 Eleven cases of m3 and sm1 carcinomas were detected and examined in our center within the last 7 years. Eight were resected by surgical procedures and three were dealt with by endoscopic mucosal resection. (1) In the morphological study, seven showed 0-Ⅱc type and only one showed Ⅱc+Ⅱa type. The latter was diagnosed as m3. (2) By the longitudinal diameter of the part affected by m3 invasion, three correctly diagnosed cases showed 3~14 mm in length (mean 7.25 mm). On the other hand, three cases misdiagnosed showed 0.5~17 mm in length (mean 5.5 mm). (3) The two cases of sm1 showed 2 mm in depth of invasion and were accompanied by m3. (4) In the radiological study, the depth of cancerous invasion was diagnosed by the frontal and lateral view of the lesion. The radiolucent area shows the thickness of the cancerous invasion and marginal irregularity shows the roughness of the cancerous surface.
