[Histological types of depressed early gastric cancer and roentgenographic findings].
Characteristic findings of depressed early gastric cancer were summarized by neoplastic histological type according to the roentgenographic findings as follows: Undifferentiated cancer: The depressed surface shows many irregular changes and granular shadows of various sizes. The depressed edge is clear and shows a coarse or small wavelike pattern. The mucosal folds of the stomach are often interrupted by the depressed edge or show sharp thinning. Differentiated cancer: The depressed surface shows very few irregular changes, and is rather squamous compared with undifferentiated cancer. The depressed edge is fine and shows a thornlike pattern. The margin shows spindle or low IIa-like protuberance findings. The mucosal folds show slight thickening at the margin and gradual thinning at the depressed site. Thus, the folds are rarely interrupted at the margin.
