  • Abstract
  • Look Inside

 The patient was a 75 year-old woman. Five years and two months before operation, she visited our hospital with complaints of a heavy feeling in the epigastric region, nausea and anorexia. On the initial routine x-ray examination, an ulcer scar was found on the lesser curvature of the body, and then we performed endoscopy with biopsy, detecting a small protuberant atypical epithelial lesion on the posterior side of the lesser curvature.

 After about 5 years of follow up by endoscopy, biopsy and x-ray examination, however, another lesion of cancer was finally confirmed histologically just in the neighborhood of the protuberant lesion. On the resected stomach, Ⅱc type early cancer of 6.0×4. 5 cm was found located on the lesser curvature of the body. Histological study revealed well differential adenocarcinoma, limited just in the mucosal layer. Inside this Ⅱc area, an island-like lesion of 0.8 cm diameter was observed, which histologically consisted of atypical epithelium.

 Upper G-Ⅰ series, endoscopy and biopsy were performed 4, 16 and 11 times respectively in a follow up period of 5 years and 2 months. On the 11th endoscopic examination performed 4 years and 8 months after the first examination, the Ⅱc-like lesion was finally detected. Since then, however, only a diagnosis of group Ⅲ was obtained continuously on each succeeding 4 biopsy trials. And a diagnosis of group Ⅳ was established finally on the 6 th biopsy.

 When x-ray findings obtained 3 years ago (3 rd examination) were reviewed retrospectively, the lesion had been already faithfully visualized, which was strongly suggestive of Ⅱc.

 A diagnostic process of Ⅱc type early gastric cancer was reported, which was detected accidentally during a follow up of a protuberant atypical epithelium.

 During the course of long term, the cancerous lesion of Ⅱc might have developed gradually and spread superficially to such extent as to be observed endoscopically and diagnosed bioptically. The entire clinical course was 5 years and 2 months from an initial examination to a final operation.
