摘要
Melanoma accounts for 1-3 per cent of all malignant tumors. Except cutaneous, other less common melanomas include, among others, those in the GI tract. However, their primary or secondary nature is often difficult to establish. Referring to the stomach, scattered cases of primary melanomas have been reported in the literature. We report a case of a man with an ulcerated submucosal mass at the antrum of the stomach, manifested with dull upper abdominal pain, nausea, vomiting, fatigue and anemia. This lesion was histologically proved to be melanoma. A detailed clinical and laboratory investigation revealed no primary site elsewhere. To our knowledge, very few cases of primary gastric melanoma have been reported. Our case is the fourth ever published and the first located at the antrum of the stomach. The debate upon the primitive nature of such lesions still persists. Thus, specific diagnostic criteria have been proposed.
为所有恶性瘤的 1-3% 的黑瘤报道。除了皮肤，另外的不太普通的黑瘤包括在其它之中，那些在官方补给的道。然而，他们的主要或第二等的性质经常是困难的建立。指胃，主要黑瘤的散布案例在文学被报导了。我们在胃的窦与一个溃烂的 sub-mucosal 团报导一个人的一个案例，迟钝的上面的腹的疼痛地表明了，恶心，呕吐，疲劳和贫血症。这损害组织学地被证明是黑瘤。临床的详细说明的 A 和实验室调查没在其它地方揭示主要地点。到我们的知识，主要胃的黑瘤的很少的案例被报导了。我们的案例是第四曾经出版了，第一在胃的窦定位了。在如此的损害的原始性质之上的争论仍然坚持。因此，特定的诊断标准被建议了。
