Figure 1 Endoscopic findings of the rectal tumor. A: A remarkable protrusion (Is) with slight bleeding is observed in the rectum; B: Chromoendoscopy enhances a flat elevated lesion (IIa) which is located at the base of the protrusion lesion; C: Magnified endoscopy with narrow-band imaging reveals an intense irregular micro-vascular pattern indicating the existence of carcinoma in the Is lesion; D: Magnified endoscopy shows faint vascular pattern on the IIa lesion.
