 We evaluated x-ray findings of 24 superficial esophageal cancers subclassified according to the depth of cancer invasion as follows: ep; those confined to the epithelium, m1; those limited within the upper half of the lamina propria mucosae (lpm), m2; those invading the lower half of lpm, and m3; those involving the lamina muscularis mucosae. On the x-ray examination, ep cancers were visualized as faintest barium shadows with unclear border, and marginal irregularity was very hard to point out. Density of barium shadow became uneven in cases of m1 cancer, and marginal irregularity and the border of lesion became clearer as cancer invades deeper layer. From the radiographical point of view, it is useful to regard ep and m1 cancers as one category, and subclassify esophageal intramucosal cancer as m1, m2, m3.
