O conhecimento da frequência e das características clinicoepidemiológicas do melanoma cutâneo nas diversas regiões do Brasil é importante para avaliar a magnitude do problema e direcionar adequadamente as ações de saúde. Neste estudo, revisaram-se os dados de 55 pacientes com melanoma cutâneo atendidos em duas instituições de saúde da cidade de Manaus. Verificou-se maior frequência entre homens pardos, na oitava década de vida, com lesões do tipo melanoma acrolentiginoso nos membros inferiores, com Breslow maior que 1mm e Clark nível V.
Dermoid cysts or mature cystic teratomas are mesenchymal neoplasms most commonly found in the ovaries, but which may occur in any location along the pathways of ectodermal cell migration. They are rarely seen in the pancreas, where they show a slight preference for the pancreatic head. We report a case of dermoid cyst of the pancreas in a 69-year-old male patient, discussing the epidemiology, clinical presentation, diagnosis and treatment of this neoplasm. Since preoperative diagnosis is difficult, given its rarity in this site, it is usually diagnosed by histopathology of the specimen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
