Summary:A 77-year-old woman was admitted to the hospital because of melena and anemia. Digital examina-tion, pelvic CT scan and barium enema revealed a mass 6cm in diameter in the lower rectum about 2cm distal from the anal verge. We performed a Miles' operation and diagnosed the tumor as leiomyosarcoma pathologically, In the 14th month after the operation, vertebral bone metastases (Th10, L3) with lunbago were identified and she died in the 20th postoperative month. The immunohistochemical study showed that the tumor cells were positive for CD34 and c-kit and negative for SMA and S-100. The tumor was diagnosed as rectal gastrointestinal stromal tumor (GIST) finally. We report the case of rectal GIST with bone metastases that is extremely rare, together with some bibliographical comments.
