A CASE OF TRANSSACRALLY EXCISED TERATOMA ORIGINATING IN THE RECTUM

Abstract

A 65-year-old woman visited our hospital with the chief complaint of constipation. Barium enema examination revealed an oval tumor mass containing a round shadow of calcification in the rectum. Colorectal endoscopy also showed a tumor with hairs on the surface occupying the rectal space. The tumor, which was transsacrally excised, was 8×6×4 cm in size, had hairs on the surface, and presented osseous tissue, cysts and melanism on the cut surface. Histopathologically it was diagnosed as mature teratoma. Rectal teratoma is rare with only 40 cases having been reported to date. In the present paper, the first case known to be managed by transsacral excision is reported together tiwht a review of the literature.
