Case Report: Gastric and duodenal metastasis of malignant melanoma: a rare clinical presentation
This case underscores the potential for malignant melanoma to develop synchronous metastases in both the stomach and duodenum, even in the absence of specific GI symptoms (3, 6). It highlights the critical role of endoscopic evaluation and immunohistochemical analysis in achieving a timely diagnosis (4, 7). A high index of suspicion is warranted in patients with a history of melanoma, as GI metastases confer a poor prognosis (4, 7).
