A Case Report of Schwannoma in the Rectum

Abstract

Schwannomas of the digestive tract are very rare, especially in the colon. Recently we experienced a case of rectal schwannoma. A 76-year-old male visited our clinic with the chief complaint of constipation since about a year before. The patient was preoperatively diagnosed as having sub-mucosal tumor in the rectum by Ba-enema, colonofiberscope and CT scanning of the pelvic cavity. The tumor was excised by trans-sacral approach, and was 8.5×6.0×4.0cm in dimension with kidney-like shape. Then the tumor was pathologically diagnosed as schwannoma.
The patient is alive healthy without any evidence.
