A CASE REPORT OF SCHWANNOMA OF THE RECTUM

Abstract

Schwannomas of the digestive tract are rare, especially in the rectum. Recently we experienced a case of rectal schwannoma. A 56-year-old female was admitted to our department with the chief complaints of on coccygeal mass and flat stool. The patient was diagnosed as having an extramurally growing neurofibroma of the rectum by Ba-enema, colon fiber, CT, and needle biopsy. The operation was done.
Intraoperative frozen section diagnosis disclosed no malignancy, and simple resection of the tumor was carried out. The resected tumor, with dumbell-like shape, was pathologically diagnosed as schwanmoma. Histologically Antoni type A mixed with the type B was identified without malignancy.
