[A case of focal carcinoma of the stomach found eight years after diagnosis of atypical epithelium].
An 80-year-old man showed depressive change (IIc-like lesion) in the aggregated lesion of hemisphere nodules about eight years after diagnosis of atypical epithelium in the lesser curvature of the stomach. Carcinoma was strongly suspected by the biopsy specimen from the depressive lesion. In the resected specimen, carcinoma was present in the depressive lesion. It is sometimes difficult to distinguish atypical epithelium from carcinoma by endoscopic findings and biopsy specimens. So, in addition to being alert to gross changes of the lesion, it is very important to obtain biopsy specimens with a view to morphological changes of the lesion.
