Abstract Of all the therapeutic options available in Dermatology, few of them have the history, effectiveness, and safety of phototherapy. Heliotherapy, NB-UVB, PUVA, and UVA1 are currently the most common types of phototherapy used. Although psoriasis is the most frequent indication, it is used for atopic dermatitis, vitiligo, cutaneous T-cell lymphoma, and cutaneous sclerosis, among others. Before indicating phototherapy, a complete patient assessment should be performed. Possible contraindications should be actively searched for and it is essential to assess whether the patient can come to the treatment center at least twice a week. One of the main method limitations is the difficulty that patients have to attend the sessions. This therapy usually occurs in association with other treatments: topical or systemic medications. Maintaining the regular monitoring of the patient is essential to identify and treat possible adverse effects. Phototherapy is recognized for its benefits and should be considered whenever possible.

RESUMO A endometriose ocorre em cerca de 10% das mulheres em idade reprodutiva, é histopatologicamente definida pela presença de tecido glandular endometrial e/ou estroma fora da cavidade uterina. A principal localização cutânea é o umbigo. A endometriose cutânea primária é rara e subdiagnosticada. Deve ser suspeitada na presença de nódulo eritemato-violáceo com tendência a sangramento, especialmente durante o período menstrual, mesmo na ausência de cirurgia abdominal anterior ou história de endometriose pélvica. A ressecção cirúrgica é o tratamento de escolha. A avaliação ginecológica é recomendada, visto que a associação com a doença pélvica ocorre em 26% dos casos de endometriose cutânea. Relatamos caso de paciente sem história de cirurgias abdominais e/ou endometriose, com nódulo violáceo em cicatriz umbilical com um ano de evolução, com sangramento durante o período menstrual e após traumas.

ABSTRACT Endometriosis occurs in about 10% of women of reproductive age. It is histopathologically characterized by the presence of endometrial glandular tissue and/or stroma outside the uterine cavity. The main cutaneous site is the umbilicus. Primary skin endometriosis is rare and underdiagnosed. It should be suspected in the presence of an erythemato-violaceous nodule with a bleeding tendency, especially during the menstrual period, even in the absence of previous abdominal surgery or history of pelvic endometriosis. Surgical resection is the treatment of choice. Gynecological evaluation is recommended, since the association with pelvic disease occurs in 26% of cases of skin endometriosis. We report a case of a violaceous nodule on an umbilical scar showing bleeding during menstruation, which evolved over a year following trauma, in a patient with no history of abdominal surgeries and/ or endometriosis.

RESUMO Introdução: A fototerapia é uma modalidade terapêutica empregada para tratamento de várias dermatoses. Consiste em exposição à radiação não ionizante, classificada em UVA ou UVB segundo seu comprimento de onda. Material e Métodos: Efectuámos um estudo observacional, transversal e descritivo no setor de fototerapia do Serviço de Dermatologia de um hospital universitário com o objectivo de avaliar os dados epidemiológicos e o grau de satisfação dos doentes. Resultados: Foram incluídos 51 indivíduos, 69% eram do sexo feminino com uma idade média de 49 anos. As dermatoses em tratamento mais prevalentes durante a pesquisa foram: o vitiligo, com 62,5% dos pacientes, e em segundo lugar a micose fungoide, com 13,73%. Em relação ao nível de satisfação com o tratamento, mais de 90% se declararam satisfeitos/muito satisfeitos. Discussão: A prevalência de mulheres e fototipos mais baixos foi concordante com a literatura. A predominância de idosos nesse estudo corroborada com outros trabalhos e pode ser justificada pela presença de comorbidades, e assim contraindicações aos tratamentos convencionais além de maior disponibilidade de tempo do paciente. Em alguns casos a dermatose mais prevalente foi a psoríase, diferindo do nosso estudo. A segunda dermatose mais prevalente em nosso estudo foi a micose fungoide, o que difere de outros estudos nos quais a segunda dermatose mais prevalente foi a psoríase ou o vitiligo. Conclusão: Estudos como este são necessários para o planejamento tanto dos serviços que já dispõem dessa modalidade terapêutica quanto das unidades que desejam implantá-la. Nossos resultados não são integralmente convergentes com os da literatura publicada já que atualmente existem novas opções para o tratamento da psoríase.

ABSTRACT Introduction: Phototherapy is a therapeutic modality used to treat various dermatoses. It consists of exposure to non-ionizing radiation, classified as UVA or UVB according to its wavelength. Material and Methods: This is an observational, cross-sectional and descriptive study carried out in the phototherapy sector of the Dermatology Service of a university hospital with the objective of characterizing the population under treatment and their degree of satisfaction. Results: Fifty-one individuals were included of whom 69% were female, with a mean age of 49 years. The most prevalent dermatoses under treatment during the research were: vitiligo (62.5%), and mycosis fungoides (13.73%). Regarding the level of satisfaction with treatment, more than 90% declared themselves satisfied/very satisfied. Discussion: The prevalence of women and lower phototypes was consistent with the literature. The predominance of the elderly in this study corroborated by other studies may be justified by the presence of comorbidities, and contraindication to conventional treatments beside more time available for the treatment. In some cases, the most prevalent dermatosis was psoriasis, differing from our study. The second most prevalent dermatosis in our study was mycosis fungoides, which also differs from the studies found that described psoriasis or vitiligo as the second most prevalent dermatosis. Conclusion: Studies such as this one are necessary for the planning both the departments that already have this therapeutic modality and those that wish to implement it. Our results are not fully convergent with those of the literature as nowadays there are new options for the treatment of psoriasis.

Abstract A 44-year-old male patient presented with nodules that evolved with inflammation, following drainage of seropurulent secretion and ulceration. The patient had a 6 year-history of alcohol addiction and reported contact with cats. At the physical examination, the patient had skin-colored and erythematous nodules, and ulcers covered with thick, blackened crusts on the face, trunk and limbs. A culture of a nodule fluid revealed growth of Sporotrix sp. He also had pulmonary involvement and therefore the disease was classified as systemic sporotrichosis, a rare form that usually affect patients infected with HIV. Chronic alcohol abuse was considered the factor of immunosuppression for the patient.
