摘要

非皮肤黑色素瘤是一种罕见的临床实体，其原发或继发性质往往难以确定。文献中很少有关于原发性胃黑色素瘤的报道。我们报告一例55岁男性患者消化不良的投诉。食管胃十二指肠镜显示胃体大弯曲处息肉样肿块伴黑色区域，组织学上与黑色素瘤一致;免疫组化检测S100、黑色素a和波形蛋白阳性。广泛的皮肤检查未发现原发病变。

Primary gastric melanoma: a case report of a rare malignancy

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.
