case_images: Findings included a 20-mm pedunculated polyp with a stalk measuring 0.6 cm in length and 0.4 cm in diameter in the ascending colon (fig. 1), and an 8-mm polyp in the transverse colon removed with polypectomy and a 3-mm polyp in the ascending colon removed with biopsy forceps.

case_images: Histologically, the pedunculated ascending colon polyp revealed bland spindle cell proliferation in the submucosa (fig. 2, fig. 3).
case_images: Immunohistochemical features of colonic neurofibroma. The tumor cells are strongly positive for S100 protein immunostaining (original magnification x40).
