Resumo: | Noncutaneous melanoma is a rare clinical entity, and their primary or secondary nature is often difficult to establish. Few cases of primary gastric melanoma have been described in the literature. We report a case of a 55-year-old male patient with dyspepsia complaints. Esophagogastroduodenoscopy revealed a polypoid mass with blackened areas at the greater curvature of the gastric body, which was histologically compatible with melanoma; positive immunohistochemistry for S100, melan-A, and vimentin. The extensive dermatological exam did not identify a primary lesion. |

Poucos casos de melanoma gástrico primário são descritos na literatura. Relatamos o caso de um paciente do sexo masculino, 55 anos, com queixas dispépticas. A esofagogastroduodenoscopia revelou lesão polipoide com áreas enegrecidas na grande curvatura do corpo gástrico, histologicamente compatível com melanoma; imuno-histoquímica positiva para proteína S100, melan-A e vimentina. O exame dermatológico extenso não identificou lesão primária.engUniversidade Federal de Minas GeraisUFMGBrasilMED - DEPARTAMENTO DE ANATOMIA PATOLÓGICA E MEDICINA LEGALJornal Brasileiro de Patologia e Medicina LaboratorialMelanomaImuno-HistoquímicaNeoplasias GástricasMelanomaImmunohistochemistryGastric neoplasmsPrimary gastric melanoma: a case report of a rare malignancyMelanoma gástrico primário: relato de caso de uma neoplasia maligna rarainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/jbpml/a/WX9bDNNBMzxpdsBbNS4ztwJ/Raquel IdaferreiraLeonardo C.

Noncutaneous melanoma is a rare clinical entity, and their primary or secondary nature is often difficult to establish. Few cases of primary gastric melanoma have been described in the literature. We report a case of a 55-year-old male patient with dyspepsia complaints. Esophagogastroduodenoscopy revealed a polypoid mass with blackened areas at the greater curvature of the gastric body, which was histologically compatible with melanoma; positive immunohistochemistry for S100, melan-A, and vimentin. The extensive dermatological exam did not identify a primary lesion. |
