Solitary ulcer syndrome of the rectum presenting with full-circumferential elevation is relatively rare in Japan. We recently encountered one such case. The patient was a 48-year-old male who visited our clinic with the chief complaint of mucous stool. Because a full-circumferential elastic-firm mass was palpable just above the anus, barium study and rectal endoscopy were performed and revealed a lesion, resembling a rectal carcinoma type 2´lesion, about 4 cm proximal from the anal verge. The affected area was poorly demarcated, and a white coat was observed on the mass surface. Based on characteristic histological findings of fibromuscular obliteration, the condition was diagnosed as solitary ulcer syndrome of the rectum and the patient was conservatively treated because he refused an operation because of diverse features, there has been confusion as to the concept and the information about this disease entity. For physicians with sufficient knowledge of this condition, its diagnosis is easy. It is a benign disease, so not to perform over surgery should kept in mind.
