혈변을 동반한 횡행결장의 거대 해면 혈관종 1예

Abstract

Gastrointestinal hemangiomas are not common and congenital lesion. Intestinal bleeding is the most common symptom of it. Hemangiomas were classified with capillary, cavernous and mixed type. Cavernous hemangioma is most common. Colonic cavernous hemangioma is rare and are usually arising in the sigmoid colon or/and rectum. Transverse colonic cavernous hemangioma are very rare. Gastrointestinal hemangioma is commonly developed in childhood and in young adults. Fifty eight-year-old man who complained of hematochezia was admitted. Physical examination was unremarkable. Stool occult blood was positive. Abdominal computerized tomography show normal finding. Colonoscopic examination showed giant and bluish-purple colored vascular malformation, 15 cm in length with tough bleeding, on the transverse colon. The patient underwent segmental resection of transverse colon for confirmatory diagnosis and treatment. The final pathologic diagnosis of the resection lesion was cavernous hemangioma of the transverse colon. We report a case of giant hemangioma of the transverse colon associated with hematochezia, with review of relevant literature.
