[Solitary ulcer of the rectum].

The Author reports a case of solitary ulcer of the rectum. The most likely pathogenetic hypothesis seems to be linked to hypertonia of the fasciae of the puborectal muscle and the consequent traumatic and ischaemic attacks on the mucosa of the rectal ampulla anterior wall. Diagnosis of solitary ulcer of the rectum is essentially a differential diagnosis versus ulcerated carcinoma and the various inflammatory and infectious ulcerative diseases of the rectum. The rapid evolution of the reported case towards complete cure occurs in only 6% of cases, whereas chronic evolution or the rise of complications is characteristic.
