Malignant melanoma is a melanocyte-derived neoplasm and accounts for 5 % of skin neoplasms. Ninety five percent of melanomas appear on the skin and less than 3 % are metastasic melanoma without primary tumor evidence. In the gastrointestinal tract, most of cases of melanoma are metastasic. Primary gastrointestinal melanoma appears mostly in anorectal area followed by the esophageal area. Primary gastric melanoma is a very rare tumor, and there are very few cases reported in scientific literature. This is the report of a male patient with gastric melanoma as first sign of disease and a review of the present condition of the illness.

Keywords : melanoma; gastric; metastasis; primary.
