Abstract:
The association of gastric tubular adenoma and adenocarcinoma is already well known. Then, are those two pathologic lesions merely incidentally coexisting or does the one evolve to the other? That is a longstanding controversy. Nowadays, as is the case with the colonic tubular adenoma, the hypothesis that gastric tubular adenoma may be a precancerous lesion is generally accepted. However the direct evidences are rare. We report a clear case proving the potential of direct malignant transformation of gastric tubular adenorna through the 9-year close endoscopic follow-up. The developed cancer is well differentiated, surrounded with background tubular adenoma and limited to the submucosal layer.
