The surface of cancerous mucosa in 30 surgically resected cases of early gastric cancer (22 differentiated and 8 undifferentiated adenocarcinoma) was observed through a video microscope. The mucosal surface showed characteristic findings of a pit pattern, composed of elevations and depressions of the surface, as previously reported when a dissecting microscope was used. The pit patterns of the cancerous mucosa were classified into five types under 200 × magnification: oval or round (type I), tubular or slightly branching (type II), irregular sulcus (tupe Ill), mesh‐like (type IV) and non‐structural or destroyed (type V). Most differentiated cancers had type I to 1V pit patterns, in contrast with undifferentiated cancers which mostly had a type V pit pattern. Our observations suggest that a video microscope is useful to observe magnified gastrointestinal mucosal lesions and to recognize the characteristic features of the surface such as the pit pattern.
