Solitary schwannoma of the rectum mimicking rectal cancer: report of a case and review of the literature

Abstract

A case of a submucosal tumor bulging into the rectum in an old female patient is reported. It proved to be a very rare case of rectal schwannoma, whose differential diagnosis is difficult to obtain preoperatively and optimal treatment and prognosis still uncertain. The mass was removed by means of an ultrasound device after an open anterior rectotomy. The operation was uneventful and the patient is disease free 18 months after.
