A leiomyoma is a noncancerous (benign) tumor made up mostly of smooth muscle cells. It is called an intestinal leiomyoma when the tumor is located in the intestinal tract. Usually, these tumors cause no symptoms, and they are found when a person has an upper GI endoscopy or colonoscopy for another reason. Rarely, these tumors can cause bleeding, obstruction or perforation of the gastrointestinal tract. If this happens, the tumor will need to be surgically removed.
