Περίληψη:
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. (C) 2,006 The WJG Press. All rights reserved.
