Metastatic melanoma of the stomach: the endoscopic and roentgenographic findings and review of the literature.

A case of metastatic melanoma of the stomach is reported with illustrative endoscopic and radiographic findings. Metastatic melanoma of the stomach may present with vague gastrointestinal symptoms, abdominal pain, or gastrointestinal bleeding. A history of melanoma may not be readily obtainable. When gastrointestinal symptoms occur in a patient with known melanoma, gastric metastases should be considered. Polypoid or target lesions are frequently seen on barium x-ray study. Small bowel roentgenograms should be obtained. Endoscopy, cytologic study, brushing, and biopsy may yield the diagnosis. The prognosis is poor. Surgery should be performed only to relieve significant symptoms.
