• 

  Fig. 1 Colonoscopic findings. (A) A 3 cm-sized, bluish-red polypoid mass was noted at the ileocecal valve. (B) The epinephrine solution diluted with normal saline was administered to the lesion. (C) A detachable snare was placed at the base of the stalk and a standard electrical snare was then used for polypectomy. (D) Hemoclips were used to prevent bleeding from the polypectomy site.

  Fig. 2 Abdominopelvic computed tomography finding. Transverse plane (A) and coronal plane (B). An ovoid and low-density mass measuring about 3.0 cm in size (arrows) was noted in the proximal ascending colon.

• 

  Fig. 3 Histopathological findings. (A) The specimen showed submucosal cystic dilation of the venous vessel associated with proliferation of the reactive focal muscle bundle (black arrow) (H&E, ×100). (B) It showed CD31-positive endothelial cells (black arrows) in the dilated blood vessels (CD31, ×400). (C) It showed D2-40-negative endothelial cells (black arrows) in the dilated blood vessels (D2-40, ×200).

  Fig. 4 Colonoscopic finding at 4 months after endoscopic polypectomy. A scar was noted at the ileocecal valve.
