A Case of Angiomyolipoma of the Colon Manifested by Intussusception / 대한소화기내시경학회지

ABSTRACT

Angiomyolipomas are a form of mesenchymal hamartoma that consists of blood vessels, smooth muscle cells, and mature fat cells. The vast majority of these tumors occur in the kidney. Extrarenal angiomyolipomas are extremely rare and have been reported in the liver, nasal cavity, vagina, spermatic cord, skin, and mediastinum. We report a case of symptomatic angiomyolipoma manifestated caused by colonic intussusception. A 67-year-old male was admitted because of lower abdominal pain that began 10 days prior. Abdominal computed tomography showed intussusception, and colonofiberscopic finding showed a lumen filled with a smooth surfaced pedunculated mass in the left side colon. The patient underwent a partial segmental resection of the sigmoid colon. I report a case of angiomyolipoma that was confirmed by the pathology findings.
