Abstract

Schwannoma in colorectum is a rare subepithelial polyp of mesenchymal origin, which is derived from the neural sheath, and most of reported cases were removed surgically. We, herein, describe two cases of schwannoma of the cecum, which were removed by endoscopic mucosal resection. A 34-year-old man and a 62-year-old man presented with abdominal discomfort and bowel habit change. The patients were diagnosed with a subepithelial tumor in the cecum on colonoscopy and underwent endoscopic mucosal resection under a tentative impression as neuroendocrine tumor, such as carcinoid tumor. Histopathology and immunohistochemistry confirmed the colonic lesion to be a benign schwannoma.
