ABSTRACT

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.


Cistos dermoides ou teratomas císticos maduros são neoplasias mesenquimais comumente encontradas nos ovários, mas que podem ocorrer em qualquer via de migração das células ectodérmicas. No pâncreas, a ocorrência é rara, sendo mais comum na cabeça pancreática. Relata-se caso de cisto dermoide do pâncreas em paciente masculino de 69 anos, discutindo-se epidemiologia, clínica, diagnóstico e tratamento dessa neoplasia, pouco suspeitada no pré-operatório devido à sua raridade nessa topografia; geralmente, é diagnosticada apenas pelo exame histopatológico da peça cirúrgica.

ABSTRACT

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.


Knowledge on the frequency and clinical and pathological characteristics of cutaneous melanoma in the different geographical regions of Brazil is important in evaluating the magnitude of the problem and in directing healthcare actions appropriately. The present study reviewed data from 55 cases of cutaneous melanoma in patients treated at two healthcare institutions in the city of Manaus, Amazonas, Brazil. Rates were higher in brown-skinned males and in individuals of 70-80 years of age. Lesions were most commonly located on the lower limbs, were of the acral lentiginous melanoma type and at advanced stages of the disease, with Breslow thickness > 1 mm and Clark level V.
