Lymphocytoma cutis on the inguinal region: report of a rare case of benign lymphoproliferative disorder.

Lymphocytoma cutis, or benign reactive lymphoid hyperplasia, is an inflammatory skin lesion that mimics clinically and histologically malignant lymphoma. Most cases are idiopathic, but they may also be triggered by multiple factors, such as insect bites, tattoos, injections and herpes zoster. Clinically, the lesions are erythematous, soft papules, plaques or nodules, usually located on the upper limbs and face. The diagnosis is mainly based on histopathology and immunohistochemistry. Corticosteroid injections, cryosurgery, PUVA therapy, radiotherapy and surgery can be therapeutic options in cases requiring immediate treatment. To demonstrate an atypical presentation of this tumor, a case lymphocytoma skin on the groin will be reported, describing its diagnosis and treatment.

Lymphocytoma cutis on the inguinal region: report of a rare case of benign lymphoproliferative disorder

Abstract Lymphocytoma cutis, or benign reactive lymphoid hyperplasia, is an inflammatory skin lesion that mimics clinically and histologically malignant lymphoma. Most cases are idiopathic, but they may also be triggered by multiple factors, such as insect bites, tattoos, injections and herpes zoster. Clinically, the lesions are erythematous, soft papules, plaques or nodules, usually located on the upper limbs and face. The diagnosis is mainly based on histopathology and immunohistochemistry. Corticosteroid injections, cryosurgery, PUVA therapy, radiotherapy and surgery can be therapeutic options in cases requiring immediate treatment. To demonstrate an atypical presentation of this tumor, a case lymphocytoma skin on the groin will be reported, describing its diagnosis and treatment.

Occupational skin cancer: Systematic review.

OBJECTIVE: To analyze the epidemiological profile, risk factors in the workplace environment and prevention methods for professionals at risk of skin cancer. METHOD: A systematic review of articles on occupational skin cancer, published in the Lilacs, Scielo, Medline and Cochrane Library from January 1st, 2008, to December 31st, 2013, was performed. The search included the following terms: "neoplasias cutâneas" (DeCS), "exposição ocupacional" (DeCS), "epidemiologia" (DeCS) as well as the keyword "prevenção", and their equivalents in English. RESULTS: After analyzing the titles and summaries of articles, the search strategy resulted in 83 references, of which 22 articles met the eligibility criteria. DISCUSSION: We found that sun exposure is the main occupational risk factor for skin cancer, causing outdoor workers to be the most vulnerable to developing occupational skin cancer. Professionals with low levels of education and European descent are at increased risk of developing this cancer. CONCLUSION: Outdoor workers are more vulnerable to developing occupational skin cancer, estimating that professionals with low level of education and European descent are at increased risk of developing this cancer. Therefore, companies need to invest more in the health of workers by providing protective equipment and thus preventing occupational skin cancer.

RESUMO Objetivo: analisar o perfil epidemiológico, os fatores de risco no ambiente de trabalho e os métodos de prevenção dos profissionais de risco para câncer de pele. Método: foi realizada uma revisão sistemática de artigos sobre o câncer de pele ocupacional, publicados entre 1 de janeiro de 2008 e 31 de dezembro de 2013, nas bases de dados Lilacs, Scielo, Medline e Biblioteca Cochrane. A pesquisa baseou-se na intersecção dos seguintes termos: “neoplasias cutâneas” (DeCS), “exposição ocupacional” (DeCS), “epidemiologia” (DeCS) e a palavra-chave “prevenção” e seus equivalentes em inglês. Resultados: após a análise dos títulos e resumos dos artigos, a estratégia de busca resultou em 83 referências, das quais 22 artigos preencheram os critérios de elegibilidade. Discussão: a exposição solar é o principal fator de risco ocupacional para câncer de pele e os trabalhadores ao ar livre são os mais vulneráveis a desenvolvê-lo. Aqueles com baixo nível de escolaridade e ascendência europeia apresentam maior risco de desenvolver a neoplasia. Conclusão: os trabalhadores ao ar livre são mais vulneráveis a desenvolver câncer de pele ocupacional. Os profissionais com baixo nível de escolaridade e ascendência europeia apresentam maior risco de desenvolver a neoplasia. São necessários mais investimentos das empresas na saúde dos trabalhadores por meio de fornecimento de equipamentos de proteção, a fim de prevenir o câncer de pele ocupacional.

Leprosy treatment dropout: a systematic review.

BACKGROUND: Leprosy is a chronic infectious disease endemic in some undeveloped areas, and still represents a public health problem in Brazil. Therefore, the control of this endemic disease depends necessarily on the institution of correct treatment and containment of treatment dropout. This study aims to conduct a systematic review of published studies on treatment dropout of leprosy. METHODS: We conducted a systematic review of articles on treatment dropout of leprosy, published between january 2005 and april 2013, on MEDLINE and SciELO databases. The search was performed using the MeSH terms: "leprosy"; "patients dropouts" and the keywords: "leprosy, treatment" and "noncompliance, leprosy" in association, beside the equivalents in Portuguese. RESULTS: There were originally 196 references. After analyzing the titles and abstracts of articles, 20 articles were obtained and included in the final sample. DISCUSSION: Leprosy is a notifiable disease known as its disfiguring capability and the high rate of non-compliance to treatment. The low adhesion is responsible for the remaining potential sources of infection, irreversible complications, incomplete cure and, additionally, may lead to resistance to multiple drugs. Many factors are responsible for the interruption or dropout treatment: socioeconomic factors, education level, knowledge about the disease, lack of efficiency of health services, demographics, side effects of drugs, alcoholism, among others. CONCLUSION: The recent scientific literature about the subject diverge regarding the factors that most affect the dropout problem in treating leprosy patients. However, better integration between professionals and users, and greater commitment of the patient, are common points among the authors of the studies.

Multiple metastatic basal cell carcinoma with concurrent metastatic pleomorphic sarcoma in chronic lymphedema area--case report.

Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.

Linfedema crônico se manifesta pelo acúmulo de líquido intersticial por falha da drenagem linfática. A região afetada torna-se imunologicamente vulnerável e predisposta ao desenvolvimento de neoplasias. Carcinoma basocelular é a neoplasia maligna mais comum, entretanto raramente metastatiza. Sarcomas são neoplasias mesenquimais malignas, localmente agressivas e capazes de metastatizar. Apresentamos um caso raro de múltiplos carcinomas basocelulares concomitantes a sarcoma pleomórfico pouco diferenciado, metastáticos para linfonodos, originando-se em área de linfedema crônico.

Hanseníase tuberculóide em paciente com Aids / Tuberculoid leprosy in aids patient

Relata-se o caso de uma criança de oito anos, portadora de Aids, que desenvolveu hanseníase tuberculóide antes do início da terapia anti-retroviral. Apresentava lesões ulceradas nos membros, Mitsuda de 8,5mm, hipoestesia em perna esquerda, e o diagnóstico de hanseníase foi definido pela imuno-histoquímica antiproteína S-100, que mostrou fragmentos de ramos nervosos no interior dos granulomas. A incidência da hanseníase não aumentou com o advento da Aids, e não há modificações na apresentação clínica ou na resposta terapêutica nos casos de hanseníase associados à Aids. Também não se observou neste caso o desenvolvimento da reação tipo 1 como resultado da reconstituição imunológica devido ao tratamento anti-retroviral.

The authors present a 8 year-old child with AIDS who developed tuberculoid leprosy prior the beginning of the anti-retroviral treatment. The pacient presented ulcered lesions in arms and legs, the Mitsuda reaction was 8,5 mm, there was hypostesia of the left leg and the leprosy diagnosis was reached mainly supported by the anti-S100 protein immunohistochemistry staining that showed fragments of nerve branches inside granulomas. The incidence of leprosy has not increased because of AIDS. There havenÆt been changes in the clinical presentation and in the response to therapy in cases of leprosy associated with AIDS. We havenÆt also observed development of type 1 reaction in this patient resulting from restoring of the immune response after the anti-retroviral treatment.

Hanseniase tuberculoide em paciente com aids / Tuberculoid leprosy in aids patients

Os autores apresentam o caso de uma crianca de 8 anos, portadora de aids por transmissao vertical, que desenvolveu as primeiras manifestacoes da hanseniase tuberculoide, antes do inicio do tratamento anti-retroviral. As lesoes iniciais percebidas eram ulceras de bordas endurecidas, que cicatrizavam e ulceravam novamente. Nesta epoca apresentava 0,3 celulas CD4+. As lesoes permaneceram com esta evolucao ate o momento em que foram realizados os primeiros exames para confirmacao do diagnostico de hanseniase. Nesta ocasiao estava fazendo tratamento anti-retroviral, apresentava 270 celulas CD4+. Foi realizada uma biopsia da lesao cutanea. Quando retornou, as ulceras estavam cicatrizadas, podendo se notar mais nitidamente o aspecto sarcoidico das lesoes. A reacao de Mitsuda foi de 8,5mm, havia hipoestesia em perna esquerda, e o diagnostico de hanseniase foi definido, principalmente atraves da imunoistoquimica anti-proteina S100, que demonstrou fragmentos de ramos nervosos no interior dos granulomas. A incidencia da hanseniase nao aumentou com o advento da aids e tambem nao ha modificacoes na apresentacao clinica, nem resposta a terapeutica nos casos de hanseniase associado a aids. Tambem nao observamos neste paciente o desenvolvimento da reacao tipo 1, como resultado da reconstituicao imunologica em decorrencia do tratamento anti-retroviral
