Abstract
A 63-year-old woman took further examination because of constipation in our hospital. Brium-enema and colonoscopy revealed a semipedunculated polyp with whitish color and smooth surface in the rectum. A polyp was resected by endoscopic polypectomy and diagnosed as angiomyolipoma histologically, which was consisted of three different components in the submucosa : blood vessels, smooth muscle bundles and adipose tissue. Angiomyolipoma is a benign hamartoma which usually occurs in the kidney with tuberous sclerosis. To our knowledge, this is only the fifth colonic angiomyolipoma without tuberous sclerosis reported in the international literature.
