 Schwannomas of the digestive tract are rare, especially in the colon. An 86-year-old man visited at our hospital with the symptom of lower abdominal discomfort. Smooth tumor mass measuring of 30×30 mm was detected in the sigmoid colon by barium enema. Colonoscopy showed a submucosal tumor. Laparoscopic sigmoidectomy was performed with the diagnosis of submucosal tumor. Pathologic examination of the tumor revealed densely proliferated spindle cells with a slight atypical appearance. Immunohistologically, the tumor cells were positive for S-100 protein and negative for c-kit; the lesion was diagnosed as Schwannoma.
