Left & Center : 64 year-old woman undergoing colonoscopy for evaluation of a palpable rectal polyp and occult bleeding. During colonoscopy, retroflexion of the instrument in the rectum revealed a pale, tan polypoid lesion which appeared to be attached at its base to an internal hemorrhoid. The lesion was surgically excised, and histologically proved to be a benign fibroepithelial polyp arising from anorectal musoca.

Right: 55 year-old man with a similar benign-appearing, bland polypoid lesion seen at retroflexion. Histology of the surgically-excised specimen revealed fibroepithelial papilloma.
