Hemangioma - Example 1
This is a 56-year-old white male patient who at a routine preventive visit showed evidence of occult blood in the stool. Patient denies any symptoms and had never observed blood in the stool.
The video recording shows a short segment of the sigmoid colon. Here, one sees two dark red to blue structures that are somewhat elevated and broad-based. These colonic hemangiomas have a diameter of about 4 to 8 mm. The remaining bowel shows no pathological changes.
Hemangiomas, which are a rare occurrence in the colon, are benign and less common than angiodysplasias. In cases in which they result in clinically relevant blood loss, endoscopic therapy in the form of argon plasma coagulation may be attempted.
