Abstract
The patient was a 70-year-old woman. An esophagogastroduodenoscopy (EGD) performed for preoperative screening prior to sigmoid colon cancer removal revealed a protruded semi-pedunculated lesion on the lower posterior wall of the cardia. Biopsy specimens from the apex of the lesion were histologically diagnosed as moderately-to well-differentiated tubular adenocarcinoma, although specimens obtained from the base of the lesion were found to be non-neoplastic. Endoscopic treatment was then scheduled after her colorectal surgery, but EGD performed 3 and 7 months later did not show the presence of a lesion. EGD performed 15 months later, however, revealed type 0-IIc cancer at the site where the protruded lesion was originally identified. The cancer was radically excised utilizing ESD. We report here a case of early-diagnosed gastric cancer that showed a change in morphology from type 0-I to type 0-IIc, which could be followed up chronologically.
