 We describe the usefulness of esophagography for estimating the depth of cancer invasion of early esophageal carcinoma in a 66-year-old man. A superficial and protruding lesion accompanied by a slight depression (type 0-Ⅰ+Ⅱc) from the middle to the lower thoracic esophagus was detected endoscopically. Endoscopic diagnosis was carcinoma massively invading the submucosa. On the other hand, esophagography showed a well-defined contour and lower height of the protrusion than estimated by endoscopy and no deformity of the esophageal margin. Radiologic diagnosis was carcinoma with invasion confined to the muscularis mucosae (m3) below the protrusion. The resected specimen showed a 0.8×0.4 cm-sized protruding lesion accompanied by a 5.5×3.5 cm-sized slightly depressed lesion. Histological examination revealed that cancer invasion below the protrusion remained in the lamina propria mucosae (m2), but the deepest point of invasion reached into the muscularis mucosae in a small area in the slightly depressed lesion. In conclusion, for accurate estimation of cancer invasion below protruding lesions, it is necessary to observe the contour of elevation in addition to the height of the protrusion and to take note of whether or not there is deformity of the esophageal margin.
