전대장에 걸쳐 침범한 해면 혈관종 1례

Cavernous hemangioma of the colon is a rare disease. It mostly affects young patients with recurrent painless rectal bleeding. Complete surgical excision with a sphincter saving procedure is the best therapeutic option. A 25-year-old man referred to our hospital because of a chronic anemia and recurrent painless rectal bleeding. In esophagogastroduodenoscopy, there was gastric erosion. In colonoscopy, there were multiple submucosal vessel dilatations on whole colon. Prominent submucosal vessel was noted on cecum and rectum suspicious for cavernous hemangioma. Biopsy was not performed because of the risk of bleeding. Abdomen computer tomography (CT) showed bowel wall thickening in rectum and colon. Multiple small aggregated cystic lesions in omentum and mesentery were seen. Multiple calcifications in the rectum were noted, a finding compatible with phleboliths. We recommended surgery but patient refused and now he is followed up in our outpainet clinic without complication. Cavernous hemangioma is a rare disease but clinicians should be cautious about the occurrence of this malformation in young patients with recurrent rectal bleeding. Suspicion and knowledge of this disease would reduce the misdiagnosis and mismanagement.
