Carcinoma de células escamosas cutâneo-invasivo - relato de caso / Invasive cutaneous squamous cell carcinoma - Case report

O carcinoma de células escamosas cutâneo é resultante da proliferação maligna dos queratinócitos. Costuma surgir da evolução de lesões precursoras, mas pode crescer espontaneamente na pele normal ou cronicamente inflamada. O carcinoma de células escamosas invasivo corresponde à segunda forma mais comum de câncer da pele não melanoma e representa 20% de todas as neoplasias cutâneas. Este trabalho relata um caso clínico de carcinoma de células escamosas cutâneo, rapidamente progressivo e com metástases regionais, que mesmo com a ressecção completa e esvaziamento ganglionar, apresentou pouca resposta terapêutica e evoluiu a óbito.

Cutaneous squamous cell carcinoma (SCC) results from malignant proliferation of keratinocytes. It usually arises from the development of precursor lesions, however it may grow spontaneously on normal or chronically inflamed skin. Invasive SCC is the second most common type of non-melanoma skin cancer and accounts for 20% of all cutaneous neoplasms. The present paper reports a clinical case of cutaneous SCC, rapidly progressive and with regional metastases, which, even after complete resection of the tumor and regional lymph nodes, showed little therapeutic response and evolved to death.

Ocular manifestations of psoriasis / Manifestações oculares observadas em pacientes com psoríase

ABSTRACT Purpose: We aimed to report the ocular manifestations observed in patients with psoriasis. Methods: Patients were included and referred to our ophthalmology clinic from dermatology clinics of Universidade do Estado do Pará between October 2013 and August 2014. Clinical interviews were conducted to identify relevant epidemiological data, clinical features, and treatment details, and data were recorded using the same protocol. Subsequent dermatological examinations were performed and disease severity was rated using the Psoriasis Area and Severity Index and the Dermatological Life Quality Index. Complete eye examination was conducted, including visual acuity, biomicroscopy, tonometry, fundoscopy, Schirmer I test, tear breakup time, rose bengal staining, ocular surface disease index, and glaucoma tests. Results: In total, we included 43 patients with psoriasis and 86 controls. Patients with psoriasis had statistically higher incidences of dry eye (16.28%), likely dry eye (32.56%), and blepharitis (16.28%). Furthermore, the rose bengal and ocular surface disease tests were more abnormal in patients with psoriasis (p<0.05). Conclusions: Patients with psoriasis should undergo regular eye exams, regardless of risk factors, to monitor for the progression of symptomatic or asymptomatic ocular manifestations.

RESUMO Objetivos: Relatar as manifestações oculares observadas em pacientes com psoríase atendidos no Ambulatório de Dermatologia da X e encaminhados ao Y, no período de outubro de 2013 a agosto de 2014. Métodos: A amostra foi constituída por um grupo composto por 43 pacientes com psoríase e um grupo controle com 86 pacientes sem psoríase. Foi realizada uma entrevista clínica com dados epidemiológicos, aspectos clínicos da doença e terapia empregada, sendo todas as informações registradas em protocolo próprio. Posteriormente, realizou-se o exame dermatológico, no qual foi avaliado o índice de gravidade da Psoríase por área (PASI) e índice dermatológico de qualidade de vida (DLQI), e o exame oftalmológico completo, incluindo: Acuidade Visual, Biomicroscopia, Tonometria, Fundoscopia, Teste de Schirmer I, Tempo de Ruptura do Filme Lacrimal (TBUT), rosa bengala, índice de doença da superfície ocular (OSDI) e exames para glaucoma. Resultados: Observou-se que nos pacientes com psoríase houve frequência estatisticamente maior de envolvimento ocular, como olho seco (16,28%), provável olho seco (32,56%) e blefarite (16,28%). Além disso, os valores do rosa bengala e do OSDI apresentaram-se mais alterados nos pacientes com psoríase (p<0,05). Conclusão: Dessa forma, sugere-se que esses pacientes realizem exames oftalmológicos periódicos, já que as manifestações oculares podem progredir sem sintomatologia e ocorrer independentemente de fatores de risco.

Evaluation of cases of pemphigus vulgaris and pemphigus foliaceus from a reference service in Pará state, Brazil

BACKGROUND: Pemphigusis a bullous, rare and chronic autoimmune disease. There are two major forms of pemphigus: vulgaris and foliaceus. Epidemiological data and clinical outcome in patients diagnosed in the Brazilian Amazon states are still rare. OBJECTIVES: To study the occurrence of the disease during the study period and analyze the epidemiological profile of patients, the most common subtype of pemphigus, and the clinical evolution of patients. METHODS: Retrospective analysis of medical records of hospitalized patients with pemphigus foliaceus and pemphigus vulgaris in the period from 2003 to 2010 in Dermatology Service of Hospital Fundação Santa Casa de Misericórdia do Pará, Belém, Northern Brazil. RESULTS: We found a total of 20 cases of pemphigus during the study period, 8 of which were of foliaceus pemphigus and 12 of vulgaris pemphigus. Pemphigus foliaceus had the predominance of male patients (75%), showed satisfactory clinical evolution, and was characterized by absence of pediatric cases. Pemphigus vulgaris affected more women (66.7%), showed mean hospital stay of 1 to 3 months (50%), and there were three cases of death (25%). The prescribed immunosuppressive drugs included prednisone with or without combination of azathioprine and/or dapsone. Sepsis was associated with 100% of the deaths. CONCLUSIONS: The occurrence of the disease is rare, there are no familiar/endemic outbreaks in the sample. Evolution is usually favorable, but secondary infection is associated with worse prognosis. The choice of best drugs to treat pemphigus remains controversial. .

Tissue immunostaining for factor XIIIa in dermal dendrocytes of pityriasis alba skin lesions

BACKGROUND: Pityriasis alba affects 1% of the world population and about 9.9% of the children in Brazil. However, its etiology remains uncertain. OBJECTIVE: The objective of the present study was to evaluate the immunoexpression of factor XIIIa in dermal dendrocytes of skin lesions of pityriasis alba. METHOD: Twenty patients with pityriasis alba and 20 patients with atopic dermatitis underwent biopsy. The dermal dendrocytes marked by factor XIIIa were counted by means of immunohistochemical analysis. RESULTS: The mean amount of dermal dendrocytes found in the patients with pityriasis alba was 2, whereas in the patients with atopic dermatitis it was 4, with a statistically significant difference between them. A cutoff point of 3 cells/square inch was established to differentiate pityriasis alba from atopic dermatitis, with 80% sensibility and 90% specificity. CONCLUSION: We believe that pityriasis alba and atopic dermatitis should be considered different clinical forms within the spectrum of atopic disease, in which sun radiation plays an important role by modulating the progression of the disease. .

Clinical, epidemiological, and therapeutic profile of dermatophytosis

BACKGROUND: The cutaneous mycoses, mainly caused by dermatophyte fungi, are among the most common fungal infections worldwide. It is estimated that 10% to 15% of the population will be infected by a dermatophyte at some point in their lives, thus making this a group of diseases with great public health importance. OBJECTIVE: To analyze the clinical, epidemiological, and therapeutic profile of dermatophytosis in patients enrolled at the Dermatology service of Universidade do Estado do Pará, Brazil, from July 2010 to September 2012. METHOD: A total of 145 medical records of patients diagnosed with dermatophytosis were surveyed. Data were collected and subsequently recorded according to a protocol developed by the researchers. This protocol consisted of information regarding epidemiological and clinical aspects of the disease and the therapy employed. RESULTS: The main clinical form of dermatophyte infection was onychomycosis, followed by tinea corporis, tinea pedis, and tinea capitis. Furthermore, the female population and the age group of 51 to 60 years were the most affected. Regarding therapy, there was a preference for treatments that combine topical and systemic drugs, and the most widely used drugs were fluconazole (systemic) and ciclopirox olamine (topical). CONCLUSION: This study showed the importance of recurrent analysis of the epidemiological profile of dermatophytosis to enable correct therapeutic and preventive management of these conditions, which have significant clinical consequences, with chronic, difficult-totreat lesions that can decrease patient quality of life and cause disfigurement. .

Psoriasiform Keratosis - Case report

Psoriasiform Keratosis is a rare clinic entity. The etiopathogenesis remains unknown and the disease is characterized by a solitary, scaly or keratotic papule, or plaque mainly located on the extremities. Histopathological features closely resemble those of psoriasis. We report the case of a 70-year-old woman presenting a solitary and asymptomatic keratotic plaque, located on the back of the left leg, unresponsive to topical corticosteroids. We performed an excisional biopsy and histopathology was consistent with psoriasiform keratosis.
