Hemangiomas are rare vascular tumors. They most commonly appear in the small bowel, as well as the colon and the rectum. Here, we report two cases of male patients who were admitted to our hospital for low rectal painless bleeding, misdiagnosed of hemorrhoid bleeding. Colonoscopy reported vascular tumors in both cases, which we surgically removed.
