A case of rectal leiomyosarcoma was reported with special references. It is a relatively rare disease and to our knowledge, 80 cases have been reported so far in Japan. A 65-year-old woman was admitted to our hospital because of check up of disturbances in defecation and occasional dyschezia. In the rectal examination, tumorous mass was palpated 4 cm above the anal ring. Based on the findings of barium enema, fiberoptic endoscopy, ultrasonography, CT, endoscopic ultrasonography and angiography, myogenic tumor was suspected. For confirmation, a needle biopsy was performed through the anus. Histological examination of the biopsy specimen revealed loiomyoma. Surgical excision of the tumor was carried out through the anus. Malignancy was confirmed by histopathological examination of the resected specimen. Therefore, radical reopration was performed.
