Abstract |
|
Gastric carcinoma showing the features of a submucosal tumor (SMT) is extremely rare. The incidence of this type of tumor has been reported to be 0.1∼0.63%. We report two cases of advanced gastric carcinomas showing the features of SMT. A 58-year-old man visited our hospital with a melena. An endoscopic examination revealed a 3.0 cm sized protruding lesion on the posterior wall of the gastric antrum. Most of the tumor surface was covered with normal mucosa and ulceration was observed in the center. Although the histological diagnosis could not be obtained prior to surgery, a gastrectomy was performed due to the high risk of malignancy. The tumor was diagnosed histologically as a lymphoepithelioma-like carcinoma. The other patient was a 64-year-old man with the chief complaint of epigastric discomfort. An endoscopic examination revealed a SMT like lesion with a central ulceration and hard coated exudate in the high body of the stomach. The microscopic examination revealed a poorly differentiated vimentin-positive adenocarcinoma. Unfortunately, he died from the disease two months later.
