Abstract
A 67-year-old male, who was operated upon for carcinoma of the stomach 6 years ago and for carcinoma of the sigmoid colon 1 year ago, underwent colonoscopy, which revealed a semipedunculated polyp in the distal ileum in a distance of approximately 10 cm from the ileocecal valve. The surface structure of the polyp was the same as the surrounding normal mucosa. Endoscopic polypectomy was performed, and the retrieved material, measuring 10×6×6mm was histologically diagnosed as cavernous lymphangioma. Lymphangioma is a nonepithelial benign neoplasm, and is rarely encountered in the small intestine. This case is the first one in the reported lymphangioma that has ever been treated by endoscopic polypectomy.
