research project for an approach based on diagnosis and therapy of cutaneous radiation induced lesions is in progress. Individual radiosensitivity assessment was conducted in patients included in this research protocol that showed acute and/or late cutaneous reactions with grades 3 and 4 of the Toxicity criteria of the Radiation Therapy Oncology Group (RTOG) and the European organization for research and treatment of cancer (EORTC). DNA repair capacity and its kinetics were evaluated in human peripheral blood lymphocytes using alkaline comet assay and micronucleus test. In this paper, two representative cases, in which the research protocol was applied, are presented. Therapeutic response and its correlation with radiosensitivity test results are described. Case 1: female patient undergoing external radiotherapy for invasive ductal breast cancer that presented acute cutaneous radiotoxicity, grade 3 (confluent moist epithelitis, )that led to treatment break. Case 2: male patient undergoing coronary angioplasty (interventional radiology), which developed late cutaneous radiotoxicity, grade 4 (ulceration at the dorsal region). Patients were treated with: topic administration of trolamine and silver sulfadiazine with lidocaine, associated with systemic administration of pentoxiphiline and anti-oxidants. The therapeutic response was evaluated through clinical follow-up, serial photographic record and complementary tests (tele thermography and high frequency ultrasonography). Case 1 response was positive (favorable) with early local recovery and complete remission of signs and symptoms after 5 months. Both MN frequencies and comet assay showed values compatible with normal radiosensitivity

    Primary cutaneous lymphomas (PCLs) are a heterogeneous group of lymphoid tumors that originate primarily in the skin. Most PCLs (75%) are T-cell lymphomas and only 20% to 25% involve B cells. It is important to differentiate between cutaneous lymphomas and lymph node tumors given the differences in their molecular biology and clinical, histopathologic, and immunophenotypic features. Moreover, PCLs generally follow a more indolent course and require different treatments. Many treatment options are available for managing PLC's. The choice should be based primarily on the clinical stage of disease but must also take into consideration other factors, such as the patient's age and general health, the availability and accessibility of the treatment, and the cost-benefit ratio. It will be important to use a multidisciplinary approach, involving a team of expert dermatologists, hematologist-oncologists, and radiotherapists who are familiar with this rare disease. Recent years have seen the emergence of many new therapies, particularly for advanced stages of the disease and for patients whose tumors have proven refractory to treatment. The objective of this article is to review all the treatment options available to us. PMID:22575363

    Myeloid sarcoma, considered to herald the onset of a blast crisis in the setting of chronic myeloproliferative neoplasm/dysplasia, typically presents during the course of the disorder. Cutaneous involvement is uncommon and lesions on genital skin are seldom seen. We present a case of a well-differentiated myeloid sarcoma in the penile foreskin in an apparently healthy 29-year-old male presenting with phimosis. The unusual composition of the inflammatory cell infiltrate, and characteristic sparing of dermal blood vessels, nerves and smooth muscle fibres led to the correct diagnosis. Absence of commonly observed changes in the circumcision skin like those of balanitis xerotica was also helpful. Detailed hematological work up revealed a previously undiagnosed chronic myeloid leukemia in chronic phase. The patient also had simultaneous priapism, another rare presentation of chronic myeloid leukemia. One year hence, the patient is in hematological remission with no evidence of extramedullary disease. Although priapism has been described as a rare presenting symptom in chronic myeloid leukemia, the present case is unique as this is the first time a cutaneous myeloid sarcoma has been documented in the penile foreskin.

    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.

    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.

    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)

    Full Text Available BACKGROUND: Primary cutaneous melanoma still constitutes the main cause of skin cancer death in developed countries, and its incidence in recent years has been increasing in a steady, worrisome manner. OBJECTIVES: This study evaluated the clinical, epidemiological and demographic aspects of this disease, and correlated them with patient prognosis. METHODS: Using epidemiologic and clinical data, we analyzed 84 patients with mild to severe primary cutaneous melanoma treated between 1990 and 2007. Slides containing surgical specimens were analyzed, and new slides were made from archived paraffin sections when necessary. RESULTS: The melanoma incidence was higher in areas of sun exposure, with lesions commonly observed in the trunk for males, and lower limbs for females. In addition to Breslow's thickness and ulceration (p = 0.043 and p 1 mm and 4 mm and the mitotic index (0 when absent or 1 when >1 per mm² allowed the establishment of a prognostic score: if the sum was equal to or over three, nearly all (91.7% patients had systemic disease. The 5-year survival was approximately seventy percent. CONCLUSION: Because American Join Committee of Cancer Staging will update the classification of malignant tumors (TNM staging in the near future, and introduce mitosis as a prognostic factor, our results show the importance of such a feature. Additional studies are necessary to confirm the importance of a prognostic score as proposed herein.

    Full Text Available Background: Adverse cutaneous drug reactions (ACDRs are the most commonly reported adverse drug events. The causative drugs and clinical patterns of ACDRs are different in various populations. This study was conducted to identify the clinical patterns, causative drugs and reasons for drug administration in patients hospitalized due to ACDR. Materials and Methods: This retrospective study was carried out in a referral university hospital, Isfahan, Iran. The medical records of all patients who were hospitalized in the Dermatology Department due to ACDRs were reviewed covering an 8-year period between December 2006 and August 2013. Results: A total number of 282 patients with the mean age of 29.48 ± 21.18 years were hospitalized in this time period, of which 61% were females. The most common clinical patterns regarding the final diagnosis were Stevens-Johnson syndrome (SJS (32%, exanthematous drug eruptions (24.5% and toxic epidermal necrolysis (TEN (11%. Anticonvulsants were the most frequently implicated drug group (51.8% followed by antibiotics (33.7% and analgesics and non-steroidal anti-inflammatory drugs (5.7%. The most common cause of drug administration was seizure (30% and then upper respiratory tract infections (12%. The frequency distribution of clinical types of reactions was different between age groups (P < 0.001. The severe types (SJS, TEN, drug rash with eosinophilia and systemic symptoms and overlap syndrome were more frequent in the patients aged ≤50 years old (55.2% compare to those aged ≤50 years (28% (P = 0.001. Conclusion: The main causative drugs of ACDRs were anticonvulsants and antibiotics. However, the sever types of reactions were more prevalent.

  1. Muscle metaboreceptor modulation of cutaneous active vasodilation

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

    1998-01-01

    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 < 0.05), whereas there were no significant changes in CVC at the bretylium treated sites. The succeeding bout of isometric exercise in hyperthermia significantly reduced CVC at both untreated (pre-exercise: 59.0 +/- 4.8, exercise: 47.3 +/- 4.0, PEI: 50.1 +/- 4.1% of maximum; both P < 0.05) and bretylium treated sites (pre-exercise: 61.4 +/- 7.3, exercise: 50.6 +/- 5.1, PEI: 53.9 +/- 6.0% of maximum, both P < 0.05). At both sites, CVC during PEI was lower than during the pre-exercise period (P < 0.05). Sweat rate rose significantly during both bouts of isometric exercise and remained elevated during PEI. CONCLUSIONS: These data suggest that the reduction in CVC during isometric exercise in hyperthermia, including the inhibition of the active vasodilator system, is primarily mediated by muscle

    Del Rosso, James Q; Kircik, Leon H

    2013-11-01

    Superficial cutaneous fungal infections (SCFIs) are commonly encountered in clinical practice in the United States, and comprise infections of the skin by dermatophytes and yeasts. The most common organisms causing SCFI are dermatophytes, especially Trichophyton spp. With the exception of onchomycosis and tinea capitis, most cases of SCFIs are amenable to properly selected topical antifungal therapy used over an adequate period of time. A variety of topical antifungal agents are available for the treatment of SCFIs, and they encompass a few major chemical classes: the polyenes (ie, nystatin), imidazoles (ie, ketoconazole, econazole, oxiconazole, etc), allylamines (ie, naftifine, terbinafine), benzylamines (ie, butenafine), and hydroxypyridones (ie, ciclopirox). The 2 major classes that represent the majority of available topical antifungal agents are the azoles and the allylamines. Overall, the allylamines are superior to the azoles in activity against dermatophytes, although both are clinically effective. The reverse is true against yeasts such as Candida spp and Malassezia spp, although topical allylamines have proven to be efficacious in some cases of tinea versicolor and cutaneous candidiasis. Naftifine, a topical allylamine, is fungicidal in vitro against a wide spectrum of dermatophyte fungi and has been shown to be highly effective against a variety of cutaneous dermatophyte infections. Rapid onset of clinical activity and favorable data on sustained clearance of infection have been documented with naftifine. The more recent addition of naftifine 2% cream has expanded the armamentarium, with data supporting a clinically relevant therapeutic reservoir effect after completion of therapy. PMID:24196340

    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. Laser Doppler measurement of cutaneous blood flow

    International Nuclear Information System (INIS)

    Laser Doppler velocimetry is an instrument system which has only recently been applied to the evaluation and quantitation of perfusion in the micro-vascular bed. The instrument is based on the Doppler principle, but uses low power laser light rather than the more commonly used ultrasound, and has a sample volume of approximately 1 mm/sup 3/. As it is non-invasive, it can be used on any skin surface or exposed microvascular bed and provides a continuous semi-quantitative measure of microcirculatory perfusion, it has a number of advantages as compared to other cutaneous blood flow measurement techniques. Initial studies have shown that it is easily used, and it has demonstrated good correlation with both xenon radio-isotope clearance and microsphere deposition techniques. Areas of current evaluation and utilization are in most major areas of medicine and surgery and include plastic, vascular and orthopaedic surgery, dermatology, gastro-enterology, rheumatology, burns and anaesthesiology

    Sixteen patients - 12 with cutaneous T cell lymphoma (CTCL), 1 with Sézary syndrome, 1 with actinic reticuloid, and 2 with parapsoriasis variegata - were treated with either a new, potent arotinoid alone or with combined etretinate (Tigason) and PUVA therapy (Re-PUVA). 92% of all patients showed a minor up to a distinct response of their skin lesions within 12.6 +/- 7.4 weeks. More than 50% of the skin lesions cleared in 67% of the patients. After discontinuation of the retinoid therapy, relapses occurred in all cases within 3-10 weeks. There was no difference between the therapeutic efficacy of arotinoid alone and the Re-PUVA regimen, but the latter was less toxic. PMID:3500880

    2016-05-01

    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. PMID:26833684

    Alrajhi, A A

    2003-02-01

    Cutaneous Leishmaniasis is a vector-borne protozoal infection of the skin. Several species of Leishmania cause this disease in the Old World. It is manifested as chronic nodular to ulcerative lesions of the skin, which last for many months and may be disfiguring. They eventually heal leaving a scar. Local care of the lesion and treatment of secondary bacterial infection are essential for healing. Antileishmania therapy is indicated in immunocompromised hosts, patients with progressive, multiple, or critically located lesions. Pentavalent antimony compounds remain the main therapeutic option for all species. They are given intravenously (i.v.), intramuscularly (i.m.), or intralesionally. Cryotherapy, and some systemic antifungal agents have been used successfully. Oral azoles are promising new treatments for lesions caused by L. Major. Several other alternatives and their evidence are also presented. PMID:12728282

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.

    2016-01-01

    Ionizing radiation is an important treatment modality for a variety of malignant conditions. However, development of radiation-induced skin changes is a significant adverse effect of radiation therapy (RT). Cutaneous repercussions of RT vary considerably in severity, course, and prognosis. When they do occur, cutaneous changes to RT are commonly graded as acute, consequential-late, or chronic. Acute reactions can have severe sequelae that impact quality of life as well as cancer treatment. Th...

    Following a skin injury, the damaged tissue is repaired through the coordinated biological actions that constitute the cutaneous healing response. In mammals, repaired skin is not identical to intact uninjured skin, however, and this disparity may be caused by differences in the mechanisms that regulate postnatal cutaneous wound repair compared to embryonic skin development. Improving our understanding of the molecular pathways that are involved in these processes is essential to generate new...

    2012-08-01

    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.

    Cutaneous manifestations of parasitic infections often result in discomfort, debilitation, and even stigmatization. Data on cutaneous manifestations of parasitic infections, however, are limited. This article provides updates on the cutaneous manifestations of parasitic infections which are known to occur in Western Pacific and Southeast Asian regions, such as scabies, pediculosis, cutaneous larva migrans, larva currens, cutaneous schistosomiasis, cutaneous enterobiasis, cutaneous cysticercosis, acute dermatolymphangioadenitis (lymphatic filariasis), and cutaneous amoebiasis. The lack of epidemiological data on these conditions suggests the need for improvements in recording and reporting of cases. Utilization of advance diagnostic modalities and capacity building of health workers are important for proper case management. Cutaneous manifestations of parasitic infections are a topic rarely studied and thus represent an opportunity for further research. PMID:27447892

  5. Topical menthol increases cutaneous blood flow.

    Science.gov (United States)

    Craighead, Daniel H; Alexander, Lacy M

    2016-09-01

    Menthol, the active ingredient in several topically applied analgesics, activates transient receptor potential melastatin 8 (TRPM8) receptors on sensory nerves and on the vasculature inducing a cooling sensation on the skin. Ilex paraguariensis is also a common ingredient in topical analgesics that has potential vasoactive properties and may alter the mechanisms of action of menthol. We sought to characterize the microvascular effects of topical menthol and ilex application and to determine the mechanism(s) through which these compounds may independently and combined alter cutaneous blood flow. We hypothesized that menthol would induce vasoconstriction and that ilex would not alter skin blood flow (SkBF). Three separate protocols were conducted to examine menthol and ilex-mediated changes in SkBF. In protocol 1, placebo, 4% menthol, 0.7% ilex, and combination menthol+ilex gels were applied separately to the skin and red cell flux was continuously measured utilizing laser speckle contrast imaging (LSCI). In protocol 2, seven concentrations of menthol gel (0.04%, 0.4%, 1%, 2%, 4%, 7%, 8%) were applied to the skin to model the dose-response curve. In protocol 3, placebo, menthol, ilex, and menthol+ilex gels were applied to skin under local thermal control (34°C) both with and without sensory nerve blockage (topical lidocaine 4%). Post-occlusive reactive hyperemia (PORH) and local heating (42°C) protocols were conducted to determine the relative contribution of endothelium derived hyperpolarizing factors (EDHFs)/sensory nerves and nitric oxide (NO), respectively. Red cell flux was normalized to mean arterial pressure expressed as cutaneous vascular conductance (CVC: flux·mmHg(-1)) in all protocols. Topical menthol application increased SkBF compared to placebo (3.41±0.33 vs 1.1±0.19CVC: peffect, p<0.05) with an ED50 of 1.0%. Similarly, SkBF was increased after menthol application during PORH (3.62±0.29 vs. 2.50±0.21flux·mmHg(-1); p<0.001), but not local heating

    Efficient topical drug administration for the treatment of superficial fungal infections would deliver the therapeutic agent to the target compartment and reduce the risk of systemic side effects. However, the physicochemical properties of the commonly used azole antifungals make their formulation a considerable challenge. The objective of the present investigation was to develop aqueous micelle solutions of clotrimazole (CLZ), econazole nitrate (ECZ) and fluconazole (FLZ) using novel amphiphilic methoxy-poly(ethylene glycol)-hexyl substituted polylactide (MPEG-hexPLA) block copolymers. The CLZ, ECZ and FLZ formulations were characterized with respect to drug loading and micelle size. The optimal drug formulation was selected for skin transport studies that were performed using full thickness porcine and human skin. Penetration pathways and micellar distribution in the skin were visualized using fluorescein loaded micelles and confocal laser scanning microscopy. The hydrodynamic diameters of the azole loaded micelles were between 70 and 165nm and the corresponding number weighted diameters (d(n)) were 30 to 40nm. Somewhat surprisingly, the lowest loading efficiency (13-fold higher than that from Pevaryl® cream (22.8±3.8 and 1.7±0.6μg/cm(2), respectively). A significant enhancement was also observed with human skin; the amounts of ECZ deposited were 11.3±1.6 and 1.5±0.4μg/cm(2), respectively (i.e., a 7.5-fold improvement in delivery). Confocal laser scanning microscopy images supported the hypothesis that the higher delivery observed in porcine skin was due to a larger contribution of the follicular penetration pathway. In conclusion, the significant increase in ECZ skin deposition achieved using the MPEG-dihexPLA micelles demonstrates their ability to improve cutaneous drug bioavailability; this may translate into improved clinical efficacy in vivo. Moreover, these micelle systems may also enable targeting of the hair follicle and this will be investigated

    Thalidomide is effective for treating severe cutaneous lupus patients. The aim of this study was to observe the optimum effective and maintenance doses of thalidomide to maximize clinical benefit and minimize side effects for patients with cutaneous lupus in China. Sixty-nine patients with lupus rash from eight hospitals in China were enrolled and treated with different doses of thalidomide. We started the dose of thalidomide at 25 mg daily and gradually increased administration dose once a week until erythema was markedly improved. The effective and maintenance doses were documented. The size of skin lesions was noted once a week. Systemic lupus erythematosus disease activity index (SLEDAI) score, levels of erythrocyte sedimentation rate (ESR), and serum TNF-α were measured before and after treatment. The remission rates were evaluated weekly until 8 weeks. Sixty-eight percent of patients showed an effective dose of 50 mg daily; another 13, 10, and 9 % of patients had an effective dose of 100, 75, and 25 mg daily, respectively. The maintenance dose was 50 mg daily for 71 % of the patients, and 100, 75, and 25 mg daily for 9, 14, and 6 % of the patients. SLEDAI score and serum ESR levels significantly decreased 4 weeks after thalidomide treatment. At the end of the fourth week, the rates of complete remission, partial remission, and no response were 56 % (n = 39), 41 % (n = 28), and 3 % (n = 2). At the eighth week, the rate of total remission rose up to 100 %. The most common side effects were drowsiness and constipation. No peripheral neuropathy was observed in these patients. Thalidomide at a dose of 50 mg daily may offer a better benefit to risk ratio in the treatment of Chinese cutaneous lupus patients. PMID:27097914

    Calcific uremic arteriolopathy (calciphylaxis) is an uncommon complication of chronic renal failure that is associated with high morbidity and mortality. We report 16 patients (13 female) who presented between 1985 and 1996. All patients developed painful livido reticularis that progressed to cutaneous necrosis and ulceration (11 cases on the proximal extremities and five cases on the distal extremities). Two patients with predominately distal leg disease survived; the cause of death in the other 14 patients was sepsis (six patients), withdrawal from dialysis (three), cardiac arrest (three), and gastrointestinal hemorrhage (two). Mesenteric ischemia from intestinal vascular calcification occurred in two cases. Clinical factors identified included the use of warfarin therapy in seven cases and significant weight loss (>10% body weight) in seven cases in the 6 months preceding the development of calcific uremic arteriolopathy. Skin pathology was studied in 12 cases, with all showing calcific panniculitis and small vessel calcification. Electron microscopic spectral analysis of the mineral content of the calcific lesions in the subcutaneous tissue showed only calcium and phosphorous. In two cases, substitution of low molecular weight heparin for warfarin therapy resulted in clinical improvement. Current theories of pathogenesis and treatment are reviewed. This study confirms the high morbidity and mortality of calcific uremic arteriolopathy producing ischemic tissue necrosis while drawing attention to significant weight loss and warfarin therapy as risk factors for the development of ischemic tissue necrosis. Hyperbaric oxygen therapy warrants further study. PMID:9740153

  12. Cutaneous neoplasia following PUVA therapy for psoriasis

    International Nuclear Information System (INIS)

    To determine the risk of cutaneous neoplasia following photochemotherapy (PUVA), we reviewed patients with psoriasis treated at out unit between 1979 and 1991. Two hundred and forty-five patients were assessed, with a median duration of follow-up of 9.5 years. Fifty-nine per cent were male, and 41% female. The median number of exposures was 59, and the median total dose was 133J/cm2 for the group as a whole. Non-melanoma skin cancers (NMSC) occurred in six individuals (2.4%), basal cell carcinoma occurred in all six and one individual also developed four squamous cell carcinomas and Bowen's disease of the penis. No cases of malignant melanoma were recorded. Patients who developed NMSC received a median number of 225 exposures and a median cumulative dose of 654J/cm2. Compared with a control study population in West Glamorgan, Wales, there was a 1.4 (95% confidence limits (CL) 0.5 and 3.1) times increased risk of NMSC. A statistically significant increased incidence of NMSC was found for patients who had received 100 or more exposures, and 250 or more J/cm2, with risks of 3.7 (95% CL 1.0 and 9.5), and 4.0 (95% CL 1.1 and 10), respectively. A PUVA dose of 2 or < 100 exposures conferred a minimal increase in risk of NMSC in our study population. (author)

  13. Cutaneous cylindroma: it's all about MYB.

    Science.gov (United States)

    Corda, Gabriele; Sala, Arturo

    2016-08-01

    Cutaneous cylindroma is a rare benign tumour that occasionally turns into malignant cylindrocarcinoma. The cancer can be sporadic or emerge in the context of Brooke-Spiegler syndrome (BSS), an inheritable condition characterized by mutation of the gene CYLD, encoding a tumour suppressor protein that controls the activity of the transcription factor NF-kB. Sporadic cylindromas present histological features shared with adenoid cystic carcinoma (ACC), a head and neck cancer originating from salivary or other exocrine glands. Like ACCs, sporadic cylindromas express, although at lower frequency, the aberrant fusion transcript MYB-NFIB. In a paper recently published in the Journal of Pathology, the research teams led by Neil Rajan and Goran Stenman demonstrate that CYLD-defective cyclindromas in BSS patients are negative for the MYB-NFIB fusion. Only the wild-type MYB oncoprotein is activated in the majority of these tumours. RNA interference studies in cells derived from BSS patients indicate that ablating MYB expression results in a striking reduction of cylindroma cell proliferation, suggesting that MYB plays a pivotal role in the biology of this cancer. The take-home message of the study is that activation of MYB, in its wild-type form or fusion derivatives, is a common feature of spontaneous and hereditary cylindromas, constituting a potentially actionable therapeutic target.

    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.

    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.

    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.

  17. Worldwide Increasing Incidences of Cutaneous Malignant Melanoma

    Full Text Available The incidence of cutaneous malignant melanoma (CMM has been increasing at a steady rate in fair-skinned populations around the world for decades. Scientists are not certain why CMM has been steadily increasing, but strong, intermittent UVB (290–320 nm exposures, especially sunburn episodes, probably initiate, CMM, while UVA (321–400 nm passing through glass windows in offices and cars probably promotes it. The CMM incidence may be increasing at an exponential rate around the world, but it definitely decreases with increasing latitude up to ~50°N where it reverses and increases with the increasing latitude. The inversion in the incidence of CMM may occur because there is more UVA relative to UVB for most of the year at higher latitudes. If windows, allowing UVA to enter our indoor-working environment and cars, are at least partly responsible for the increasing incidence of CMM, then UV filters can be applied to reduce the rate of increase worldwide.

  18. Control of the Cutaneous Circulation by the Central Nervous System.

    2016-01-01

    The central nervous system (CNS), via its control of sympathetic outflow, regulates blood flow to the acral cutaneous beds (containing arteriovenous anastomoses) as part of the homeostatic thermoregulatory process, as part of the febrile response, and as part of cognitive-emotional processes associated with purposeful interactions with the external environment, including those initiated by salient or threatening events (we go pale with fright). Inputs to the CNS for the thermoregulatory process include cutaneous sensory neurons, and neurons in the preoptic area sensitive to the temperature of the blood in the internal carotid artery. Inputs for cognitive-emotional control from the exteroceptive sense organs (touch, vision, sound, smell, etc.) are integrated in forebrain centers including the amygdala. Psychoactive drugs have major effects on the acral cutaneous circulation. Interoceptors, chemoreceptors more than baroreceptors, also influence cutaneous sympathetic outflow. A major advance has been the discovery of a lower brainstem control center in the rostral medullary raphé, regulating outflow to both brown adipose tissue (BAT) and to the acral cutaneous beds. Neurons in the medullary raphé, via their descending axonal projections, increase the discharge of spinal sympathetic preganglionic neurons controlling the cutaneous vasculature, utilizing glutamate, and serotonin as neurotransmitters. Present evidence suggests that both thermoregulatory and cognitive-emotional control of the cutaneous beds from preoptic, hypothalamic, and forebrain centers is channeled via the medullary raphé. Future studies will no doubt further unravel the details of neurotransmitter pathways connecting these rostral control centers with the medullary raphé, and those operative within the raphé itself. © 2016 American Physiological Society.

  19. Dissociation of cutaneous vascular permeability and the development of cutaneous late-phase allergic reactions

    International Nuclear Information System (INIS)

    Cutaneous late-phase allergic reactions (LPR) are characterized by an early, immediate hypersensitivity whealing reaction followed by persistent, localized induration that peaks 6 to 8 hours later. In this study we used rodents to examine the relationship between vascular permeability (VP) and induration during LPR. Efflux of macromolecular tracers from the vasculature into skin was measured with the use of radiolabeled albumin and neutral dextran tracers having large molecular radii. To induce LPR immunologically, we used either intradermal injections of antirat IgE or passive cutaneous sensitization with IgE antidinitrophenyl followed 24 hours later by intravenous injection of albumin-dinitrophenyl. [125I]albumin and [3H]dextran tracers were injected intravenously before and at various intervals after the induction of LPR. Although a marked increase in VP occurred within the first 30 minutes after induction of mast cell degranulation, analysis of radiolabeled tracer accumulation at 2, 4, 8, and 24 hours failed to demonstrate any further increase in VP. These findings indicate that the induration observed in rodent LPR is not associated with increased VP beyond the immediate hypersensitivity stage and suggest that impairment of lymphatic drainage, cellular infiltration, and/or fibrin deposition are contributing factors

    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.

    Chromoblastomycosis is a rare chronic fungal infection of skin and subcutaneous tissue. It is primarily a disease of tropical and subtropical regions and affects mainly the agricultural workers following trauma with vegetable matter. Cutaneous Chromoblastomycosis may clinically mimic cutaneous tuberculosis as both the condition usually presents with hyper pigmented verrucous lesion of skin. Here in we report a case of chronic cutaneous Chromoblastomycosis in a middle aged woman from north eastern part of India, who was initially misdiagnosed as Tuberculosis verrucosa cutis. In histopathology characteristic brown colored spores of the fungus (also known as copper pennies) were seen within dermal abscess. The organism isolated from culture of the biopsy material was Fonsecaea pedrosoi thus confirming our diagnosis of cutaneous chromoblastomycosis. The patient responded well to oral Itraconazole. The dermatologists and pathologists should be aware of this condition especially when dealing with verrucous lesion of the skin. The pathologists should search for fungal spores in cutaneous lesion with pseudoepitheliomatous hyperplasia and dermal abscess. PMID:24272932

    Leishmaniasis is a disease with worldwide increasing incidence, which in Germany is almost exclusively observed in patients who have travelled to classical endemic regions such as the Mediterranean basin. Cause of the disease is an infection with protozoan parasites of the genus Leishmania, which are transmitted by sand flies and replicate intracellularly within mammalian hosts. Depending on the inoculated parasite (sub-) species and the immune status of the host, a local cutaneous, diffuse cutaneous, mucocutaneous or visceral form of leishmaniasis will develop. Cutaneous leishmaniasis, which frequently appears only weeks after the bite of a sand fly, starts with the formation of a papule, which subsequently can turn into a skin ulcer. The latter may heal spontaneously after months leaving behind a scar or persist as chronic, non-healing cutaneous leishmaniasis. If cutaneous leishmaniasis is suspected, a sterile skin biopsy followed by appropriate diagnostic measures in a specialized laboratory to identify the pathogen should be performed. For the decision on the type of therapy, several clinical parameters (e.g. number and localization of lesions, immune status) and, most importantly, the underlying parasite (sub-) species need to be considered. Therapy can consist of a variety of topical measures or systemic drug treatment. A modern and safe vaccine does not yet exist. PMID:22422121

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

    Directory of Open Access Journals (Sweden)

    2014-07-01

    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.

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

    2010-06-01

    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.

    Introduction. Angiosarcoma is a rare cancer of the inner lining of blood vessels and can arise anywhere in the body, most commonly presenting as cutaneous disease in elderly patient, involving head and neck (H&N), especially the scalp. Pegylated liposomal doxorubicin (PLD) is one of the available treatments in patients with advanced or metastatic disease. Common toxicities are myelosuppression, palmar-plantar erythrodysesthesia, nausea, and stomatitis. Regarding PLD-related pulmonary fibrosis in an uncommon toxicity, there are few cases reported in literature. None of these occurred in angiosarcoma. Methods. This is a case report describing an elderly patient treated with PLD for advanced H&N cutaneous angiosarcoma who developed G5 pulmonary toxicity after the second PLD administration. Results. According to our data and patient clinical outcome, we believe that she passed away from fatal PLD-induced pulmonary fibrosis. This is the first case of fatal interstitial pneumonitis in a 77-year-old woman treated with PLD for angiosarcoma. The case has been reported for its rarity. Conclusions. Pathophysiology of this phenomenon is still unclear and more studies are necessary to understand the true incidence of pulmonary toxicities in patients in treatments with PLD and its mechanism.

    2016-01-01

    Acaricidal (tick) and insecticidal (flea) efficacy of systemically and cutaneously distributed ectoparasiticide products for dogs are compared based on permethrin and fluralaner as representative molecules. Results of efficacy studies against fleas and ticks are reviewed that show generally good to excellent results. Both externally and systemically distributed treatments have benefits and weaknesses in potentially preventing pathogen transmission by these arthropod vectors.Four general properties are considered related to the goal of providing optimal reduction in the risk of vector-borne pathogen transmission. These are: 1. Owner adherence to the recommended treatment protocol; 2. Rapid onset of activity following administration; 3. Uniform efficacy over all areas of the treated dog at risk for parasite attachment; 4. Maintenance of high efficacy throughout the retreatment interval. In considering these four factors, a systemically distributed acaricide can offer an option that is at least as effective as a cutaneously administered acaricide with regard to the overall goal of reducing the risk of vector-borne pathogen transmission.

    2016-01-01

    There have been exhaustive efforts to develop an efficient vaccine against leishmaniasis. Factors like host and parasite genetic characteristics, virulence, epidemiological scenarios, and, mainly, diverse immune responses triggered by Leishmania species make the achievement of this aim a complex task. It is already clear that the induction of a Th1, pro-inflammatory response, is important in the protection against Leishmania infection. However, many questions must still be answered to fully understand Leishmania immunopathology, especially regarding Leishmania-specific Th1 response induction, regulation, and persistence. A large number of Leishmania antigens able to induce pro-inflammatory response have been selected so far, but none of them demonstrated efficiency in protection assays. A possible explanation is that CD4 T cells display marked heterogeneity at a single-cell level especially regarding the production of Th1-defining cytokines and multifunctionality. It has been established in the literature that Th1 cells undergo a differentiation process, which can generate cells with diverse phenotypes and survival capabilities. Despite that, only a few studies evaluate this heterogenic response and the amount of multifunctional CD4 T cells induced by Leishmania vaccine candidates, missing what can be a crucial point in defining a correlate of protection after vaccination. Moreover, most of the knowledge involving the development of cutaneous leishmaniasis (CL) vaccines comes from the mouse model of infection with Leishmania major, which cannot be fully applied to New World Leishmaniasis. For this reason, the immune response triggered by infection with New World Leishmania species, as well as vaccine candidates, need further studies. In this review, we will reinforce the importance of evaluating the quality of immune response against Leishmania, using a multiparametric analysis in order to understand better this complex host-parasite interaction, discussing the

    Tuberculosis is one of the oldest diseases known to humankind and it is currently a worldwide threat with 8-9 million new active disease being reported every year. Among patients with co-infection of the human immunodeficiency virus (HIV), tuberculosis is ultimately responsible for the most deaths. Cutaneous tuberculosis (CTB) is uncommon, comprising 1-1.5% of all extra-pulmonary tuberculosis manifestations, which manifests only in 8.4-13.7% of all tuberculosis cases. A more accurate classification of CTB includes inoculation tuberculosis, tuberculosis from an endogenous source and haematogenous tuberculosis. There is furthermore a definite distinction between true CTB caused by Mycobacterium tuberculosis and CTB caused by atypical mycobacterium species. The lesions caused by mycobacterium species vary from small papules (e.g. primary inoculation tuberculosis) and warty lesions (e.g. tuberculosis verrucosa cutis) to massive ulcers (e.g. Buruli ulcer) and plaques (e.g. lupus vulgaris) that can be highly deformative. Treatment options for CTB are currently limited to conventional oral therapy and occasional surgical intervention in cases that require it. True CTB is treated with a combination of rifampicin, ethambutol, pyrazinamide, isoniazid and streptomycin that is tailored to individual needs. Atypical mycobacterium infections are mostly resistant to anti-tuberculous drugs and only respond to certain antibiotics. As in the case of pulmonary TB, various and relatively wide-ranging treatment regimens are available, although patient compliance is poor. The development of multi-drug and extremely drug-resistant strains has also threatened treatment outcomes. To date, no topical therapy for CTB has been identified and although conventional therapy has mostly shown positive results, there is a lack of other treatment regimens. PMID:26616847

    2016-01-01

    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.

    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

    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. PMID:26748858

    Secondary syphilis has been known since the late 19th century as the great imitator; however, some experts now regard cutaneous lymphoma as the great imitator of skin disease. Either disease, at times an equally fastidious diagnosis, has reported to mimic each other even.

    Full Text Available Secondary syphilis has been known since the late 19th century as the great imitator; however, some experts now regard cutaneous lymphoma as the great imitator of skin disease. Either disease, at times an equally fastidious diagnosis, has reported to even mimic each other. It is thus vital to consider these possibilities when presented with a patient demonstrating peculiar skin lesions. No other manifestation of secondary syphilis may pose such quandary as a rare case of rupioid syphilis impersonating cutaneous lymphoma. We present such a case, of a 36-year-old HIV positive male, misdiagnosed with aggressive cutaneous lymphoma, actually exhibiting rupioid syphilis thought secondary to immune reconstitution inflammatory syndrome (IRIS.

    Mucoepidermoid carcinoma (MEC) of the skin is an extremely rare neoplasm but is common in the major and minor salivary glands accounting of approximately 30% of all malignant tumors arising from these glands. Cutaneous involvement should be carefully assessed to exclude the possibility of metastases from distant sites. We report an 81 year-old man presenting a primary cutaneous mucoepidermoid carcinoma infiltrating his left parotid gland. Excision of the affected skin and a total parotidectomy with supraomohyoid neck dissection (level I-III) was performed followed by radiotherapy. No relapse after 2 years follow up has been observed. Since the primary cutaneous mucoepidermoid carcinoma is an aggressive neoplasm that frequently develops metastases it is important to distinguish it from primary MEC originating from the salivary glands for better management and suitable therapeutic decisions.

    Most cutaneous malignancies of the head and neck (HN) are non-melanoma skin cancers, predominantly basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs). Less common entities include Merkel cell carcinoma (MCC), sebaceous carcinoma (SC), and angiosarcoma. Treatment is based on histology subtype, stage, and extent of involvement. Surgery is the primary means of treatment and includes wide local excision, Mohs micrographic surgery, sentinel lymph node biopsy, and cervical lymphadenectomy. Multidisciplinary management including radiation and targeted chemotherapy are critical adjuncts to surgery. Surgical planning must balance oncologic, functional, and cosmetic considerations. This review addresses cutaneous manifestations of primary malignancies of the HN and dermatologic complications of small molecule inhibitors used for targeted therapy. A working knowledge of both the cutaneous malignancies (CM) in the head and neck as well as the secondary dermatologic manifestations is relevant to multiple disciplines including dermatology, medical oncology, radiation oncology, and surgical oncology.

    Koebner isomorphic response describes the phenomenon of histopathologically identical skin lesions of a preceding cutaneous disease appearing in sites of trauma. Wolf isotopic response describes the phenomenon of a new skin disease appearing in the site of an unrelated cutaneous disease. Neither of the phenomena has been reported in relation to systemic lupus erythematosus. This report describes a 17-year-old girl with systemic lupus erythematosus exhibiting particularly severe cutaneous involvement confined primarily to sun-exposed areas presenting with a dermatomal band of atrophic, scaling, erythematous papules, and plaques on her left shoulder extending down her left arm after herpes zoster eruption. The histopathologil result showed lupus erythematosus. This phenomenon is best considered as a Koebner isomorphic response, although Wolf isotopic response has some clinical relevance as well. Koebner isomorphic and Wolf isotopic responses are discussed as related to this case. PMID:22639953

    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.

    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.

    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.

    Full Text Available Abstract Langerhans cell sarcoma (LCS typically presents as cytologic atypia and clinical aggressiveness and may involve multiple organs during the progression of the disease. Primary skin LCS without any extra-cutaneous site association is extremely rare and only a few such cases have been described in the literature. We present a case of unusual primary LCS in skin occurring in a middle-aged male patient. Physical examination revealed a large ulcerated cutaneous lesion and a smaller nodular lesion were located in the skin of the extensor side of his right knee. There was no regional lymph node or any other extra-cutaneous organ involvement. Histologically, typical large and pleomorphological tumor cells with epithelioid appearance and significantly malignant cytological features were observed to infiltrate in dermis and subcutaneous tissue. By immunohistochemistry, the tumor cells were positive for CD1a, S-100 protein and largerin strongly and diffusely. However, these cells were negative for CD3, CD20, CD21, pan-cytokeratin, HMB-45, Melan-A, and MPO. A diagnosis of primary cutaneous LCS was made. The patient received systemic chemotherapy of CHOP regimen, and was on a regular follow-up period for 12 months. There was no sign of relapse of tumor or any other extra-cutaneous organ involvement by whole body positron emission tomography/computed tomography (PET/CT study. Because LCS is a high-grade malignancy with poor prognosis, it suggests that strict histological analysis and thorough radiographic examination are necessary for accurately diagnosing this tumor even if cutaneous involvement presented only.

    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

    Full Text Available Cutaneous vasculitis can be classified as primary or idiopathic; or secondary, when it presents as a manifestation of connective tissue diseases, infections, drug reactions or malignancies. Although most of the idiopathic cases are self-limited and responsive to supportive measures and nonsteroidal anti-inflammatory drugs, potent immunosuppressants are sometimes required for the management of the refractory situations. Here we describe a case of a 32-year-old Caucasian female patient with history of idiopathic cutaneous deep vasculitis unresponsive to methotrexate, dapsone, and cyclophosphamide who was effectively treated with infliximab.

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

    Directory of Open Access Journals (Sweden)

    2012-01-01

    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.

    A 3.5-year-old, castrated male, giant schnauzer was presented with alopecic pustular dermatitis. Immune-mediated hemolytic anemia had been diagnosed 45 days previously. At the time of presentation, the dog was receiving prednisone, azathioprine, and cyclosporine. Cutaneous protozoosis was diagnosed, and postmortem examination revealed protozoa within cutaneous, cardiac, pancreatic, and pulmonary tissues. The protozoa divided by endodyogeny, had the morphology of Toxoplasma gondii (T. gondii) tachyzoites, and stained positively with T. gondii polyclonal antibodies but not with antibodies to Neospora caninum or Sarcocystis neurona. Immunosuppression may have predisposed this dog to disseminated toxoplasmosis. PMID:15870255

    A 4-year-old, intact male rottweiler was presented with a 10-day history of papulonodular dermatitis. At the time of presentation, the dog was receiving prednisone and azathioprine to treat pemphigus foliaceus. Cutaneous neosporosis was diagnosed by immunohistochemistry on skin biopsy specimens and a high serum antibody titer to Neospora caninum by Neospora agglutination test. Electron microscopy examination of skin specimens further supported the diagnosis. Clindamycin therapy, together with withdrawal of immunosuppressive medication, resulted in prolonged clinical remission. This report documents cutaneous neosporosis in an adult dog and suggests that immunosuppressive therapy might be a predisposing factor. PMID:12220024

    Cutaneous dipththeria is an infectious bacterial disease endemic in tropical regions, but rarely diagnosed in Germany. Following travel in Sri Lanka, a 60-year-old German presented to our dermatological clinic with a skin ulcer and extensive erythematous erosive edema of his left foot. Corynebacterium diphtheriae was isolated from a swab of the lesion. There were no clinical signs of toxic diphtheria. The patient was treated with penicillin G and erythromycin, followed by a slow healing of the lesion. The isolated strain could be identified as toxigenic C. diphtheriae mitis. Due to increased travel activity, dermatologists should have uncommon infections like cutaneous diphtheria in mind. PMID:26525966

  9. The cutaneous radiation syndrome. A disorder of the cutaneous communication network?

    International Nuclear Information System (INIS)

    The effects of ionizing radiation, both wanted and unwanted, on regenerating tissues such as skin have traditionally exclusively been attributed to anti-proliferative activity on presumptive stem cells. The detailed mechanisms leading to clinical effects such as early erythema or late fibrosis remained largely unrevealed. In recent years this concept has been modified considerably, based on information primarily obtained by application of immunological and molecular biological methods. Concomitantly, our understanding of the skin organ as a complicated, both initiator and effector organ of the systemic immune response has enlarged dramatically, demonstrating a complex cutaneous intra- and intercellular communication network including pro- and anti-inflammatory cytokines and their receptors, adhesion molecules and surface antigens. These components regulate among others the interaction between epidermal and dermal cells, as well as microvascular endothelial cells, the latter representing the interface between the circulating immunocompetent cells (granulocytes, lymphocytes, etc) and the skin. Increasing evidence has been obtained that ionizing radiation modulates this network in a refined manner, involving transcriptional activation of immediate early (TNF-α, IL-1, -5, -6, -8, ICAM-1) as well as late (EGF-R, TGF-β responding genes. Though resembling other inflammatory conditions of the skin, a specific time and dose-dependant pattern after radiation exposure evolves, allowing a distinct discrimination between the effects of high and low single doses as well as fraction. This enlarged concept of the cutaneous radiation reaction offers new options for causal-oriented treatment with biological response modifiers including steroids and other immuno-suppressants as well as cytokines and receptor antagonists, as well as definition of optimal time windows for initiation and termination of therapeutic intervention.

    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

    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.

    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. PMID:27007563

    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...

  15. Serum from CBA/Ca mice vaccinated with irradiated cercariae of Schistosoma mansoni protects naive recipients through the recruitment of cutaneous effector cells

    International Nuclear Information System (INIS)

    Passive transfer experiments showed that 76% of the resistance induced in CBA/Ca mice by exposure to radiation-attenuated cercariae of Schistosoma mansoni could be transferred to naive recipients by administration of donor serum. The serum was twice as effective when given to the recipients at the time of cercarial challenge as compared to administration 5 days after challenge, a result which indicates that serum-dependent challenge elimination is probably accomplished in the cutaneous tissues. This view was confirmed by the observation that passive protection could be ablated by administration of a monoclonal antibody which depletes the cutaneous inflammatory reaction to cercarial penetration. Histopathological studies revealed that vaccine serum induced subdermal inflammatory reactions in challenged recipient mice which were identical both in duration and kinetics to those seen in conventionally vaccinated individuals. Challenge larvae, which had transformed from skin-stage to lung-stage parasites, became trapped within such reactions and eventually showed generalized vacuolation consistent with the onset of damage. Some foci were seen to contain degenerated leucocytes, free eosinophil granules and debris which is thought to represent the remnants of dead parasites. These data show that serum-transferred resistance in the vaccinated CBA/Ca mouse model involves the induction of a cutaneous inflammatory response in the recipients. (author)

    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.

    Ionizing radiation is an important treatment modality for a variety of malignant conditions. However, development of radiation-induced skin changes is a significant adverse effect of radiation therapy (RT). Cutaneous repercussions of RT vary considerably in severity, course, and prognosis. When they do occur, cutaneous changes to RT are commonly graded as acute, consequential-late, or chronic. Acute reactions can have severe sequelae that impact quality of life as well as cancer treatment. Thus, dermatologists should be informed about these adverse reactions, know how to assess their severity and be able to determine course of management. The majority of measures currently available to prevent these acute reactions are proper skin hygiene and topical steroids, which limit the severity and decrease symptoms. Once acute cutaneous reactions develop, they are treated according to their severity. Treatments are similar to those used in prevention, but incorporate wound care management that maintains a moist environment to hasten recovery. Chronic changes are a unique subset of adverse reactions to RT that may develop months to years following treatment. Chronic radiation dermatitis is often permanent, progressive, and potentially irreversible with substantial impact on quality of life. Here, we also review the etiology, clinical manifestations, pathogenesis, prevention, and management of late-stage cutaneous reactions to radiotherapy, including chronic radiation dermatitis and radiation-induced fibrosis.

  3. Assessment of cutaneous radiation fibrosis by 20 MHz-sonography

    International Nuclear Information System (INIS)

    Radiation fibrosis is the cardinal symptom of the chronicle stage of the cutaneous radiation syndrome. The degree of cutaneous fibrosis can clinically be estimated by palpation. High-frequency 20 MHz-sonography is an established, noninvasive procedure, which renders an exact determination of skin thickness and additionally densitometry is possible. We investigated 15 survivors of the Chernobyl accident in 1986, who developed symptoms of the chronic stage of the cutaneous radiation syndrome. We determined skin thickness and echogenicity of skin areas clinically suggestive of radiation fibrosis before, during and after treatment. 20 MHz-sonography showed a distinct enlargement of the echorich corium and a reduction of the subcutaneous fatty tissue in comparison with the unaffected, contralateral skin, here demonstrating typical features of radiation fibrosis, namely dermal fibrosis and reactive pseudoatrophy and fatty tissue. The histology presented an increase and swelling of the collagen fibers and atypical fibroblastic cells. The patients received treatment with low-dose interferon y (PolyfcronR, 3 x 50μg s.C., three times per week) up to 30 months. A marked reduction of skin thickness and echogenicity reaching nearly normal values could be observed. We conclude that 20 MHz-sonography is an easy to apply, noninvasive, well established procedure to quantify cutaneous radiation fibrosis and to assess therapeutic outcome

    Full Text Available Abstract Background Sarcoidosis is a multisystem disease of unknown origin characterized by the formation of noncaseating granulomas, in particular in the lungs, lymph nodes, eyes, and skin. Systemic treatment for cutaneous sarcoidosis can be used for large disfiguring lesions, generalized involvement, or recalcitrant lesions that did not respond to topical therapy. Case presentations We report three patients with recalcitrant cutaneous sarcoidosis who were treated with oral fumaric acid esters (FAE. Three female patients presented with cutaneous sarcoidosis that have proved to be refractory to various therapies, including corticosteroids and chloroquine. We treated the patients with FAE in tablet form using two formulations differing in strength (Fumaderm® initial, Fumaderm®. Dosage of FAE was performed according to the standard therapy regimen for psoriasis patients. After treatment with FAE (4–12 months, a complete clearance of skin lesions was achieved in the three patients. The side effects observed in this trial correspond to the well-known spectrum of adverse effects of FAE (flush, minor gastrointestinal complaints, lymphopenia. Conclusions On the basis of our findings FAE therapy seems to be a safe and effective regimen for patients with recalcitrant cutaneous sarcoidosis. Nevertheless further investigations are necessary to confirm our preliminary results.

    The aim of study was to describe clinico histopathological manifestations of cutaneous and gastric habronemiasis in horse. The adult worms live on the wall of the stomach and cutaneous of the host without internal migration. A 5 year old 700 kg warm-blood, cross gelding was referred to the Tehran School of Veterinary Medicine, Veterinary Teaching Hospital. The horse presented skin lesions around. In our survey, several raised granulomatous nodules with a cystic space and parasites within the cysts were observed. Also gastric rupture at greater curvature due to abscess and perforation through the serosa causing diffused peritonitis and subsequent death. Eosinophils and other inflammatory cells were present in large numbers. Furthermore, cutaneous lesions were characterized by single or multiple ulcerated timorous masses with eosinophil epithelioid cell infiltration and scattered necrotic debris. Granulation tissue and neutrophils were observed along the ulcerated area. In this report a case of cutaneous and gastric habronemiasis in a horse in Iran is described with special attention to confirmation of the clinical diagnosis. PMID:27605815

    Borroni, G; Grassi, S; Carugno, A

    2015-02-01

    The most recent pediatric vasculitis classifications (EULAR/PRINTO/PRES) have proposed the use of an integration of clinical signs and symptoms, laboratory data, imaging and pathologic data. Pediatric vasculitis represent a peculiar clinical-diagnostic model, compared to the corresponding adult pathology chapter, and in particular, dermatopathologic aspects of these diseases identify more specific issues, made contingent by crucial variables such as duration of vasculitis lesion, site of the biopsy, proper biopsy depth, and possibility to correlate histopathological findings with immunopathological results. Possible additional diagnostic difficulties may arise from the fact that, in children, the same systemic disease, such as lupus erythematosus, may present with different clinical manifestations, with histopathological features of a precise type of vasculitis specific for that type of clinical manifestation. Examples are provided by hypocomplementemic urticarial vasculitis, cryoglobulinemic purpura, lymphocytic vasculitis of livedoid lesions. This paper describes the cutaneous histopathological findings of some vasculitis related pediatric diseases, be they pertaining to a systemic vasculitis with corresponding cutaneous vasculitis, to a systemic vasculitis with sporadic cutaneous vasculitic involvement, and to a systemic vasculitis without cutaneous vasculitic involvement. Type and level of histopathological vasculitic involvement, caliber of the vessel, type of vasculitis associated infiltrate, are likewise reliable integration in the complex diagnostic path of vasculitis in childhood. On the basis of these criteria dermatopathologists should be confident in identifying the type of the vasculitis and relate them to a specific pediatric disease. PMID:25516220

    2009-03-01

    Angiosarcoma (AS) is a rare neoplasm. Cutaneous AS is the most common form of AS. The epithelioid variant of the disease, however, is a rare entity. This subset can histologically mimic non-vascular neoplasms and impose serious challenges in reaching the correct diagnosis. We present five patients with cutaneous epithelioid angiosarcoma (EAS); in none, the clinical diagnosis included a vascular lesion. Three patients had history of breast conservation surgery with/without radiation therapy. Other patients had no previous radiation, and there was no lymphedema in any of the cases. The histopathological examination of the biopsy specimens by hematoxylin and eosin method was not suggestive of a malignant vascular neoplasm initially and the differential diagnoses included carcinoma, malignant melanoma and atypical lymphoid infiltrate. Only after performing immunohistochemical studies that included vascular markers, a definitive diagnosis was possible. Some cases showed unusual histopathological features. Cutaneous EAS is a rare variant of cutaneous AS that can mimic a variety of more common, non-vascular neoplasms, creating a major pitfall in the diagnosis. A careful and thorough histopathological examination and a high index of suspicion, along with appropriate immunohistochemical evaluation, can help reach a correct diagnosis and provide optimal patient care.

  13. Sentinel lymph node biopsy in local recurrence of cutaneous melanoma

    International Nuclear Information System (INIS)

    Full text: Locally recurrent disease in patients with melanoma is usually defined as cutaneous or subcutaneous arising within 5 cm of the primary site after complete excision of the primary lesion. It may represent residual disease not excised with the primary tumor or the outgrowth of the satellite lesions, which are common with melanoma. Lymphatic mapping and sentinel lymph node (SLN) biopsy is highly accurate in staging nodal basins at risk of regional metastases in primary melanoma patients and identifies those who may benefit from earlier lymphadenectomy. Our purpose was to evaluate the efficacy of sentinel lymph node mapping and biopsy in local recurrence of cutaneous melanoma when the primary lesion was less than 1.0mm thick. Three patients with local recurrence of cutaneous melanoma underwent sentinel lymph node mapping and biopsy. All patients underwent preoperative lymphoscintigraphy to identify the lymphatic basin and the site of the sentinel node. All patients subsequently underwent intra-operative lymphatic mapping and selective lymph node biopsy with vital blue dye and hand-held gamma probe. Excised SLN were analysed by conventional histological staining (H and E) and immunohistochemical staining. In all patients the lymphatic mapping and sentinel lymph node biopsy was successful. The SLN biopsy was negative in two patients and positive in one who underwent therapeutic lymph node dissection. Our results indicate that the SLN mapping and biopsy is also possible in patients having local recurrence of cutaneous melanoma. Although long-term results are not available, early results are promising. (author)

    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.

    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.

    Full Text Available Abstract Background Pentavalent antimonials (Sb5 and miltefosine are the first-line drugs for treating cutaneous leishmaniasis in Colombia; however, toxicity and treatment duration negatively impact compliance and cost, justifying an active search for better therapeutic options. We compared the efficacy and safety of thermotherapy and meglumine antimoniate for the treatment of cutaneous leishmaniasis in Colombia. Method An open randomized Phase III clinical trial was performed in five military health centres. located in northwestern, central and southern Colombia. Volunteers with parasitological positive diagnosis (Giemsa-stained smears of cutaneous leishmaniasis were included. A single thermotherapy session involving the application of 50°C at the center and active edge of each lesion. Meglumine antimoniate was administered intramuscularly at a dose of 20 mg Sb5/kg weight/day for 20 days. Results Both groups were comparable. The efficacy of thermotherapy was 64% (86/134 patients by protocol and 58% (86/149 by intention-to-treat. For the meglumine antimoniate group, efficacy by protocol was 85% (103/121 patients and 72% (103/143 by intention-to-treat, The efficacy between the treatments was statistically significant (p 0.01 and Leishmania species responsible for infection. The side effects of meglumine antimoniate included myalgia, arthralgia, headache and fever. Regarding thermotherapy, the only side effect was pain at the lesion area four days after the initiation of treatment. Conclusion Although the efficacy rate of meglumine antimoniate was greater than that of thermotherapy for the treatment of cutaneous leishmaniasis, the side effects were also greater. Those factors, added to the increased costs, the treatment adherence problems and the progressive lack of therapeutic response, make us consider thermotherapy as a first line treatment for cutaneous leishmaniasis.

    Cutaneous body image, defined as the individual's mental perception of the appearance of their skin, hair and nails, is an important psychodermatological element in skin diseases. To measure individuals' cutaneous body image, a practical and accurate instrument is necessary. In this study, we translated the Cutaneous Body Image Scale (CBIS), a 7-item instrument originally created by Gupta et al. in 2004, into Japanese using a forward- and back-translation method and evaluated the reliability and validity of the instrument by psychometric tests. A total of 298 healthy adults (64 men and 234 women, aged 28.9 +/- 9.9 years) and 165 dermatology patients (56.7% eczema/dermatitis, 9.8% acne, 7.5% alopecia, 6.9% psoriasis, 19.1% skin tumor/fleck/other) (30 men and 135 women, aged 37.9 +/- 15.2 years) responded to the Japanese version of the CBIS. The internal-consistency reliability of the instrument was high (Cronbach's alpha, healthy adults 0.88, patients 0.84). The CBIS measure demonstrates good test-retest reliability (healthy adults gamma = 0.92, P Skindex-16 in healthy adults (gamma = -0.397 and -0.373, respectively) and in patients (gamma = -0.431 and -0.38, respectively). A stepwise multiple regression analysis revealed that an emotional aspect of skin-condition related quality of life was the best predictor of cutaneous body image in both healthy adults and patients (beta = -0.31 and -0.41, respectively) followed by "body dissatisfaction" (beta = -0.17, and -0.23, respectively). Adjusted R(2) was 0.246 in healthy adults and 0.264 in patients. These were consistent with the results from the original the CBIS. These results suggest that the Japanese version of the CBIS is a reliable and valid instrument to measure the cutaneous body image of Japanese adults and also dermatology patients. PMID:19712274

However, these methods rely on recovery of viable Bacillus anthracis cells from swabs of cutaneous lesions and often yield negative results. This study developed a rapid protocol for detection of B. anthracis on clinical swabs. Three types of swabs, flocked-nylon, rayon, and polyester, were evaluated by 3 extraction methods, the swab extraction tube system (SETS), sonication, and vortex. Swabs were spiked with virulent B. anthracis cells, and the methods were compared for their efficiency over time by culture and real-time PCR. Viability testing indicated that the SETS yielded greater recovery of B. anthracis from 1-day-old swabs; however, reduced viability was consistent for the 3 extraction methods after 7 days and nonviability was consistent by 28 days. Real-time PCR analysis showed that the PCR amplification was not impacted by time for any swab extraction method and that the SETS method provided the lowest limit of detection. When evaluated using lesion swabs from cutaneous anthrax outbreaks, the SETS yielded culture-negative, PCR-positive results. This study demonstrated that swab extraction methods differ in their efficiency of recovery of viable B. anthracis cells. Furthermore, the results indicated that culture is not reliable for isolation of B. anthracis from swabs at ≥ 7 days. Thus, we recommend the use of the SETS method with subsequent testing by culture and real-time PCR for diagnosis of cutaneous anthrax from clinical swabs of cutaneous lesions. PMID:23035192

  6. Treatment and follow-up of patients suffering from the cutaneous radiation syndrome

    International Nuclear Information System (INIS)

    inflammation were stopped. The most remarkable result was the reduction of radiation fibrosis: sonographically determined skin thickness partly returned to normal levels after treatment of months with Interferon gamma 50μg s.c. 3 week. Based upon therapeutic experience with patients undergoing radiation therapy, symptomatic relief of pruritus can be achieved by administration of nonsedating antihistamines, such as Loratadine. In the chronic stage of the CRS after radiation therapy, where interferon gamma cannot be used, reduction of radiation-induced cutaneous fibrosis can be reached by a combination of Vitamin E and pentoxyfiline even two decades after radiation exposure. It is concluded that under accidental partial body exposure with high doses of beta and gamma irradiation, the predominant involvement of the skin, described as the cutaneous radiation syndrome, may become the characteristic trait of this increasingly probable accident pattern. Through treatment is complex and requires dermatological and radiobiological expertise, it results in marked clinical improvement of the affected patients. These results demonstrate that considerable progress has been achieved during the last years regarding diagnosis and treatment of cutaneous radiation sequelae. Surgery has to be considered the treatment of choice for radiation carcinoma, but is no longer the only available therapeutic option. However, systematic controlled clinical trials are still missing for these options

    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.

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

    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.

    2013-11-01

    Estimated worldwide incidence of tegumentary leishmaniasis (cutaneous leishmaniasis [CL] and mucocutaneous leishmaniasis [MCL]) is over 1.5 million cases per year in 82 countries, with 90 % of cases occurring in Afghanistan, Brazil, Iran, Peru, Saudi Arabia and Syria. Current treatments of CL are poorly justified and have sub-optimal effectiveness. Treatment can be based on topical or systemic regimens. These different options must be based on Leishmania species, geographic regions, and clinical presentations. In certain cases of Old World CL (OWCL), lesions can spontaneously heal without any need for therapeutic intervention. Local therapies (thermotherapy, cryotherapy, paromomycin ointment, local infiltration with antimonials) are good options with less systemic toxicity, reserving systemic treatments (azole drugs, miltefosine, antimonials, amphotericin B formulations) mainly for complex cases. The majority of New World CL (NWCL) types require systemic treatment (mainly with pentavalent antimonials), either to speed the healing or to prevent dissemination to oral-nasal mucosa as MCL (NWMCL). These types of lesions are potentially serious and always require systemic-based regimens, mainly antimonials and pentamidine; however, the associated immunotherapy is promising. This paper is an exhaustive review of the published literature on the treatment of OWCL, NWCL and NWMCL, and provides treatment recommendations stratified according to their level of evidence regarding the species of Leishmania implicated and the geographical location of the infection.

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

    2002-01-01

    Animal studies suggest that alpha-adrenergic-mediated vasoconstriction is compromised during whole-body heating. The purpose of this study was to identify whether whole-body heating and/or local surface heating reduce cutaneous alpha-adrenergic vasoconstrictor responsiveness in human skin. Protocol I: Six subjects were exposed to neutral skin temperature (i.e., 34 degrees C), whole-body heating, and local heating of forearm skin to increase skin blood flow to the same relative magnitude as that observed during whole-body heating. Protocol II: In eight subjects forearm skin was locally heated to 34, 37, 40, and 42 degrees C. During both protocols, alpha-adrenergic vasoconstrictor responsiveness was assessed by local delivery of norepinephrine (NE) via intradermal microdialysis. Skin blood flow was continuously monitored over each microdialysis membrane via laser-Doppler flowmetry. In protocol I, whole-body and local heating caused similar increases in cutaneous vascular conductance (CVC). The EC50 (log NE dose) of the dose-response curves for both whole body (-4.2 +/- 0.1 M) and local heating (-4.7 +/- 0.4 M) were significantly greater (i.e., high dose required to cause 50% reduction in CVC) relative to neutral skin temperature (- 5.6 +/- 0.0 M; Pbody heated conditions CVC did not return to pre-heating values even at the highest dose of NE. In protocol II, calculated EC50 for 34, 37, 40, and 42 degrees C local heating was - 5.5 +/- 0.4, -4.6 +/- 0.3, -4.5 +/- 0.3, - 4.2 +/- 0.4 M, respectively. Statistical analyses revealed that the EC50 for 37,40 and 42 degrees C were significantly greater than the EC50 for 34 degrees C. These results indicate that even during administration of high concentrations of NE, alpha-adrenergic vasoconstriction does not fully compensate for local heating and whole-body heating induced vasodilatation in young, healthy subjects. Moreover, these data suggest that elevated local temperatures, above 37 degrees C, and whole-body heating

    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

    2014-01-01

    A 14-year-old boy presented with a chronic history of atypical papular mucinosis consisting of multiple subcutaneous nodules and confluent papular skin lesions. He initially presented at age 2 years with the rapid onset of numerous subcutaneous nodular lesions that completely resolved over a period of years. Clinical and histologic evidence, together with his clinical course, were suggestive of self-healing juvenile cutaneous mucinosis (SHJCM), but a few years later, during childhood, he experienced a recurrence of the subcutaneous nodules involving the limbs, trunk, and face, in addition to new findings of multiple flesh-colored papules coalescing into plaques on his neck and back. Although his early childhood course and histologic picture were suggestive of SHJCM, the progressive nature of his disorder is not like that seen in SHJCM and appears different from other reported disorders involving cutaneous mucinosis.

    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.

    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.

    Reverse total shoulder arthroplasty is becoming a common form of shoulder arthroplasty that is often performed in the setting of rotator cuff pathology. Infection is a rare complication but is more common in reverse total shoulder arthroplasty than in hemiarthroplasty or anatomic total shoulder arthroplasty. We present the case of a 69-year-old patient with a reverse total shoulder arthroplasty who presented with purulent drainage from the skin of his anterior shoulder. Computed tomography arthrogram confirmed the presence of a synovial cutaneous fistula. Synovial cutaneous fistula is a rare variant of periprosthetic infection that, to our knowledge, has not been described previously in the setting of a reverse total shoulder arthroplasty. Computed tomography arthrogram proved to be a reliable method for confirming the diagnosis and was used for operative planning to remove the hardware. PMID:27257460

    Full Text Available A 45-year-old man with reactivation of previously existing and subsiding cutaneous leishmaniasis on his wrist and lower leg (shin after renal transplantation was admitted to our dermatology service on March 2008. He presented to us with two huge tumoral and cauliflower-like lesions. Skin smear and histopathology of skin showed leishman bodies and confirmed the diagnosis. After renal transplantation, he received cyclosporine plus prednisolone to induce immunosuppression and reduce the probability of transplant rejection. After immunosuppressive therapy, reactivation of cutaneous leishmaniasis with the above presentation took place. The patient responded to 800 mg/day intravenous sodium stibogluconate for 3 weeks plus local cryotherapy. Systemic plus local therapy along with reducing the doses of immunosuppressive drugs led to improvement of lesions. Reactivation of leishmaniasis after immunosuppression has been rarely reported.

    2011-01-01

    Full Text Available Congenital cutaneous candidiasis (CCC is an extremely rare disorder that presents within the first 6 days of life. The manifestations ranges from diffuse skin eruption without any systemic symptoms to respiratory distress, hepatosplenomegaly, sepsis, and death. We report a neonate who presented with generalized skin eruptions at birth, characterized by erythematous macules and papules. The eruption involved head, face, neck, trunk, and extremities. Candida albicans was demonstrated on direct KOH smear, skin biopsy. The disease implies a congenital intrauterine infection and is different from neonatal candidiasis, which manifests as thrush or diaper dermatitis. The infection is acquired from the maternal genital tract in an ascending fashion. Clinical features, direct smear examination of specimen, and appropriate cultures are useful in differentiating the lesions from other more common dermatoses of the neonatal period. Topical antifungal therapy is sufficient unless systemic candidiasis is present. Prognosis for congenital cutaneous candidiasis is good.

    2016-06-17

    Complications due to cocaine are a public health problem. The typical cutaneous disease is leukocytoclastic vasculitis and/or thrombotic vasculopathy affecting mainly the ears. No intense systemic involvement is usually present, but there may be several cutaneous, mucosal and systemic manifestations. Other findings associated as arthralgia, neutropaenia or agranulocytosis, low titer positive antinuclear antibodies, antiphospholipid antibody positivity and neutrophil cytoplasmic antibodies against multiple antigens help the diagnosis. This disease requires a clinical suspicion with a clinical history, a complete physical examination and a broad differential diagnosis for an early and correct diagnosis. The course is usually self-limited. In most cases the only treatment is to discontinue the use of cocaine associated with symptomatic treatment, no proven benefit of systemic corticosteroids.

    2016-04-01

    Cellular schwannoma and pseudoglandular schwannoma are both previously described rare variants of schwannoma. The authors present an unusual case of a cellular spindle cell neoplasm with prominent gland-like structures, having features of both variants. The nature of this lesion was confirmed by histology and immunohistochemistry, with diffuse and strong S100 and membranous collagen type IV staining. The gland-like structures were lined by S100 + cells and contained proteinaceous, mucicarmine-negative material, supporting a degenerative, not true glandular, phenomenon. This is the first case of a cutaneous schwannoma demonstrating both marked cellularity and pseudoglandular formation, which the authors have designated cutaneous cellular pseudoglandular schwannoma. Recognition of this extremely rare variant will help avoid diagnostic confusion and overtreatment of this benign entity. PMID:26844614

    2014-06-01

    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.

    2014-01-01

    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.

    2016-02-01

    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.

    Primary cutaneous anaplastic large-cell lymphoma (PCALCL) is a part of the spectrum of CD30+ lymphoproliferative cutaneous processes. The characteristics include single or multifocal nodules that ulcerate as skin lesion, slow disease progression, autoregressive, and recurrent in few years. The present study report the case of a 16-year-old boy presenting PCALCL with single nodules, ulcer, keloid, and scab in his right-side face. He showed a good response to the treatment with systemic chemotherapy and dermatoplasty, and regained confidence after the appearance of recovery. There is no relapse of the primary lesion and organs involved till now. The chemotherapy combining with surgical excision and dermatoplasty is a good method for PCALCL, per the lesion biopsy and positron emission tomography-computed tomography before and after treatment.

    1997-01-01

    The occurrence of cutaneous haemangiomas in chickens is described. Macroscopi-cally these lesions appeared as a marked redness of the skin, affecting in particular the pericloacal area. Histologically, they resembled capillary haemangiomas, characterized by the proliferation of newly-formed blood vessels. The proliferating cells were of endothelial origin, as demonstrated by ultrastructural observations and by the positivity of the proliferating cells to staining with specific markers (lectins and anti factor VIII-related antigen antibodies).

    2016-01-01

    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.

    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)

  13. Leishmania serology in the diagnosis of cutaneous leishmaniasis

    International Nuclear Information System (INIS)

    Background: The gold standard to diagnose cutaneous leishmaniasis is histopathology, but there has always been a need of a rapid, reliable, cheap and convenient laboratory investigation. Serological tests fulfill the above criteria. Objective: The objective of the study was to determine the sensitivity and specificity of enzyme linked immunosorbent assay (ELISA) in detection of leishmania antibodies, in comparison with the histopathology. Place and duration of study: The study was conducted in Military Hospital Rawalpindi from 1st November 2010 to 30th June 2011. Patients and methods: The study population included the patients who were clinically diagnosed with cutaneous leishmaniasis. All of them were biopsied and serum was sent for leishmania serology. Results: A total of 47 patients were included. They were all adult males. The histopathology was positive in 31/47 patients (65.95%), while the leishmania serology was positive in 36/47 cases (76.59%). The sensitiuites was 74.19%, specificity was 18.75%, positive predictive value has 63.88%, negative predicative value was 27% and accuracy was 55%. Conclusion: In the light of sensitivity analysis, it may be concluded that leishmania serology has moderate sensitivity and low specificity; hence it is not a reliable test for cutaneous leishmaniasis.

    2015-04-01

    Antibiotics are being successfully used to fight many infectious diseases caused by pathogenic microorganisms. However, new infectious diseases are continuously being identified, and some known pathogens are becoming resistant against known antibiotics. Furthermore, many antifungals are causing serious side effects in long-term treatments of patients, and many skin infections caused by dermatophytes are difficult to cure. The beneficial roles of resident cutaneous microbiota to inhibit pathogenic microorganisms have been shown for many vertebrate species. Microbial symbionts on the amphibian skin for example can be a source of powerful antimicrobial metabolites that can protect amphibians against diseases, such as chytridiomycosis, caused by a fungal pathogen. In this research, we investigated whether cutaneous bacterial species isolated from Lithobates catesbeianus (North American bullfrog), an invasive amphibian species that is resistant to chytridiomycosis, produce secondary metabolites that can be used to inhibit the growth of three species of dermatophytes (Microsporum gypseum, Epidermophyton floccosum, and Trichophyton mentagrophytes) which are known to cause topical or subdermal skin infections in humans. Strongly anti-dermatophyte bacterial species that belonged to the Bacillaceae, Streptomycetaceae, Pseudomonadaceae, Xanthomonadaceae, Aeromonadaceae, and Enterobacteriaceae were identified. This research has provided evidence of the presence of cutaneous anti-dermatophyte bacteria from L. catesbeianus which might provide a basis for health care providers to experiment with new antifungals in the future.

    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.

    The increasingly aged population worldwide means more people are living with chronic diseases, reduced autonomy, and taking various medications. Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the literature from 2004 to 2014 using PubMed was performed by a working group of six European dermatologists with clinical and research experience in dermatology. Basic topical therapy can restore and protect skin barrier function, which relieves problems associated with xerosis, prevents aggravating moisture-associated skin damage, and enhances quality of life. In conclusion, the authors provide physicians with practical recommendations to assist them in implementing basic skin care for the elderly in an integrated care approach. PMID:26929610

  19. Cutaneous metastasis as the first sign of lung cancer

    Directory of Open Access Journals (Sweden)

    Ðurić Milivoje

    2013-01-01

    Full Text Available Cutaneous metastases of lung tumors are occurring in 1-12% of cases. High prevalence of lung cancer increases the likelihood of finding these changes in clinical practice. They are usually in the form of a firm, mobile and painless nodule on the head, neck and chest, and their appearance is a sign of advanced disease. Cutaneous metastases are rarely the first sign of malignancy. A 62-year-old patient presented to her doctor a fast-growing nodule on the forehead. Extirpation of the nodule and further diagnosis showed that it was a metastasis of small cell lung cancer localized in the right lung with extensive metastases to the contralateral lung, liver and spine. Cutaneous metastases may be the first sign of malignancy or the first sign of progression of already diagnosed malignancy. A diagnosis of metastatic disease should be considered in patients with risk factors or a known cancer. The presence of a skin metastasis in a patient with a lung cancer indicates poor prognosis.

    Full Text Available Epilepsy is one of the most common neurologic disorders in dogs and life-long treatment with antiepileptic drugs (AED is frequently required. Adverse events of antiepileptic drugs targeting the skin are only rarely reported in veterinary medicine and the true incidence and spectrum of cutaneous reactions in epileptic dogs remains unknown. In this study we hypothesized that cutaneous reactions commonly occur in epileptic dogs and are related to AED treatment. A retrospective case review of 185 dogs treated for epilepsy identified 20.0% with simultaneous appearance of dermatologic signs. In a subsequent prospective case investigation (n=137 we identified newly appearing or distinct worsening of skin lesions following initiation of antiepileptic drug therapy in 10.9% of dogs treated for epilepsy (95% CI 6.8- 17.7%. Cutaneous lesions were classified as probably drug-induced in 40.0% of these cases. Patch-testing and intradermal testing was further investigated as potential diagnostic methods to confirm antiepileptic drug hypersensitivity. They were of high specificity but sensitivity and positive predictive value appeared inappropriate to recommend their routine use in clinical practice.

    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.

  3. Alternating-pulse iontophoresis for targeted cutaneous anesthesia

    Science.gov (United States)

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

    2003-01-01

    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.

    The recently developed technique for measuring cutaneous mitochondrial oxygen tension (mitoPO2) by means of the Protoporphyrin IX-Triplet State Lifetime Technique (PpIX-TSLT) provides new opportunities for assessing mitochondrial function in vivo. The aims of this work were to study whether cutaneous mitochondrial measurements reflect mitochondrial status in other parts of the body and to demonstrate the feasibility of the technique for potential clinical use. The first part of this paper demonstrates a correlation between alterations in mitochondrial parameters in skin and other tissues during endotoxemia. Experiments were performed in rats in which mitochondrial dysfunction was induced by a lipopolysaccharide-induced sepsis (n = 5) and a time control group (n = 5). MitoPO2 and mitochondrial oxygen consumption (mitoVO2) were measured using PpIX-TSLT in skin, liver and buccal mucosa of the mouth. Both skin and buccal mucosa show a significant mitoPO2-independent decrease (P paper describes the clinical concept of monitoring cutaneous mitochondrial respiration in man. A first prototype of a clinical PpIX-TSLT monitor is described and its usability is demonstrated on human skin. We expect that clinical implementation of this device will greatly contribute to our understanding of mitochondrial oxygenation and oxygen metabolism in perioperative medicine and in critical illness. Our ultimate goal is to develop a clinical monitor for mitochondrial function and the current results are an important step forward. PMID:25388510

  13. Cutaneous reaction to radiation and their treatment

    International Nuclear Information System (INIS)

    Acute radiation dermatitis were reported of iridium 172 under poor administration which radiated locally on the skin of hands and fingers of oil company workers. Atomic bomb over Hiroshima and Nagasaki killed many people by total body skin exposure. Many workers and firemen were radiated by beta and gamma rays in the Chernobyl' accident, where 19 of 28 death cases died by radiation burn. 8 patients with 60-100% burn area died in 15-24 days after the explosion. Of 12 patients with 30-60% burn area, 6 died by burn. 21 cases of 30% burn area did not die in spite of mild or severe bone marrow depression. In all these cases, areas of skin ulcers epithelized with dry and wet scales till 50-60 days after the explosion, except large area (20-25cm2) transplanted. In this accident, severe radiation burn due to the beta ray irradiation occured with endogeneous intoxication, renal disturbance, blood biochemical changes and bleeding. Oral, pharyngeal and intestinal membrane were irradiated by beta ray and were ulcerated so they could hardly eat. The treatment of these cases with acute radiation dermatitis should be performed by the procedure of treatment of burn, locally and systematically. Local treatment should be performed by topical application of antibiotic ointment or adrenocortical steroid ointment with antibiotics. In severe burn, systemic treatment with plasma and other fluids for burn shock should be performed, corresponding to the area and depth of radiation burn. (A.Y.)

    To retrospectively access the outcome and toxicity of a total skin electron beam therapy (TSEBT) in patients with cutaneous lymphoma (CL) or leukemia. Treatment results of 25 patients (median age 63 years; 5 female, 20 male) with cutaneous manifestations of advanced and therapy-refractory CL (n = 21; T-cell lymphomas n = 18, B-cell lymphomas n = 3) stage IIB-IV or leukemia (n = 4; AML n = 2, CLL n = 1, PDC n = 1) treated between 1993 and 2010 were reviewed. All patients were symptomatic. The median total dose was 29Gy, applied in 29 fractions of median 1 Gy each. The median follow-up was 10 months. Palliation was achieved in 23 patients (92%). A clinical complete response was documented in 13 (52%) and a partial response in 10 patients (40%). The median time to skin progression was 5 months (range 1–18 months) and the actuarial one-year progression-free survival 35%. The median overall survival (OS) after the initiation of TSEBT was 10 months (range 1–46 months) and the actuarial one-year OS 45%. TSEBT related acute adverse events (grade 1 or 2) were observed in all patients during the treatment period. An acute grade 3 epitheliolysis developed in eight patients (32%). Long-term adverse events as a hyperpigmentation of the skin (grade 1 or 2) were documented in 19 patients (76%), and a hypohidrosis in seven patients (28%). For palliation of symptomatic cutaneous manifestations of advanced cutaneous lymphoma or leukemia, total skin electron beam therapy is an efficient and well tolerated considerable treatment option

    2013-10-01

    Full Text Available Skin tumors occurring on the scleroderma fingers are rarely seen. Swollen fingers are hallmarks of systemic sclerosis, and mucin deposition in the lesional skin is a constant feature in systemic sclerosis. Here we describe a case of cutaneous myxoid cyst on the flexor aspect of the sclerotic fingers in a patient with severe diffuse cutaneous systemic sclerosis. Cutaneous myxoid cyst is a relatively common benign tumor; however, cases of cutaneous myxoid cysts developing on the scleroderma fingers have not been reported to date. Mucin deposition in the sclerotic skin may be a predisposing factor in the induction of myxoid cyst on the scleroderma finger in our patient.

    2010-07-01

    Recently, we identified an AP-1-dependent target gene in 12-O-tetradecanoylphorbol-13-acetate (TPA)-treated mouse back skin, which encodes a retroviral-like aspartic proteinase (Taps/Asprv1). Taps expression was detected almost exclusively in stratified epithelia of mouse embryos and adult tissues, and enhanced protein levels were present in several non-neoplastic human skin disorders, implicating a crucial role for differentiation and homeostasis of multilayered epithelia. Here, we generated a mouse model in which Taps transgene expression is under the control of the human ubiquitin C promoter (UBC-Taps). Although no obvious phenotype was observed in normal skin development and homeostasis, these mice showed a significant delay in cutaneous wound closure compared with control animals. Shortly after re-epithelialization, we found an increase in keratinocytes in the stratum granulosum, which express Filaggrin, a late differentiation marker. A hypergranulosum-like phenotype with increased numbers of Filaggrin-positive keratinocytes was also observed in UBC-Taps mice after administration of TPA. In summary, these data show that aberrant Taps expression causes impaired skin regeneration and skin remodeling after cutaneous injury and chemically induced hyperplasia. PMID:20237492

    Leishmaniaparasites cause a broad range of disease, with cutaneous afflictions being, by far, the most prevalent. Variations in disease severity and symptomatic spectrum are mostly associated to parasite species. One risk factor for the severity and emergence of leishmaniasis is immunosuppression, usually arising by coinfection of the patient with human immunodeficiency virus (HIV). Interestingly, several species ofLeishmaniahave been shown to bear an endogenous cytoplasmic dsRNA virus (LRV) of theTotiviridaefamily, and recently we correlated the presence of LRV1 withinLeishmaniaparasites to an exacerbation murine leishmaniasis and with an elevated frequency of drug treatment failures in humans. This raises the possibility of further exacerbation of leishmaniasis in the presence of both viruses, and here we report a case of cutaneous leishmaniasis caused byLeishmania braziliensisbearing LRV1 with aggressive pathogenesis in an HIV patient. LRV1 was isolated and partially sequenced from skin and nasal lesions. Genetic identity of both sequences reinforced the assumption that nasal parasites originate from primary skin lesions. Surprisingly, combined antiretroviral therapy did not impact the devolution ofLeishmaniainfection. TheLeishmaniainfection was successfully treated through administration of liposomal amphotericin B.

    Background: the concurrent administration of cetuximab to radiotherapy has recently been shown to improve the clinical outcome of head-and-neck cancer (HNC) patients. An aggravation of the radiation-induced skin toxicity was not described. Here, however, two cases with severe skin toxicity during the combined treatment are reported. Clinical observations: in a small group of five patients with locally advanced HNC treated with irradiation and concurrent cetuximab, two cases of unusually severe radiation dermatitis were observed. Both patients developed confluent moist desquamations confined to the irradiation field at a dose of 40 Gy (CTC - Common Toxicity Criteria, grade 3), which progressed into an ulcerative dermatitis (grade 4) at 58 Gy and 46 Gy, respectively. Histopathology showed a vacuolic degeneration of basal keratinocytes, subepidermal blister formation, and mixed perivascular and interstitial inflammatory infiltrates leading to a complete loss of the epidermis. These cutaneous side effects led to the discontinuation of radiotherapy. Topical corticosteroids and systemic antibiotic treatment resulted in wound healing, which allowed the continuation of radiotherapy. Conclusion: these findings indicate that cetuximab may have the potential to enhance the severity of radiation dermatitis in HNC patients. A systematic monitoring of cutaneous side effects during radiotherapy plus cetuximab is advised in order to reliably estimate the frequency of severe (grade 3/4) radiation dermatitis. (orig.)

    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.

    The use of topical nonsteroidal anti-inflammatory drugs is widespread (particularly in countries bordering the Mediterranean). Compared to their wide use, the incidence of published adverse cutaneous effects appears minimal, although they are increasing. Most of them are a form of allergic contact dermatitis (ACD). Multiple sensitization and/or cross-reactions are rarely reported. Interestingly, our patient presented ACD with diclofenac and etofenamate (both from different chemical groups) and, furthermore, patch tests were positive with bencydamine and indomethacin (both indolacetic acid derivatives), piroxicam and fepradinol. We think that our results could not be explained due to cross-reactivity, and that multiple sensitization was more likely. PMID:8864624

  12. Pharmacokinetic of antimony in mice with cutaneous Leishmaniasis

    International Nuclear Information System (INIS)

    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+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 122Sb and 124Sb.

    2016-01-01

    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.

    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.

    2015-06-01

    Cutaneous leishmaniasis is a parasitic infection caused by protozoa of the Leishmania genus that presents as asymptomatic pink papules that may ulcerate. There are several species of Leishmania found in 98 endemic countries and whereas all are associated with cutaneous disease, only specific species can cause mucocutaneous or visceral disease. Although the diagnosis of cutaneous leishmaniasis can be confirmed with Giemsa staining of a biopsy or "touch prep" specimen, only speciation at specialized centers such as the Centers for Disease Control (CDC) can determine the risk of mucocutaneous or visceral disease. Treatment of cutaneous leishmaniasis is varied and depends on the extent of cutaneous disease and the risk of mucocutaneous or visceral disease. PMID:26158361

    2010-01-01

    Full Text Available Cutaneous leishmaniasis is a disease endemic to Central and South America, Mexico and the Caribbean, and affects millions of people. As travel to these regions becomes more common, cutaneous leishmaniasis is becoming a disease of increasing importance in the developed world. However, disease recognition and access to appropriate therapy for cutaneous leishmaniasis remains a challenge in North America. The present article reports a case of cutaneous leishmaniasis in a Canadian man following a trip to Costa Rica. Species-specific diagnosis was confirmed by polymerase chain reaction analysis of a skin biopsy, which was positive for Leishmania panamensis. After failing a course of itraconazole, the patient was successfully treated with sodium stibogluconate, despite significant barriers to administering this therapy, and the paucity of data regarding its efficacy and tolerability. The pathophysiology, diagnosis and systemic treatment of cutaneous leishmaniasis, as well as its emerging presence in the developed world, are reviewed.

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

    2016-06-01

    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.

    A cutaneous ciliated cyst is a rare entity found predominantly in the lower extremities and perineal region of young females. Although initially described by Hess in 1890, the present day term, "cutaneous ciliated cyst," was proposed by Farmer in 1978 and includes a wide array of cyst types. Despite their typical female predominance and location, many have described cutaneous ciliated cysts in males and atypical locations. In addition, Mullerian cysts in the posterior mediastinum and the retroperitoneum have been reported. To date, only 40 cases have been reported in the literature of a Mullerian-type, cutaneous ciliated cyst. Here, we report a case of 13-year-old female with one in the gluteal cleft, initially presenting as a pilonidal cyst. We also discuss the differential diagnosis of pediatric sacrococcygeal lesions and pathogenesis of a Mullerian-type, cutaneous ciliated cyst. PMID:23913265

    Exposure to solar ultraviolet (UV) radiation is a causative factor in skin photodamage and carcinogenesis, and an urgent need exists for improved molecular photoprotective strategies different from (or synergistic with) photon absorption. Recent studies suggest a photoprotective role of cutaneous gene expression orchestrated by the transcription factor NRF2 (nuclear factor-E2-related factor 2). Here we have explored the molecular mechanism underlying carotenoid-based systemic skin photoprotection in SKH-1 mice and provide genetic evidence that photoprotection achieved by the FDA-approved apocarotenoid and food additive bixin depends on NRF2 activation. Bixin activates NRF2 through the critical Cys-151 sensor residue in KEAP1, orchestrating a broad cytoprotective response in cultured human keratinocytes as revealed by antioxidant gene expression array analysis. Following dose optimization studies for cutaneous NRF2 activation by systemic administration of bixin, feasibility of bixin-based suppression of acute cutaneous photodamage from solar UV exposure was investigated in Nrf2(+/+) versus Nrf2(-/-) SKH-1 mice. Systemic administration of bixin suppressed skin photodamage, attenuating epidermal oxidative DNA damage and inflammatory responses in Nrf2(+/+) but not in Nrf2(-/-) mice, confirming the NRF2-dependence of bixin-based cytoprotection. Taken together, these data demonstrate feasibility of achieving NRF2-dependent cutaneous photoprotection by systemic administration of the apocarotenoid bixin, a natural food additive consumed worldwide.

    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. PMID:27252259

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

    International Nuclear Information System (INIS)

    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

    The purpose is to present the first report and describe our novel technique for intracorporeal continent cutaneous diversion after robotic cystectomy. After completion of robot-assisted cystectomy using a standard six-port transperitoneal technique, three additional ports are placed, and the robot is redocked laterally over the patient's right side in the modified lateral position. Our technique replicates step-by-step the principles of the open approach. Ileocolonic anastomosis, ureteroenteral anastomoses, and construction of a hand-sewn right colonic pouch are all performed intracorporeally. Tapering of efferent ileal limb and reinforcement of the ileocecal valve are performed via the extraction site, while the stoma is matured through a prospective port site. Successful robotic intracorporeal creation of a modified Indiana pouch was achieved. Operative time for diversion was 3 hours, with negligible blood loss, and without any intraoperative complications. No major (Clavien III-V) 90-day complications were observed. At a follow-up of 1 year, the patient continues to catheterize without difficulty. We demonstrate the first description of robotic intracorporeal continent cutaneous urinary diversion after robot-assisted cystectomy. We present a systematic minimally invasive approach, replicating the principles of open surgery, which is technically feasible and safe with a good functional result. PMID:25556514

    2014-04-01

    Cutaneous collagenous vasculopathy (CCV) is a rare cutaneous microangiopathy that clinically resembles generalized essential telangiectasia with only 12 cases reported to date. The perivascular fibrosis is thought to be due to production of abnormal collagen by veil cells in the outer vessel walls as a result of unknown factors. This report is of an 84-year-old male with progressive telangiectasia. Biopsies showed characteristic features of CCV. In addition, there were multiple intravascular fibrin thrombi, some organizing and associated with endothelial cell hyperplasia with recanalization reminiscent of glomeruloid bodies and simulating reactive angioendotheliomatosis (RAE). Histochemically and ultrastructurally fibrin was noted within the vessel walls integrating into the fibrous tissue around the vessels; however, the patient had no evidence of coagulation disorder, cryoglobulinemia or cold agglutinemia. Immunofluorescence showed fibrinogen within the vessel walls but no immunoglobulins or C3. As well, there were minimal inflammatory cells. This suggests pauci-inflammatory injury to the endothelial cells by unknown angiogenic factors causing local intravascular fibrin thrombi with fibrin leaking and incorporating into the vessel walls, eventually leading to reparative perivascular fibrosis. This case suggests that some cases of CCV are related to a primary local intravascular occlusive thrombotic microangiopathy. However, the primary triggering factor causing the endothelial cell damage has yet to be elucidated. PMID:24350781

    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.

    The tumor microenvironment plays an important role in the progression of melanoma, the prototypical immunologic cutaneous malignancy. The triggering receptor expressed on myeloid cells (TREM) family of innate immune receptors modulates inflammatory and innate immune signaling. It has been investigated in various neoplastic diseases, but not in melanoma. This study examines the expression of TREM-1 (a proinflammatory amplifier) and TREM-2 (an anti-inflammatory modulator and phagocytic promoter) in human cutaneous melanoma and surrounding tissue. Indirect immunofluorescence staining was performed on skin biopsies from 10 melanoma patients and staining intensity was semiquantitatively scored. Expression of TREM-1 and TREM-2 was higher in keratinocytes than melanoma tissue (TREM-1: p < 0.01; TREM-2: p < 0.01). Whereas TREM-2 was the dominant isoform expressed in normal keratinocytes, TREM-1 expression predominated in melanoma tissue (TREM-1 to TREM-2 ratio: keratinocytes = 0.78; melanoma = 2.08; p < 0.01). The increased TREM ratio in melanoma tissue could give rise to a proinflammatory and protumor state of the microenvironment. This evidence may be suggestive of a TREM-1/TREM-2 paradigm in which relative levels dictate inflammatory and immune states, rather than absolute expression of one or the other. Further investigation regarding this paradigm is warranted and could carry prognostic or therapeutic value in treatment for melanoma. PMID:26184544

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.

    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.

    The skin is a highly sensitive organ. It is densely innervated with different types of sensory nerve endings, which discriminate between pain, temperature and touch. Autonomic nerve fibres which completely derive from sympathetic (cholinergic) neurons are also present. During all the phases of skin wound healing (inflammatory, proliferative and remodelling phases), neuromediators are involved. Several clinical observations indicate that damage to the peripheral nervous system influences wound healing, resulting in chronic wounds within the affected area. Patients with cutaneous sensory defects due to lepromatous leprosy, spinal cord injury and diabetic neuropathy develop ulcers that fail to heal. In addition, numerous experimental observations suggest that neurogenic stimuli profoundly affect wound repair after injury and that delayed wound healing is observed in animal models after surgical resection of cutaneous nerves. All these observations clearly suggest that innervation and neuromediators play a major role in wound healing. Interactions between neuromediators and different skin cells are certainly crucial in the healing process and ultimately the restoration of pain, temperature, and touch perceptions is a major challenge to solve in order to improve patients' quality of life.

    Aerosolized medications maximize clinical benefit by targeting the airways and minimize side effects by reducing (though not eliminating) systemic exposure. Aerosolized drugs delivered with a facemask may inadvertently deposit on the face and in the eyes, raising concerns about cutaneous and ocular side effects with these drugs. Cases of anisocoria have been reported from exposure of the eyes to aerosol bronchodilators. Whether inhaled corticosteroids (ICS) can cause skin and eye problems like those seen with systemic or topical steroids is more difficult to answer. Patients who take ICS may have other corticosteroid exposures, or have other conditions that predispose them to side effects, making the analysis of the ICS risk challenging. Also, many studies were not designed to search for cutaneous or ocular effects, or may have been too short to detect these effects. Nevertheless, ICS have been associated with an increased risk of skin thinning, bruising, cataracts and possibly glaucoma in adults, but not in children. The risks increase with advanced age, higher doses, and longer duration of use. In children, the risks of cataracts and glaucoma were negligible with ICS, whether a mouthpiece or a mask interface was used. Side effects like skin rash and conjunctivitis occurred at low frequencies similar to placebo or comparator drugs. We do not know whether exposed children will have increased risks from ICS later in life. Therefore, it is wise to avoid face and eye deposition when possible, and to use the minimally effective dose. PMID:17411401

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

    Full Text Available 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.

    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.

    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.

  15. Primary Cutaneous Peripheral T-Cell Lymphoma Not Otherwise Specified: A Rapidly Progressive Variant of Cutaneous T-Cell Lymphoma

    2015-01-01

    Full Text Available Primary Cutaneous Peripheral T-Cell Lymphoma NOS (PTL-NOS is a rare, progressive, fatal dermatologic disease that presents with features similar to many common benign plaque-like skin conditions, making recognition of its distinguishing features critical for early diagnosis and treatment (Bolognia et al., 2008. A 78-year-old woman presented to ambulatory care with a single 5 cm nodule on her shoulder that had developed rapidly over 1-2 weeks. Examination was suspicious for malignancy and a biopsy was performed. Biopsy results demonstrated CD4 positivity, consistent with Mycosis Fungoides with coexpression of CD5, CD47, and CD7. Within three months her cancer had progressed into diffuse lesions spanning her entire body. As rapid progression is usually uncharacteristic of Mycosis Fungoides, her diagnosis was amended to PTL-NOS. Cutaneous T-Cell Lymphoma (CTCL should be suspected in patients with patches, plaques, erythroderma, or papules that persist or multiply despite conservative treatment. Singular biopsies are often nondiagnostic, requiring a high degree of suspicion if there is deviation from the anticipated clinical course. Multiple biopsies are often necessary to make the diagnosis. Physicians caring for patients with rapidly progressive, nonspecific dermatoses with features described above should keep more uncommon forms of CTCL in mind and refer for early biopsy.

    We report the association of a cutaneous lesion with multiple endocrine neoplasia type 2A (MEN 2A) in three patients from a French family. These lesions are very similar to those previously described in an Italian and an American MEN 2A family and called cutaneous lichen amyloidosis. In all three families the patients presented with a pruritic and pigmented cutaneous lesion localized unilaterally on the upper back. However, in the French family the patients also complained of paroxysmal pain in the same area, in which we could elicit a touch hypoesthesia and pain hyperesthesia. Such an association of cutaneous and neurological features in the upper back is known as Notalgia Paresthetica (NP). NP is believed to represent a neuropathy of the posterior dorsal nerve rami. Unlike the two previously reported families, the histological, immunohistochemical and ultrastructural analysis of the skin biopsies of the French patients did not show any amyloid material. This suggests that the presence of amyloid may not be a constant feature of the cutaneous lesions associated with MEN 2A. We consider these lesions as a form of dorsal neuropathy rather than a cutaneous lichen amyloidosis. Whatever their origin, these cutaneous lesion usually precede the appearance of the neoplastic lesions of MEN 2A. They may act as an early clinical marker that must be searched for in each subject at risk for MEN 2A. In addition, all patients presenting with NP should be screened for MEN 2A. PMID:1348355

Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the

    Full Text Available Cytodiagnosis of cutaneous metastasis of renal cell carcinoma (RCC in the absence of history of primary tumor is difficult as it can be confused with other clear cell tumors. We report here a case of cytodiagnosis of cutaneous metastasis of RCC in a patient who had nephrectomy done 9 years back at some other centre, but did not have any records with him. Clinicians should be aware of the possibility of primary internal organ malignancy in patients presenting with cutaneous lesions and therefore conduct a careful examination and get necessary investigations. Prompt diagnosis and treatment will have its bearing on the eventual outcome.
