 Analysis was made on the diagnosis of invasive depth of esophageal cancer from the color and macroscopic appearance by endoscopic examination of type 0-IIa, 0-1 and type 1, showing protrusion. Most protruding cancers are mixed type, accompanied by 0-IIb and 0-IIc, but the deepest lesion is occasionally located on the protruding portion. The whitey granular and whitish flat elevation of type 0-IIa is a typical feature of mucosal cancer, whereas a reddish tiny granular tumor with gentle sloping of type 0-IIa is limited to the M2 and the SM1. The flat reddish type 0-Is often invading deeply to the SM, and type 0-Ip showing reddish flat elevation with constrictor at the base has invaded to the SM. Type 1 with wide border is invading as progressive cancer of T2 and T3, and the type 1 with reddish feature and small border is limited to the SM3 and the T2 and rarely progressing to T3. Rare pathological esophageal cancers are found mostly as protruding tumors, and pseudobasal cell cancer, endocrine cancer(small cell cancer)show subepithelial growth at the tumor edge covered by normal mucosa, and carcinosarcoma is featured by polyp-like protrusion with constrictor at the base.
