Rectal biopsy as a cause of rectal ulceration.
We report three patients in whom the performance of a rectal biopsy produced an ulcer that was found during a subsequent examination (two at double-contrast barium enema examinations and one at colonoscopy). In each case, the iatrogenic ulcers presented an unusual appearance and resulted in the performance of inappropriate follow-up studies.
