Granular cell tumor rarely affects the gastrointestinal tract. The symptoms are often unspecific and the diagnosis is reached accidentally by colonoscopy. We report the case of a 42-year-old patient diagnosed with granular cell carcinoma of the colon based on an incidental finding in colonoscopy, who was treated successfully by endoscopic excision of the tumor.
