Abstract

Gastrointestinal Stromal Tumor (GIST) is a rare mesenchymal tumor of the digestive tract, mostly located in the stomach, small intestine, colon, and rarely in the rectum. Rectal GISTs are often diagnosed later than other sites. We report a case of a middle-aged male patient presenting with urinary symptoms due to a large rectal tumor that was preoperatively embolized and then surgically removed with histopathological results of high-grade malignant GIST.
