Full Text Available We report a case of histologically confirmed primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT that subsequently underwent spontaneous regression in the absence of systemic treatment. The case showed an atypical lymphoid infiltrate that was CD20+ and MUM-1+ and CD10–. A subsequent biopsy of the spontaneously regressed lesion showed fibrosis associated with a lymphocytic infiltrate comprising reactive T cells. PCDLBCL-LT is a cutaneous B-cell lymphoma with a poor prognosis, which is usually treated with chemotherapy. We describe a case of clinical and histologic spontaneous regression in a patient with PCDLBCL-LT who had a negative systemic workup but a recurrence over a year after his initial presentation. Key words: B cell, lymphoma, primary cutaneous diffuse large B-cell lymphoma, leg type, regression

The dimorphic fungus Sporothrix schenckii commonly causes localized cutaneous disease with lymphocutaneous distribution. However, disseminated sporotrichosis occurs predominantly in immunocompromised patients. We report a case of disseminated cutaneous sporotrichosis in a patient with newly diagnosed HIV with a CD4 count of 208. The patient presented with multiple cutaneous and subcutaneous nodules as well as fever and malaise. Tissue culture and skin biopsy confirmed the diagnosis of sporotrichosis. He was started on itraconazole 200mg twice a day with rapid resolution of fever along with cessation of the development of new lesions.

Vasculitis represents a specific pattern of inflammation of the blood vessel wall that can occur in any organ system of the body. The neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are currently used as markers of inflammation in several diseases. This study analyzed C-reactive protein level (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC), NLR, and RDW in patients who had cutaneous vasculitis, or cutaneous vasculitis with systemic involvement, and in healthy controls. A total of 85 individuals were included in our study: 45 with vasculitis and 40 healthy controls. Patients who had complete blood count (CBC) analysis, CRP, and ESR at the time of skin biopsy were included in the study. NLR was calculated from these parameters. NLR, CRP, ESR, and WBC were significantly higher in patients with vasculitis than in healthy controls (p≤0.05), but RDW did not significantly differ between the two groups. This study suggests that blood NLR may be used for predicting vasculitis, especially cutaneous vasculitis with systemic involvement. © 2017 by the Association of Clinical Scientists, Inc.

Reactivation of latent herpes simplex virus infection by ultraviolet light: a human model

International Nuclear Information System (INIS)

Perna, J.J.; Mannix, M.L.; Rooney, J.F.; Notkins, A.L.; Straus, S.E.

Infection with herpes simplex virus often results in a latent infection of local sensory ganglia and a disease characterized by periodic viral reactivation and mucocutaneous lesions. The factors that trigger reactivation in humans are still poorly defined. In our study, five patients with documented histories of recurrent herpes simplex virus infection on the buttocks or sacrum were exposed to three times their minimal erythema dose of ultraviolet light. Site-specific cutaneous herpes simplex virus infection occurred at 4.4 +/- 0.4 days after exposure to ultraviolet light in 8 of 13 attempts at reactivation. We conclude that ultraviolet light can reactivate herpes simplex virus under experimentally defined conditions. This model in humans should prove useful in evaluating the pathophysiology and prevention of viral reactivation

The treatment of cutaneous lupus erythematosus is centered upon formulating a regimen of topical and systemic therapies designed to reduce disease activity and minimize cosmetic damage. Sun avoidance and sunscreen are important preventative measures proven to minimize cutaneous lupus erythematosus exacerbations. Limited disease is typically managed with topical corticosteroids or calcineurin inhibitors. Antimalarial therapy is the gold standard of systemic therapy. Many other treatments have been studied in patients with recalcitrant cutaneous lupus erythematosus, and their use must be evaluated based on individual risk-benefit concerns. R-salbutamol and pulsed dye laser therapy have proven to be effective topical alternatives. Additional systemic agents include retinoids, immunosuppressants, immunomodulators, biologics, and other experimental therapies with novel modes of action. According to the Oxford Centre for Evidence-based Medicine criteria for evaluating the strength of evidence supporting an individual treatment measure, no therapy for cutaneous lupus erythematosus has achieved Level 1 status. This demonstrates the need for randomized, controlled trials and systematic reviews of all cutaneous lupus erythematosus interventions in order to meet increasing standards and demand for evidence-based practice.

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

Cutaneous Manifestations of Human and Murine Leishmaniasis

Directory of Open Access Journals (Sweden)

Breanna M. Scorza

2017-06-01

Full Text Available The leishmaniases are diseases caused by pathogenic protozoan parasites of the genus Leishmania. Infections are initiated when a sand fly vector inoculates Leishmania parasites into the skin of a mammalian host. Leishmania causes a spectrum of inflammatory cutaneous disease manifestations. The type of cutaneous pathology is determined in part by the infecting Leishmania species, but also by a combination of inflammatory and anti-inflammatory host immune response factors resulting in different clinical outcomes. This review discusses the distinct cutaneous syndromes described in humans, and current knowledge of the inflammatory responses associated with divergent cutaneous pathologic responses to different Leishmania species. The contribution of key hematopoietic cells in experimental cutaneous leishmaniasis in mouse models are also reviewed and compared with those observed during human infection. We hypothesize that local skin events influence the ensuing adaptive immune response to Leishmania spp. infections, and that the balance between inflammatory and regulatory factors induced by infection are critical for determining cutaneous pathology and outcome of infection.

Full Text Available Cutaneous metastases from primary internal malignancies are an uncommon presentation. Cutaneous metastases are more frequently seen in breast cancer than in any other visceral malignancy in women. Medical practitioners should be vigilant of the possibility of unusual presentations of metastatic disease in breast cancer patients with lobular carcinoma presenting as cutaneous lesions mimicking benign dermatological conditions. Herein, we present a case of a 75-year-old woman presenting with cutaneous lobular breast carcinoma metastases on her anterior right leg, which had previously been misdiagnosed as dermatitis for 9 years.

Photochemistry and photobiology of actinic erythema: defensive and reparative cutaneous mechanisms

Full Text Available Sunlight is part of our everyday life and most people accept it as beneficial to our health. With the advance of our knowledge in cutaneous photochemistry, photobiology and photomedicine over the past four decades, the terrestrial solar radiation has become a concern of dermatologists and is considered to be a major damaging environmental factor for our skin. Most photobiological effects (e.g., sunburn, suntanning, local and systemic immunosuppression, photoaging or dermatoheliosis, skin cancer and precancer, etc. are attributed to ultraviolet radiation (UVR and more particularly to UVB radiation (290-320 nm. UVA radiation (320-400 nm also plays an important role in the induction of erythema by the photosensitized generation of reactive oxygen species (singlet oxygen (1O2, superoxide (O2.- and hydroxyl radicals (.OH that damage DNA and cellular membranes, and promote carcinogenesis and the changes associated with photoaging. Therefore, research efforts have been directed at a better photochemical and photobiological understanding of the so-called sunburn reaction, actinic or solar erythema. To survive the insults of actinic damage, the skin appears to have different intrinsic defensive mechanisms, among which antioxidants (enzymatic and non-enzymatic systems play a pivotal role. In this paper, we will review the basic aspects of the action of UVR on the skin: a photochemical reactions resulting from photon absorption by endogenous chromophores; b the lipid peroxidation phenomenon, and c intrinsic defensive cutaneous mechanisms (antioxidant systems. The last section will cover the inflammatory response including mediator release after cutaneous UVR exposure and adhesion molecule expression

American cutaneous leishmaniasis triggered byelectrocoagulation

Directory of Open Access Journals (Sweden)

Sofia Sales Martins

Full Text Available Abstract Cutaneous leishmaniasis is usually transmitted by infected phlebotomine sand fly bites that initiate local cutaneous lesions. Few reports in the literature describe other modes of transmission. We report a case of a previously healthy 59-year-old woman who underwent electrocoagulation to remove seborrheic keratosis confirmed by dermatoscopy. Three months later, a skin fragment tested positive for Leishmania culture; the parasite was identified as L. (V. braziliensis. Trauma may generate inflammatory cascades that favor Leishmania growth and lesion formation in previously infected patients. American cutaneous leishmaniasis is a dynamic disease with unclear pathophysiology because of continually changing environments, demographics, and human behaviors.

Sporotrichosis is the most prevalent subcutaneous mycosis and is characterized by a subacute or chronic development of a cutaneous or subcutaneous nodular lesion. It is caused by the dimorphic fungus Sporothrix spp, which may manifest in different clinical forms. The disseminated cutaneous form is uncommon and is more likely to occur in immunocompromised patients. We report a 47-year-old male patient with multiple cutaneous and subcutaneous nodules. The patient was diagnosed with disseminated cutaneous sporotrichosis based on the isolation and identification of Sporothrix spp. The patient was treated with potassium iodide, which resulted in clinical improvement of the lesions.

The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force...... of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle...... joint.

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)

Cutaneous lichen planus: A systematic review of treatments.

Science.gov (United States)

Fazel, Nasim

2015-06-01

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

Laser therapy for cutaneous sarcoidosis: A review

Directory of Open Access Journals (Sweden)

Teo Soleymani

2016-03-01

Full Text Available Sarcoidosis is a systemic, multi-organ disease of unknown etiology characteristically defined by the development of non-caseating granulomas. The development of sarcoidosis has been associated with a number of environmental and microbacterial factors coupled with genetic susceptibility. Depending on the type, location and distribution of disease, sarcoidosis can cause functional impairment, symptomatic distress, scarring and disfigurement. The advent of lasers as precise, minimally destructive surgical tools has allowed for their development as promising alternatives that minimize the morbidity associated with current therapies.In this paper, we reviewed the role of laser therapy in the treatment of cutaneous sarcoidosis. A comprehensive search of the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literatures investigating the role of laser therapy in the treatment of cutaneous sarcoidosis. In our opinion, laser therapy, particularly PDL, appears to be an effective, safe and generally well-tolerated modality for the treatment of cutaneous sarcoidosis and should be considered in patients with localized cutaneous disease that is refractory to conventional treatments. Less is known about the efficacy and tolerability of ablative laser therapy for the treatment of cutaneous sarcoidosis, though the limited data appears promising as well. With that said, however, the data is limited and warrants a need for additional larger, randomized controlled studies to further investigate the utility and efficacy of laser therapy in the treatment of cutaneous sarcoidosis.

Adverse Cutaneous Reactions to Psychotropic Drugs: A Review

Directory of Open Access Journals (Sweden)

Filipa Novais

2015-11-01

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

Comparing the characteristics of highly cited titles and highly alted titles

2016-07-01

This study examines differences in the types of titles for articles that show high altmetric activity (highly alted articles) versus highly cited articles. This work expands on previous research on document titles in combination with a grounded theory approach to develop a codebook in which articles were manually coded based on 11 characteristics. The results show that there are differences and similarities in titles across many of the examined characteristics; highly cited titles and highly mentioned titles on Wikipedia have some similar characteristics such as they have the the highest percentage of substantive words; in addition, there are no or very few titles referencing outside or with humor/lightness on both platforms. Twitter and Facebook also showed some similarities having the highest percentage of humorous/light titles and lowest percentage of substantive words in their titles. (Author)

José Moreira

2016-11-01

Full Text Available Angionvasive mucormycosis is an emerging fungal disease known to affect mainly diabetics or subjects with profound neutropenia. Infection usually occurs through the inhalation route, but cutaneous inoculation may occur after trauma or burns. However, mucormycosis remains unusual in HIV infection. We report a fatal case of cutaneous mucormycosis due to Rhizopus arrhizus involving the scalp following herpes zoster infection. The patient was a 42-year-old man with advanced AIDS failing on salvage antiretroviral therapy. The fungus was diagnosed on the basis of histopathology and culture. Our case emphasizes the need to consider mucormycosis in the differential diagnosis of necrotic cutaneous lesions in patients with late-stage HIV disease.

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

Full Text Available Eccrine syringofibroadenoma (ESFA is an uncommon benign adnexal neoplasm which derives from cells of the acrosyringium of eccrine sweat glands. The clinical appearance is nonspecific but the histological features are typical. Five clinical subtypes of ESFA exist: (1 solitary ESFA; (2 multiple ESFA associated with ectodermal dysplasia; (3 multiple ESFA without cutaneous features; (4 unilateral linear ESFA (nevoid, and (5 reactive ESFA associated with inflammatory or neoplastic dermatoses. We report the case of a 42-year-old man with long-standing diabetes and neuropathy, presenting with a 4-year history of asymptomatic erythematous plaques on a background of brown hyperpigmentation on the left foot. The clinical presentation and histopathological findings are compatible with reactive ESFA.

Acitretin for the management of generalized cutaneous lichen planus.

Science.gov (United States)

Vazirnia, Aria; Cohen, Philip R

2014-09-16

Lichen planus is an inflammatory disease that affects the skin, the oral mucosa, or both. Generalized cutaneous lichen planus may pose a therapeutic challenge for clinicians if the condition persists or flares after topical or systemic corticosteroid therapy. Acitretin, a systemic retinoid, can be considered a potential second-line treatment for patients with generalized cutaneous lichen planus. Herein, we describe a postmenopausal woman with generalized cutaneous lichen planus who was successfully treated with acitretin. A 58-year-old woman presented with generalized cutaneous lichen planus involving her upper and lower extremities as well as her lower back. After failing corticosteroid therapy, she was started on acitretin 20 mg/day, which was later increased to 30 mg/day. To review the literature on the use of acitretin in cutaneous lichen planus, we used the PubMed search engine and searched for the terms "acitretin" and "cutaneous lichen planus." Our patient had complete resolution of pruritus within one week of initiating acitretin 20 mg/day. After an increase in dose to 30 mg/day, the cutaneous lesions completely resolved over a 3-month period. There was no recurrence of disease as acitretin was tapered and discontinued. Generalized cutaneous lichen planus may pose a therapeutic challenge for the symptomatic relief of skin lesions. Topical and systemic corticosteroids are first-line treatments. In patients who fail corticosteroids, relapse after corticosteroid therapy, or have contraindications to corticosteroids, acitretin may be considered a potential second-line therapy.

A detailed interpretation of the FT-IR and FT-Raman spectra has been performed on the basis of the observed and calculated infrared and Raman spectra as well as calculated potential energy distribution values. Comparison of Raman and SERS spectra suggests a tilted orientation of the rings on the metal surface. The dipole moment, polarizability and first and second order hyperpolarizability values of the molecule were calculated. Global reactivity parameters were predicted. The relative reactivities towards electrophilic and nucleophilic attack are predicted using molecular electrostatic potential map. Average local ionization energy (ALIE) and Fukui functions have been inspected in order to investigate local reactivity properties of title molecule. The importance of autoxidation and hydrolysis mechanisms for the title molecule has been assessed by DFT calculations of bond dissociation energies (BDE) and by calculations of radial distribution functions (RDFs) after molecular dynamics (MD) simulations. Molecular docking studies suggest that the title compound can be a lead compound for developing new anti-cancerous drug.

Accidental exposure to ionising radiation may occur during such catastrophic events as the Chernobyl accident in 1986 or for days and weeks as in Goiania in 1987 and in the military camp during the training of soldiers in Lilo/Georgia in 1997 as well as in medical institutions. The cutaneous symptoms after radiation exposure are based on a combination of inflammatory processes and alteration of cellular proliferation as a result of a specific pattern of transcriptionally activated pro-inflammatory cytokines and growth factors. They follow a time course consisting of prodromal erythema, manifestation, chronic stage, late stage and they are referred to as Cutaneous Radiation Syndrome. The time course depends on several factors such as the applied radiation dose, radiation quality, individual radiation sensitivity, the extent of contamination and absorption and volume of the skin. For diagnostics of the cutaneous radiation syndrome the following procedures are used: 7.5 MHz to 20 MHz-B-scan-sonography, thermography, capillary microscopy, profilometry, nuclear magnetic resonance imaging, bone scintigraphy and histology. Based on the results of experimental and clinical research of the last years pharmacotherapy of the cutaneous radiation syndrome includes topic or systemic application of corticosteroids, gamma-interferon, pentoxifylline and vitamin E and superoxide dismutase. The treatment depends on the stage of the cutaneous radiation syndrome. Due to the complexity of the clinical manifestations of radiation disease in most patients an interdisciplinary treatment in specialized centres is necessary. Dermatologists are asked to perform in most cases life-long therapy and follow-up of the patients. (author)

The cutaneous innervation of the thoracic limb was investigated in 36 barbiturate-anesthetized dogs, using electrophysiologic techniques. The cutaneous area (CA) innervated by each cutaneous nerve was delineated in at least five dogs by stroking the hair in the area with a small watercolor brush while recording from the nerve. Mapping of adjacent CA revealed areas of considerable overlapping. The part of the CA of a given nerve supplied by only that nerve is referred to as its autonomous zone. Of all nerves arising from the brachial plexus, only the suprascapular, subscapular, lateral thoracic, thoracodorsal, and cranial and caudal pectoral nerves lacked cutaneous afferents. The dorsal cutaneous branch of C6 had a CA, but no grossly demonstrable dorsal cutaneous branches for C7 C8, or T1 were found. The cervical nerves had ventral cutaneous branches, but no lateral cutaneous branches. Thoracic nerves T2-T4 had dorsal, ventral, and lateral cutaneous branches. The cutaneous branches of the brachiocephalic, axillary, musculocutaneous, radial, median, and ulnar nerves all had CA which were overlapped by adjacent CA, thus their autonomous zones were much smaller than the cutaneous areas usually depicted for these nerves in anatomy and neurology textbooks.

Cutaneous mucormycosis in advanced HIV disease.

Moreira, José; Ridolfi, Felipe; Almeida-Paes, Rodrigo; Varon, Andrea; Lamas, Cristiane C

Angionvasive mucormycosis is an emerging fungal disease known to affect mainly diabetics or subjects with profound neutropenia. Infection usually occurs through the inhalation route, but cutaneous inoculation may occur after trauma or burns. However, mucormycosis remains unusual in HIV infection. We report a fatal case of cutaneous mucormycosis due to Rhizopus arrhizus involving the scalp following herpes zoster infection. The patient was a 42-year-old man with advanced AIDS failing on salvage antiretroviral therapy. The fungus was diagnosed on the basis of histopathology and culture. Our case emphasizes the need to consider mucormycosis in the differential diagnosis of necrotic cutaneous lesions in patients with late-stage HIV disease.

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

Cutaneous allergic reactions to Triatoma infestans after xenodiagnosis Reações cutâneas alérgicas ao Triatoma infestans após Xenodiagnóstico

Full Text Available We determined the frequency of cutaneous allergic reactions to bites of Triatoma infestans during xenodiagnosis in a rural community where Panstrongylus megistrus is the only domestic vector of Trypanosoma cruzi. Localized urticaria or more intense cutaneous allergic reactions at 48 and 72 hours were observed in 86.7% and 82.1% respectively of the individuals in our study. Urticaria was more severe in children and older adults and in women than in men. The high frequency of reactions suggests either cutaneous reactivity to T. infestans without prior sensitization or cross reactivity between P. megistus and T. infestans. A single application of topical corticosteroid or antihistamine medication did not reduce the cutaneous reactions.A freqüência de reações cutâneas alérgicas ás picadas de Triatoma infestans após xenodiagnóstico foi determinada numa comunidade rural na qual Panstrongylus megistus é o único vetor doméstico. Urticária focal ou reações cutâneas alérgicas mais intensas foram observadas em 86.7% e em 82.1% dos participantes estudados, respectivamente ás 48 e ás 72 horas. A urticária foi mais severa em crianças e adultos idosos e mais severa em mulheres do que em homens. A alta freqüência das reações sugere a existência de reatividade cutânea ao T. infestans, sem prévia sensibilização, ou uma reatividade cruzada entre P. megistus e T. infestans. A aplicação tópica de pomada de corticosteróide ou de anti-histamínico não reduziu as reações cutâneas alérgicas.

2010-01-01

Cutaneous lung tissue heterotopia is a very rare disorder where mature lung tissues develop in the skin. This is only the second known report of cutaneous lung tissue heterotopia, with the first by Singer et al. in 1998. A newborn infant had a hemangioma-like, freely movable mass connected to the anterior aspect of the sternal manubrium. Pathologic findings showed mature lung tissues with bronchi, bronchioles, and alveoli through the dermis and subcutis, and it was diagnosed as cutaneous lung tissue heterotopia. Cutaneous lung tissue heterotopia is hypervascular, so grossly it looks like a hemangioma. It can be differentiated from pulmonary sequestration, teratoma, bronchogenic cyst, and branchial cleft cyst by histology and the location of the mass. We describe the clinical, radiologic, and pathologic findings of a cutaneous lung tissue heterotopia, the first reported in Korea. PMID:20808688

Full Text Available Radial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.

2010-07-01

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

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)

To evaluate the efficacy of the effects of heat-killed Lactobacillus brevis SBC8803 (HK-SBC8803) on the standard physiological markers of skin health of cutaneous arterial sympathetic nerve activity (CASNA), cutaneous blood flow and transepidermal water loss (TEWL) and to determine whether SBC8803 targets serotonin 5-HT3 receptors in rats. A set of three experiments were conducted to examine the effects of SBC8803 on CASNA, cutaneous blood flow and TEWL using Wistar and hairless rats. Two additional experiments further attempted to determine whether HK-SBC8803 was targeting the serotonin 5-HT3 receptors by pretreatment with the 5-HT3 antagonist granisetron. Administration of HK-SBC8803 in the first three experiments caused marked inhibition of CASNA and significant elevation of cutaneous blood flow under urethane anaesthesia as well as significant decrease in TEWL on the dorsal skin of conscious hairless rats. Pretreatment with granisetron decreased the effects of HK-SBC8803 on CASNA and cutaneous blood flow. These findings suggest that HK-SBC8803 reduces CASNA, increases cutaneous blood flow and decreases TEWL and that 5-HT3 receptors may be involved in CASNA and cutaneous blood flow responses. HK-SBC8803 could be a useful substance in the treatment/prevention of skin problems, specifically chapped or dry skin. © 2014 The Society for Applied Microbiology.

Conjunctival reactive epithelial hyperplasia in a black African patient– a case report

Adedolapo Olaopa

2018-05-01

Full Text Available Reactive hyperplasia can occur in any part of the body but of concern is occurrence adjacent to certain neoplasm such as cutaneous fibrous histiocytoma, granular cell tumor, spitz nevus and melanoma. Ocular reactive epithelial hyperplasia is not as common as ocular reactive lymphoid hyperplasia. This is the first reported case in our environment. The patient was concerned about his cosmetic appearance, comments of friends and fear of eye problem in future. We report the case of a 32 year old patient with painless, progressive swelling of the conjunctiva following stone injury to the eye while on a bike 5 years earlier. A traumatic conjunctival cyst to rule out melanoma was the initial diagnosis. We therefore, managed the case by excision biopsy and histology report was in keeping with conjunctival reactive epithelial hyperplasia. One year after removal, he was free of any swelling and had no complaints. Conclusion: Excision biopsy is effective and it will assist in ruling out neoplasm and taking care of the patient’s cosmetic problem.

Multiple Cutaneous Metastases as Initial Presentation in Advanced Colon Cancer

Sudheer Nambiar

2018-01-01

Full Text Available Skin metastases from advanced colorectal cancer are relatively rare and occur most often when the cancer is advanced, following the spread to other organs. Cutaneous metastases occur in about 3% of advanced colorectal cancers. We present an extremely rare case of a 68-year-old woman with advanced ascending colon adenocarcinoma that presented with multiple rapidly progressing painless cutaneous metastatic lesions with no other distant metastases. Of all the tumors, breast cancer most commonly spreads as cutaneous metastasis is followed by lung, colorectal, renal, ovarian, and bladder cancers. Cutaneous metastases can present in a variety of clinical manifestations, such as a rapidly growing painless dermal or subcutaneous nodule with intact overlying epidermis or as ulcers. In cases where the cutaneous deposit is isolated, as in visceral metastasis, there is a role for radical management such as wide local excision and reconstruction. In our patient, since she had multiple cutaneous metastases she began treatment with palliative systemic combination chemotherapy.

Hydroxyurea is a medication with many well-described cutaneous side effects, notably the dermatomyositis-like eruption known as hydroxyurea dermopathy. Although systemic lupus erythematosus has been reported with hydroxyurea use, cutaneous lupus has not. We report a novel case of chronic cutaneous lupus induced by hydroxyurea and propose that this is a side effect that is distinct from hydroxyurea dermopathy. © 2016 Wiley Periodicals, Inc.

2015-01-01

Sarcoidosis is a multi-system granulomatous disease of unknown etiology. The skin is involved in 25% of cases. Studies on cutaneous sarcoidosis from our region are lacking. This study was conducted to describe clinical and histopathologic findings in all patients diagnosed with cutaneous sarcoidosis at the American University of Beirut Medical Center between 1992 and 2010 and to compare findings with those published in the literature. Clinical charts of patients with cutaneous sarcoidosis were retrospectively reviewed. Extracutaneous lesions were classified by organ involvement. Treatment was documented. Pathology specimens were reviewed. Cutaneous sarcoidosis was diagnosed in 76 Lebanese patients, 79% of whom were women. Mean age at diagnosis was 48 years. A total of 29% of patients had systemic disease that was commonly associated with lupus pernio lesions and subcutaneous sarcoidosis. The most common cutaneous lesions were sarcoidal plaques. The histopathologic features in our series did not differ from those described in the literature, except for the documented presence of a grenz zone. Interestingly, 23% of biopsy specimens contained perineural granulomas, raising the possibility of tuberculoid or borderline tuberculoid leprosy. Foreign bodies were detected in 10% of cases (all had systemic involvement), supporting the opinion that sarcoidosis and granulomatous foreign body reaction are not mutually exclusive. The clinical and histopathologic features of cutaneous sarcoidosis patients in the present series are generally comparable with those published in the literature, with minor differences. Clinically, the most commonly seen lesion was plaque. Microscopically, cutaneous sarcoidosis may exhibit a grenz zone and may show perineural inflammation and foreign bodies. © 2014 The International Society of Dermatology.

Cutaneous sarcoidosis: A rare case report

Bindu Suparna M, Joshi Shivani

2014-07-01

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.

Fluid replacement modulates oxidative stress- but not nitric oxide-mediated cutaneous vasodilation and sweating during prolonged exercise in the heat.

McNeely, Brendan D; Meade, Robert D; Fujii, Naoto; Seely, Andrew J E; Sigal, Ronald J; Kenny, Glen P

2017-12-01

The roles of nitric oxide synthase (NOS), reactive oxygen species (ROS), and angiotensin II type 1 receptor (AT 1 R) activation in regulating cutaneous vasodilation and sweating during prolonged (≥60 min) exercise are currently unclear. Moreover, it remains to be determined whether fluid replacement (FR) modulates the above thermoeffector responses. To investigate, 11 young men completed 90 min of continuous moderate intensity (46% V̇o 2peak ) cycling performed at a fixed rate of metabolic heat production of 600 W (No FR condition). On a separate day, participants completed a second session of the same protocol while receiving FR to offset sweat losses (FR condition). Cutaneous vascular conductance (CVC) and local sweat rate (LSR) were measured at four intradermal microdialysis forearm sites perfused with: 1 ) lactated Ringer (Control); 2 ) 10 mM N G -nitro-l-arginine methyl ester (l-NAME, NOS inhibition); 3 ) 10 mM ascorbate (nonselective antioxidant); or 4 ) 4.34 nM losartan (AT 1 R inhibition). Relative to Control (71% CVC max at both time points), CVC with ascorbate (80% and 83% CVC max ) was elevated at 60 and 90 min of exercise during FR (both P 0.31). In both conditions, CVC was reduced at end exercise with l-NAME (60% CVC max ; both P 0.19). LSR did not differ between sites in either condition (all P > 0.10). We conclude that NOS regulates cutaneous vasodilation, but not sweating, irrespective of FR, and that ROS influence cutaneous vasodilation during prolonged exercise with FR.

Aplasia cutis congenita and cutaneous meningeal heterotopia are both rare congenital conditions that most commonly occur on the scalp and may appear clinically and histologically similar. A subtype of aplasia cutis congenita, membranous aplasia cutis congenita, and cutaneous meningeal heterotopia are both proposed to result from neural tube closure errors. However, neither non-membranous nor membranous aplasia cutis congenita are known to occur together with cutaneous meningeal heterotopia in the same lesion. We report the incidental finding of cutaneous meningeal heterotopia within a lesion of aplasia cutis congenita. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Subacute cutaneous lupus erythematosus presenting as poikiloderma.

LENUS (Irish Health Repository)

Hughes, R

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.

Modern radiation therapy for primary cutaneous lymphomas

Primary cutaneous lymphomas are a heterogeneous group of diseases. They often remain localized, and they generally have a more indolent course and a better prognosis than lymphomas in other locations. They are highly radiosensitive, and radiation therapy is an important part of the treatment......, either as the sole treatment or as part of a multimodality approach. Radiation therapy of primary cutaneous lymphomas requires the use of special techniques that form the focus of these guidelines. The International Lymphoma Radiation Oncology Group has developed these guidelines after multinational...... meetings and analysis of available evidence.

HTLV-1 is a virus that is endemic in southwesternJapan and the Caribbean and has been implicatedin the development of ATLL. ATLL, which is anuncommon malignant condition of peripheralT-lymphocytes, is characterized by four clinicalsubtypes, which include acute, lymphomatous,chronic, and smoldering types, that are based onLDH levels, calcium levels, and extent of organinvolvement. We present a 52-year- old woman withpruritic patches with scale on the buttocks and withtender, hyperpigmented macules and papules oftwo-years duration. Histopathologic examinationwas suggestive of mycosis fungoides, laboratoryresults showed HTLV-I and II, and the patient wasdiagnosed with primary cutaneous ATLL. We reviewthe literature on HTLV-1 and ATLL and specifically theprognosis of cutaneous ATLL. The literature suggeststhat a diagnosis of ATLL should be considered amongpatients of Caribbean origin or other endemicareas with skin lesions that suggest a cutaneousT-cell lymphoma, with clinicopathologic features ofmycosis fungoides. Differentiation between ATLLand cutaneous T-cell lymphoma is imperative as theyhave different prognoses and treatment approaches.

The cutaneous radiation syndrome: diagnosis and treatment

International Nuclear Information System (INIS)

Peter, R.U.; Steinert, M.; Gottlober, P.

2001-01-01

Accidental exposure to ionising radiation may occur during such catastrophic events as the Chernobyl accident in 1986 or for days and weeks as in Goiania in 1987 and in the military camp during the training of soldiers in Lilo/Georgia in 1997 as well as in medical institutions. The cutaneous symptoms after radiation exposure are based on a combination of inflammatory processes and alteration of cellular proliferation as a result of a specific pattern of transcriptionally activated pro-inflammatory cytokines and growth factors. They follow a time course consisting of prodromal erythema, manifestation, chronic stage, late stage and they are referred to as Cutaneous Radiation Syndrome. The time course depends on several factors such as the applied radiation dose, radiation quality, individual radiation sensitivity, the extent of contamination and absorption and volume of the skin. For diagnostics of the cutaneous radiation syndrome the following procedures are used: 7.5 MHz to 20 MHz-B-scan-sonography, thermography, capillary microscopy, profilometry, nuclear magnetic resonance imaging, bone scintigraphy and histology. Based on the results of experimental and clinical research of the last years pharmacotherapy of the cutaneous radiation syndrome includes topic or systemic application of corticosteroids, gamma-interferon, pentoxifylline and vitamin E and superoxide dismutase. The treatment depends on the stage of the cutaneous radiation syndrome. Due to the complexity of the clinical manifestations of radiation disease in most patients an interdisciplinary treatment in specialized centres is necessary. Dermatologists are asked to perform in most cases life-long therapy and follow-up of the patients. (author)

2012-01-01

Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease of unknown etiology with many clinical manifestations. The skin is one of the target organs most variably affected by the disease. The American College of Rheumatology (ACR) established 11 criteria as a classificatory instrument to operationalise the definition of SLE in clinical trials. They were not intended to be used to diagnose individuals and do not do well in that capacity. Cutaneous lesions account for four of these 11 revised criteria of SLE. Skin lesions in patients with lupus may be specific or nonspecific. This paper covers the SLE-specific cutaneous changes: malar rash, discoid rash, photosensitivity, and oral mucosal lesions as well as SLE nonspecific skin manifestations, their pathophysiology, and management. A deeper thorough understanding of the cutaneous manifestations of SLE is essential for diagnosis, prognosis, and efficient management. Thus, dermatologists should cooperate with other specialties to provide optimal care of SLE patient. PMID:22888407

Ampullary carcinoma with cutaneous metastasis

2016-06-01

Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

Cutaneous tuberculosis as a result of a needle injection is a rare event; it generally occurs among medical and laboratory personnel and among patients receiving percutaneous treatment. Six patients are presented who developed cutaneous tuberculosis after mesotherapy cosmetic treatment. One to four months after injection of an unknown product as treatment for obesity and cellulites, five women and a man developed papules, nodules and drainage of wax like material at the inoculated sites; this was interpreted clinically as a non tuberculous mycobacterium infection. Skin biopsies were taken for a histopathologic study; the biopsy and exudates were cultured to make a phenotypic identification. Polymerase chain reaction and restriction enzyme pattern analyses (PCR-restriction pattern analysis)) procedures were applied to the skin biopsies. Mycobacterium tuberculosis was confirmed in the culture and by PRA analysis in the paraffin-embedded biopsies. The patients had never had tuberculosis. Their thoracic X rays were normal and the size of the tuberculin reaction was 17 to 20 mm. Five patients recovered with antituberculosis treatment and the sixth spontaneously healed after the removal of the largest cutaneous module. No satellite adenopathy or recurrences were observed. A previously undescribed mode of acquisition cutaneous tuberculosis was described. This was the second incident of a demonstrated cutaneous tuberculosis following mesotherapy in Colombia. Skin lesions induced by injections must be tested to detect mycobacterias to include M. tuberculosis.

Khaled, A; Sassi, S; Fazaa, B; Ben Hassouna, J; Ben Romdhane, K; Kamoun, M R

2009-02-01

According to the WHO-EORTC classification of cutaneous lymphomas, primary cutaneous marginal zone B-cell lymphoma are now well characterized. We report here a case of primary cutaneous marginal zone B-cell lymphoma in a 51 year-old man in which the diagnosis was made using both histology and immunopathology. The patient had no remarkable medical history, no history of either acute inflammation or insect bite, and presented with a 5 cm solitary asymptomatic erythematous firm, multinodular and infiltrated plaque on the back for 12 months. Histological examination and immunohistochemical study of a cutaneous biopsy provided a differential diagnosis between B cell lymphoma and lymphocytoma cutis. Full body work up revealed no signs of extracutaneous dissemination. The patient underwent surgical excision of the nodule. Histological examination showed a histological and immunophenotyping profile typical of primary cutaneous marginal zone B-cell lymphoma. The lesion was completely excised with clear margins and no recurrence occurred after a 12 month-follow-up period. Primary cutaneous marginal zone B-cell lymphoma are low-grade lymphomas that have an indolent course and a high tendency to recur. They should be differentiated from lymphocytoma cutis and from the other types of cutaneous B cell lymphomas that have a different course and prognosis.

The skin is a common target of small vessel vasculitis, with a wide assortment of pathological changes. This condition is usually associated to systemic diseases. To report the clinical and pathological features of patients with cutaneous small vessel vasculitis. A retrospective review of 32 patients with a pathological diagnosis of cutaneous vasculitis. Seventy two percent of patients were women. Cutaneous lesions were mainly located in the lower limbs (94%). The most common lesion was palpable purpura (62%). Connective tissue diseases and systemic vasculitis were the most commonly associated systemic diseases. Palpable purpura is the most common manifestation of cutaneous small vessel vasculitis, that is usually associated to connective tissue diseases or systemic vasculitis.

2018-02-07

Systemic therapies for metastatic cutaneous melanoma, the most aggressive of all skin cancers, remain disappointing. Few lasting remissions are achieved and the therapeutic aim remains one of palliation.Many agents are used alone or in combination with varying degrees of toxicity and cost. It is unclear whether evidence exists to support these complex regimens over best supportive care / placebo. To review the benefits from the use of systemic therapies in metastatic cutaneous melanoma compared to best supportive care/placebo, and to establish whether a 'standard' therapy exists which is superior to other treatments. Randomised controlled trials were identified from the MEDLINE, EMBASE and CCTR/CENTRAL databases. References, conference proceedings, and Science Citation Index/Scisearch were also used to locate trials. Cancer registries and trialists were also contacted. Randomised controlled trials of adults with histologically proven metastatic cutaneous melanoma in which systemic anti-cancer therapy was compared with placebo or supportive care. Study selection was performed by two independent reviewers. Data extraction forms were used for studies which appeared to meet the selection criteria and, where appropriate, full text articles were retrieved and reviewed independently. No randomised controlled trials were found comparing a systemic therapy with placebo or best supportive care in metastatic cutaneous melanoma. There is no evidence from randomised controlled clinical trials to show superiority of systemic therapy over best supportive care / placebo in the treatment of malignant cutaneous melanoma.Given that patients with metastatic melanoma frequently receive systemic therapy, it is our pragmatic view that a future systematic review could compare any systemic treatment, or combination of treatments, to single agent dacarbazine.

Cutaneous reaction associated with weekly docetaxel administration.

Science.gov (United States)

Chew, Lita; Chuen, Vivianne Shih Lee

2009-03-01

Docetaxel-based chemotherapy will remain clinically relevant and many of our patients will continue to receive the drug. In a recent phase 2 study of docetaxel 35 mg/m2 (weekly) in patients with metastatic breast cancer, the incidence of grade 3 cutaneous toxicity is 19%. The skin toxicity observed consists of limb/palmar-plantar erythematous reactions, or fixed-plaque erythrodysesthesia. Case series or reports have reported varied manifestations of skin reactions and include erythema multiforme, nail changes (onycholysis, pigmentation, paronychia), scleroderma, supravenous discoloration, radiation recall dermatitis, and flagellate erythema. We would like to report four patients with cutaneous reactions resulting from weekly administration of docetaxel. All cases are heavily pre-treated patients, receiving docetaxel as second or third line therapy. The cutaneous reactions occur at cycle 5. The time between chemotherapy to development of skin lesions is from 1 to 7 days. Lesions usually resolve with desquamation leaving behind areas with hyper-pigmentation or hypo-pigmentation over a period of 2 to 3 weeks. The management strategies include hand elevation, warm or cold compresses, topical and/or systemic antibiotics, topical and/or systemic corticosteroids, and cessation of drug. There is a need for a systematic approach to manage these cutaneous reactions. Oncology trained pharmacists play vital roles in assessing, managing, documenting and patient education.

2013-02-01

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

Stem Cells for Cutaneous Wound Healing.

Science.gov (United States)

Kirby, Giles T S; Mills, Stuart J; Cowin, Allison J; Smith, Louise E

2015-01-01

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.

2018-05-01

Malignant pleural mesothelioma is a rare neoplasm of mesodermal origin. Cutaneous involvement of malignant pleural mesothelioma is a very rare entity, with only 11 cases reported in the literature. Here, we describe the case of a 75-year-old man with stage IV epithelioid pleural mesothelioma, presenting with a cutaneous eruption 5 months after initial diagnosis, which revealed sarcomatoid features on skin biopsy. Histological analysis of malignancy progression through immunohistochemical staining of the pleural, lymph node, and skin tissue revealed gradual loss of calretinin and gain of desmin, supporting a transformation from epithelioid to sarcomatoid tissue. To our knowledge, this is the first reported case of an epithelioid to sarcomatoid transformation of malignant pleural mesothelioma manifesting in a cutaneous presentation.

Primary cutaneous lymphomas are uncommon. This article describes the Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV) and reports on the results from the first year. Disease registry for patients with primary cutaneous lymphoma. The participating hospitals prospectively recorded data on diagnosis, treatment, tests, and disease stage for all patients with primary cutaneous lymphoma. A descriptive analysis was performed. In December 2017, the registry contained data on 639 patients (60% male) from 16 university hospitals. The most common diagnoses, in order of frequency, were mycosis fungoides/Sézary syndrome (MF/SS) (348 cases, 55%), primary cutaneous B-cell lymphoma (CBCL) (184 cases, 29%), primary cutaneous CD30 + T-cell lymphoproliferative disorder (CD30 + CLPD) (70 cases, 11%), and other types of T-cell lymphoma (37 cases, 5%). In total, 105 (16.5%) of the cases recorded were incident cases. The most common diagnosis in the MF/SS group was classic MF (77.3%). Half of the patients with MF had stage IA disease when diagnosed, and the majority were either in partial remission (32.5%) or had stable disease (33.1%). The most widely used treatments were topical corticosteroids (90.8%) and phototherapy. The most common form of primary CBCL was marginal zone lymphoma (50%). Almost all of the patients had cutaneous involvement only and nearly half had stage T1a disease. Most (76.1%) were in complete remission. The main treatments were surgery (55.4%) and radiotherapy (41.9%). The most common diagnosis in patients with CD30 + CLPD was lymphomatoid papulosis (68.8%). Most of the patients (31.4%) had stage T3b disease and half were in complete remission. The most common treatments were topical corticosteroids (68.8%) and systemic chemotherapy (32.9%). The characteristics of patients with primary cutaneous lymphoma in Spain do not differ from those described in other series in the literature. The registry will facilitate

Diffuse Cutaneous Mastocytosis in a Child - a Case Report

Directory of Open Access Journals (Sweden)

Popadić Svetlana

2017-09-01

Full Text Available Mastocytosis refers to a group of diseases characterized by a clonal proliferation and accumulation of mast cells in one or more tissues/organs with different clinical presentations. In children, limited cutaneous forms of mastocytosis are rather frequent, while systemic mastocytosis is rare. The diagnosis of cutaneous mastocytosis is based on clinical findings and histopathology. We present a patient who developed skin lesions at the age of 18 months. Clinical findings, confirmed by histopathology, were consistent with diffuse cutaneous mastocytosis. The follow-up period was 7 years. The treatment included oral antihistamines in combination with mast cell stabilizers, mild topical steroids and avoidance of friction. During the follow-up period, there were no signs of systemic involvement, and the quality of life was preserved, despite the large surface of affected skin. This case report should increase the awareness and knowledge of clinicians about this rare form of cutaneous mastocytosis in the pediatric population.

Bronchopleural cutaneous fistula due to Eikenella corrodens.

Science.gov (United States)

Wong, Kin-Sun; Huang, Yhu-Chering

2005-01-01

The aim of this paper is to review the subject and to report on and discuss a case of bronchopleural cutaneous fistula due to Eikenella corrodens. A 16-year-old girl was brought to our hospital with fever and blood-tinged sputum 2 weeks prior to her admission. She suffered from neurologic sequelae of herpetic encephalitis and had been bed-ridden since 5 years of age. A longitudinal paraspinal soft mass had been noted in the previous week by her mother. She had been given oral feeding despite frequent choking for the past few years. On palpation, the mass can be squeezed to follow the least resistance of subcutaneous space longitudinally extending to the lower thoracic region. Chest computed tomography scan revealed right lower lobe necrotizing pneumonitis and a pleuro-cutaneous fistula leading to the subcutaneous air locules. A protracted course of antibiotics was prescribed and subcutaneous air trapping decreased in size over 8 weeks. Eikenella corrodens has increasingly been implicated as a potential causative pathogen in pleuropulmonary infections. Pleuro-cutaneous fistula and abscess formation complicating empyema and necrotizing pneumonitis due to E. corrodens infection have not been reported. A bulging thoracic subcutaneous lesion waxes and wanes with respiration suggest the possibility of a pleruo-cutaneous fistula. Treatment of Eikenella empyema using antibiotics without surgical decortication requires a prolonged course of antibiotic therapy.

Electrophysiologic studies of cutaneous nerves of the forelimb of the cat.

Kitchell, R L; Canton, D D; Johnson, R D; Maxwell, S A

1982-10-01

The cutaneous innervation of the forelimb was investigated in 20 barbiturate-anesthetized cats by using electrophysiological techniques. The cutaneous area (CA) innervated by each cutaneous nerve was delineated in at least six cats by brushing the hair in the CA with a small watercolor brush while recording from the nerve. Mapping of adjacent CA revealed larger overlap zones (OZ) than were noted in the dog. Remarkable findings were that the brachiocephalic nerve arose from the axillary nerve and the CA comparable to that supplied by the cutaneous branch of the brachiocephalic nerve in the dog was supplied by a cutaneous branch of the suprascapular nerve. The CA supplied by the communicating branch from the musculocutaneous to the median nerve was similar in both species except that the communicating branch arose proximal to any other branches of the musculocutaneous nerve in the cat, whereas it was a terminal branch in the dog. The superficial branch of the radial nerve gave off cutaneous brachial branches in the cat proximal to the lateral cutaneous antebrachial nerve. The CA of the palmar branches of the ulnar nerve did not completely overlap the CA of the palmar branches of the median nerve as occurred in the dog; thus an autonomous zone (AZ) for the CA of the palmar branches of the median nerve is present in the cat, whereas no AZ existed for the CA of this nerve in the dog.

2005-12-01

To accurately quantify the different outcomes of Leishmania major infection and to evaluate the fraction of zoonotic cutaneous leishmaniasis (ZCL) cases prevented by naturally acquired leishmanin skin test (LST) reactivity, a cohort of 470 children was followed up in 2 endemic foci, Remada and Dhiba, in southern Tunisia. During May 1997, before the ZCL emergence season, LST was performed, and results were reassessed 12 months later. Active case detection during the ZCL emergence season showed a high incidence of ZCL: 57.0% in Remada and 13.7% in Dhiba. The preventive fraction of ZCL conferred by LST reactivity increased proportionally with the reaction size before the emergence season, revealing a dose-response effect of approximately 70%. In addition, asymptomatic L. major infection appeared to be a significant form of natural immunization, particularly in the context of relatively low transmission. These findings may help in the design and evaluation of vaccines.

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.

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

Cutaneous sporotrichosis as an occupational disease: Case report

OpenAIRE

César Bimbi; Piotr Brzezinski

2017-01-01

Subcutaneous mycoses are not rare in Latin America. In Brazil, sporotrichosis was once almost exclusively found in rural areas, but in recent years it changed its profile and has been more frequent among urban adults. Cutaneous sporotrichosis is acquired from saprophytic dimorphic fungus Sporothrix schenckii usually found in soil, vegetation, and especially decaying organic matter in tropical, subtropical, and humid environments through cutaneous inoculation. The fungus abundantly grows on de...

[Cutaneous myiasis--a vacation souvenir].

Science.gov (United States)

Frieling, U; Nashan, D; Metze, D

1999-03-01

Cutaneous myiasis is a temporary infestation of the skin with fly larvae. Travelling to subtropical areas accounts for a higher risk and increasing incidence in Europeans. In Middle- and South American myiasis is mainly caused by the botfly (Dermatobia hominis). Blood-suckling arthropods, usually mosquitoes, transmit the larvae of the botfly via phoresis, a unique mechanism of egg deposition. In Africa cutaneous myiasis is mostly due to the tumbu fly (Cordylobia anthropophaga). Infection with the tumbu fly larvae occurs after direct contact with the eggs that are often deposited in clothes and towels. Clinically an abscess-like lesion develops. Creeping sensations of movement under the skin are occasionally described. Following hatching, spontaneous healing can normally be expected, although extraction of the larvae is recommended to prevent abscess formation and superinfection.

2016-05-01

Disease-specific skin lesions are rare in patients with multiple myeloma (MM). We sought to further characterize the clinical and pathologic features of patients with cutaneous involvement with MM. We identified 13 patients with cutaneous lesions of MM. Cutaneous lesions consisted of pink, red, and violaceous papules, nodules, and/or plaques that varied in size. Histopathology revealed atypical plasma cells with occasional plasmablastic features. MM had aggressive biologic features and was at an advanced stage in the majority of patients. Despite aggressive management, including chemotherapy and stem-cell transplantation, most patients died of progressive disease within a few months after the development of cutaneous lesions. The study group was relatively small. Cutaneous involvement with MM is associated with aggressive biologic behavior and short survival. Copyright © 2015 American Academy of Dermatology, Inc.

Rituximab in the treatment of primary cutaneous B-cell lymphoma: a review.

Science.gov (United States)

Fernández-Guarino, M; Ortiz-Romero, P L; Fernández-Misa, R; Montalbán, C

2014-06-01

Rituximab is a chimeric mouse-human antibody that targets the CD20 antigen, which is found in both normal and neoplastic B cells. In recent years, it has been increasingly used to treat cutaneous B-cell lymphoma and is now considered an alternative to classic treatment (radiotherapy and surgery) of 2 types of indolent lymphoma, namely, primary cutaneous follicle center lymphoma and primary cutaneous marginal zone B-cell lymphoma. Rituximab is also administered as an alternative to polychemotherapy in the treatment of primary cutaneous large B-cell lymphoma, leg type. Its use as an alternative drug led to it being administered intralesionally, with beneficial effects. In the present article, we review the literature published on the use of rituximab to treat primary cutaneous B-cell lymphoma. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

Role of peripheral eosinophilia in adverse cutaneous drug reactions.

Science.gov (United States)

Drago, F; Cogorno, L; Agnoletti, A F; Parodi, A

2015-01-01

The objective of this retrospective study was to verify whether peripheral eosinophilia (PE) may be a marker of severity for adverse cutaneous drug reactions (ACDR). We investigated for PE in sixty-three patients diagnosed as adverse cutaneous drug reactions. All the patients underwent blood tests at baseline visit. Only patients that showed a very likely connection between ACDR and the suspected causative drug were induced in the study. We found that 11 out of 63 patients (17%) presented PE for values ≥ 0.6 x 10(9) cells/l or for a percentage of total leukocytes ≥ 6%. These 11 patients compared to patients without eosinophilia had a longer recovery time, they showed diffuse severe cutaneous reactions and they all needed a systemic therapy compared to the 41% of patients without eosinophilia. These outcomes prompt us to believe that peripheral eosinophilia may be an index of severity for adverse cutaneous drug reactions. Therefore, we suggest physicians to always detect the presence of peripheral eosinophilia in order to not underestimate the reaction and to promptly start an appropriate therapy.

Histological grading patterns in patients of cutaneous leishmaniasis

International Nuclear Information System (INIS)

Saleem, K.; Ayaz, B.; Shaikh, A.

2007-01-01

To determine the histological grading patterns in a cohort of hospitalized patients of cutaneous leishmaniasis. One hundred patients of Cutaneous Leishmaniasis (CL), admitted in dermatology wards at PNS Shifa Hospital, Karachi, were examined. Only admitted patients of all ages and both sexes were included in the study. Patients of CL, who had received or were receiving systemic treatment were excluded. The lesions having marked secondary bacterial infection were also excluded. Initial diagnosis was clinical. History of being to an endemic area supported the diagnosis. The lesions were divided in two groups. Early, with duration less than 03 months and late, with duration between 3 and 12 months. The clinical lesions were noted as nodules, plaques, ulcers, crusted ulcers, lupoid lesions and plaques with scarring. Three types of skin smears (slit skin smear, saline aspirate smear and dab smear) were taken and examined with Giemsa stain. Cultures were performed on Nicolle-Novy-MacNeal (NNN) culture medium from Defense Scientific and Technology Organization (DESTO) Lab., Pakistan. Incisional skin biopsies were done. The biopsy specimens were examined by hemotoxylin and eosin stain (H and E stain). The number of Leishmania Tropica (LT) bodies was graded according to modified Ridley's parasitic index 1983. Clinical features were correlated with the histological patterns. Five histological patterns were identified in current study: 1) diffuse dermal infiltration without necrosis, 2) patchy dermal infiltration, 3) diffuse dermal infiltration with necrosis, 4) early reactive granuloma formation and 5) established epithelioid granuloma formation. LT bodies were identified in 75% of cases. Epidermal features were non-specific. The early lesions presented with diffuse infiltrate and late lesions showed granuloma formation. Five distinct types of histological patterns of CL have been recognized in this study. The early lesions presented with diffuse infiltrate and late lesions

Zosteriform impetigo: Wolf's isotopic response in a cutaneous immunocompromised district.

Science.gov (United States)

Cohen, Philip R

2015-07-01

Impetigo can result from Staphylococcus aureus (S. aureus). Wolf's isotopic response is the occurrence of a new cutaneous disorder at the site of a previously healed disease. A cutaneous immunocompromised district is an area of skin that is more vulnerable than the rest of the individual's body. To describe a man with impetigo localized to a unilateral dermatome and review the clinical features of other patients with zosteriform Staphylococcus aureus cutaneous infection. PubMed was used to search the following terms, separately and in combination: cutaneous, dermatome, dermatomal, district, herpes, immunocompromised, impetigo, infection, isotopic, response, skin, staphylococcal, Staphylococcus aureus, Wolf, zoster, zosteriform. All papers were reviewed and relevant manuscripts, along with their reference citations, were evaluated. Crusted, eroded and intact, erythematous papules and nodules acutely presented localized to the mandibular branch of the left trigeminal nerve on the face of a 66-year-old man; he did not recall a prior episode of varicella-zoster virus infection in that area. A bacterial culture isolated methicillin-susceptible S. aureus. Viral cultures and direct fluorescent absorption studies were negative for herpes simplex and herpes zoster virus. All of the lesions resolved after oral treatment with cefdinir. Impetigo and/or furunculosis in a zosteriform distribution have also been described in 3 additional patients. The bacterial culture showed either methicillin-susceptible or methicillin-resistant S. aureus; the skin infection resolved after treatment with oral antibiotics; however one man experienced 2 recurrences in the same area. Zosteriform cutaneous staphylococcal impetigo may be an example of Wolf's isotopic response in a cutaneous immunocompromised district.

The main goal of the study was to investigate the interaction between bupivacaine and dopamine on local analgesia. After the blockade of the cutaneous trunci muscle reflex (CTMR) responses, which occurred following the drugs were subcutaneously injected in rats, the cutaneous analgesic effect of dopamine in a dosage-dependent fashion was compared to that of bupivacaine. Drug-drug interactions were evaluated by isobolographic methods. We showed the dose-dependent effects of dopamine on infiltrative cutaneous analgesia. On the 50% effective dose (ED50) basis, the rank of drug potency was bupivacaine (1.99 [1.92-2.09] μmol/kg) greater than dopamine (190 [181-203] μmol/kg) (Pbupivacaine. The addition of dopamine to the bupivacaine solution exhibited a synergistic effect. Our pre-clinical data showed that dopamine produced a dose-dependent effect in producing cutaneous analgesia. When compared with bupivacaine, dopamine produced a lesser potency with a similar duration of cutaneous analgesia. Dopamine added to the bupivacaine preparation resulted in a synergistic analgesic effect. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Non-tuberculous mycobacterial skin infections have an increasing incidence. In immunocompetent patients, they usually follow local trauma. We present a case of cutaneous Mycobacterium abscessus infection following mesotherapy. The lesions were successfully treated with a combination of clarithromycin, ciprofloxacin, and doxycycline. Atypical mycobacterial infection should be suspected in patients who develop late-onset skin and soft tissue infection after cutaneous injury, injection, and surgical intervention, particularly if they do not respond to conventional antibiotic treatment.

Experimental FT-IR and FT-Raman spectra of 2-methylphenylacetic acid (MPA) were recorded and theoretical values are also analyzed. The non-linear optical (NLO) properties were evaluated by determination of first (5.5053 × 10- 30 e.s.u.) and second hyper-polarizabilities (7.6833 × 10- 36 e.s.u.) of the title compound. The Multiwfn package is used to find the weak non-covalent interaction (Van der Wall interaction) and strong repulsion (steric effect) of the molecule and examined by reduced density gradient. The molecular electrostatic potential (MEP) analysis used to find the most reactive sites for the electrophilic and nucleophilic attack. The chemical activity (electronegativity, hardness, chemical softness and chemical potential) of the title compound was predicted with the help of HOMO-LUMO energy values. The natural bond orbital (NBO) has been analyzed the stability of the molecule arising from the hyper-conjugative interaction. DSSCs were discussed in structural modifications that improve the electron injection efficiency of the title compound (MPA). The Fukui functions are calculated in order to get information associated with the local reactivity properties of the title compound. The binding sites of the two receptors were reported by molecular docking field and active site bond distance is same 1.9 Å. The inhibitor of the title compound forms a stable complex with 1QYV and 2H1K proteins at the binding energies are - 5.38 and - 5.85 (Δ G in kcal/mol).

Bowden, Jocelyn L; McNulty, Penelope A

Cutaneous sensation deteriorates with age. It is not known if this change is consistent over the entire hand or if sensation is affected by changes in skin mechanics. Cutaneous perceptual thresholds were tested at eight sites in the glabrous skin and two in the hairy skin of both hands in 70 subjects (20-88 years), five male and five female per decade, using calibrated von Frey filaments, two-point discrimination, and texture discrimination. Venous occlusion at the wrist (40 ± 10 mmHg) and moisturizer were used to alter skin mechanics. Cutaneous thresholds increased significantly with age (p sensation varied according to the site tested with smaller changes on the fingers compared to the palm. Two-point discrimination deteriorated with age (p = 0.046), but with no interaction between sex, handedness, or changes in skin mechanics. There were no significant differences for texture discrimination. Changes in skin mechanics improved cutaneous thresholds in the oldest males after moisturizing (p = 0.001) but not otherwise. These results emphasize the complex pattern of age-related deterioration in cutaneous sensation with differences between sexes, the hands, sites on the hand, and the mode of testing. As the index fingertip is not a sensitive indicator of sensory decline, the minimum assessment of age-related changes in cutaneous sensation should include both hands, and sites on the palm.

2013-10-01

Since the recognition of the anaplastic large-cell lymphomas in the 1980s, much has been learned about the diagnosis, clinical presentation, and treatment of these malignant conditions. The systemic and primary cutaneous types of anaplastic large cell lymphomas have been differentiated on clinical and immunophenotypical findings, but further research is required to elucidate their exact etiologies and pathogeneses. Primary cutaneous anaplastic large-cell lymphoma has a 95% disease-specific 5-year survival, owing partly to the relatively benign course of the disease and partly to the variety of effective treatments that are available. As with many other oncological diseases, new drugs are continually being tested and developed, with immunotherapy and biological response modifiers showing promise.

Disseminated cutaneous sporotrichosis in an immunocompetent individual.

Science.gov (United States)

Yap, Felix Boon-Bin

2011-10-01

Sporotrichosis is a subacute or chronic fungal infection caused by the ubiquitous fungus Sporothrix schenckii. Disseminated cutaneous sporotrichosis is an uncommon entity and is usually present in the immunosuppressed. Here, a case of disseminated cutaneous sporotrichosis in an immunocompetent patient is reported. This 70-year-old healthy woman presented with multiple painful ulcerated nodules on her face and upper and lower extremities of 6-month duration, associated with low-grade fever, night sweats, loss of appetite, and loss of weight. Histopathological examination of the skin biopsy revealed epidermal hyperplasia and granulomatous inflammation in the dermis, with budding yeast. Fungal culture identified S. schenckii. She had total resolution of the lesions after 2 weeks of intravenous amphotericin B and 8 months of oral itraconazole. All investigations for underlying immunosuppression and internal organ involvement were negative. This case reiterates that disseminated cutaneous sporotrichosis, although common in the immunosuppressed, can also be seen in immunocompetent patients.

Cutaneous tuberculosis forms a small subset of extra pulmonary tuberculosis and has a worldwide distribution. The present study is an attempt to find out the incidence, clinical spectrum, and histopathological features of cutaneous tuberculosis. A total of 42 cases of newly diagnosed patients of cutaneous tuberculosis attending dermatology out patient department over a period of 1 year were included in the study. A detailed clinical examination and investigations including histopathological examination were carried out. Scrofuloderma was the most common form seen in 50% cases followed by lupus vulgaris in 42.86%, tuberculosis verrucosa cutis in 4.76%, and lichen scrofulosorum in 2.38% cases. The Mantoux test was positive in 83.33% cases. Characteristic tuberculoid granulomas were seen in 72.22% cases of lupus vulgaris, 42.86% cases of scrofuloderma and all cases of tuberculosis verrucosa cutis and lichen scrofulosorum. Cutaneous tuberculosis is still highly prevalent in upper Assam. Early diagnosis and treatment are essential to prevent its complications.

BACKGROUND: An increasing number of drugs have been linked to drug-induced subacute cutaneous lupus erythematosus (DI-SCLE). The recognition and management of DI-SCLE can be challenging, as the condition may be triggered by different classes of drugs after variable lengths of time. OBJECTIVES......: To determine the proportion of patients with cutaneous lupus erythematosus (CLE) whose drugs are an inducing or aggravating factor. MATERIALS & METHODS: We conducted a retrospective chart review of patients diagnosed with CLE at a dermatological department over a 21-year period. We registered clinical......, serological, and histological data with a focus on drug intake.

The purpose of the study was to estimate the ability of L-tyrosine to induce cutaneous analgesia and to investigate the interaction between L-tyrosine and the local anesthetic lidocaine. After subcutaneously injecting the rats with L-tyrosine and lidocaine in a dose-dependent manner, cutaneous analgesia (by blocking the cutaneous trunci muscle reflex-CTMR) was evaluated in response to the local pinprick. The drug-drug interaction was analyzed by using an isobolographic method. We showed that both L-tyrosine and lidocaine produced dose-dependent cutaneous analgesia. On the 50% effective dose (ED50) basis, the rank of drug potency was lidocaine (5.09 [4.88-5.38] μmol)>L-tyrosine (39.1 [36.5-41.8] μmol) (Ptyrosine lasted longer than that caused by lidocaine (Ptyrosine exhibited an additive effect on infiltrative cutaneous analgesia. Our pre-clinical study demonstrated that L-tyrosine elicits the local/cutaneous analgesia, and the interaction between L-tyrosine and lidocaine is additive. L-tyrosine has a lower potency but much greater duration of cutaneous analgesia than lidocaine. Adding L-tyrosine to lidocaine preparations showed greater duration of cutaneous analgesia compared with lidocaine alone. Copyright © 2015 Elsevier B.V. All rights reserved.

We report a case of visceral leishmaniasis (VL) with cutaneous lesions in a patient infected with human immunodeficiency virus (HIV). The cutaneous lesions consisted of erythematous papules on the legs. Biopsy of one lesion showed abundant Leishmania amastigotes within epithelial cells of an eccrine sweat gland in the dermis. Leishmania organisms were also found in a blood smear. Rapid and complete clearance of the cutaneous lesions was achieved after antimony therapy. Cutaneous lesions in VL are being reported increasingly frequently in patients with HIV infection and their significance remains in discussion.

Abstract Cutaneous vasculitis may be associated with malignancies, and may behave as a paraneoplastic syndrome. This association has been reported in a variable proportion of patients depending on population selection. We conducted the current study to assess the frequency, clinical features, treatment, and outcome of paraneoplastic vasculitis in a large unselected series of 766 patients with cutaneous vasculitis diagnosed at a single university hospital. Sixteen patients (10 men and 6 women; mean age ± standard deviation, 67.94 ± 14.20 yr; range, 40–85 yr) presenting with cutaneous vasculitis were ultimately diagnosed as having an underlying malignancy. They constituted 3.80% of the 421 adult patients. There were 9 hematologic and 7 solid underlying malignancies. Skin lesions were the initial clinical presentation in all of them, and the median interval from the onset of cutaneous vasculitis to the diagnosis of the malignancy was 17 days (range, 8–50 d). The most frequent skin lesions were palpable purpura (15 patients). Other clinical manifestations included constitutional syndrome (10 patients) and arthralgia and/or arthritis (4 cases). Hematologic cytopenias (11 cases) as well as immature peripheral blood cells (6 cases) were frequently observed in the full blood cell count, especially in those with vasculitis associated with hematologic malignancies. Specific treatment for vasculitis was prescribed in 10 patients; nonsteroidal antiinflammatory drugs (4 patients), corticosteroids (3 patients), chloroquine (1 patient), antihistamines (1 patient), and cyclophosphamide (1 patient). Ten patients died due to the malignancy and 6 patients recovered following malignancy therapy. Patients with paraneoplastic vasculitis were older, more frequently had constitutional syndrome, and less frequently had organ damage due to the vasculitis than the remaining patients with cutaneous vasculitis. In summary, cutaneous paraneoplastic vasculitis is an entity not uncommonly

Full Text Available Non-tuberculous mycobacterial skin infections have an increasing incidence. In immunocompetent patients, they usually follow local trauma. We present a case of cutaneous Mycobacterium abscessus infection following mesotherapy. The lesions were successfully treated with a combination of clarithromycin, ciprofloxacin, and doxycycline. Atypical mycobacterial infection should be suspected in patients who develop late-onset skin and soft tissue infection after cutaneous injury, injection, and surgical intervention, particularly if they do not respond to conventional antibiotic treatment.

Rhodotorula is a ubiquitous environmental and commensal yeast, and an emerging opportunistic pathogen, particularly in immunocompromised individuals. Clinical infections with Rhodotorula have been increasingly recognized over the past 30 years; however, infections in solid-organ transplant recipients are uncommon, and cutaneous manifestations have rarely been reported. We describe a 59-year-old male renal transplant recipient, who developed cutaneous infection with Rhodotorula upon failure of his graft and commencement of haemodialysis. © 2016 British Association of Dermatologists.

Unmyelinated cutaneous axons are vulnerable to physical and metabolic injury, but also capable of rapid regeneration. This balance may help determine risk for peripheral neuropathy associated with diabetes or metabolic syndrome. Capsaicin application for 48 hours induces cutaneous fibers to die back into the dermis. Regrowth can be monitored by serial skin biopsies to determine intraepidermal nerve fiber density (IENFD). We used this capsaicin axotomy technique to examine the effects of exercise on cutaneous regenerative capacity in the setting of metabolic syndrome. Baseline ankle IENFD and 30-day cutaneous regeneration after thigh capsaicin axotomy were compared for participants with type 2 diabetes (n = 35) or metabolic syndrome (n = 32) without symptoms or examination evidence of neuropathy. Thirty-six participants (17 with metabolic syndrome) then joined twice weekly observed exercise and lifestyle counseling. Axotomy regeneration was repeated in month 4 during this intervention. Baseline distal leg IENFD was significantly reduced for both metabolic syndrome and diabetic groups. With exercise, participants significantly improved exercise capacity and lower extremity power. Following exercise, 30-day reinnervation rate improved (0.051 ± 0.027 fibers/mm/day before vs 0.072 ± 0.030 after exercise, p = 0.002). Those who achieved improvement in more metabolic syndrome features experienced a greater degree of 30-day reinnervation (p Metabolic syndrome was associated with reduced baseline IENFD and cutaneous regeneration capacity comparable to that seen in diabetes. Exercise-induced improvement in metabolic syndrome features increased cutaneous regenerative capacity. The results underscore the potential benefit to peripheral nerve function of a behavioral modification approach to metabolic improvement. © 2014 American Neurological Association.

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

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

Tumors that develop in old burn scars are usually squamous cell carcinomas. Sarcomas have also been reported, albeit rarely. To our knowledge, there has been only one case report of an extraskeletal osteosarcoma arising in a prior burn scar reported in the English-language literature, mainly discussing the clinicopathological features. Herein, we present a case of cutaneous osteosarcoma visualized as a mineralized soft-tissue mass arising from the scar associated with a previous skin burn over the back. This seems to be the first report describing the imaging features of a cutaneous osteosarcoma from an old burn scar. (orig.)

Isolated cutaneous involvement in a child with nodal anaplastic large cell lymphoma

Full Text Available Non-Hodgkin lymphoma is a common childhood T-cell and B-cell neoplasm that originates primarily from lymphoid tissue. Cutaneous involvement can be in the form of a primary extranodal lymphoma, or secondary to metastasis from a non-cutaneous location. The latter is uncommon, and isolated cutaneous involvement is rarely reported. We report a case of isolated secondary cutaneous involvement from nodal anaplastic large cell lymphoma (CD30 + and ALK + in a 7-year-old boy who was on chemotherapy. This case is reported for its unusual clinical presentation as an acute febrile, generalized papulonodular eruption that mimicked deep fungal infection, with the absence of other foci of systemic metastasis.

Primary Cutaneous Diffuse Large B-Cell Lymphoma – a Case Report

Directory of Open Access Journals (Sweden)

Milovanović Milena

2017-06-01

Full Text Available In 2005, the World Health Organization - European Organization for Research and Treatment of Cancer (WHOEORTC classified cutaneous B-cell lymphomas into 4 categories: primary cutaneous marginal zone B-cell lymphoma (PCMZL, primary cutaneous follicle center lymphoma (PCFCL, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT, and primary cutaneous diffuse large B-cell lymphoma, other (PCDLBCL-O. The absence of evident extra-cutaneous disease is a necessary condition for the diagnosis of primary cutaneous B-cell lymphomas, because they have a completely different clinical behavior and prognosis from their nodal counterparts. PCDLBCL-O basically represents a morphological variation, lacking the typical features of PCDLBCLLT, neither confirming the definition of PCFCCL, but on the clinical ground, its behavior seems at least to partially overlap the indolent course of PCFCCL. In fact, the present WHO lymphoma classification from 2008 overcame the previous WHO-EORTC classification, including at least a part of PCDLBCL-O within the spectrum of PCFCCL. However, owing to the rarity and heterogeneity of the PCDLBCL-O, the precise clinicopathological characteristics have not been well characterized and the optimal treatment for this group of lymphomas is yet to be defined. Nevertheless, dermatologists and pathologists should be aware of this entity in order to avoid unnecessary aggressive treatment. We present a case of a 46-year-old Caucasian male with one large round-shaped tumor and a few scattered nodules localized on the back. The histopathological features of the lesion corresponded to PCDLBCL-O. The patient follow-up showed that he was disease-free three months after surgical excision of the lesions and adjuvant local radiotherapy. No additional therapy was introduced, including chemotherapy with rituximab, cyclophosphamide, doxorubicin hydrochloride, oncovin, prednisolone (R-CHOP.

Cutaneous Adverse Events of Targeted Therapies for Hematolymphoid Malignancies.

Ransohoff, Julia D; Kwong, Bernice Y

2017-12-01

The identification of oncogenic drivers of liquid tumors has led to the rapid development of targeted agents with distinct cutaneous adverse event (AE) profiles. The diagnosis and management of these skin toxicities has motivated a novel partnership between dermatologists and oncologists in developing supportive oncodermatology clinics. In this article we review the current state of knowledge of clinical presentation, mechanisms, and management of the most common and significant cutaneous AEs observed during treatment with targeted therapies for hematologic and lymphoid malignancies. We systematically review according to drug-targeting pathway the cutaneous AE profiles of these drugs, and offer insight when possible into whether pharmacologic target versus immunologic modulation primarily underlie presentation. We include discussion of tyrosine kinase inhibitors (imatinib, dasatinib, nilotinib, bosutinib, ponatinib), blinatumomab, ibrutinib, idelalisib, anti-B cell antibodies (rituximab, ibritumomab, obinutuzumab, ofatumumab, tositumomab), immune checkpoint inhibitors (nivolumab, pembrolizumab), alemtuzumab, brentuximab, and proteasome inhibitors (bortezomib, carfilzomib, ixazomib). We highlight skin reactions seen with antiliquid but not solid tumor agents, draw attention to serious cutaneous AEs that might require therapy modification or cessation, and offer management strategies to permit treatment tolerability. We emphasize the importance of early diagnosis and treatment to minimize disruptions to care, optimize prognosis and quality of life, and promptly address life-threatening skin or infectious events. This evolving partnership between oncologists and dermatologists in the iterative characterization and management of skin toxicities will contribute to a better understanding of these drugs' cutaneous targets and improved patient care.

Sara Soares

2018-04-01

Full Text Available Introduction: Cutaneous Larva Migrans is a dermatosis caused by nemantode parasites, mainely Ancylostoma brasiliensis and Ancylostoma caninus. It is an endemic disease in tropical countries but a rare diagnosis in the rest of the world. Case Report: We report the case of a ten-year-old child emigrated from Angola. The physical examination showed scarring injuries from previous incisions made as a form of treatment as well as a serpiginous lesion on the dorsum of the left foot, compatible with cutaneous Larva Migrans. The patient was started on albendazole and complete resolution of symptoms was obtained after one week. About that time, the patient’s brother, who had the same symptoms on both feet, was submitted to the same treatment, also with resolution of symptoms. Discussion: The authors wish to enphasize the relevance of this case due to the migration from countries with high prevalence of cutaneous Larva Migrans.

Chromatophoromas are neoplasms arising from pigment-bearing cells (chromatophores) of the dermis. While isolated cases have been reported in the literature, the prevalence and biological behavior of chromatophoromas in snakes are unknown. Forty-two chromatophoromas were identified among 4663 submissions (0.9%) to a private diagnostic laboratory in a 16-year period. The most commonly affected snakes were colubrids (23 cases, 55%) and vipers (8 cases, 19%). The San Francisco garter snake was the most commonly affected species (6 cases; 14% of all affected snake species and 3.7% of all garter snake submissions). No sex predilection was found. The age of 28 snakes ranged from 5 to 27 years. Single cutaneous chromatophoromas were most commonly observed and presented as pigmented cutaneous masses or plaques along any body segment. Euthanasia or death due to progressive neoplastic disease or metastasis was reported in 8 (19%) and 4 (10%) cases, respectively. The survival time of 4 animals ranged from 4 to 36 months. Microscopically, xanthophoromas, iridophoromas, melanocytic neoplasms, and mixed chromatophoromas were identified, with melanocytic neoplasms being most common. Microscopic examination alone was generally sufficient for the diagnosis of chromatophoroma, but immunohistochemistry for S-100 and PNL-2 may be helpful for diagnosing poorly pigmented cases. Moderate to marked nuclear atypia appears to be consistently present in cutaneous chromatophoromas with a high risk of metastasis, while mitotic count, lymphatic invasion, the level of infiltration, and the degree of pigmentation or ulceration were not reliable predictors of metastasis. © The Author(s) 2016.

Purpose: A retrospective review analyzed the survival and freedom from relapse of patients with stage IE or IIE primary cutaneous lymphoma (non mycosis fungoides) after treatments with radiation therapy alone (XRT), chemotherapy alone (RX) or combined modality therapy (CMT). Methods and Materials: Fifty two patients with stage IE-IIE cutaneous lymphoma treated at Stanford University Hospital were reviewed. The median age was 57, with a range of 26 to 94 and a male to female ratio of 1.21:1. Patients were staged according to the Ann Arbor System. Pathology was classified according to the Working Formulation. Treatment outcomes were compared using Kaplan-Meier survival curves with a Gehan p-value test. Results: The follow up range was 6 months to 22 years (median 7 years.) Twenty one percent of patients had low grade, 63% had intermediate grade and 15% had high grade lymphoma. The most common histologic subtype was diffuse large cell lymphoma Thirty two patients received radiation alone as initial treatment and sixteen patients received combined modality as initial treatment. Four patients received chemotherapy alone. The only significant prognostic factor for survival was the stage at diagnosis. Patients with stage IE disease had a longer actuarial survival (5-yr=79%, 10-yr=71%), as compared to those with stage IIE (5-yr=49%, 10-yr=33%), (p=0.029). The only significant prognostic factor for freedom from relapse was the initial treatment. Initial combined modality treatment lead to a longer freedom from relapse compared to patients treated with radiation alone (p=0.002), (median 5 years vs. 1.2 years). Despite this, the actuarial overall survival in the combined modality group and the radiation alone group are similar (median survival 7.7 and 8 years). The efficacy of either radiation or chemotherapy as salvage treatment after radiation failure was equivalent and both salvage treatments lead to equally long survival and freedom from second relapse.

2018-07-01

A 19-year-old man suffering from testicular choriocarcinoma presented to the dermatology department with a cutaneous metastasis on his head. This metastasis was the first sign of disease that led to medical consultation. Histopathology revealed cytotrophoblasts and syncytiotrophoblasts, the later expressing human chorionic gonadotropin antigen. Whole body computed tomography showed multiple metastases of the brain, lung, liver, bone, paraaortic lymph nodes and left uvea; the primary was found in the left testicle. Despite neurosurgical intervention and chemotherapy the patient died 9 days after the biopsy of the cutaneous metastasis. Cutaneous metastases of testicular choriocarcinoma are exceptionally rare, with fewer than a dozen cases reported in the English-language literature. The present case highlights that testicular choriocarcinoma metastatic to the skin should be included in the differential of cutaneous scalp tumors. © 2018 John Wiley & Sons A/S.

Cutaneous leiomyosarcoma (CLM) is a very rare smooth muscle tumour that accounts for about 2-3% of all superficial soft tissue sarcomas. Although the development of various malignancies in scar tissue is well known, we report the first case of a CLM developing in a small pox scar. A 66-year-old man presented with a painless, slow-growing lump in a small pox scar on his left shoulder. Histological biopsies showed the lesion to be a primary, well-differentiated cutaneous leiomyosarcoma. A CT scan of the thorax was conducted, which showed no signs of metastases. The complete lesion was then surgically excised, and histopathological examination revealed a radically excised cutaneous type leiomyosarcoma After 13 months' review the patient was doing well with no evidence of tumour recurrence. This is the first report of a CLM arising in a small pox scar. Although the extended time interval between scarring and malignant changes makes it difficult to advise strict follow-up for patients with small pox scars, one should be aware that atypical changes and/or symptoms occurring in a small pox scar could potentially mean malignant transformation.

Full Text Available Abstract Background Cutaneous leiomyosarcoma (CLM is a very rare smooth muscle tumour that accounts for about 2–3% of all superficial soft tissue sarcomas. Although the development of various malignancies in scar tissue is well known, we report the first case of a CLM developing in a small pox scar. Case presentation A 66-year-old man presented with a painless, slow-growing lump in a small pox scar on his left shoulder. Histological biopsies showed the lesion to be a primary, well-differentiated cutaneous leiomyosarcoma. A CT scan of the thorax was conducted, which showed no signs of metastases. The complete lesion was then surgically excised, and histopathological examination revealed a radically excised cutaneous type leiomyosarcoma After 13 months’ review the patient was doing well with no evidence of tumour recurrence. Conclusions This is the first report of a CLM arising in a small pox scar. Although the extended time interval between scarring and malignant changes makes it difficult to advise strict follow-up for patients with small pox scars, one should be aware that atypical changes and/or symptoms occurring in a small pox scar could potentially mean malignant transformation.

Knowing the size of a cutaneous lesion can be important for tracking its progression over time, selecting the proper treatment modality, surgical planning, determining prognosis, and accurate billing. However, providers vary in their consistency, accuracy, and methods of measuring cutaneous lesions. To investigate the clinical practices of US dermatologists and dermatologic surgeons regarding how they determine the size of cutaneous lesions. A survey was electronically distributed to members of the American Society for Dermatologic Surgery. Four hundred twenty-six dermatologists completed the online survey. When a lesion is suspected to be malignant, 85% of respondents obtained exact measurements most, if not all, of the time; however, only 8% did for benign lesions. Most providers determined lesion sizes themselves rather than delegating to staff. When performing visual estimation, approximately three-quarters believed that they were accurate to within 1 to 2 mm. The top reasons for obtaining exact measurements were for tracking atypical pigmented lesions, determining treatment pathways, and accurate billing. The majority of respondents believed that lesion size affected management decisions; however, the need for exact measurement remains controversial, particularly for benign lesions. Future studies may investigate whether taking exact versus estimated measurements has an effect on outcomes.

Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct

We report secondary cutaneous infections in the mouse papillomavirus (MmuPV1)/mouse model. Our previous study demonstrated that cutaneous MmuPV1 infection could spread to mucosal sites. Recently, we observed that mucosal infections could also spread to various cutaneous sites including the back, tail, muzzle and mammary tissues. The secondary site lesions were positive for viral DNA, viral capsid protein and viral particles as determined by in situ hybridization, immunohistochemistry and transmission electron microscopy analyses, respectively. We also demonstrated differential viral production and tumour growth at different secondarily infected skin sites. For example, fewer viral particles were detected in the least susceptible back tissues when compared with those in the infected muzzle and tail, although similar amounts of viral DNA were detected. Follow-up studies demonstrated that significantly lower amounts of viral DNA were packaged in the back lesions. Lavages harvested from the oral cavity and lower genital tracts were equally infectious at both cutaneous and mucosal sites, supporting the broad tissue tropism of this papillomavirus. Importantly, two secondary skin lesions on the forearms of two mice displayed a malignant phenotype at about 9.5 months post-primary infection. Therefore, MmuPV1 induces not only dysplasia at mucosal sites such as the vagina, anus and oral cavity but also skin carcinoma at cutaneous sites. These findings demonstrate that MmuPV1 mucosal infection can be spread to cutaneous sites and suggest that the model could serve a useful role in the study of the viral life cycle and pathogenesis of papillomavirus.

The involvement of cutaneous receptors in the biological effects of electromagnetic millimeter waves

Full Text Available The involvement of peripheral nerve terminations in the mechanisms of action of electromagnetic millimeter waves (mmW was assessed. It is currently thought that mmW could be used in noninvasive complementary therapy because of their analgesic effect. However, the mechanisms of their antinociceptive effect and non-ionizing radiation are the subjects of controversy. The mechanisms of interaction of mmW and the cutaneous tissue have not been elucidated. We observed mast cell degranulation at the place of mmW action, a decrease of chronaxie and Turck reflex time, an increase in the number of afferent impulses after sciatic nerve at stimulation, as well as an increase electrocardiogram R-R interval of isolated frog heart after application of mmW. Based on these investigations, we propose that electromagnetic waves of millimeter length modify, through indirect mechanisms, the excitability and reactivity of peripheral nerve terminations.

2010-01-01

Cutaneous angiomatosis was diagnosed in an adult female llama (Lama glama). Lesions were raised or plaque-like, erythematous, firm to soft in consistency and were observed on the face and skin of the axillary, abdominal, perineal and inguinal regions. The lesions were not painful or pruritic. Microscopical examination revealed an irregular parakeratotic lamellar hyperkeratosis associated with diffuse proliferation of arterioles and venules in the superficial dermis. Immunohistochemical analysis determined that the cells forming these vessels and perivascular cells expressed factor VIII-related antigen, vascular endothelial growth factor (VEGF), CD31 and smooth-muscle alpha-actin. These studies confirmed the diagnosis of cutaneous angiomatosis. Copyright 2009 Elsevier Ltd. All rights reserved.

[Primitive cutaneous Ewing's sarcoma: a diagnostic and therapeutic dilemma].

2011-05-01

Ewing's sarcoma (or peripheral neuroectodermal tumour) is generally found in bone tissue, and a primary dermal site is extremely rare. We report a case of primary cutaneous Ewing's sarcoma in a 21-year-old woman. A 21-year-old woman presented with a scapular lesion that had been slowly developing for one year. The 1-cm lesion was removed and histological examination showed proliferation of small round cells in the dermis. Immunostaining revealed cytoplasmic membrane expression of CD99 and a negative immunoprofile for other small round-cell tumors. Ewing's sarcoma fusion gene transcripts were detected using fluorescence in situ hybridization (FISH). A staging examination revealed no other abnormalities. It was decided to treat the lesion as for osseous Ewing's sarcoma with wide resection followed by systemic adjuvant chemotherapy. Cutaneous Ewing's sarcoma raises concerns about diagnosis and treatment. Owing to the non-specificity of its clinical presentation, histology and immunoprofile, diagnosis of superficial Ewing's sarcoma is difficult and numerous differential diagnoses must be considered. When dealing with a surface tumour, the diagnosis of cutaneous Ewing's sarcoma must be considered. CD99 immunostaining and molecular testing for evidence of EWSR1 rearrangement are useful investigations to confirm the diagnosis. Furthermore, modalities of treatment must be carefully discussed. Cutaneous Ewing's sarcoma is currently treated in the same way as osseous Ewing's sarcoma (wide surgical excision, adjuvant radiotherapy when surgical margins are unsatisfactory, systemic adjuvant chemotherapy, and, in some cases, bone marrow transplant). However, some studies show a more favourable prognosis for cutaneous Ewing's sarcoma than for osseous Ewing's sarcoma. We may thus ask whether such aggressive multimodal treatment is needed.

Laboudi, M

2017-02-01

The main objective of our study is to provide a comprehensive overview of the situation of cutaneous leishmaniasis in Morocco. We therefore conducted a retrospective descriptive study covering the decade 2004-2013. Data were collected from the Moroccan Ministry of Health's annual reports about the national program against leishmaniasis. These data show a regression in the cases due to Leishmania major and the persistence of L. tropica transmission. Mapping cutaneous leishmaniasis cases reported between 2004 and 2013 showed geographical changes ; the number of cases due to L. tropica were concentrated in the regions of Marrakech-Tensift-Elhaouz, Souss Massa-Draa Tadla-Azila, and Taza-Al Hoceima-Taounate. Cutaneous disease due to L. major was most common in the Souss-Massa-Draa region. Continuous monitoring of the epidemiological situation is important to assess the actions taken to reduce its incidence.

Hayashi, Keiji; Ito, Nozomi; Ichikawa, Yoko; Suzuki, Yuichi

2014-08-01

To examine the effect of postprandial thermogenesis on the cutaneous vasodilatory response, 10 healthy male subjects exercised for 30 min on a cycle ergometer at 50% of peak oxygen uptake, with and without food intake. Mean skin temperature, mean body temperature (Tb), heart rate, oxygen uptake, carbon dioxide elimination, and respiratory quotient were all significantly higher at baseline in the session with food intake than in the session without food intake. To evaluate the cutaneous vasodilatory response, relative laser Doppler flowmetry values were plotted against esophageal temperature (Tes) and Tb. Regression analysis revealed that the [Formula: see text] threshold for cutaneous vasodilation tended to be higher with food intake than without it, but there were no significant differences in the sensitivity. To clarify the effect of postprandial thermogenesis on the threshold for cutaneous vasodilation, the between-session difference in the Tes threshold and the Tb threshold were plotted against the between-session difference in baseline Tes and baseline Tb, respectively. Linear regression analysis of the resultant plot showed significant positive linear relationships (Tes: r = 0.85, P < 0.01; Tb: r = 0.67, P < 0.05). These results suggest that postprandial thermogenesis increases baseline body temperature, which raises the body temperature threshold for cutaneous vasodilation during exercise.

Cutaneous xanthomas with concurrent demodicosis and dermatophytosis in a cat.

Vogelnest, L J

2001-07-01

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

Adverse drug reactions are most commonly cutaneous in nature. Patterns of cutaneous adverse drug reactions (ADRs) and their causative drugs vary among the different populations previously studied. Our aim is to determine the clinical pattern of drug eruptions and the common drugs implicated, particularly in severe cutaneous ADRs in our population. This study was done by analyzing the database established for all adverse cutaneous drug reactions seen from January 2001 until December 2008. A total of 281 cutaneous ADRs were seen in 280 patients. The most common reaction pattern was maculopapular eruption (111 cases, 39.5%) followed by Stevens-Johnson Syndrome (SJS: 79 cases, 28.1%), drug reaction with eosinophilia and systemic symptoms (DRESS: 19 cases, 6.8%), toxic epidermal necrolysis (TEN: 16 cases, 5.7 %), urticaria/angioedema (15 cases, 5.3%) and fixed drug eruptions (15 cases, 5.3%). Antibiotics (38.8%) and anticonvulsants (23.8%) accounted for 62.6% of the 281 cutaneous ADRs seen. Allopurinol was implicated in 39 (13.9%), carbamazepine in 29 (10.3%), phenytoin in 27 (9.6%) and cotrimoxazole in 26 (9.3%) cases. Carbamazepine, allopurinol and cotrimoxazole were the three main causative drugs of SJS/TEN accounting for 24.0%, 18.8% and 12.5% respectively of the 96 cases seen whereas DRESS was mainly caused by allopurinol (10 cases, 52.6%) and phenytoin (3 cases, 15.8%). The reaction patterns and drugs causing cutaneous ADRs in our population are similar to those seen in other countries although we have a much higher proportion of severe cutaneous ADRs probably due to referral bias, different prescribing habit and a higher prevalence of HLA-B*1502 and HLA-B*5801 which are genetic markers for carbamazepine-induced SJS/TEN and allopurinol-induced SJS/TEN/DRESS respectively. The most common reaction pattern seen in our study population was maculopapular eruptions. Antibiotics, anticonvulsants and NSAIDs were the most frequently implicated drug groups. Carbamazepine

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.

2010-12-01

This study aimed to identify microRNA species involved in the earliest metastatic event in cutaneous malignant melanoma (MM). Samples from 28 patients with MM [stage T2 (tumor), M0 (distant metastasis)] were grouped by the presence of micrometastasis in the sentinel lymph nodes (N0/N1). Melanoma cells were harvested from primary, cutaneous MM tumors by laser-capture microdissection, and microRNA expression profiles were obtained by the microarray technique. Results were validated by quantitative reverse transcription PCR. We found that miR-125b was downregulated in the primary cutaneous melanomas that produced early metastases (T2, N1, M0) compared with the sentinel lymph node-negative (T2, N0, M0) melanomas. MiR-125b has earlier been found to be downregulated in other tumor types and in atypic naevi compared with the common acquired naevi. In conclusion, miR-125b may be involved in an early progression of cutaneous MM.

The contribution of cutaneous and kinesthetic sensory modalities in haptic perception of orientation.

Frisoli, Antonio; Solazzi, Massimiliano; Reiner, Miriam; Bergamasco, Massimo

2011-06-30

The aim of this study was to understand the integration of cutaneous and kinesthetic sensory modalities in haptic perception of shape orientation. A specific robotic apparatus was employed to simulate the exploration of virtual surfaces by active touch with two fingers, with kinesthetic only, cutaneous only and combined sensory feedback. The cutaneous feedback was capable of displaying the local surface orientation at the contact point, through a small plate indenting the fingerpad at contact. A psychophysics test was conducted with SDT methodology on 6 subjects to assess the discrimination threshold of angle perception between two parallel surfaces, with three sensory modalities and two shape sizes. Results show that the cutaneous sensor modality is not affected by size of shape, but kinesthetic performance is decreasing with smaller size. Cutaneous and kinesthetic sensory cues are integrated according to a Bayesian model, so that the combined sensory stimulation always performs better than single modalities alone.

2008-01-01

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

The challenge of establishing treatment efficacy for cutaneous vascular manifestations of systemic sclerosis.

Science.gov (United States)

Pauling, John D

2018-05-01

The cutaneous vascular manifestations of systemic sclerosis (SSc) comprise Raynaud's phenomenon, cutaneous ulceration, telangiectasia formation and critical digital ischaemia; each of which are associated with significant disease-related morbidity. Despite the availability of multiple classes of vasodilator therapy, many of which have been the subject of RCTs, a limited number of pharmacological interventions are currently approved for the management of cutaneous vascular manifestations of SSc. Areas covered: A major challenge has been demonstrating treatment efficacy with examples of promising therapies yielding contrasting results in controlled trial settings. Differences between consensus best-practice guidelines, evidence-based recommendations and marketing approvals in different jurisdictions has resulted in geographic variation in clinical practice concerning the management of cutaneous vascular manifestations of SSc. Difficulty demonstrating treatment efficacy risks waning industry engagement for drug development programmes in this field. This article highlights the key challenges in establishing treatment efficacy and barriers that must be overcome to support successful clinical trial programmes across the spectrum of cutaneous vascular manifestations of SSc. Expert commentary: The paucity of approved treatments for cutaneous vascular manifestations of SSc relates as much to challenges in clinical trial design and the need for reliable clinical trial endpoints, as to lack of therapeutic options.

Multiple cutaneous malignancies in a patient of xeroderma pigmentosum.

Science.gov (United States)

Grampurohit, Vandana U; Dinesh, U S; Rao, Ravikala

2011-01-01

Xeroderma pigmentosum is a genodermatosis characterized by photosensitivity and the development of cutaneous and internal malignancies at an early age. The basic defect underlying the clinical manifestations is a nucleotide excision repair defect, leading to defective repair of DNA damaged by ultraviolet radiation. These patients exhibit enhanced sensitivity to ionizing radiation. Patients with xeroderma pigmentosum who are younger than 20 years of age have a greater than 1000-fold increased risk of developing skin cancer. Early detection of these malignancies is necessary because they are fast growing, metastasize early and lead to death. Although, early detection and treatment of cutaneous malignancies will reduce the morbidity and mortality, genetic counseling remains the most important measure for preventing xeroderma pigmentosum. We report a case of xeroderma pigmentosum in an 18-year-old male presenting with multiple cutaneous malignancies: squamous cell carcinoma, malignant melanoma and pigmented basal cell carcinoma.

Kinjal Deepak Rambhia

2016-01-01

Full Text Available Cutaneous collagenous vasculopathy (CCV is a distinct, rare, and underdiagnosed condition. We report a case of CCV in a 50-year-old woman presenting as asymptomatic, erythematous to hyperpigmented nonblanchable macules over both the lower extremities. The clinical differential diagnosis of the lesions was pigmented purpuric dermatoses (Schamberg's purpura and cutaneous small vessel vasculitis. Histology of the lesions revealed dilated superficial dermal vessels with abundant pink hyaline material in the vessel wall, which stained with periodic acid Schiff stain. The patient was diagnosed as CCV. This condition remains largely underdiagnosed and is commonly mistaken for pigmented purpuric dermatosis or generalized essential telangiectasia. Emphasis on the differentiation of CCV from its clinical and histological mimicks is made.

2017-03-01

Locally advanced colon cancer with direct abdominal wall and skin invasion is an extremely rare finding with most data being derived from case reports, historical autopsy-based or single-center retrospective studies. We present a unique case of a colon cancer with direct cutaneous invasion and colocutaneous fistulization. Eighty-six year old Caucasian female with multiple comorbidities, referred to Surgical Consultation due to ulcerated skin lesion in the abdomen. She had a long-standing large umbilical hernia but with no previous episodes of incarceration or occlusive symptoms. She denied any digestive or constitutional symptoms. Physical examination showed a large non-reducible umbilical hernia, with an associated painless firm mass within the hernia sac and cutaneous ulcerated growth. Colonoscopy revealed transverse colon cancer (endoscopic biopsy of the tumor and skin punch biopsy confirmed adenocarcinoma of the colon). Computed tomography showed a tumoral mass within the umbilical hernia, with cutaneous infiltration and enlarged regional lymph nodes. Rapid local progression led to colocutaneous fistula with total fecal diversion. We performed an extended right hemicolectomy with en bloc excision of the hernia sac and infiltrating cutaneous mass. In the current era of widespread use of screening colonoscopies, initial diagnosis of locally advanced colon cancer is decreasing. However, this unique case presented an opportunity to recall the advantages of multivisceral resections.

[Cutaneous adverse reactions to tattoos and piercings].

Science.gov (United States)

Mataix, J; Silvestre, J F

2009-10-01

Piercings and tattoos have become very popular in western society in recent decades, particularly among younger generations. Reports of medical complications associated with these decorative techniques have increased in parallel with the rise in their popularity. Due to their high frequency, adverse cutaneous reactions are particularly important among these potential complications. Tattoo-related complications include a number of cutaneous and systemic infections secondary to breach of the epidermal barrier, acute and delayed inflammatory reactions with different histopathological patterns, the appearance of benign and malignant tumors on tattooed areas of skin, and certain dermatoses triggered by isomorphic phenomena. Piercing-related complications are similar, though some, such as pyogenic skin infections, are much more common due to the delayed wound healing after piercing in certain sites. We must differentiate between complications that are independent of the site of piercing, and specific complications, which are closely related to the body area pierced. The rate of complications after performing piercings or tattoos depends on the experience of the artist, the hygiene techniques applied, and the postprocedural care by the customer. However, some of these complications are unpredictable and depend on factors intrinsic to the patient. In this article, we review the most common decorative techniques of body art, with particular focus on the potential cutaneous complications and their management.

Ekwealor, Chito Clare; Oyeka, Christie Amechi

2013-01-01

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 col...

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.

On a Rare Cutaneous Metastasis from a Sacrococcygeal Chordoma

Full Text Available Chordomas are rare malignant tumors of notochordal origin and are rare locally aggressive ones with a metastatic potential. The skin rarely is seen as metastatic site. We describe a case of an adult woman with cutaneous metastasis of a primary sacral chordoma excised ten years before, which appeared as a painless cutaneous mass located in the dorsal region. Once removed, the surgical specimen was formalin fixed and in paraffin embedded. Sections were stained with haematoxylin-eosin, and histochemical and immunohistochemical investigations were performed. Histologically, the neoplasia was characterized by cords or single tumor cells with an abundant myxoid stroma, conspicuous pale vacuolated cytoplasm (the classic “physaliphorous cells”, and mild nuclear atypia. Mitotic activity was scanty. At immunohistochemistry, the tumor cells were diffusely positive for S-100 protein, pan-keratins, EMA, and vimentin. A diagnosis of cutaneous metastasis of chordoma was performed. This case illustrates a diagnostic challenge because of the unusual presentation of an already rare tumor.

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

2012-01-01

We lack non-invasive tools for evaluating the coronary and renal microcirculations. Since cutaneous Doppler laser exploration has evidenced impaired cutaneous microvascular responses in coronary artery disease and in impaired renal function, we wanted to find out if there was a link between the impairments in the cutaneous and renal microcirculations. To specify the significance of the rise in the renal resistive index (RI), which is still unclear, we also sought relations between RI and arterial stiffness. We conducted a cross-sectional controlled study in a heterogeneous population including hypertensive patients of various ages with or without a history of cardiovascular disease along with a healthy control group. The cutaneous microcirculation was evaluated by laser Doppler flowmetry of the post-occlusive reactive hyperhemy (PORH) and of the hyperhemy to heat. The renal microcirculation was evaluated by measurement of the RI. Arterial stiffness was evaluated from an ambulatory measurement of the corrected QKD(100-60) interval. We included 22 hypertensives and 11 controls of mean age 60.6 vs 40.8 years. In this population, there was a correlation between RI and basal zero to peak flow variation (BZ-PF) (r=-0.42; P=0.02) and a correlation between RI and rest flow to peak flow variation (RF-PF) (r=-0.44; P=0.01). There was also a significant correlation between RI and the corrected QKD(100-60) (r=-0.47; P=0.01). The significant correlation between PORH parameters and RI indicates that the functional modifications of the renal and cutaneous microcirculations tend to evolve in parallel during ageing or hypertension. The relation between RI and arterial stiffness shows that RI is a compound index of both renal microvascular impairment and the deterioration of macrovascular mechanics.

Histomorphological and immunohistochemical characterization of 172 cutaneous round cell tumours in dogs

Marina Rios Araújo

2012-08-01

Full Text Available This paper describes the use of a panel of antibodies (CD117, CD3, CD79a, CD45, cytokeratin, vimentin and E-cadherin on formalin-fixed, paraffin-embedded sections of canine cutaneous round cell tumours. Neoplastic tumours were diagnosed by histology and histochemical stains and included 107 mast cell tumours, 31 cutaneous histiocytomas, two localized histiocytic sarcomas, 21 cutaneous lymphomas, three plasma cell tumours, one transmissible venereal tumour and seven unclassified round cell tumours. The histologic diagnosis was modified in 39.5% of the total 172 neoplasms. The staining for CD45 and Ecadherin were variable, and therefore, the final diagnoses of cutaneous histiocytoma and localized histiocytic sarcoma were made based on histology in association with negative results for CD3, CD79a, CD117 and cytokeratin. The cellular origin of unclassified round cell tumours was defined in all cases. Cutaneous B-cell lymphoma and plasma cell tumours were CD79a-positive and could be distinguished from each other by the morphological characteristics. Mast cell tumours and T cell lymphoma were CD117 and CD3 positive, respectively. The positive staining for vimentin and the negative staining for CD3, CD79a, CD117 and cytokeratin favoured the diagnosis of transmissible venereal tumours. Thus, the final diagnosis of cutaneous round cell tumours should be based on the interpretation of immunohistochemical results together with the cellular morphology observed by histology. Therefore, more studies to optimize the specific markers in formalin-fixed, paraffinembedded tissues (especially for histiocytes are required for definitive diagnosis of round cell tumours in dogs.

Full Text Available Cutaneous T cell lymphomas (CTCLs are a heterogeneous group of extranodal non-Hodgkin’s lymphomas that are characterized by a cutaneous infiltration of malignant monoclonal T lymphocytes. They typically afflict adults with a median age of 55 to 60 years, and the annual incidence is about 0.5 per 100,000. Mycosis fungoides, Sézary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified are the most important subtypes of CTCL. CTCL is a complicated concept in terms of etiopathogenesis, diagnosis, therapy, and prognosis. Herein, we summarize advances which have been achieved in these fields.

Mastocytosis represents a group of diseases characterised by an excesive accumulation of mastocytes in one or multiple tissues. It can affect only the skin, or have a systemic involvement. It has a low prevalence, and the prognosis is benign in children. To report a case of urticaria pigmentosa as a subtype of cutaneous mastocytosis, and present a literature review focused on clinical findings, diagnosis and initial basic management. A child of six months of age presenting with multiple blemishes and light brown papules located on the trunk, arms and legs. The symptoms were compatible with urticaria pigmentosa, and was confirmed by biopsy. Tests to rule out systemic involvement were requested. The patient was treated with general measures, education, and antihistamines, with favourable results. Cutaneous mastocytosis is a rare disease with a good prognosis. In childhood general measures and education are usually enough to obtain favourable results. Histamine H1 antagonists are the first line drug treatment.

2012-02-01

Cutaneous nocardiosis is a rare infection that may manifest as a superficial skin lesion, lymphocutaneous infection, mycetoma, or diffuse cutaneous infection from a disseminated systemic infection. We report a case of a 65-year-old immunocompromised man with persistent primary cutaneous Nocardia brasiliensis infection following a motor vehicle collision. A high degree of suspicion is needed to diagnose Nocardia infection because of its resemblance to other bacterial infections. Nocardiosis should be included in the differential diagnosis of chronic cutaneous infections, especially when the response to antibiotics is inadequate or when the patient is immunocompromised. Because Nocardia may take several weeks to grow in standard bacterial culture media, laboratories should be notified of the suspicion so that culture plates are held for longer time periods. Long-term therapy, usually with sulfonamides, often is necessary.

Cutaneous Cancers in Nigerian Albinos: A Review of 22 Cases

Directory of Open Access Journals (Sweden)

Oluwafemi Olasupo Awe

2018-01-01

Full Text Available Context: Albinism is an inherited disorder of hypopigmentation involving the skin, eyes, and hair. This disorder results in the absence or reduction in melanin production. There are two main types of albinism which are ocular albinism and oculocutaneous albinism. It could also be classified as syndromic or nonsyndromic the melanin, which protects from the harmful effect of ultraviolet radiation of the sun on the normal skin, is deficient in the albino, predisposing them more, to cutaneous malignancies. Aim: This study is to highlight the epidemiology of cutaneous cancers in albinos in sub-urban Nigeria. Methodology: This is a retrospective review of all albinos with histological diagnoses of cutaneous malignancies that presented to Irrua Specialist Teaching Hospital, Irrua Edo State, Nigeria between September 2010 and August 2016. The following details were extracted from the patients' case-notes, operation register, and the histopathology register. These data include age, gender, site of the lesion, the diagnosis, no of lesions excised, and duration of the lesion (s. These were collated and analyzed using SPSS version 22. Results: There were 22 albinos with histopathologically diagnosed cutaneous malignancies. There were 11 males and 11 females with male:female of 1. The age range is from 25 to 55 years with the mean of 34.68. Conclusion: Albinism is one of the most common causes of cutaneous malignancies, and majority of them present with locally advanced lesions that will need excision biopsy resulting in disfigurement. This problem can be prevented in many cases with proper community education, support, and free health care. There is also need for them to present early whenever they noticed any skin changes.

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. 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. 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 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. 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.

Giant cutaneous horn in an African woman: a case report

Directory of Open Access Journals (Sweden)

Nthumba Peter M

2007-12-01

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.

Cutaneous and systemic hypersensitivity reactions to metallic implants.

Science.gov (United States)

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

2011-01-01

Cutaneous reactions to metal implants, orthopedic or otherwise, are well documented in the literature. The first case of a dermatitis reaction over a stainless steel fracture plate was described in 1966. Most skin reactions are eczematous and allergic in nature, although urticarial, bullous, and vasculitic eruptions may occur. Also, more complex immune reactions may develop around the implants, resulting in pain, inflammation, and loosening. Nickel, cobalt, and chromium are the three most common metals that elicit both cutaneous and extracutaneous allergic reactions from chronic internal exposure. However, other metal ions as well as bone cement components can cause such hypersensitivity reactions. To complicate things, patients may also develop delayed-type hypersensitivity reactions to metals (ie, in-stent restenosis, prosthesis loosening, inflammation, pain, or allergic contact dermatitis) following the insertion of intravascular stents, dental implants, cardiac pacemakers, or implanted gynecologic devices. Despite repeated attempts by researchers and clinicians to further understand this difficult area of medicine, the association between metal sensitivity and cutaneous allergic reactions remains to be fully understood. This review provides an update of the current knowledge in this field and should be valuable to health care providers who manage patients with conditions related to this field.

In nodal diffuse large B-cell lymphoma, the search for double-hit with MYC and BCL2 and/or BCL6 rearrangements or for dual expression of BCL2 and MYC defines subgroups of patients with altered prognosis that has not been evaluated in primary cutaneous large B-cell lymphoma. Our objectives were to assess the double-hit and dual expressor status in a cohort of 44 patients with primary cutaneous large B-cell lymphoma according to the histological subtype and to evaluate their prognosis relevance. The 44 cases defined by the presence of more than 80% of large B-cells in the dermis corresponded to 21 primary cutaneous follicle centre lymphoma with large cell morphology and 23 primary cutaneous diffuse large B-cell lymphoma, leg type. Thirty-one cases (70%) expressed BCL2 and 29 (66%) expressed MYC. Dual expressor profile was observed in 25 cases (57%) of either subtypes (n = 6 or n = 19, respectively). Only one primary cutaneous follicle centre lymphoma, large-cell case had a double-hit status (2%). Specific survival was significantly worse in primary cutaneous diffuse large B-cell lymphoma, leg type than in primary cutaneous follicle centre lymphoma, large cell (p = 0.021) and for the dual expressor primary cutaneous large B-cell lymphoma group (p = 0.030). Both overall survival and specific survival were worse for patients belonging to the dual expressor primary cutaneous diffuse large B-cell lymphoma, leg type subgroup (p = 0.001 and p = 0.046, respectively). Expression of either MYC and/or BCL2 negatively impacted overall survival (p = 0.017 and p = 0.018 respectively). As the differential diagnosis between primary cutaneous follicle centre lymphoma, large cell and primary cutaneous diffuse large B-cell lymphoma, leg type has a major impact on prognosis, dual-expression of BCL2 and MYC may represent a new diagnostic criterion for primary cutaneous diffuse large B-cell lymphoma, leg type subtype and further identifies patients with

The drugs most often incriminated for the various cutaneous ADR were antimicrobials (42.6%, anticonvulsants (22.2% and NSAIDs (18%. Anticonvulsants were implicated in 41.6% of maculopapular rashes. Sulfonamides accounted for 43.3% and NSAIDs for 30.7% of FDE. Urticaria was caused mainly by NSAIDs(24.3% and penicillins(20%. Anticonvulsants were responsible for 43.8% of life-threatening toxic epidermal necrolysis and Stevens Johnson syndrome. CONCLUSIONS: The clinical pattern and drugs causing cutaneous ADR are similar to those observed in other countries except for minor variations. Cutaneous ADR patterns and the drugs causing various reactions are changing every year, which may be due to the emergence of newer molecules and changing trends in the use of drugs.

Cutaneous zygomycosis: A possible postoperative complication in immunocompetent individuals

Directory of Open Access Journals (Sweden)

Tilak Ragini

2009-01-01

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

Science.gov (United States)

Kinio, Anna E; Sawchuk, Michael A; Pratt, Melanie

Rosai Dorfman disease (RDD) is a rare disorder that typically presents with bilateral cervical lymphadenopathy and follows a benign course. We present a case of late-onset atypical primary cutaneous RDD that is resistant to treatment modalities described in the literature. Case report. An 84-year-old woman presented with a 7-year history of cutaneous lesions histologically consistent with RDD. She later failed initial treatments of acitretin and thalidomide. Physicians must be aware of unusual presentations of RDD. Also, further treatment options must be explored for patients resistant to classical management of RDD.

2016-01-01

Intralesional treatment for cutaneous leishmaniasis has been applied for over 30 years at the Oswaldo Cruz Foundation, Rio de Janeiro, with good therapeutic results and without relevant systemic toxicity. Meglumine antimoniate was injected subcutaneously, using a long medium-caliber needle (for example, 30mm × 0.8mm); patients received 1-3 injections, with 15-day intervals. The technique is described in detail sufficient to enable replication. The treatment of cutaneous leishmaniasis with intralesional meglumine antimoniate is a simple, effective, and safe technique, which may be used in basic healthcare settings.

Margaret Taghavi

2014-10-01

Full Text Available Background: Primary cutaneous B-cell lymphoma typically localizes to the skin, and dissemination to internal organs is rare. Lymphomatous involvement of the breasts is also rare. We describe the clinical and radiological findings of an unusual case of primary cutaneous B-cell lymphoma presenting as an isolated breast mass without associated skin changes. Case Presentation: The patient was a 55-year-old Caucasian female who initially presented with cutaneous B-cell lymphoma around her eyes and forehead with recurrence involving the skin between her breasts. Three years after terminating treatment due to a lack of symptoms, she presented for an annual screening mammogram that found a new mass in her upper inner right breast without imaging signs of cutaneous extension. On physical examination, there were no corresponding skin findings. Due to the suspicious imaging features of the mass that caused concern for primary breast malignancy, she underwent a core biopsy which revealed cutaneous B-cell lymphoma. Conclusion: When evaluating patients with a systemic disease who present with findings atypical for that process, it is important to still consider the systemic disease as a potential etiology, particularly with lymphoma given its reputation as a great mimicker.

Edelglass, J W; Douglass, M C; Stiefler, R; Tessler, M

1982-09-01

Three young women recently returned to the metropolitan Detroit area with cutaneous larva migrans. All three had vacationed at a popular club resort on the Caribbean island of Martinique. Cutaneous larva migrans is frequently seen in the southern United States, Central and South America, and other subtropical areas but rarely in northern climates. Several organisms can cause cutaneous larva migrans, or creeping eruption. The larvae of the nematode Ancylostoma braziliense are most often the causative organisms. Travel habits of Americans make it necessary for practitioners in northern climates to be familiar with diseases contracted primarily in warmer locations. The life cycle of causative organisms and current therapy are reviewed.

Full Text Available Jitlada Meephansan,1 Atiya Rungjang,1 Werayut Yingmema,2 Raksawan Deenonpoe,3 Saranyoo Ponnikorn3 1Division of Dermatology, Chulabhorn International College of Medicine, Thammasat University, Pathum Thani, Thailand; 2Laboratory Animal Centers, Thammasat University, Pathum Thani, Thailand; 3Chulabhorn International College of Medicine, Thammasat University, Pathum Thani, Thailand Abstract: Wound healing consists of a complex series of convoluted processes which involve renewal of the skin after injury. ROS are involved in all phases of wound healing. A balance between oxidative and antioxidative forces is necessary for a favorable healing outcome. Astaxanthin, a member of the xanthophyll group, is considered a powerful antioxidant. In this study, we investigated the effect of topical astaxanthin on cutaneous wound healing. Full-thickness dermal wounds were created in 36 healthy female mice, which were divided into a control group and a group receiving 78.9 µM topical astaxanthin treatment twice daily for 15 days. Astaxanthin-treated wounds showed noticeable contraction by day 3 of treatment and complete wound closure by day 9, whereas the wounds of control mice revealed only partial epithelialization and still carried scabs. Wound healing biological markers including Col1A1 and bFGF were significantly increased in the astaxanthin-treated group since day 1. Interestingly, the oxidative stress marker iNOS showed a significantly lower expression in the study. The results indicate that astaxanthin is an effective compound for accelerating wound healing.

Treatment of Cutaneous Pseudolymphoma: A Systematic Review

Directory of Open Access Journals (Sweden)

Diana Miguel

2017-12-01

Full Text Available Cutaneous pseudolymphoma (CPL is a reactive polyclonal T- or B-cell lymphoproliferative process. CPL may appear as localized or disseminated skin lesions. While most cases of CPL are idiopathic, they may also occur as a response to, for example, contact dermatitis, arthropod reactions, and bacterial infections. CPL can be classified based on its clinical features, but all variants have similar histopathological patterns of either predominantly B-cell infiltrates, T-cell infiltrates, or mixed T/B-cell infiltrates. The prognosis of CPL is good, but the underlying disease process should be taken into account. If an antigenic stimulus is identified, it should be removed. In patients with idiopathic CPL, a close follow-up control strategy should be adopted. The aim of this systematic review is to summarize all reported treatments for CPL. The review was based on articles from the PubMed database, using the query “skin pseudolymphoma treatment”, English and German, about “human” subjects, and published between 1990 and 2015 documenting adequate treatment and/or aetiology. Mainly individual case reports and small case series were found. Treatment options include topical and intralesional agents, systemic agents, and physical modalities. The final part of the review proposes a treatment algorithm for CPL according to each aetiology, based on the literature of the last 25 years. Future research should focus on randomized controlled trials and studies on long-term outcomes, which were not identified in the current review.

Infant and young child skin diseases are among the most common features of morbidity throughout the tropics. Because the skin is directly exposed to the environment, it is considerably affected by climatic and local conditions such as vectors and microorganisms, as in the case of leishmaniasis. In America the observed magnitude of cutaneous leishmaniasis in children has led to the study of increased risk of exposure of this group due to the possibility of peri- and intradomiciliary transmission. The present review pretends to make a concrete approach all through the broad and main figures of this parasitic disease, including the clinical, physiopathological, epidemiological, diagnostic, and therapeutic aspects, in order to be used as a practical source of reference for pediatricians leading with tropical cutaneous pathology in the region. © 2017 The International Society of Dermatology.

A Rare Case of Zosteriform Cutaneous Metastasis from Breast Cancer

Directory of Open Access Journals (Sweden)

2017-03-01

Full Text Available Breast cancer is the most common cancer among women and the second leading cause of cancer deaths, after lung cancer. Cutaneous breast cancer metastases often develop as direct involvement and local spread and often manifest as solid painless nodules in the anterior chest wall. Internal malignant skin metastases rarely present like soft nodules, telangiectasia-like lesions, neoplastic alopecia, erysipeloides carcinoma, erythema annulare-like, herpetiformis or zosteriform, target-like, pyodermic and morphea-like lesions. In this article, we present a 49-year-old female patient describing a sensation of burning pain with erythematous papules and plaques in a zosteriform distribution. The diagnosis of zosteriform cutaneous metastases from a breast cancer was made. Majority of these cases may be misdiagnosed as herpes zoster infection and can be treated with antiviral drugs. Therefore, cutaneous metastases should be kept in mind in the differential diagnosis of lesions in zosteriform distribution.

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 emotions" and "global" scores of 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.

Simultaneous Disruption of Mouse ASIC1a, ASIC2 and ASIC3 Genes Enhances Cutaneous Mechanosensitivity

Kang, Sinyoung; Jang, Jun Ho; Price, Margaret P.; Gautam, Mamta; Benson, Christopher J.; Gong, Huiyu; Welsh, Michael J.; Brennan, Timothy J.

2012-01-01

Three observations have suggested that acid-sensing ion channels (ASICs) might be mammalian cutaneous mechanoreceptors; they are structurally related to Caenorhabditis elegans mechanoreceptors, they are localized in specialized cutaneous mechanosensory structures, and mechanical displacement generates an ASIC-dependent depolarization in some neurons. However, previous studies of mice bearing a single disrupted ASIC gene showed only subtle or no alterations in cutaneous mechanosensitivity. Because functional redundancy of ASIC subunits might explain limited phenotypic alterations, we hypothesized that disrupting multiple ASIC genes would markedly impair cutaneous mechanosensation. We found the opposite. In behavioral studies, mice with simultaneous disruptions of ASIC1a, -2 and -3 genes (triple-knockouts, TKOs) showed increased paw withdrawal frequencies when mechanically stimulated with von Frey filaments. Moreover, in single-fiber nerve recordings of cutaneous afferents, mechanical stimulation generated enhanced activity in A-mechanonociceptors of ASIC TKOs compared to wild-type mice. Responses of all other fiber types did not differ between the two genotypes. These data indicate that ASIC subunits influence cutaneous mechanosensitivity. However, it is unlikely that ASICs directly transduce mechanical stimuli. We speculate that physical and/or functional association of ASICs with other components of the mechanosensory transduction apparatus contributes to normal cutaneous mechanosensation. PMID:22506072

Cryptococcal meningitis with secondary cutaneous involvement in an immunocompetent host.

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

CD30 primary cutaneous lymphoproliferative diseases include both lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large cell lymphoma (PCALCL). The neoplastic cell of most primary CD30 lymphoproliferative disorders is CD4 positive. The terminology LyP "type D" has been used to describe a growing number of cases of LyP with a predominantly CD8 infiltrate. PCALCL with a CD8 phenotype has also been described, which presents a particularly difficult diagnostic and management challenge, given the difficulty in distinguishing it histologically from other cytotoxic lymphomas such as primary cutaneous aggressive epidermotropic CD8 cytotoxic T-cell lymphoma and CD8 gamma/delta and natural killer/T-cell lymphoma. We report 7 additional cases of these rare cutaneous CD8/CD30 lymphoproliferative disorders. We also present a unique case of CD8/CD30 LyP with histologic similarities to LyP type B. In all 7 of our cases of CD8 LyP and CD8 anaplastic large cell lymphoma, we found focal to diffuse MUM-1 positivity. We propose that MUM-1 may represent an adjunctive marker for CD8 lymphoproliferative disease. Finally, we review the current literature on cases of CD8 LyP and PCALCL. For the 106 cases examined, we found similar clinical and histologic features to those reported for traditional CD4CD30 LyP and PCALCL.

Local increase of arginase activity in lesions of patients with cutaneous leishmaniasis in Ethiopia.

Directory of Open Access Journals (Sweden)

Tamrat Abebe

Full Text Available Cutaneous leishmaniasis is a vector-borne disease that is in Ethiopia mainly caused by the parasite Leishmania aethiopica. This neglected tropical disease is common in rural areas and causes serious morbidity. Persistent nonhealing cutaneous leishmaniasis has been associated with poor T cell mediated responses; however, the underlying mechanisms are not well understood.We have recently shown in an experimental model of cutaneous leishmaniasis that arginase-induced L-arginine metabolism suppresses antigen-specific T cell responses at the site of pathology, but not in the periphery. To test whether these results translate to human disease, we recruited patients presenting with localized lesions of cutaneous leishmaniasis and assessed the levels of arginase activity in cells isolated from peripheral blood and from skin biopsies. Arginase activity was similar in peripheral blood mononuclear cells (PBMCs from patients and healthy controls. In sharp contrast, arginase activity was significantly increased in lesion biopsies of patients with localized cutaneous leishmaniasis as compared with controls. Furthermore, we found that the expression levels of CD3ζ, CD4 and CD8 molecules were considerably lower at the site of pathology as compared to those observed in paired PBMCs.Our results suggest that increased arginase in lesions of patients with cutaneous leishmaniasis might play a role in the pathogenesis of the disease by impairing T cell effector functions.

Methotrexate-induced nonhealing cutaneous ulcers in a nonpsoriatic patient without pancytopenia

Full Text Available Methotrexate forms one of the main drugs in the pharmacological management of rheumatoid arthritis, psoriasis, and some neoplastic diseases. Methotrexate rarely causes cutaneous ulceration and most cases are reported in patients with psoriasis and have been accompanied by pancytopenia. The author here reports occurrence of multiple (two cutaneous ulcers due to methotrexate in a nonpsoriatic patient. The patient was on methotrexate for seronegative rheumatoid arthritis for 10 years. To the best of the Author's knowledge, this is a rare case of cutaneous ulceration due to methotrexate in a nonpsoriatic patient reported in the literature so far, and probably one of its kind without pancytopenia or other hematological abnormalities. Stopping this medication led to complete healing of the ulcerated lesion in about four to six weeks.

Unexpected cutaneous reactions in diabetic and pre diabetic patients treated with salsalate

International Nuclear Information System (INIS)

Adibi, N.; Faghihimani, E.; Mirbagher, L.; Sohrabi, H.; Toghiani, A.

2012-01-01

Objective: The most commonly reported side effects of salsalate are gastrointestinal events, and few reports are available on its cutaneous side effects. We therefore assessed cutaneous side effects among diabetic/pre-diabetic patients treated with salsalate. Methodology: In a randomized placebo-controlled trial, we evaluated cutaneous side effects in 52 diabetic and 124 pre-diabetic patients, 90 of whom received 3 g/day salsalate and 86 of whom receive a placebo for four weeks. The evaluation was carried out every week using a checklist completed by a single general practitioner. Results: The difference between the salsalate- and placebo-treated groups in overall prevalence of cutaneous reactions was not significant (26.7% versus 17.4%; P < 0.05). Side effects included urticaria (nine (10.1%) salsalate-treated versus six (6.9%) placebo-treated), rashes (five (5.5%) salsalate-treated versus three (3.4%) placebo-treated), pruritus (six (6.7%) salsalate-treated versus three (3.4%) placebo-treated), and edema (two (2.2%) salsalate-treated versus one (1.2%) placebo-treated); in addition, one (1.1%) case of erythema nodosum and one (1.1%) of vasculitis were observed in the salsalate-treated group. In the salsalate group, therapy was discontinued by the physician for three (3.3%) patients because of acute and severe vasculitis, erythema nodosum and urticaria and two (2.2%) patients stopped the treatment themselves because of mild urticaria compared with two patients who stopped using the placebo. Conclusions: Salsalate can cause several and, in some cases, severe cutaneous side effects in patients with diabetes/pre-diabetes. Because these cutaneous eruptions can raise various concerns, including patient non-compliance, greater attention should be paid to dermatological problems in patients under salsalate treatment.

In most of the empirical literature on land titling, the household is regarded as unitary, and land rights are found to have ambiguous effects on land allocation, investment and productivity. Using data from 12 provinces in Vietnam, we diversify land titles, and show in a household fixed effects...... analysis of plot level rice yields that land titles are indeed important. Only exclusively held titles have the expected positive effects, and the positive effect on yields is found in male headed households. Furthermore, a household level rice yield function reveals that exclusive user rights...... are inefficiency decreasing, while jointly held user rights have no efficiency effects. Finally, once the gender of the head of household is controlled for, exclusively held female titles have a greater positive effect on the efficiency of the household than that of male held titles...

All twelve Beagle dogs undergoing long-term therapy (26 weeks) with the immunosuppressive drug cyclosporine-A (30 mg/kg), developed cutaneous papillomatous hyperplasia. By week 7 all dogs developed generalized lesions distributed over the entire body. These occurred as irregular, oval, sessile, unpigmented, firm masses. The incidence and severity of the skin lesions varied among dogs and anatomic site, with no correlation to the blood level of cyclosporine. Microscopic analysis revealed that the epidermis formed short papillary folds on broad fibrovascular stalks and was hyperkeratotic and acanthotic. Mild hyperplasia of hair follicles and sebaceous glands was also evident. A mild diffuse infiltrate of lymphocytes and plasma cells was present in the papillary dermis. No histopathologic changes typical of papillomavirus infection were identified, nor were papillomavirus group-specific antigens or viral DNA detected. Other cutaneous side effects included hyperkeratosis of footpads, increased growth of hair and nails, and hyperkeratinization of the haired skin of the prepuce. All cutaneous lesions regressed spontaneously within 8 weeks following termination of cyclosporine administration. The hyperplastic lesions may have resulted from the action of cyclosporine via the T-lymphocyte system. Conversely a direct action of this drug on epithelial cells may have stimulated proliferation and keratinization.

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.

The cutaneous wound repair process involves balancing a dynamic series of events ranging from inflammation, oxidative stress, cell migration, proliferation, survival and differentiation. A complex series of secreted trophic factors, cytokines, surface and intracellular proteins are expressed in a temporospatial manner to restore skin integrity after wounding. Impaired initiation, maintenance or termination of the tissue repair processes can lead to perturbed healing, necrosis, fibrosis or even cancer. Nuclear hormone receptors (NHRs) in the cutaneous environment regulate tissue repair processes such as fibroplasia and angiogenesis. Defects in functional NHRs and their ligands are associated with the clinical phenotypes of chronic non-healing wounds and skin endocrine disorders. The functional relationship between NHRs and skin niche cells such as epidermal keratinocytes and dermal fibroblasts is pivotal for successful wound closure and permanent repair. The aim of this review is to delineate the cutaneous effects and cross-talk of various nuclear receptors upon injury towards functional tissue restoration. Copyright © 2014 John Wiley & Sons, Ltd.

Measurement in vivo of the cutaneous contamination provoked by a radioactive solution

The utilization of unsealed radioactive sources may cause cutaneous contamination accidents. The detriment is function of the dose of irradiation absorbed by the basal layer of the epidermis and mainly depends on the energy of the β rays, the molecular nature of contaminant and the time of contact with the skin. Furthermore, the penetration kinetic of a substance through the skin is influenced by different factors. So as to determine the dose of irradiation absorbed by the basal layer of the epidermis, we have realized different studies of cutaneous contamination in vivo in the pig: in a first study wa have compared cutaneous obsorption of a radioisotope ( 99m TC) diluted in physiological serum, in a aprotic solvent (DMSO) known to enhance the cutaneous permeability, and by varying the pH of the solution. In a second part, we have compared the cutaneous absorption after contamination times of 1 and 5 minutes, and in different hydration states of the skin before contamination. Results of the in vivo cutaneous absorption, for contaminating times of 1 and 5 minutes, have shown a loss of 5 % of external counting of the electrons (external counting of the 120 KeV electron of 99m Tc), one hour after the contamination, for all the chemical vectors. The variation of the contamination time and the state of hydration of the skin before contamination showed similar results. From these experimental results, an exponential distribution model of the radioisotope in the skin has allowed to calculate the dose rate equivalent of irradiation absorbed by the basal layer of the ipidermis: during a contamination of 5 minutes on a surface of 9 cm 2 with 99m Tc, this dose rate equivalent was 0.98 mSv h -1 by 37 kBq cm -2 (μCi cm -2 ). By the Monte-Carlo method in the hypothesis where there is no cutaneous absorption, it was 0.94 mSv h -1 by 37 kBq cm-2. A preliminary experience with a β emitter ( 14 C) has confirmed a less of 5% of the counting in the same experimental conditions

The present studies were undertaken to quantitate the initial inflammatory response produced by the photo-generated reactive species in rabbit skin. Rose bengal (RB), a photosensitizer dye, was injected into the skin sites at various concentrations and exposed to UV-visible light for 30-120 min. The increase in vascular permeability and the accumulation of PMNs were investigated using 125I-labeled albumin and 51Cr-labeled PMNs. RB at a concentration of 1 nmol with 120-min exposure to light enhanced vascular permeability by 3.7 times and accumulation of PMNs by 3.3 times. As low as 0.01 nmol of RB produced discernible effects. beta-Carotene (0.1 nmole) inhibited the inflammatory response by 75-100%, suggesting that the reactive species involved in this response was predominantly singlet oxygen. The increase in vascular permeability was inhibited by 48-70% by 25 micrograms of chlorpheniramine maleate. It is therefore suggested that histamine plays a major role in the initial vascular response. The studies demonstrate that this rabbit model is suitable for the quantitation of photoinduced inflammatory response which is not observable by gross anatomic procedures

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

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

Full Text Available Background: Thyroid disorders are known to involve all the organ systems of the body, the skin being no exception. The association of thyroid disorders with cutaneous manifestations is complex. Both hypothyroidism and hyperthyroidism are known to cause these changes. Aims: The present study was designed to ascertain the varied cutaneous manifestations of hypothyroidism. Materials and Methods: This study was a hospital based clinical study conducted in collaboration with the Endocrinology Division (Department of Medicine of SMHS Hospital (associated teaching hospital of Government Medical College Srinagar, over a period of one year, from May 2010 to May 2011. Four hundred and sixty consecutive diagnosed cases of hypothyroidism constituted the subject material for the study and were evaluated for the presence of any cutaneous manifestation. Results: In our study group of 460 patients, there were 416 females and 44 male patients. The predominant cutaneous symptom in our hypothyroid patients was dry coarse skin (65.22%, followed by hair loss (42.6% and puffy edema (38.48%. The most common cutaneous sign observed in hypothyroid patients was xerosis (57.17%, followed by diffuse hair loss (46.09%, altered skin texture (31.74%, coarse scalp hair (29.35% and puffy face (28.69%. Conclusions: The interaction between thyroid gland and skin is of profound clinical importance in dermatological practice. So, dermatologists need to be cognizant of the ways in which these two organs interact.

Multiple chemical sensitivity (MCS) is characterised by adverse effects due to exposure to low levels of chemical substances. The aetiology is unknown, but chemical related respiratory symptoms have been found associated with positive patch test. The purpose of this study was to investigate the relationship between cutaneous reactions from patch testing and self-reported severity of chemical sensitivity to common airborne chemicals. A total of 3460 individuals participating in a general health examination, Health 2006, were patch tested with allergens from the European standard series and screened for chemical sensitivity with a standardised questionnaire dividing the participants into four severity groups of chemical sensitivity. Both allergic and non-allergic cutaneous reactions--defined as irritative, follicular, or doubtful allergic reactions--were analysed in relationship with severity of chemical sensitivity. Associations were controlled for the possible confounding effects of sex, age, asthma, eczema, atopic dermatitis, psychological and social factors, and smoking habits. In unadjusted analyses we found associations between allergic and non-allergic cutaneous reactions on patch testing and the two most severe groups of self-reported sensitivity to airborne chemicals. When adjusting for confounding, associations were weakened, and only non-allergic cutaneous reactions were significantly associated with individuals most severely affected by inhalation of airborne chemicals (odds ratio = 2.5, p = 0.006). Our results suggest that individuals with self-reported chemical sensitivity show increased non-allergic cutaneous reactions based on day 2 readings of patch tests. Copyright © 2011 Elsevier GmbH.

Cutaneous manifestations of myeloid malignancies are common and have a broad range of presentations. These skin findings are classified as specific, due to direct infiltration by malignant hematopoietic cells, or non-specific. Early recognition and diagnosis can have significant clinical implications, as skin manifestations may be the first indication of underlying hematologic malignancy, can reflect the immune status and stage of disease, and cutaneous reactions may occur from conventional and targeted agents used to treat myeloid disease. In addition, infections with cutaneous involvement are common in immunocompromised patients with myeloid disease. Given the varying presentations, dermatologic findings associated with myeloid malignancies can pose diagnostic challenges for hematologists and dermatologists. In this clinical review intended for the practicing hematologist/oncologist, we discuss the presentation, diagnosis, treatment, and prognostic value of the most common cutaneous manifestations associated with myeloid malignancies using illustrative macro- and microscopic figures and with a special emphasis on practical considerations.

Full Text Available Summary: Glucantime remains the first-line treatment for cutaneous leishmaniasis. In a prospective study, we evaluated its efficacy and side effects in patients treated in Yazd from 2010 to 2011. Methods: Patients with lesions compatible with cutaneous leishmaniasis were considered eligible for inclusion in this study if the disease was confirmed parasitologically. The exclusion criteria were as follows: the patient preferred a treatment modality other than Glucantime; there was no indication for treatment; the patient had underlying kidney, liver, or cardiac disease; or was pregnant and lactating.Patients with ≤3 lesions and/or lesions <3 cm in diameter were treated with Glucantime intralesionally if the lesions were not located on the face, neck or joints; sporotrichoid; or superinfected with bacteria. All other patients were prescribed intramuscular Glucantime at 10–20 mg/kg/day for 20 days. Results: The failure rate for patients treated with one course of Glucantime was 22.6% overall. There were no associations between age, sex, weight, the route of administration, the number and size of lesions, the adequacy of the dose of the drug injected intramuscularly, the number of intralesional injections (<6 or ≥6 and the duration of therapy. The only factor associated with failure was reported previous exposure to antimony (p value 0.047. Adverse effects occurred in 14.2% of patients (22/155. Conclusion: Glucantime is an effective drug for the treatment of cutaneous leishmaniasis in central Iran. However, because cutaneous leishmaniasis heals spontaneously and to prevent the acquisition of resistance, the indications for treatment in each region should be defined carefully. Keywords: Cutaneous leishmaniasis, Efficacy, Glucantime, Iran

Tumor cells show alterations in their glycosylation patterns when compared to normal cells. Lectins can be used to evaluate these glycocode changes. Chemiluminescence assay is an effective technique for quantitative analysis of proteins, nucleic acids, and carbohydrates due to its high sensitivity, specificity, and rapid testing. To use histochemiluminescence based on lectin conjugated to acridinium ester (AE) for the investigation of glycophenotype changes in cutaneous tumors. Concanavalin A (Con A), Peanut agglutinin (PNA), Ulex europaeus agglutinin-I (UEA-I), and Maackia amurensis agglutinin (MAA) were conjugated to acridinium ester. Biopsies of cutaneous tumors and normal skin were incubated with the lectins-AE, and chemiluminescence was quantified and expressed as Relative Light Units (RLU). Results. Actinic keratosis (AK), keratoacanthoma (KA), squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) showed lower expression of α -D-glucose/mannose and α -L-fucose residues compared to normal tissue. Cutaneous tumors displayed higher expression of Gal- β (1-3)-GalNAc residues than normal tissue. AK and SCC exhibited higher expression of Neu5Ac- α (2,3)Gal residues than normal epidermis. KA and BCC showed equivalent RLU values compared to normal tissue. Lectin histochemiluminescence allowed quantitative assessment of the carbohydrate expression in cutaneous tissues, contributing to eliminate the subjectivity of conventional techniques used in the histopathological diagnosis.

Cutaneous metastasis is the result of malignant cell spread from primary malignancy to the skin. This is not uncommon, and rates reported in the literature are as high as 10.4%. To the best of our knowledge, there are no studies assessing the epidemiologic, clinical, and histopathological features of cutaneous metastasis in our region. To assess the clinical and histopathological findings of all patients diagnosed with cutaneous metastasis at the American University of Beirut - Medical Center (AUB-MC) and to compare our findings with those published in the literature. Retrospective clinical and histopathologic evaluation of all cases diagnosed as cutaneous metastasis at AUB-MC between 1992 and 2010. A total of 72 patients (50 females and 22 males) were identified. The mean age at diagnosis was 55.2 years. The most common primary cancer was breast cancer in women and laryngeal cancer in men. The most common clinical presentation was a single nodule in 27% of cases followed by multiple nodules in 23%. Cutaneous metastasis lesions were asymptomatic in the majority. The chest was the most commonly affected site. On microscopy, the majority of metastatic cases were adenocarcinomas (74%). This is, to our knowledge, the first study characterizing the epidemiological, clinical, and histopathological features of cutaneous metastasis in the Lebanese population. The clinical and histopathological features observed were in concordance with the published literature, with minor differences. © 2013 The International Society of Dermatology.

Atrial natriuretic peptide (ANP) is a powerful vasodilating peptide secreted by cardiac muscle cells, and endothelial progenitor cells (EPCs) have been reported to stimulate cutaneous wound healing by mediating angiogenesis. To determine whether ANP can promote the EPC-mediated repair of injured tissues, we examined the effects of ANP on the angiogenic properties of EPCs and on cutaneous wound healing. In vitro, ANP treatment enhanced the migration, proliferation, and endothelial tube-forming abilities of EPCs. Furthermore, small interfering RNA-mediated silencing of natriuretic peptide receptor-1, which is a receptor for ANP, abrogated ANP-induced migration, tube formation, and proliferation of EPCs. In a murine cutaneous wound model, administration of either ANP or EPCs had no significant effect on cutaneous wound healing or angiogenesis in vivo, whereas the co-administration of ANP and EPCs synergistically potentiated wound healing and angiogenesis. In addition, ANP promoted the survival and incorporation of transplanted EPCs into newly formed blood vessels in wounds. These results suggest ANP accelerates EPC-mediated cutaneous wound healing by promoting the angiogenic properties and survival of transplanted EPCs. This article is protected by copyright.

Two 8-hydroxyquinoline derivatives, 5,7-dichloro-8-hydroxyquinoline (57DC8HQ) and 5-chloro-7-iodo-8-hydroxy quinoline (5CL7I8HQ) have been investigated in details by means of spectroscopic characterization and computational molecular modelling techniques. FT-IR and FT-Raman experimental spectroscopic approaches have been utilized in order to obtain detailed spectroscopic signatures of title compounds, while DFT calculations have been used in order to visualize and assign vibrations. The computed values of dipole moment, polarizability and hyperpolarizability indicate that the title molecules exhibit NLO properties. The evaluated HOMO and LUMO energies demonstrate the chemical stability of the molecules. NBO analysis is made to study the stability of the molecules arising from hyperconjugative interactions and charge delocalization. DFT calculations have been also used jointly with MD simulations in order to investigate in details global and local reactivity properties of title compounds. Also, molecular docking has been also used in order to investigate affinity of title compounds against decarboxylase inhibitor and quinoline derivatives can be a lead compounds for developing new antiparkinsonian drug.

Furthermore cutaneous paraneoplastic disorders often precede a diagnosis of cancer. We present 2 unique case reports with cutaneous paraneoplastic manifestations. The first one describes a patient with sudden progression of long-term stabilized morphea in connection with newly diagnosed hepatocellular carcinoma (HCC. The second one describes female patient with breast cancer preceded by the development of extragenital lichen sclerosus (LS with typical sclerotic lesions and hemorrhagic bullae.

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.

Chronic cheek ulcer caused by odontogenic cutaneous sinus tract

Odontogenic cutaneous sinus tracts are often misdiagnosed, and they lead to facial wounds and scarring. Therefore, we must be aware of the possibility of this condition. A dental origin must be considered for chronic ulcers involving the cheek, chin and submental areas. The clinical course of this patient suggests two important clinical issues for prompt diagnosis. First, physical examination, including palpation and probing, are helpful for exploration of sinus tracts. Second, computed tomography is useful to detect the sinus tract and affected teeth. Computed tomography provides radiographic evidence of the relationship between the tooth and cutaneous region, and it may be superior to radiography.

The appearance of skin symptoms in male breast is the main reason for consultation in our context. The aim of this study is to describe the various cutaneous manifestations of male breast cancer through a series of cases collected in a dermatology department. A retrospective study was conducted in the dermatology department at the CHU Ibn Rochd January 1988 to December 2009. All cases of male breast cancer initially diagnosed in dermatology were included. The various epidemiological, clinical, histological and therapeutic data were collected from medical records. Twenty cases were collected. The mean age was 61.25 years. Skin invasion by tumor was found in all patients, and it was the reason for consultation. It was a cutaneous involvement at the nipple and areola (17 cases) and at the periareolar skin (three cases). The clinical appearance of skin involvement was vegetative type in 12 cases, infiltrating with nipple retraction in five cases and nodule with skin change in three cases. The average period of consultation was 25 months. The axillary lymph nodes were noted in 11 patients and distant metastases in eight patients. The cutaneous metastases outside breast were noted in six patients. The histological types were: infiltrating ductal carcinoma in 15 cases (75%), papillary carcinoma in two cases (10%) and non-specific carcinoma in three cases (15%). The treatment was surgery in 14 patients and consisted of radical mastectomy with complete axillary nodal dissection according to Patey. Complementary therapies, chemotherapy or radiotherapy, were indicated in 14 patients. Our single-center study with dermatological recruitment illustrates the frequency and variety of skin disease in male breast cancer and demonstrates that they are still the main reason for consultation in our context. Better information for public and practitioners would allow earlier diagnosis and a more favourable prognosis. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Perineural spread (PNS) of cutaneous squamous cell carcinoma of the head and neck (SCCHN) can be associated with poor outcomes. Disease understanding and awareness is limited leading to delayed diagnosis and treatment. The purpose of this study was to identify epidemiological features of patients with PNS of cutaneous SCCHN. Tumor characteristics and demographics of patients with PNS of cutaneous SCCHN managed through a single institution were collected between 1998 and 2013. One hundred twenty patients were included in this study. The majority had a history of skin cancer (85.8%). The median time from primary tumor treatment to PNS symptom onset was 16 months (range, 1-86 months). A total of 34.2% had no perineural invasion (PNI) detected in the primary, and 22.5% had no known primary tumor. Only 5.8% of the patients had nodal involvement at presentation. Patients can present with PNS from cutaneous SCCHN with no known primary tumor or with primary tumors without PNI. The majority of patients presented without regional nodal involvement. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1416-1420, 2016. © 2016 Wiley Periodicals, Inc.

Quattrone, Filippo; Dini, Valentina; Barbanera, Sabrina; Zerbinati, Nicola; Romanelli, Marco

2013-11-01

Hydroxyurea is an antitumoral drug mainly used in the treatment of Philadelphia chromosome-negative myeloproliferative syndromes and sickle-cell disease. Ulcers represent a rare but severe long-term adverse effect of hydroxyurea therapy. Hydroxyurea-induced ulcers are often multiple and bilateral, typically developing in the perimalleolar region, although any cutaneous district is potentially affected. They generally look small, well-defined, shallow with an adherent, yellow, fibrinous necrotic base. A constant finding is also an extremely intense, treatment-resistant pain accompanying these ulcerations. Withdrawal of the drug generally leads to spontaneous healing of these lesions. Care providers tend to show insufficient awareness of this highly debilitating cutaneous side effect, and late or missed diagnoses are frequent. Instead, regular dermatologic screening should be performed on hydroxyurea-treated patients. This article will present a comprehensive review of indexed case reports and clinical studies, followed by a discussion about treatment options aiming at increasing knowledge about this specific topic.

Thirty-two confirmed cases of non -Hodgkin's lymphoma (NHL) were examined for cutaneous manifestations for a period of 2 years from November 1998 in KMC Hospital Attavar, Mangalore. Cutaneous manifestations in the study group were compared to a control group of 32 patients. Specific infiltrates were present in all (5/5) CTCL patients and one out of twenty-seven patients with low grade NHL. Morphologically they presented as papules, plaques, nodules and erythroderma. Infective conditions seen in the study group were superficial fungal (7/32) and viral infections (2/ 32). Non-infective conditions were acquired ichthyosis (10/32), generalised pruritus (5/32), insect bite reaction (1/32) and drug eruption (1/32). When compared to control patients only acquired ichthyosis and generalised pruritus were found to be statistically significant. The study group also showed changes due to chemotherapy like diffuse alopecia (24/29), bluish pigmentation of proximal part of nail (4/29), localised pigmentation of palms and soles (1 /29), diffuse pigmentation at injection site (1 /29), pigmentation at scar site (1 /29) and stomatitis (4/29).

A 5-year-old male miniature dachshund was presented with a dermal nodule on the left forelimb that increased to 5 mm in diameter over a 2-month period. Grossly, the nodule was firm, and both the external and cut surfaces were homogeneously pale pink in colour. Microscopically, the nodule was comprised of mainly plump endothelial cells and inflammatory cells; among the latter, lymphocytes were predominant, with few scattered plasma cells, mast cells and macrophages. Lymphoid follicles with germinal centres were often observed. Mitotic figures were not observed amongst the endothelial cells. Immunohistochemically, the endothelial cells were positive for vimentin, factor VIII-related antigen and CD31, and the surrounding cells were positive for smooth muscle actin. Lymphocytes expressed CD3 or BLA36. These findings led to a diagnosis of cutaneous angiolymphoid hyperplasia. To the best of our knowledge, this is the first report of a cutaneous proliferative disorder comprising an admixture of proliferating vascular endothelial cells and lymphocytic infiltration with follicle formation in a dog.

Zahoor, Bilal; Kent, Stephen; Wall, Daryl

2016-07-01

Mucormycosis is a rare but serious sequelae of penetrating trauma [1-5]. In spite of aggressive management, mortality remains high due to dissemination of infection. We completed a review of literature to determine the most optimal treatment of cutaneous mucormycosis which occurs secondary to penetrating trauma. We completed a review regarding the management of mucormycosis in trauma patients. We selected a total of 36 reports, of which 18 were case-based, for review. Surgical debridement is a primary predictor of improved outcomes in the treatment of mucormycosis [3,6,7]. Anti-fungal therapy, especially lipid soluble formulation of Amphotericin B, is helpful as an adjunct or when surgical debridement has been maximally achieved. Further research is needed to fully evaluate the impact of topical dressings; negative pressure wound therapy is helpful. An aggressive and early surgical approach, even at the expense of disfigurement, is necessary to reduce mortality in the setting of cutaneous mucormycosis that results from penetrating trauma [4,8,9]. Anti-fungal therapy and negative pressure wound therapy are formidable adjuncts. Copyright © 2016 Elsevier Ltd. All rights reserved.

Primary cutaneous anaplastic large cell lymphoma masquerading as large pyogenic granuloma

2016-01-01

Full Text Available Primary cutaneous anaplastic large cell lymphoma (pcALCL forms 9% of the cutaneous T-cell lymphomas. It usually presents as solitary reddish brown ulcerating nodule or indurated plaque. Sometimes, it mimics other dermatological diseases such as eczema, pyoderma gangrenosum, pyogenic granuloma, morphea, and squamous cell carcinoma. Our case presented with large pyogenic granuloma like lesion with regional lymphadenopathy. Since pcALCL is rare, one can misdiagnose such cases and therefore high index of suspicion is necessary.

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)

Human papilloma virus (HPV) infects keratinocytes of the skin and mucous membranes, and is associated with the induction of cutaneous warts and malignancy. Warts can induce significant morbidity and disability but most therapies, including cryotherapy, laser, and radiofrequency devices show low efficacy and induce discomfort through tissue destruction. Microwaves are readily capable of passing through highly keratinised skin to deliver energy and induce heating of the tissue in a highly controllable, uniform manner. To determine the effects of microwave on cutaneous HPV infection. We undertook a pilot study of microwave therapy to the skin in 32 consecutive individuals with 52 recalcitrant long-lived viral cutaneous warts. Additionally, we undertook a molecular characterisation of the effects of microwaves on the skin. Tissue inflammation was minimal, but 75.9% of lesions cleared which compares favourably with previous studies showing a clearance rate of 23-33% for cryotherapy or salicylic acid. We show that microwaves specifically induce dendritic cell cross-presentation of HPV antigen to CD8+ T cells and suggest that IL-6 may be important for DC IRF1 and IRF4 modulation to enhance this process. Keratinocyte-skin dendritic cell cross-talk is integral to host defence against HPV infections, and this pilot study supports the concept of microwave induction of anti-HPV immunity which offers a promising approach for treatment of HPV-induced viral warts and potentially HPV-related cancers.

Primary cutaneous mucormycosis is a rare but often lethal severe fungal infection, which usually occurs in immunocompromised patients. We report a case of primary cutaneous mucormycosis caused by Mucor irregularis in an elderly patient. Seven months after the surgical dissection of the involved skin, cutaneous mucormycosis recurred at the peripheral edge of the skin graft. Shortly subsequent to the administration of liposomal amphotericin B, the remaining skin lesion was excised again. M. irregularis is rarely but increasingly reported as a cause of mucormycosis in immunocompetent individuals, especially in Asian farmers. M. irregularis may be largely disseminated in the soils of Asia and thus the trivial trauma at the time of farm work may be a trigger for the onset. These cases tend to leave severe cosmetic damage even in healthy individuals, although the vital prognosis is not affected. © 2014 Japanese Dermatological Association.

Full Text Available Background: The diagnosis of cutaneous adversities in the cancer patient is especially difficult, given the complexity of their illness and combination protocols used for the treatment. The present study was undertaken to know the spectrum of cutaneous adversities in patients undergoing chemotherapy and the drug(s most commonly associated with it. Materials and Methods: A total of 1000 patients with malignancies under chemotherapy in the oncology ward and outpatient department were screened in this observational study from January 2013 to February 2015. Relevant investigations for diagnosis of malignancies under chemotherapy and dermatological disorders were carried out. Results: Three hundred and eighty-four patients presented with cutaneous adversities of chemotherapy. The most common was anagen effluvium (78.6%, followed by xerosis (4.4%, thrombophlebitis (3.1%, generalised pruritus (2.9%, melanonychia (2.9%, hand-foot syndrome (2.6%, extravasation reactions (1.8%, flagellate dermatosis (1.3%, prurigo nodularis (0.8%, exfoliation (0.5%, ichthyosis (0.5%, papulopustular rash (0.3%, bullous photodermatitis (0.3%, and Sweet's syndrome (0.3%. Chemotherapeutic drugs were mostly given in combinations. Most common drugs to cause anagen effluvium were alkylating agents in combinations, hand-foot syndrome by taxanes (docetaxel, flagellate dermatoses by antitumour antibiotics (bleomycin, and exfoliation by antimetabolites (methotrexate. The limitation of this study was to imply a specific drug as the causation of the cutaneous adversities since the chemotherapy mostly consisted of combination protocols. Therefore, we have tried to associate the drug combination itself. Conclusion: Chemotherapeutic drugs produce a range of cutaneous adversities, certain specific adversities pertaining to drugs, and their combinations have been implicated which should be looked for and managed accordingly. Knowledge of the adverse effects of anticancer drugs will help

Cutaneous community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA) has been identified in otherwise healthy individuals either with or without methicillin-resistant S. aureus (MRSA)-associated risk factors who participate in athletic activities. The purpose of this study was to describe the clinical features of CAMRSA skin infection that occurred in university student athletes, evaluate the potential mechanisms for the transmission of MRSA infection of the skin in participants of athletic activities, and review the measures for preventing the spread of cutaneous CAMRSA infection in athletes. A retrospective chart review of the student athletes from the University of Houston whose skin lesions were evaluated at the Health Center and grew MRSA was performed. The clinical characteristics and the postulated mechanisms of cutaneous MRSA infection in the athletes were compared with those previously published in reports of CAMRSA skin infection outbreaks in other sports participants. Cutaneous CAMRSA infection occurred in seven student athletes (four women and three men) who were either weight lifters (three students) or members of a varsity sports team: volleyball (two women), basketball (one woman), and football (one man). The MRSA skin infection presented as solitary or multiple, tender, erythematous, fluctuant abscesses with surrounding cellulitis. The lesions were most frequently located in the axillary region (three weight lifters), on the buttocks (two women), or on the thighs (two women). The drainage from all of the skin lesions grew MRSA, which was susceptible to clindamycin, gentamicin, rifampin, trimethoprim/sulfamethoxazole, and vancomycin; five of the isolates were also susceptible to ciprofloxacin and levofloxacin. All of the bacterial strains were resistant to erythromycin, oxacillin, and penicillin. The cutaneous MRSA infections persisted or worsened in the six athletes who were empirically treated for methicillin-sensitive S. aureus at

Haptic stimulation can help humans learn perceptual motor skills, but the precise way in which it influences the learning process has not yet been clarified. This study investigates the role of the kinesthetic and cutaneous components of haptic feedback during the learning of a viscous curl field, taking also into account the influence of visual feedback. We present the results of an experiment in which 17 subjects were asked to make reaching movements while grasping a joystick and wearing a pair of cutaneous devices. Each device was able to provide cutaneous contact forces through a moving platform. The subjects received visual feedback about joystick's position. During the experiment, the system delivered a perturbation through (1) full haptic stimulation, (2) kinesthetic stimulation alone, (3) cutaneous stimulation alone, (4) altered visual feedback, or (5) altered visual feedback plus cutaneous stimulation. Conditions 1, 2, and 3 were also tested with the cancellation of the visual feedback of position error. Results indicate that kinesthetic stimuli played a primary role during motor adaptation to the viscous field, which is a fundamental premise to motor learning and rehabilitation. On the other hand, cutaneous stimulation alone appeared not to bring significant direct or adaptation effects, although it helped in reducing direct effects when used in addition to kinesthetic stimulation. The experimental conditions with visual cancellation of position error showed slower adaptation rates, indicating that visual feedback actively contributes to the formation of internal models. However, modest learning effects were detected when the visual information was used to render the viscous field.

PREVENTION OF CUTANEOUS SIDE EFFECTS OF TOPICAL TRETINOIN: USE OF ORAL VITAMINE E

Directory of Open Access Journals (Sweden)

G FAGHIHI

2001-03-01

Full Text Available Introduction: Acne vulgaris is an inflammatory disease of pilosebaceous folicles. Tretinoin is used as one of the topical treatments for acne vulgaris. It has different cutaneous side effects such as erythema, scaling, irritation and photosensitivity. The aim of this study was to evaluate the efficacy of oral Vitamine E in preventing the cutaneous side effects of topical tretinoin in acne patients.
Methods: A clinical trial was performed in AI-Zahra Hospital in Isfahan for six months in 2000. 80 patients with mild to moderate facial acne were randomized into 2 groups. Group 1 (controls received topical solution of tretinoin 0.05 percent nightly and group 2 (cases received daily oral 100mg of Vit. E in addition. All patients were followed at 1, 4 and 6 weeks after initiation of treatment. Children under 12 years old, pregnant or lactating women were excluded.
Results: At the end of one week, no cutaneous side effects were observed in 25 percent (10 of group 1 and 15 percent (6 of group 2 (P > 0.05. At the end of 4 weeks, 25 percent (10 of group 1 and 60 percent (24 of group 2 were without any cutaneous complications, while at the end of 6 weeks, 35 percent (14 of group 1 in comparison to 75 percent (30 of group 2 were free of any cutaneous side effects (P < 0.05. The most common side effect in both groups was exfoliation.
Discussion: Daily oral 100 mg of Vit. E has been effective in preventing cutaneous complications of topical tretinoin in acne management, but there is a delay of one week in its onset of action. Meanwhile, Vitamine E is a safe modality with no undesirable effects in acne patients.

The consequences of the spread of Leishmania parasites to the blood from lesions in patients with cutaneous leishmaniasis are numerous. To assess the magnitude of this invasion we conducted the present study on patients referred to the American University of Beirut Medical Center for cutaneous leishmaniasis. Patients referred for the management of cutaneous leishmaniasis were included in the study. Skin and blood cultures for Leishmania were taken from these patients. One hundred sixty-two patients were proven to have cutaneous leishmaniasis by pathology; 52% were males and 44% females (gender information was missing for 4%). Patient age ranged from 5 months to 70 years. None of the patients had received treatment for Leishmania. We obtained parasite isolates from 85 patients (52.5%), proven by cultures from skin and blood/blood components. Interestingly, the parasite was isolated in the blood and blood components of 50 patients (30.9%). Isoenzyme analysis confirmed the fact that the organisms in blood and skin were the same; from the 28 isolates that were positive in both skin and blood, eight isolates were Leishmania major and two were Leishmania tropica. The remaining isolates, whether positive in both blood and skin or in either of these tissues, skin or blood and its products, were Leishmania infantum sensu lato. In the current study, the detection rate of parasites in the blood of patients with cutaneous leishmaniasis was high. This illustrates the invasive characteristic of the parasite that has escaped the skin. Testing should be considered in areas other than Lebanon, especially around the Mediterranean basin. Whether these findings support the administration of systemic treatment for cutaneous leishmaniasis or not needs to be confirmed in larger prospective studies. Crown Copyright © 2011.

Full Text Available The purpose of this study was to evaluate and characterize the clinical and histopathological aspects of cutaneous pythiosis in donkeys (Equus asinus in the Department of Cordoba, Colombia. A descriptive, non-probability study was conducted on domesticated animals. Nine donkeys clinically and histopathologically diagnosed with cutaneous pythiosis were analyzed. After describing the cases, a serious, crater-shaped granulomatous ulcer was observed, with necrotic tissue, a tumor appearance, abundant fibrinous-bloody exudation and yellowish-white caseous material known as kunkers. The lesions were found in the members, ventral abdomen and chest of the animals. Histopathologically, with the hematoxylin-eosin staining, severe pyogranulomatous dermatitis was observed, with abundant eosinophilic and neutrophilic inflammatory infiltrate; with the Grocott staining, hyphae with septa were found, partially branching into a right angle and brown in color.

Cutaneous wounds heal with two possible outcomes: scarification or near-perfect integumentary restoration. Whereas scar formation has been intensively investigated, less is known about the tissue-level events characterising wounds that spontaneously heal scar-free, particularly in non-foetal amniotes. Here, a spatiotemporal investigation of scar-free cutaneous wound healing following full-thickness excisional biopsies to the tail and body of leopard geckos (Eublepharis macularius) is provided. All injuries healed without scarring. Cutaneous repair involves the development of a cell-rich aggregate within the wound bed, similar to scarring wounds. Unlike scar formation, scar-free healing involves a more rapid closure of the wound epithelium, and a delay in blood vessel development and collagen deposition within the wound bed. It was found that, while granulation tissue of scarring wounds is hypervascular, scar-free wound healing conspicuously does not involve a period of exuberant blood vessel formation. In addition, during scar-free wound healing the newly formed blood vessels are typically perivascular cell-supported. Immunohistochemistry revealed widespread expression of both the pro-angiogenic factor vascular endothelial growth factor A and the anti-angiogenic factor thrombospondin-1 within the healing wound. It was found that scar-free wound healing is an intrinsic property of leopard gecko integument, and involves a modulation of the cutaneous scar repair program. This proportional revascularisation is an important factor in scar-free wound healing. © 2015 Anatomical Society.

Cutaneous lesions sensory impairment recovery and nerve regeneration in leprosy patients

Full Text Available It is important to understand the mechanisms that enable peripheral neurons to regenerate after nerve injury in order to identify methods of improving this regeneration. Therefore, we studied nerve regeneration and sensory impairment recovery in the cutaneous lesions of leprosy patients (LPs before and after treatment with multidrug therapy (MDT. The skin lesion sensory test results were compared to the histopathological and immunohistochemical protein gene product (PGP 9.5 and the p75 nerve growth factor receptors (NGFr findings. The cutaneous neural occupation ratio (CNOR was evaluated for both neural markers. Thermal and pain sensations were the most frequently affected functions at the first visit and the most frequently recovered functions after MDT. The presence of a high cutaneous nerve damage index did not prevent the recovery of any type of sensory function. The CNOR was calculated for each biopsy, according to the presence of PGP and NGFr-immunostained fibres and it was not significantly different before or after the MDT. We observed a variable influence of MDT in the recovery from sensory impairment in the cutaneous lesions of LPs. Nociception and cold thermosensation were the most recovered sensations. The recovery of sensation in the skin lesions appeared to be associated with subsiding inflammation rather than with the regenerative activity of nerve fibres.

Primary cilium depletion typifies cutaneous melanoma in situ and malignant melanoma.

Full Text Available Cutaneous melanoma is a lethal malignancy that arises spontaneously or via in situ precursor neoplasms. While melanoma in situ and locally invasive malignant melanoma can be cured surgically, these lesions can sometimes be difficult to distinguish from melanocytic nevi. Thus, the identification of histolopathologic or molecular features that distinguish these biologically distinct lesions would represent an important advance. To this end, we determined the abundance of melanocytic primary cilia in a series of 62 cases composed of typical cutaneous melanocytic nevi, melanoma in situ, invasive melanoma, and metastatic melanoma. Primary cilia are sensory organelles that modulate developmental and adaptive signaling and notably, are substantially depleted from the neoplastic epithelium of pancreatic carcinoma at a stage equivalent to melanoma in situ. In this series, we find that while nearly all melanocytes in 22 melanocytic nevi possessed a primary cilium, a near-complete loss of this organelle was observed in 16 cases of melanoma in situ, in 16 unequivocal primary invasive melanomas, and in 8 metastatic tumors, each associated with a cutaneous primary lesion. These findings suggest that the primary cilium may be used to segregate cutaneous invasive melanoma and melanoma in situ from melanocytic nevi. Moreover, they place the loss of an organelle known to regulate oncogenic signaling at an early stage of melanoma development.

Full Text Available Background. Tumor cells show alterations in their glycosylation patterns when compared to normal cells. Lectins can be used to evaluate these glycocode changes. Chemiluminescence assay is an effective technique for quantitative analysis of proteins, nucleic acids, and carbohydrates due to its high sensitivity, specificity, and rapid testing. Objective. To use histochemiluminescence based on lectin conjugated to acridinium ester (AE for the investigation of glycophenotype changes in cutaneous tumors. Methods. Concanavalin A (Con A, Peanut agglutinin (PNA, Ulex europaeus agglutinin-I (UEA-I, and Maackia amurensis agglutinin (MAA were conjugated to acridinium ester. Biopsies of cutaneous tumors and normal skin were incubated with the lectins-AE, and chemiluminescence was quantified and expressed as Relative Light Units (RLU. Results. Actinic keratosis (AK, keratoacanthoma (KA, squamous cell carcinoma (SCC, and basal cell carcinoma (BCC showed lower expression of α-D-glucose/mannose and α-L-fucose residues compared to normal tissue. Cutaneous tumors displayed higher expression of Gal-β(1-3-GalNAc residues than normal tissue. AK and SCC exhibited higher expression of Neu5Ac-α(2,3Gal residues than normal epidermis. KA and BCC showed equivalent RLU values compared to normal tissue. Conclusions. Lectin histochemiluminescence allowed quantitative assessment of the carbohydrate expression in cutaneous tissues, contributing to eliminate the subjectivity of conventional techniques used in the histopathological diagnosis.

Organ transplant recipients under immunosuppressive therapy have a highly increased risk of acquiring unusual opportunistic infections. Diagnosis of the etiology of infection may be difficult in clinical manifestations, which need further histological and biological investigations. We recently treated a male renal transplant recipient with a cutaneous phaeohyphomycosis due to Alternaria species. The diagnosis was based on microscopy and culture of the skin lesions. Treatment with oral itraconazole for 5 weeks was ineffective, then clinical improvement was achieved by combination of amphotericin B wet-packing and systemic antifungal therapy with oral voriconazole. Alternaria species are ubiquitous plant-inhabiting saprobes, which are increasingly associated with opportunistic phaeohyphomycosis in immunocompromised individuals. To the best of our knowledge, this is the second case report noting sporotrichoid pattern as the manifestation of cutaneous alternariosis. In this context, we reviewed recent renal-transplant-related cutaneous alternariosis reported in the English-language literature during 1995 to 2011 to summarize its clinical features and outcomes, and to guide clinicians in the care of kidney transplant patients with cutaneous alternariosis.

2017-01-01

Full Text Available Primary cutaneous large B-cell lymphoma (Bcl is defined as a lymphoma composed of large cells constituting more than 80% of the infiltrate and absence of extracutaneous involvement after staging investigations. In the new World Health Organization/European Organization for Research and Treatment of Cancer classification, cutaneous Bcls with large cells are of three types - primary cutaneous large Bcl leg type (PCLBCLLT, primary cutaneous follicle center lymphoma diffuse type (PCFCLDT, and primary cutaneous large Bcls other (PCLBCLO. These three different types are distinct in terms of their clinicopathological features and survival. The PCLBCLO has intermediate features between those of PCLBCLLT and PCFCLDT. We present a case of PCLBCLO in a 57-year-old male who presented with a scalp swelling. Ultrasonography examination was suggestive of a sebaceous cyst. Computed tomography scan revealed the presence of an ill-defined hyperdense region in the soft tissue of the scalp region extending into the deeper layers of the scalp. Fine-needle aspiration cytology (FNAC revealed the presence of atypical lymphoid cells. Diagnosis was confirmed by biopsy and immunohistochemistry. Patient received rituximab combined with doxorubicin, vincristine, cyclophosphamide, and prednisolone regimen with complete resolution of the lesion. We present this case for its rarity, the utility of FNAC in early diagnosis, and to discuss the differential diagnosis.

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.

Extracorporeal shock wave treatment (ESWT) has proven its clinical benefits in different fields of medicine. Tissue regeneration and healing is improved after shock wave treatment. Even in the case of burn wounds angiogenesis and re-epithelialization is accelerated, but ESWT in extensive burn wounds is impracticable. High energy ESWT influences cutaneous microcirculation at body regions remote from application site. Eighteen Sprague Dawley rats were randomly assigned to two groups and received either high energy ESWT (Group A: total 1000 impulses, 10 J) or placebo shock wave treatment (Group B: 0 impulses, 0 J), applied to the dorsal lower leg of the hind limb. Ten minutes later microcirculatory effects were assessed at the contralateral lower leg of the hind limb (remote body region) by combined Laser-Doppler-Imaging and Photospectrometry. In Group A cutaneous capillary blood velocity was significantly increased by 152.8% vs. placebo ESWT at the remote body location (p = 0.01). Postcapillary venous filling pressure remained statistically unchanged (p > 0.05), while cutaneous tissue oxygen saturation increased by 12.7% in Group A (p = 0.220). High energy ESWT affects cutaneous hemodynamics in body regions remote from application site in a standard rat model. The results of this preliminary study indicate that ESWT might be beneficial even in disseminated and extensive burn wounds by remote shock wave effects and should therefore be subject to further scientific evaluation.

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)

Mosquito bite is usually followed by a local reaction, but severe or systemic reaction may, in rare cases, occur. Allergic reactions to Aedes communis (Ac) may be underestimated due to the lack of reliable diagnostic tools. In this multicenter study, 205 individuals reporting large local reactions to Ac were enrolled and studied for cutaneous or IgE reactivity to Ac, Blattella germanica, Penaeus monodon, and Dermatophagoides pteronyssinus. Extract and molecular IgE reactivity to bees, wasps, hornets, and yellow jacket venoms were also studied in 119 patients with a clinical history of adverse reaction to Hymenoptera. Immunoblot (IB) analysis and immunoCAP IgE inhibition experiments were carried out in selected sera. Ac sensitization was recorded in 96 (46.8%) patients on SPT. Strict relationship between Ac and D. pteronyssinus, B. germanica, P. monodon, or Apis mellifera reactivity on SPT was observed. Ac IgE recognition was seen in 60/131 (45.8%) patients, 49 (81.6%) of them SPT positive, and 5/14 IB reactors. Ac IgE sensitization was associated with Tabanus spp, A. mellifera, Vespula vulgaris, and Polistes dominula reactivity. A strict relationship between Ac IgE reactivity and Api m 1, Api m 2, Api m 3, Api m 5, and Api m 10 was recorded. IgE reactivity to AC was inhibited in 9/15 cases after serum absorption with the A. mellifera extract. Both SPT and IgE Ac reactivity is observed in about half of patients with a history of large local reactions to mosquito bites. The significant relationship between Ac sensitization and either extract or single bee venom components is suggestive of a "bee-mosquito syndrome" occurrence. © 2018 S. Karger AG, Basel.

Sporotrichosis is a subcutaneous fungal infection caused by a thermally dimorphic aerobic fungus, Sporothrix schenckii. It results from traumatic inoculation or contact with animals. Most cases were reported mainly in the tropics and subtropics.   The objective of our study is to assess the clinical characteristic of cutaneous sporotrichosis among our patients. We performed a retrospective review of all cases diagnosed with cutaneous sporotrichosis from July 2004 to June 2010. Patients' medical records were retrieved and analyzed according to demography, preceding trauma, sites of lesions, clinical subtypes, treatment, and clinical response. Nineteen cases were diagnosed with cutaneous sporotrichosis with a male/female ratio of 9:10. Thirteen cases (68.4%) were able to recall preceding trauma, and seven of them reported cat scratches or cat bites. Lymphocutaneous sporotrichosis was observed in 13 cases (68.4%) followed by four cases of fixed cutaneous sporotrichosis and two cases of disseminated sporotrichosis. Histologically, 11 cases (57.8%) demonstrated a granulomatous reaction. Sporothrix schenckii was cultured in 12 cases (63.2%). Thirteen cases (68.4%) were successfully treated with oral itraconazole alone for a mean duration of 15.6 weeks. Two cases with disseminated cutaneous sporotrichosis were treated with intravenous amphotericin B.   Lymphocutaneous sporotrichosis was the most common subtype of cutaneous sporotrichosis in our series, with cat scratches or bites being the most common preceding trauma. Oral itraconazole was highly effective for the localized subtypes, whereas intravenous amphotericin B was required in disseminated cutaneous sporotrichosis. © 2012 The International Society of Dermatology.

An adult female common snapping turtle (Chelydra serpentina) had a mass on the plantar surface of the right forelimb that was removed surgically. Microscopical examination revealed many spindle cells with mild anisocytosis and anisokaryosis and a surrounding collagenous stroma. There were no mitoses. Immunohistochemistry showed that the spindle cells expressed vimentin, but not desmin. A diagnosis of cutaneous fibroma was made. Tumours are reported uncommonly in chelonian species. Cutaneous fibroma has been diagnosed in an alligator snapping turtle (Macrochelys temminckii), but not previously in a common snapping turtle. Crown Copyright © 2012. Published by Elsevier Ltd.

To review adverse cutaneous drug reactions induced by tumor necrosis factor alpha (TNF-alpha) antagonist therapy. A literature search was performed using PubMed (1996-March 2009), EMBASE, and selected MEDLINE Ovid bibliography searches. All language clinical trial data, case reports, letters, and review articles identified from the data sources were used. Since the introduction of TNF-alpha antagonist, the incidence of adverse cutaneous drug reactions has increased significantly. A wide range of different skin lesions might occur during TNF-alpha antagonist treatment. New onset or exacerbation of psoriasis has been reported in patients treated with TNF-alpha antagonists for a variety of rheumatologic conditions. TNF-alpha antagonist therapy has been associated with a lupus-like syndrome; most of these case reports occurred in patients receiving either etanercept or infliximab. Serious skin reactions such as erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis have been reported rarely with the use of TNF-alpha antagonists. As the use of TNF-alpha antagonists continues to increase, the diagnosis and management of cutaneous side effects will become an increasingly important challenge. In patients receiving TNF-alpha antagonist treatment, skin disease should be considered, and clinicians need to be aware of the adverse reactions of these drugs.

Cutaneous Papillomaviruses and Non-melanoma Skin Cancer: Causal Agents or Innocent Bystanders?

Science.gov (United States)

Hasche, Daniel; Vinzón, Sabrina E; Rösl, Frank

2018-01-01

There is still controversy in the scientific field about whether certain types of cutaneous human papillomaviruses (HPVs) are causally involved in the development of non-melanoma skin cancer (NMSC). Deciphering the etiological role of cutaneous HPVs requires - besides tissue culture systems - appropriate preclinical models to match the obtained results with clinical data from affected patients. Clear scientific evidence about the etiology and underlying mechanisms involved in NMSC development is fundamental to provide reasonable arguments for public health institutions to classify at least certain cutaneous HPVs as group 1 carcinogens. This in turn would have implications on fundraising institutions and health care decision makers to force - similarly as for anogenital cancer - the implementation of a broad vaccination program against "high-risk" cutaneous HPVs to prevent NMSC as the most frequent cancer worldwide. Precise knowledge of the multi-step progression from normal cells to cancer is a prerequisite to understand the functional and clinical impact of cofactors that affect the individual outcome and the personalized treatment of a disease. This overview summarizes not only recent arguments that favor the acceptance of a viral etiology in NMSC development but also reflects aspects of causality in medicine, the use of empirically meaningful model systems and strategies for prevention.

Inflammatory bowel diseases are associated with a broad range of cutaneous lesions. Herein we report the first case of aseptic skin abscesses associated with ulcerative colitis. Since March 2008, a 40-year-old woman presented with bilateral mammary abscesses, relapsing despite repeated antibiotic treatment. She was followed for ulcerative colitis diagnosed in 2011 by means of a rectal biopsy. Despite four surgical procedures, there was no improvement in her mammary abscesses and bilateral mastectomy was then proposed because of the persistent symptoms. Her general state of health remained stable. Clinically, there were bilateral inflammatory nodes with fistulae and pus. These lesions were extremely painful. Mild inflammatory syndrome was noted, but the immunological tests revealed nothing of note. Bacteriological, parasitological and mycological tests on biopsy specimens were negative. Histological examination of a surgical biopsy revealed lymphoplasmacytic infiltration of the dermis and subcutis with altered polymorphonuclear cells and epithelioid granuloma. The CT-scan showed no other remote lesions. The final diagnosis was cutaneous aseptic abscess syndrome associated with ulcerative colitis. Colchicine 1mg/day was initiated and resulted in regression of the skin lesions, with complete remission at one year of follow-up. Aseptic abscess syndrome must be considered in the event of recurrent aseptic cutaneous abscesses which may be associated with inflammatory bowel disease. Surgery should be avoided and treatment should be based on suitable drug therapy. Copyright © 2016. Published by Elsevier Masson SAS.

Cutaneous Radiation Syndrome : Review of Assessment and Management

International Nuclear Information System (INIS)

El-Shanshoury, H.

2016-01-01

The cutaneous radiation syndrome (CRS) refers to a number of pathologies that may become a manifest after exposure of the skin to ionizing radiation. Signs and symptoms of the CRS appear within hours of exposure; however, the development of lesions can take days to years. The latent period for the manifestation of a specific pathology depends on the characteristics of the target cells responsible for the development of that lesion and the dose of radiation delivered to those target cells. The intensity and duration of the lesions are also dose dependent. Since the depth dose distribution of a radiation source depends on the radiation quality, the development of a specific lesion, its intensity and its duration is also expected to vary with radiation quality. The Cars may appear as an isolated lesion or as a number of lesions occurring simultaneously or over different time scales. In dealing with the cutaneous tissues, the concept of dose is meaningless unless it is associated with a reference depth dose distribution to indicate the level of injury to specific target cells. Large radiation doses to the skin can cause permanent hair loss, damaged sebaceous and sweat glands, atrophy, fibrosis decreased or increased skin pigmentation, and ulceration or necrosis of the exposed tissue. However, similar lesions may develop later after much lower doses. Death from the cutaneous syndrome could result in days or longer, depending on other conditions, such as dose rate, medical care and size of injury

Unusual presentation of cutaneous leiomyoma

Full Text Available Herein, we report a case of leiomyoma cutis because of its rarity and unusual presentation. The case presented with a solitary leiomyoma lesion which was painless. However, the adjacent normal appearing area was tender. A biopsy of the lesion as well as of a portion of the adjacent normal appearing area was taken, which confirmed the diagnosis of cutaneous leiomyoma. This may suggest the dormant nature of the disease which has not yet become apparent.

Disseminated cutaneous sporotrichosis presenting as a necrotic facial mass: Case and review

[Primary cutaneous Nocardia brasiliensis cellulitis in immunocompetent child].

Science.gov (United States)

Shachor-Meyouhas, Yael; Ravid, Sarit; Suhair, Hanna; Kassis, Imad

2012-08-01

Primary cutaneous nocardiosis is an infrequent infection among children, generally affecting immunocompromised hosts. It is caused by Gram positive bacteria, partially alcohol and acid resistant which are saprophytes of the soil, water and organic matter. In most cases the causal agent enters through inhalation, and hematogenous dissemination may occur mainly among the immune compromised patients. Direct cutaneous inoculation is less frequent, especially among children. We report an 8-year old female who lives in an urban house with a small garden, who presented with an ulcer on her right shin accompanied by surrounding cellulitis, pain, swelling and fever. The patient's medical history was unremarkable, with no exposure to animals or travelling, except for rafting on the Jordan River the previous week. Culture from the ulcer grew Nocardia brasiliensis, and she recovered after 8 weeks of therapy with trimethoprim-sulphamethoxazole.

Hosoi, J; Tsuchiya, T

Olfactory stimuli modulate emotional conditions and the whole body immune system. Effects of odorant inhalation on cutaneous immune reaction were examined. Contact hypersensitivity to 2,4, 6-trinitrochlorobenzene was elicited in C57BL/6 mice. The reaction was suppressed at both the induction and elicitation phases by exposure to an odorant, citralva. Topical application of citralva or lyral/lilial did not affect the reaction. The suppressive effect of citralva was more potent than that of another odorant, lyral/lilial. Citralva decreased the number of epidermal Langerhans cells, whereas lyral/lilial had a weak effect. Citralva but not lyral/lilial induced plasma corticosterone. Glucocorticoid receptor antagonist abrogated the suppressive effect of citralva on contact hypersensitivity. Serum interleukin-12 was downregulated by exposure to citralva or lyral/lilial. These data demonstrate that olfactory stimuli regulate the cutaneous immune system.

When the foot contacts an obstacle during locomotion, cutaneous inputs activate spinal circuits to ensure dynamic balance and forward progression. In quadrupeds, this requires coordinated reflex responses between the four limbs. Here, we investigated the patterns and phasic modulation of cutaneous reflexes in forelimb and hindlimb muscles evoked by inputs from all four limbs. Five female cats were implanted to record muscle activity and to stimulate the superficial peroneal and superficial radial nerves during locomotion. Stimulating these nerves evoked short-, mid-, and longer-latency excitatory and/or inhibitory responses in all four limbs that were phase-dependent. The largest responses were generally observed during the peak activity of the muscle. Cutaneous reflexes during mid-swing were consistent with flexion of the homonymous limb and accompanied by modification of the stance phases of the other three limbs, by coactivating flexors and extensors and/or by delaying push-off. Cutaneous reflexes during mid-stance were consistent with stabilizing the homonymous limb by delaying and then facilitating its push-off and modifying the support phases of the homolateral and diagonal limbs, characterized by coactivating flexors and extensors, reinforcing extensor activity and/or delaying push-off. The shortest latencies of homolateral and diagonal responses were consistent with fast-conducting disynaptic or trisynaptic pathways. Descending homolateral and diagonal pathways from the forelimbs to the hindlimbs had a higher probability of eliciting responses compared with ascending pathways from the hindlimbs to the forelimbs. Thus, in quadrupeds, intralimb and interlimb reflexes activated by cutaneous inputs ensure dynamic coordination of the four limbs, producing a whole-body response. SIGNIFICANCE STATEMENT The skin contains receptors that, when activated, send inputs to spinal circuits, signaling a perturbation. Rapid responses, or reflexes, in muscles of the

Miltefosine in cutaneous leishmaniasis

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)

LASER TREATMENT OF BENIGN CUTANEOUS VASCULAR LESIONS

2004-07-01

Full Text Available Background. Congenital and acquired vascular lesions of the skin and subcutis are a common health problem from aesthetic and also from psycho-social point of view. However, recent advances in laser technology have enabled an efficient and safe treatment. This study presents our experience with treatment of cutaneous vascular lesions using modern laser systems. Most common benign cutaneous vascular lesions are described.Patients and methods. In years 2002 and 2003, 109 patients, 4 to 80 (mean 39 years old, Fitzpatrick skin type 1–4, with 210 benign cutaneous vascular lesions were treated using the Dualis VP® laser system (Fotona, Slovenia which incorporates the KTP and Nd:YAG lasers. Vascular lesions in the upper layers of the skin with diameter up to 1 mm were treated with the KTP laser (wavelength 532 nm. For larger vessels in deeper layer we used the Nd:YAG laser (wavelength 1064 nm. Patients graded the pain during treatment on a scale of 1–10. Clinical outcomes were evaluated 1–3 months after the last treatment: according to the percentage of clearance of the lesion compared to the adjacent normal skin and for the presence of adverse effects. According to these criteria each lesion was assigned a score: poor (0–25%, fair (26–50%, good (51–75%, excellent (76–100%.Results. Immediate response after application of a laser beam with proper characteristics was whitish-grey discoloration of treated area. Treatment results after 1–3 months were excellent in 48.1%, good 40.9%, fair in 8.6% and poor in 2.4%. Patients without prior anaesthesia graded pain during treatment from 1 to 8 (mean 4.0 and patients with EMLA® anaesthesia from 1 to 6 (mean 2.6. Side effects were frequent but minimal and transient. Erythema disappeared in several days after treatment while crusting persisted for 14 days. 3 permanent hyperpigmentations, 2 permanent hypopigmentations, 2 hypertrophic scars and 1 beam sized atrophic scar were detected at last follow

The ties that bind: what's in a title?

Science.gov (United States)

Neuhaus, Susan J

2018-03-01

Many Australian and New Zealand surgeons use the title 'Mister' rather than 'Doctor', a practice dating back to traditions established over 600 years ago. The Royal Australasian College of Surgeons is currently undergoing a period of critical self-reflection, embodied by its 'Respect' campaign. Active measures to embrace diversity and encourage women into surgery are underway. This paper reviews the historical basis to the use of gendered titles and their current use amongst fellows. De-identified demographic data from the college register of active fellows was searched by self-identified title, country or state, and gender. Data were further reviewed by surgical sub-specialty and year of fellowship. The college dataset suggests that there is significant variance in the preference for gendered titles, determined predominantly by geography rather than specialty. The highest use of gendered titles (by male and female surgeons) was in Victoria/Tasmania (58% male, 22% female) and New Zealand (81% male, 17% female). By contrast, only 2% of female surgeons in other states elected a gendered title (Miss/Mrs/Ms). Surgery is the only profession that continues to use gendered titles. As the College of Surgeons moves towards greater equity and diversity, consideration should be given to phasing out the use of gendered titles, which serve to divide rather than unite our profession. © 2017 Royal Australasian College of Surgeons.

Cutaneous horn has been a matter of discussion to mankind since time immemorial and a subject of fascination for the layman. There have been instances where certain groups saw it with angst and disgust, with a person having a large cutaneous horn on an exposed area getting a dismal look. We present a case of a 64-year-old man with a giant cutaneous horn over his left gluteal region. Cutaneous horns more commonly present in the sun-exposed areas. In our case it has presented in an uncommon site. The patient had delayed and denied medical treatment due to his superstitious beliefs, after having sought advice from faith healers leading to progression of the disease. This case has been presented for its giant size (rare variety), its location being over the gluteal region (photo-protected site) and its benign histopathology suggestive of wart in spite of the giant size.

Recent research suggests that lysosomal-associated membrane protein-2 (LAMP-2) could be one of the target antigens in the pathogenesis of vasculitides. We established a transgenic rat model, env-pX rats, with various vasculitides including cutaneous vasculitis. Human primary cutaneous vasculitis includes cutaneous polyarteritis nodosa (CPN) and Henoch-Schönlein purpura (HSP). We measured serum anti-LAMP-2 antibody levels in morbid env-pX rats and injected anti-LAMP-2 antibody into premorbid env-pX rats. We further measured serum anti-LAMP-2 antibody levels in patients with CPN and HSP. Cutaneous vasculitis was observed in ∼30% of 6-month-old morbid env-pX rats. In contrast, these findings were rare in premorbid env-pX rats under 3 months old. We also examined 85 patients with CPN and 36 adult patients with HSP. Serum anti-LAMP-2 antibody levels were determined using ELISA. Premorbid env-pX rats under 3 months old were given an i.v. injection of anti-LAMP-2 antibody at day 0 and day 7. At day 14, these rats underwent histopathological and direct immunofluorescence examination. Cell surface LAMP-2 expression of rat neutrophils was examined by flow cytometry. Serum anti-LAMP-2 antibody levels were significantly higher in morbid env-pX rats than in wild-type normal rats. In addition, the levels in the cutaneous vasculitis group of morbid env-pX rats were significantly higher than the no cutaneous vasculitis group. Intravenous anti-LAMP-2 antibody injection into premorbid env-pX rats under 3 months old induced infiltration of neutrophils into cutaneous small vessels. Anti-LAMP-2 antibody-binding neutrophils were detected there. LAMP-2 expression on the cell surface of neutrophils in premorbid env-pX rats under PMA stimulation was higher compared with controls. Serum anti-LAMP-2 antibody levels in CPN and HSP were significantly higher than those of healthy controls. These data support a positive relationship between anti-LAMP-2 antibody and cutaneous vasculitis.

Sensation is commonly impaired immediately post-stroke but little is known about the long-term changes in cutaneous sensation that have the capacity to adversely impact independence and motor-function. We investigated cutaneous sensory thresholds across the hand in the chronic post-stroke period. Cutaneous sensation was assessed in 42 community-dwelling stroke patients and compared to 36 healthy subjects. Sensation was tested with calibrated monofilaments at 6 sites on the hand that covered the median, ulnar and radial innervation territories and included both glabrous (hairless) and hairy skin. The motor-function of stroke patients was assessed with the Wolf Motor Function Test and the upper-limb motor Fugl-Meyer Assessment. Impaired cutaneous sensation was defined as monofilament thresholds >3 SD above the mean of healthy subjects and good sensation was ≤ 3 SD. Cutaneous sensation was impaired for 33% of patients and was 40-84% worse on the more-affected side compared to healthy subjects depending on the site (psensation fell within the healthy range, although ∼ 1/3 of patients were classified with impaired sensation. Classification by motor-function revealed low levels of impaired sensation. The magnitude of sensory loss was only apparent when the sensory-function of stroke patients was classified as good or impaired. Sensation was most impaired on the dorsum of the hand where age-related changes in monofilament thresholds are minimal in healthy subjects. Although patients with both high and low motor-function had poor cutaneous sensation, overall patients with low motor-function had poorer cutaneous sensation than those with higher motor-function, and relationships were found between motor impairments and sensation at the fingertip and palm. These results emphasize the importance of identifying the presence and magnitude of cutaneous sensory impairments in the chronic period after stroke.

Cutaneous sporotrichosis: Unusual clinical presentations

2010-01-01

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

Background: Squamous cell carcinoma (SCC) is a common skin cancer and its treatment is still difficult. The aim of this study was to evaluate the effectiveness of nanoparticle (NP)-assisted ALA delivery for topical photodynamic therapy (PDT) of cutaneous SCC. Methods: UV-induced cutaneous SCCs were established in hairless mice. ALA loaded polylactic-co-glycolic acid (PLGA) NPs were prepared and characterized. The kinetics of ALA PLGA NPs-induced protoporphyrin IX (PpIX) fluorescence in SCCs, therapeutic efficacy of ALA NP-mediated PDT, and immune responses were examined. Results: PLGA NPs could enhance PpIX production in SCC. ALA PLGA NP mediated topical PDT was more effective than free ALA of the same concentration in treating cutaneous SCC. Conclusion: PLGA NPs provide a promising strategy for delivering ALA in topical PDT of cutaneous SCC.

Given increased international travel, immigration, and climate change, bacterial and viral infections that were once unrecognized or uncommon are being seen more frequently in the Western Hemisphere. A delay in diagnosis and treatment of these diseases can lead to significant patient morbidity and mortality. However, the diagnosis and management of these infections is fraught with a lack of consistency because there is a dearth of dermatology literature on the cutaneous manifestations of these infections. We review the epidemiology, cutaneous manifestations, diagnosis, and management of these emerging bacterial and viral diseases. Copyright © 2016 American Academy of Dermatology, Inc.

4-Chloro-2-(3-fluorophenyl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-1-one (CFPDPPO) have been synthesized by hydride transfer from Et3SiH to carbenium ions(reduction reaction), which is formed by reaction between 4-chloro-2-(3-fluorophenyl)-3-hydroxy-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-1-one with TFA, the single crystals were grown in acetonitrile by slow evaporation technique at room temperature and characterized by single crystal X-ray diffraction, FT-IR, FT-Raman, 1H NMR, 13C NMR and ESI-MS. The experimental vibrational spectra were compared with the calculated spectra and each vibrational wavenumber was assigned on the basis of potential energy distribution (PED). Gauge-including atomic orbital 1H NMR and 13C NMR chemical shifts calculations were carried out and compared with experimental data. The HOMO and LUMO analysis is used to determine the charge transfer within the molecule. The stability of the molecule arising from hyper-conjugative interactions and charge delocalization has been analysed using NBO analysis. First hyperpolarizability is calculated in order to find its role in non-linear optics. Besides molecular electrostatic potential (MEP), global reactivity descriptors, thermodynamic properties, and Mullikan charge analysis of the title compound were computed with the same method in gas phase, theoretically. Further, employing combination of DFT calculations and molecular dynamics (MD) simulations, we have investigated in detail reactive properties of the title molecule. Investigation of local reactive properties encompassed calculations of average local ionization energies (ALIE) and Fukui functions. Stability in water has been investigated by calculations of radial distribution functions (RDF), while sensitivity towards the mechanism of autoxidation has been investigated by calculations of bond dissociation energies (BDE). The docked ligand forms a stable complex with human alpha9 nicotinic acetylcholine receptor antagonist and can be a lead

Full Text Available Background: Determination of the division history of T cells in vitro is helpful in the study of effector mechanisms against infections. Technique described here uses the intracellular fluorescent label carboxyfluorescein diacetate succinimidyl ester (CFSE to monitor the proliferation. Methods: In a cross sectional study, blood samples were collected from 7 volunteers with history of cutaneous leishmania­sis (CL and one healthy control from endemic areas in Isfahan province who referred to the Center for Research and Training in Skin Diseases and Leprosy (CRTSDL, then CD4+/CD8+ lymphocytes and CD14+ monocytes were isolated from peri­pheral blood mononuclear cells (PBMC using mAbs and magnetic nanoparticles. CFSE labeled CD4+ or CD8+ lympho­cytes cultured with autologous monocytes in the presence of PHA, SLA, live Leishmania major or as control with­out sti­mulation. Cells were harvested after 7 days and were analyzed using flow cytometry. Results: Five consecutive divisions were monitored separately. Stimulation of CD4+ or CD8+ lymphocytes from CL sub­jects with SLA showed a significant difference in proliferation comparing with unstimulated cells (P< 0.05. The signifi­cant difference in the percentages of CD4+ cells stimulated with SLA was revealed at different divisions for each subject. In CD8+ lymphocyte, significant stronger stimulation of SLA was evident later in the proliferation process. The mean number of divisions in both CD4+/CD8+ lymphocytes stimulated with SLA was significantly greater than when stimulated with live L. major (P=0.007 / P=0.012, respectively Conclusion: The percentage of divided cells might be calculated separately in each division. The cells remained active following CFSE staining and there is possibility of functional analysis simultaneously.

Full Text Available Round cell neoplasms (RCNs are frequent cutaneous lesions in dogs, with high percentages among skin tumors. In this category are included histiocytoma, mast cell tumor, plasmacytoma, lymphoma and transmissible venereal tumor. The aim of the study was to perform an epidemiological study with reference to the cutaneous round cell tumors in a period of 10 years in the Department of Pathology (Faculty of Veterinary Medicine, Cluj-Napoca, Romania. Additionally, in the recorded cases with round cell tumors (mast cell tumor, histiocytoma and lymphoma we described the main histological and cytological features. The epidemiological data were collected from the records of Pathology Department between 2005-2014. The investigation included dogs diagnosed with cutaneous round cell neoplasms, following necropsy analysis or assessment of biopsies or cytological samples. All collected specimens were analyzed by histopathological and/or cytological techniques. The staining used for histological investigation were Hematoxylin-eosin, Masson’s trichrome and Toluidine blue, whereas Diff Quik and Wright methods were utilized in cytological specimens. The distribution of the cutaneous round cell tumors in relation to age, breed and sex was also assessed. The most frequent round cell tumor type was the mast cell tumor (19.54% followed by histiocytoma (11.33% and lymphoma (1.98%. The round cell tumors recorded were equally distributed in both males and females. Concerning the distribution of cutaneous RCNs by age (average age, histiocytoma occurred in 5 years old subjects, mast cell tumor in 11.9 years old subjects, and lymphoma in 6 years old subjects. Mast cell tumor was more frequent in stray dogs and Boxer breed, while histiocytoma occurred more commonly in stray dogs. Histological and cytological analysis was mandatory to perform the differential diagnosis between RCNs. Microscopic details concerning cytoplasm and nucleus of tumoral cells, together with the

Cutaneous melanoma (CM) is considered serious for causing frequent metastasis, presenting high mortality, resistance to available therapies and incidences in laboring activity. To study the histopathological types of cutaneous melanoma in Palmas-TO from 2001 to 2011, according to risk factors, location of lesions, Clark levels and Breslow thickness. A descriptive, retrospective and quantitative research in reports of the Serviços de Anatomia Patológica in Palmas (SAPP) and Registro de Câncer de Base Populacional de Palmas (RCBPP). The years of highest incidences were: 2004 (8 cases/17.8%), 2008 and 2011 (7 cases each/15.6%) and 2010 (6 cases/13.3%). Among the 45 cases studied, there were predominance in patients between 41 and 60 years old, women, caucasians, farmers, located in trunk, in situ type, superficial extensive and metastatic cutaneous, Clark levels I (20%) and IV (17.7%), Breslow thickness ≤1 mm (35.5%) and 2.01 to 4 mm (24.4%). The most common histopathological types were: cutaneous melanoma in situ, superficial extensive and metastatic, followed by nodular cutaneous melanoma, and finally, by other forms. In this study, Clark levels and Breslow thickness pointed to greater importance of thin melanomas and sun exposure without appropriate protection in farmers.

Natural history of sensory nerve recovery after cutaneous nerve injury following foot and ankle surgery

Directory of Open Access Journals (Sweden)

Lu Bai

2015-01-01

Full Text Available Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Patients received oral vitamin B 12 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory function in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months

Cutaneous toxoplasmosis is a rare and diagnostically challenging entity. Today, the acquired form occurs predominantly in immunocompromised patients with human immunodeficiency virus or after hematopoietic stem cell transplantation. We report a case of cutaneous toxoplasmosis in a 6-year-old girl after allogeneic stem cell transplantation for immune-mediated encephalopathy, first manifesting at 16 months of age. In the post-transplant setting, she developed a rash consisting of approximately 8 scattered 3–4-mm round, erythematous macules and papules on her back, abdomen, and right shoulder. Sections from a biopsy of a lesion on the back revealed numerous spherules tightly packed within small cystic structures in the epidermis. The diagnosis of cutaneous toxoplasmosis was confirmed by an immunohistochemical stain for Toxoplasma gondii and polymerase chain reaction on the peripheral blood for the T. gondii genome. This case should raise awareness that acquired toxoplasmosis with cutaneous involvement can occur in the pediatric population, particularly in immunocompromised patients after stem cell transplantation. Early diagnosis and treatment of this life-threatening opportunistic infection may improve patient outcomes.

Although the pattern of BAP1 inactivation in ocular melanoma specimens and in the BAP1 cutaneous/ocular melanoma (CM/OM) predisposition syndrome suggests a tumor suppressor function, the specific role of this gene in the pathogenesis of cutaneous melanoma is not fully understood. We thus set out to characterize BAP1 in cutaneous melanoma and discovered an unexpected pro-survival effect of this protein. Tissue and cell lines analysis showed that BAP1 expression was maintained, rather than lost, in primary melanomas compared to nevi and normal skin. Genetic depletion of BAP1 in melanoma cells reduced proliferation and colony forming capability, induced apoptosis and inhibited melanoma tumor growth in vivo. On the molecular level, suppression of BAP1 led to a concomitant drop in the protein levels of survivin a member of anti-apoptotic proteins and a known mediator of melanoma survival. Restoration of survivin in melanoma cells partially rescued the growth-retarding effects of BAP1 loss. In contrast to melanoma cells, stable overexpression of BAP1 into immortalized but non-transformed melanocytes did suppress proliferation and reduce survivin. Taken together, these studies demonstrate that BAP1 may play a growth-sustaining role in melanoma cells, but that its impact on ubiquitination underpins a complex physiology which is context and cell dependent.

In vivo photoacoustic microscopy of human cutaneous microvasculature and a nevus.

Science.gov (United States)

Favazza, Christopher P; Jassim, Omar; Cornelius, Lynn A; Wang, Lihong V

2011-01-01

In several human volunteers, photoacoustic microscopy (PAM) has been utilized for noninvasive cutaneous imaging of the skin microvasculature and a melanocytic nevus. Microvascular networks in both acral and nonacral skin were imaged, and multiple features within the skin have been identified, including the stratum corneum, epidermal-dermal junction, and subpapillary vascular plexus. Several vascular and structural differences between acral and nonacral skin were also observed in the photoacoustic images. In addition, a nevus was photoacoustically imaged, excised, and histologically analyzed. The photoacoustic images allowed for in vivo measurement of tumor thickness, depth, and microvasculature-values confirmed by histologic examination. The presented images demonstrate the potential of PAM to aid in the study and evaluation of cutaneous microcirculation and analysis of pigmented lesions. Through its ability to three-dimensionally image the structure and function of the microvasculature and pigmented lesions, PAM can have a clinical impact in diagnosis and assessment of systemic diseases that affect the microvasculature such as diabetes and cardiovascular disease, cutaneous malignancies such as melanoma, and potentially other skin disorders.

2018-03-01

In vivo imaging of the complex cascade of events known to be pivotal elements in the healing of cutaneous wounds is a difficult but essential task. Current techniques are highly invasive, or lack the level of vascular and structural detail required for accurate evaluation, monitoring and treatment. We aimed to use an advanced optical coherence tomography (OCT)-based angiography (OCTA) technique for the non-invasive, high resolution imaging of cutaneous wound healing. We used a clinical prototype OCTA to image, identify and track key vascular and structural adaptations known to occur throughout the healing process. Specific vascular parameters, such as diameter and density, were measured to aid our interpretations under a spatiotemporal framework. We identified multiple distinct, yet overlapping stages, hemostasis, inflammation, proliferation, and remodeling, and demonstrated the detailed vascularization and anatomical attributes underlying the multifactorial processes of dermatologic wound healing. OCTA provides an opportunity to both qualitatively and quantitatively assess the vascular response to acute cutaneous damage and in the future, may help to ascertain wound severity and possible healing outcomes; thus, enabling more effective treatment options.

In vivo study of ALA PLGA nanoparticles-mediated PDT for treating cutaneous squamous cell carcinoma

Science.gov (United States)

Wang, Xiaojie; Shi, Lei; Huang, Zheng; Wang, Xiuli

2014-09-01

Background: Squamous cell carcinoma (SCC) is a common skin cancer and its treatment is still a challenge. Although topical photodynamic therapy (PDT) is effective for treating in situ and superficial SCC, the effectiveness of topical ALA delivery to thick SCC can be limited by its bioavailability. Polylactic-co-glycolic acid nanopartieles (PLGA NPs) might provide a promising ALA delivery strategy. The aim of this study was to evaluate the efficacy of ALA PLGA NPs PDT for the treatment of cutaneous SCC in a mouse model. Methods: ALA loaded PLGA NPs were prepared and characterized. The therapeutic efficacy of ALA PLGA NP mediated PDT in treating UV-induced cutaneous SCC in the mice model were examined. Results: In vivo study showed that ALA PLGA NPs PDT were more effective than free ALA of the same concentration in treating mouse cutaneous SCC. Conclusion: ALA PLGA NPs provides a promising strategy for delivering ALA and treating cutaneous SCC.

Full Text Available BACKGROUND Cutaneous vasculitis is a condition caused by various aetiologies. They can be primary or secondary. Cutaneous lesions maybe a pointer to systemic diseases. So, it is important to identify the various aetiological factors in the occurrence of the various types of cutaneous vasculitis. The patterns and the various aetiologies of cutaneous vasculitis in Kerala is not well documented in the existing literature. MATERIALS AND METHODS The present study is a cross-sectional descriptive study of patients with a clinical diagnosis of cutaneous small vessel vasculitis admitted in Medicine and Dermatology Wards of Calicut, Government Medical College during January 2013 to December 2013. A detailed history and clinical examination of patients along with histopathological examination of skin biopsy was done. RESULTS Out of the 70 cases of cutaneous vasculitis studied, idiopathic cutaneous small vessel vasculitis was the most common type followed by Henoch-Schonlein purpura. The most common aetiology identified was drugs followed by infections. No aetiological factor was identified in 42.8% of the cases. CONCLUSION An aetiological association could be found in 57.8% of cases. The causes identified include drugs, infections, malignancy, connective tissue disorder associated, chronic systemic diseases and Behcet’s disease in decreasing order of frequency.

Congenital cutaneous candidiasis: A rare and unpredictable disease

Directory of Open Access Journals (Sweden)

Sujit A Jagtap

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.

Primary Cutaneous Carcinosarcoma of the Basal Cell Subtype Should Be Treated as a High-Risk Basal Cell Carcinoma.

Science.gov (United States)

Bourgeault, Emilie; Alain, Jimmy; Gagné, Eric

2015-01-01

Cutaneous carcinosarcoma is a rare primary tumor of the skin, characterized by biphasic epithelial and mesenchymal differentiation. Due to the limited number of cases reported, there is no consensus regarding treatment and prognosis. Some authors suggest that cutaneous carcinosarcomas should be viewed as aggressive tumors, with ancillary imaging used to evaluate potential metastatic disease. Other reports demonstrate an indolent disease course, especially with epidermal-type cutaneous carcinosarcomas. We report a case of cutaneous carcinosarcoma, which we treated with electrodessication and curettage following a shave biopsy. The tumor had an epithelial component resembling a basal cell carcinoma and a fibrosarcomatous stroma. At 1-year follow-up, our patient did not show evidence of recurrence or metastasis. Our case suggests that a cutaneous carcinosarcoma with an epithelial component composed of basal cell carcinoma can be regarded as a high-risk nonmelanoma skin cancer. © The Author(s) 2015.

Inscribing Authority: Female Title Bearers in Jewish Inscriptions

Directory of Open Access Journals (Sweden)

Carrie Duncan

2012-02-01

Full Text Available This paper investigates representations of gender in the material culture of the ancient synagogue. The pertinent data are numerous dedicatory and funerary inscriptions linking individual Jews, men and women, with titles seemingly associated with leadership in Late Antique synagogues (ca. 200–600 CE. Bernadette Brooten’s influential 1982 monograph argued against the prevailing tendency to characterize these titles as indications of power, authority, and responsibility when associated with men but as meaningless flattery when applied to women. She suggests that synagogue titles denote power, authority and responsibility on all title bearers equally, both men and women. I question the continued utility of proffering female title-holders as enumerable examples of powerful women rescued from their forgotten place in history. Using theoretical insights developed by historians Elizabeth Clark and Gabrielle Spiegel, this paper will engage a comparative analysis with the work of Riet van Bremen and Saba Mahmood to develop new methods of conceptualizing women’s authority in early Jewish communities. I propose that viewing women’s synagogue titles as culturally constructed representations allows for a fruitful inquiry into how women’s titles were used by male-dominated synagogue communities in their self-articulation and public presentation of Judaism.

2007-01-01

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

He, Yong; Ma, Chelsea; Fung, Maxwell; Fitzmaurice, Sarah

2017-07-15

Sporotrichosis is a subcutaneous mycotic infection caused by Sporothrix schenckii, a group of common saprophytes of soil, plants, and organic debris. Disseminated forms may be seen in the setting of immunosuppression and are typically treated initially with intravenous lipidized amphotericin B. We report an unusual case of a 65-year-old woman who developed disseminated cutaneous sporotrichosis with extensive facial involvement in the absence of a known primary inoculation. Her cutaneous lesions completely resolved after treatment with intravenous posaconazole without amphotericin B.

Psoriasis is a common chronic inflammatory disease of the skin. We sought to characterize and compare the cutaneous microbiota of psoriatic lesions (lesion group), unaffected contralateral skin from psoriatic patients (unaffected group), and similar skin loci in matched healthy controls (control group) in order to discern patterns that govern skin colonization and their relationship to clinical diagnosis. Using high-throughput 16S rRNA gene sequencing, we assayed the cutaneous bacterial communities of 51 matched triplets and characterized these samples using community data analysis techniques. Intragroup Unifrac β diversity revealed increasing diversity from control to unaffected to lesion specimens. Likewise, principal coordinates analysis (PCoA) revealed separation of the lesion samples from unaffected and control along the first axis, suggesting that psoriasis is a major contributor to the observed diversity. The taxonomic richness and evenness decreased in both lesion and unaffected communities compared to control. These differences are explained by the combined increased abundance of the four major skin-associated genera (Corynebacterium, Propionibacterium, Staphylococcus, and Streptococcus), which present a potentially useful predictor for clinical skin type. Psoriasis samples also showed significant univariate decreases in relative abundances and strong classification performance of Cupriavidus, Flavisolibacter, Methylobacterium, and Schlegelella genera versus controls. The cutaneous microbiota separated into two distinct clusters, which we call cutaneotypes: (1) Proteobacteria-associated microbiota, and (2) Firmicutes-associated and Actinobacteria-associated microbiota. Cutaneotype 2 is enriched in lesion specimens compared to control (odds ratio 3.52 (95% CI 1.44 to 8.98), P microbial community structure in psoriasis patients are potentially of pathophysiologic and diagnostic significance.

An accurate and complete pathology report is critical for the optimal management of cutaneous melanoma patients. Protocols for the pathologic reporting of melanoma have been independently developed by the Royal College of Pathologists of Australasia (RCPA), Royal College of Pathologists (United Kingdom) (RCPath), and College of American Pathologists (CAP). In this study, data sets, checklists, and structured reporting protocols for pathologic examination and reporting of cutaneous melanoma were analyzed by an international panel of melanoma pathologists and clinicians with the aim of developing a common, internationally agreed upon, evidence-based data set. The International Collaboration on Cancer Reporting cutaneous melanoma expert review panel analyzed the existing RCPA, RCPath, and CAP data sets to develop a protocol containing “required” (mandatory/core) and “recommended” (nonmandatory/noncore) elements. Required elements were defined as those that had agreed evidentiary support at National Health and Medical Research Council level III-2 level of evidence or above and that were unanimously agreed upon by the review panel to be essential for the clinical management, staging, or assessment of the prognosis of melanoma or fundamental for pathologic diagnosis. Recommended elements were those considered to be clinically important and recommended for good practice but with lesser degrees of supportive evidence. Sixteen core/required data elements for cutaneous melanoma pathology reports were defined (with an additional 4 core/required elements for specimens received with lymph nodes). Eighteen additional data elements with a lesser level of evidentiary support were included in the recommended data set. Consensus response values (permitted responses) were formulated for each data item. Development and agreement of this evidence-based protocol at an international level was accomplished in a timely and efficient manner, and the processes described herein may

Human immunodeficiency virus-positive secondary syphilis mimicking cutaneous T-cell lymphoma.

Malignant syphilis or lues maligna is a severe form of secondary syphilis that was commonly reported in the pre-antibiotic era, and has now reemerged with the advent of the human immunodeficiency virus (HIV) epidemic. However, the characteristic histopathological findings of malignant syphilis remain controversial. The aim of this case report was to clarify the clinical and histopathological findings of HIV-positive malignant secondary syphilis. A Japanese man in his forties complained of fever, skin lesions, headache, and myalgia without lymphadenopathy during the previous 4 weeks. The skin lesions manifested as erythematous, nonhealing, ulcerated papules scattered on his trunk, extremities, palm, and face. Although the skin lesions were suspected to be cutaneous T-cell lymphomas on histological analyses, they lacked T-cell receptor Jγ rearrangement; moreover, immunohistochemical analyses confirmed the presence of spirochetes. The patient was administered antibiotics and anti-retroviral therapy, which dramatically improved the symptoms. On the basis of these observations of the skin lesions, we finally diagnosed the patient with HIV-associated secondary syphilis that mimicked cutaneous T-cell lymphoma. The patient's systemic CD4+ lymphocyte count was very low, and the infiltrate was almost exclusively composed of CD8+ atypical lymphocytes; therefore, the condition was easily misdiagnosed as cutaneous lymphoma. Although the abundance of plasma cells is a good indicator of malignant syphilis on skin histological analyses, in some cases, the plasma cell count may be very low. Therefore, a diagnosis of malignant secondary syphilis should be considered before making a diagnosis of primary cutaneous peripheral T-cell lymphoma or lymphoma associated with HIV infection.

2008-04-01

Previous small reports suggested the role of ultraviolet (UV)-B in the management of cutaneous lichen planus. To summarize our experience with UVB in a relatively large study group looking specifically into predictive factors for complete response and the long-term relapse rates. A retrospective analysis of 50 patients with generalized cutaneous lichen planus, treated by broad or narrow band UVB. Seven and 43 patients were treated by broad and narrow band UVB, respectively. Complete response was achieved in 70% and 85% of those were still in remission after a median of 34.7 months. The complete response rate and the need for higher cumulative exposure doses were not influenced by sex, age, skin type, presence of additional diseases, failure of previous treatment or disease duration. This is a retrospective non-randomized analysis of a usually self-limiting disease. UVB is a safe and efficient treatment option for generalized cutaneous lichen planus.

Transformation of a Cutaneous Follicle Center Lymphoma to a Diffuse Large B-Cell Lymphoma—An Unusual Presentation

Directory of Open Access Journals (Sweden)

J. Dias Coelho

2010-01-01

Full Text Available Primary cutaneous follicle center lymphoma (PCFCL is characterized by a proliferation of follicle center cells in the skin. A definitive diagnosis is frequently delayed because of difficulties in interpretation of the histopathologic findings. It has an excellent prognosis with a 5-year survival over 95% and its risk of transformation has not been established. We describe a case report of man with a gastric diffuse large B-cell lymphoma (DLBCL referred to our clinic because of nodules in the back that had gradually developed over a period of 10 years. A biopsy performed 3 years before was interpreted as reactive follicular hyperplasia. A new skin biopsy revealed a diffuse large B-cell lymphoma and immunoglobulin heavy chain gene rearrangements from the initial skin biopsy (PCBCL and the DLBCL gastric biopsy were studied by polymerase chain reaction and an identical clonal rearrangement was detected which was highly suggestive of a transformation lymphoma.

Full Text Available Mycobacterium chelonae is a rapidly growing mycobacterium found in water and soil that can cause local cutaneous infections in immunocompetent hosts but more frequently affects immunocompromised patients. Typically, patients will present with painful subcutaneous nodules of the joints or soft tissues from traumatic inoculation. However, exhibiting a sporotrichoid-like pattern of these nodules is uncommon. Herein, we report a case of sporotrichoid-like distribution of cutaneous Mycobacterium chelonae in a patient with systemic lupus erythematosus on significant immunosuppressive medications. Clinicians treating immunocompromised patients should be cognizant of their propensity to develop unusual infections and atypical presentations.

Primary cutaneous follicle center lymphoma is an indolent primary cutaneous B-cell lymphoma originating from the follicle center cells, composed of a combination of centrocytes (small and large cleaved cells) and centroblasts (large noncleaved cells) with a follicular, follicular/diffuse, or diffuse growth pattern. Lesions are mostly located on the head, neck and trunk. A case is presented of a 56-year-old male patient with primary cutaneous follicle center lymphoma, with lesions involving the skin of the back, shoulders, presternal area and right forearm. As the patient presented a disseminated cutaneous form of the disease that involved several anatomical regions, complete work-up was followed by superficial fractionated radiotherapy of eight fields in VI expositions, with total irradiation dose of 1400 cGy upon the following fields: right and left pectoral region, left and right shoulders, right suprascapular region, and proximal third of the right forearm. Total irradiation dose applied upon each field for the lesions located on the left and right side of the back was 1500 cGy. This therapy resulted in significant reduction of visible tumor. The patient was regularly followed up on outpatient basis for 12 months of radiotherapy, being free from local recurrence and systemic spread of the disease

Cytodiagnosis of cutaneous metastasis from renal cell carcinoma: A case report with review of literature

2011-01-01

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.

Abnormal pigmentation within cutaneous scars: A complication of wound healing

Directory of Open Access Journals (Sweden)

Sarah Chadwick

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.

Hair and Scalp Changes in Cutaneous and Systemic Lupus Erythematosus.

Cutaneous and systemic lupus erythematosus (SLE) commonly involves the hair and scalp. Alopecia can result from direct activity of disease on the scalp or from the state of physical stress in the form of telogen effluvium. Discoid lupus erythematosus and lupus panniculitis/profundus are known to cause scarring alopecia, while accumulation of recent studies has shown that non-scarring alopecia in SLE may have different subtypes, comprising lupus erythematosus-specific and lupus erythematosus-nonspecific changes on histology. This review aims to summarize the clinical pattern, trichoscopic, histopathological, and direct immunofluorescence features of different types of alopecia in cutaneous and systemic lupus erythematosus, as well as exploring their relationship with SLE disease activity.

Delayed diagnosis of xanthogranulomatous pyelonephritis in a quadriplegic patient with uncontrolled cutaneous fistula

Abstract Rationale: Xanthogranulomatous pyelonephritis (XGP) is a chronic destructive granulomatous inflammation that is characterized by urinary tract obstruction and invasion of the renal parenchyma. Although rare, XGP can lead to fatal complications, including perinephric inflammation, psoas abscess, and cutaneous fistula. Patient concerns: A quadriplegic patient initially presented to the hospital with a chronic open wound and cutaneous fistula. Diagnoses: Abdominal computed tomography revealed a renal obstructing stone and enlarged right kidney with a perinephric fluid collection that communicated with the cutaneous fistula. Interventions: The patient underwent a right nephrectomy at the department of urology. Outcomes: Two months after surgery, the patient was clinically well with no discharging fistula. Lessons: The XGP accompanied by complications requires an immediate evaluation and early diagnosis. In this case, the diagnosis was delayed because the state of quadriplegia rendered no symptoms of XGP. PMID:29480882

Full Text Available PPolycystic ovary syndrome is the most common endocrine abnormality that affects reproductive-aged women. Diagnostic criteria of polycystic ovary syndrome have been established by different societies in recent years, and hyperandrogenism remains as one of the main criteria for diagnosis. Cutaneous manifestations of hyperandrogenism include hirsutism, acne and androgenic alopecia and are commonly observed in women with polycystic ovary syndrome. The major determinants of cutaneous manifestations are increased production of androgen and increased tissue availability. Cutaneous manifestations of hyperandrogenism are cosmetic problems, which produce significant emotional distress and psychological morbidity. Treatment includes a combination of combined oral contraceptives, antiandrogens, insulin sensitizers, gonadotropin releasing hormone agonists, topical medications, and cosmetic procedures. The diagnosis, management, and treatment approaches are described in detail in this review.

Chronic zosteriform cutaneous leishmaniasis

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.
