We report a rare case of gastrointestinal stromal tumor (GIST) arising from cecal intussusception. A 61-year-old man admitted for abdominal pain and a jelly-like stool was found in ultrasonography and computed tomography to have intussusception caused by a protruding tumor of the right colon. Colonoscopy showed a hard spherical mass with erosion in the cecum. Benign tissue found in a tumor biopsy necessitated laparoscopy-assisted iliocecal resection. Histopathologically, H&E staining showed fascicular proliferation of spindle cells that, together with positive immunological staining for c-kit and CD34, yielded a diagnosis of uncommitted GIST.

Key words
