【 摘 要 】
ABSTRACT 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.
