In most cases, it is identified by colonoscopy as a yellowish sub epithelial nodule, and has no associated symptoms. This tumor of the colon occasionally produces symptoms, which may be associated with large lesions. The main symptoms are abdominal pain, changes in bowel habits, and lower digestive tract bleeding. Treatment can be performed via colonoscopy or surgical approach. The objective is to report a case of a large, symptomatic giant colorectal lipoma of unusual location (sigmoid colon), and of the treatment performed.
