[A case of leiomyosarcoma of the rectum].

Leiomyosarcoma of rectum is a rather rare malignant tumour. Generally, it manifests late when pain, tenderness, rectal bleeding and obstruction occur or ulceration through the rectal mucose with bleeding or discharge occur. Rectal examination leads to the diagnosis of malignancy. The histological report confirms the type of tumor. A case of leiomyosarcoma of the rectum has been reported. Radical resection (Miles) is the treatment of choice at present. The prognosis is poor.
