- Abstract: A granular cell tumor (GCT) is a relatively rare benign tumor that has been seldom reported since Abrikossoff first described it as a granular cell myoblastoma in 1926. While GCTs can occur anywhere in the human body, they are very rarely observed in the gastrointestinal tract and are especially rare in the large intestine. Most GCTs are small and asymptomatic and are often found by endoscopy, upper gastrointestinal series, and autopsy. We report two cases in which a submucosal tumor in the cecum was accidentally discovered by colonoscopy and was subsequently removed by colon polypectomy and endoscopic mucosal resection. Immunohistochemical analysis of the samples confirmed both cases as GCT. The literature review and reports of other growths in the gastrointestinal tracts support the necessity for proper identification of GCTs within the body to differentiate them from more malignant tumors.
