 We assessed the clinical usefulness of conventional endoscopy in the diagnosis of PG type protruded colorectal carcinoma. It is useful to observe endoscopic findings, such as the presence of depression, nodule on nodule and heterogeneity of color for the differential diagnosis of adenoma or carcinoma. The study of endoscopic findings, such as the presence of remarkable depression, observation of expansive appearance, and conversing folds at the circumference of the lesion is important for the differential diagnosis of Tis-T1a carcinoma or T1b carcinoma. In cases when we cannot confirm the depth, other diagnostic modalities, such as NBI observation or pit pattern observation should be used for establishing the diagnosis.
