A case of leiomyoma of the rectum is reported. A 66-year-old woman was admitted to our hospital with the chief complaints of anal discomfort and bleeding. Barium enema, rectoscopy, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a submucosal tumor in the rectum, and surgery was carried out under a diagnosis of suspected leiomyoma. Transsacral resection of the tumor was performed under general anesthesia. The tumor was 4.0×4.0×5.2 cm in size with a daughter nodule (2.0×3.0×3.0 cm). The cut surface of the solid tumor was white. The histological diagnosis was leiomyoma. As distinction between benignancy and malignancy is often difficult in this disease and cases of recurrence, metastasis and malignant transformation have been reported, and therefore more adequate follow-up studies are needed.

Key words
