[Single nonspecific ulcer of the rectum]

The authors report 4 cases with single, non-specific ulcer of rectum. The diagnosis, in all the cases, was made after endoscopic and histological studies. Single ulcer of rectum is for the first time reported in a pregnant woman, that necessitated the interruption of pregnancy. The ulcer could spontaneously be healed and be combined with an ulcer of duodenum. The patients with single ulcer of rectum should be under follow-up care and yearly controlled in the course of three years.
