Abstract The last Brazilian guidelines on melanoma were published in 2002. Development in diagnosis and treatment made updating necessary. The coordinators elaborated ten clinical questions, based on PICO system. A Medline search, according to specific MeSH terms for each of the 10 questions was performed and articles selected were classified from A to D according to level of scientific evidence. Based on the results, recommendations were defined and classified according to scientific strength. The present Guidelines were divided in two parts for editorial and publication reasons. In this second part, the following clinical questions were answered: 1) which patients with primary cutaneous melanoma benefit from sentinel lymph node biopsy? 2) Follow-up with body mapping is indicated for which patients? 3) Is preventive excision of acral nevi beneficious to patients? 4) Is preventive excision of giant congenital nevi beneficious to patients? 5) How should stages 0 and I primary cutaneous melanoma patients be followed?

Abstract: The last Brazilian guidelines on melanoma were published in 2002. Development in diagnosis and treatment made updating necessary. The coordinators elaborated ten clinical questions, based on PICO system. A Medline search, according to specific MeSH terms for each of the 10 questions was performed and articles selected were classified from A to D according to level of scientific evidence. Based on the results, recommendations were defined and classified according to scientific strength. The present Guidelines were divided in two parts for editorial and publication reasons. In the first part, the following clinical questions were answered: 1) The use of dermoscopy for diagnosis of primary cutaneous melanoma brings benefits for patients when compared with clinical examination? 2) Does dermoscopy favor diagnosis of nail apparatus melanoma? 3) Is there a prognostic difference when incisional or excisional biopsies are used? 4) Does revision by a pathologist trained in melanoma contribute to diagnosis and treatment of primary cutaneous melanoma? What margins should be used to treat lentigo maligna melanoma and melanoma in situ?

BACKGROUND: Fundamentos: As onicomicoses são infecções fúngicas que representam mais de 50% de todas onicopatias e são consideradas por alguns autores a micose superficial de mais difícil tratamento. Poucos estudos foram feitos para investigar a epidemiologia da onicomicose no Brasil. OBJETIVO: Descrever perfil epidemiológico da onicomicose nos consultórios brasileiros de dermatologia. Também observar a etiologia, a freqüência da solicitação do exame micológico e a terapia empregada. MÉTODOS: Foi realizado um estudo descritivo e observacional no período de Maio a Julho de 2010. Participaram 38 dermatologistas de diferentes regiões do Brasil e foram incluídos 7852 pacientes. RESULTADOS: Dos 7852 pacientes, 28.3% apresentaram diagnóstico de onicomicose. Mulheres, maiores de 45 anos, praticantes de esportes, ou com histórico pessoal da doença, apresentaram chance maior de adquirir onicomicose. A doença foi mais frequente nos pés, sendo o hálux, o dedo mais acometido. Nas mãos, o primeiro dedo foi o mais atingido. Exame micológico não foi solicitado para todos os casos. Quando realizado, o fungo mais freqüente foi o Trichophyton rubrum. A lesão clinica mais comum foi a distal-lateral. Os tratamentos tópicos mais prescritos foram amorolfina e ciclopirox olamina, enquanto os sistêmicos foram o fluconazol e a terbinafina. CONCLUSÃO: Este estudo foi de fundamental importância para descrever o comportamento epidemiológico da onicomicose nos consultórios dermatológicos brasileiros e determinar fatores de risco, como gênero, idade, prática de esportes, antecedente pessoal de onicomicose e comorbidades. Esperamos contribuir na melhora da abordagem terapêutica e prevenção desta doença.

BACKGROUND: Onychomycosis is a type of fungal infection that accounts for over 50% of all onycopathies. Some authors consider superficial mycosis the most difficult to be treated. Very few studies have been carried out in order to assess the epidemiology of onychomycosis in Brazil.OBJECTIVE: To describe the epidemiological profile of onychomycosis in Brazilian dermatology offices and to assess the etiology of the disease, how often mycosis exams are requested, and the treatment adopted.METHODS: A descriptive, observational study was carried out between May and July, 2010. Thirty-eight dermatologists from different Brazilian regions participated in the study, and 7,852 patients with any skin diseases who had all of their nails examined were included in the study.RESULTS: Of the 7,852 patients, 28.3% were clinically diagnosed as having onychomycosis. Women over 45 years old who practiced exercises or with a personal history of the disease showed greater likelihood of having onychomycosis. The disease was most seen in the feet, and the majority of cases involved the hallux. On the hands, the index finger was the most affected. Mycosis exams were not requested for all clinically suspected cases. When exams were done, results showed that the most common fungus was Trichophyton rubrum. The most common clinical lesion was distal-lateral. The most prescribed topical treatments were amorolfine and ciclopirox olamine, while systemic treatments included fluconazole and terbinafine.CONCLUSION: This study was important to describe the epidemiological behavior of onychomycosis in Brazilian dermatology offices and to determine important risk factors, such as gender, age, practice of exercises, personal history of the disease, and comorbidities.

O tumor glômico é uma neoplasia benigna de células glômicas. Na maioria dos casos se apresenta como uma pápula solitária dolorosa na região subungueal. Relatamos o caso raro de um paciente com dois tumores glômicos sincrônicos sob o leito ungueal do mesmo dedo.

The glomus tumor is an uncommon benign neoplasm of glomus cells. In the majority of the cases it is presented as a solitary painful papule in the subungual region. We report a rare case of a patient with two individual synchronous glomus tumors under the nail bed of the same finger.
