Angiomyolipoma of colon: unusual presentation

Abstract

Angiomyolipomas are benign mesenchymal tumors mostly arising from the kidney. Angiomyolipoma of the colon is extremely rare. Here we report the findings of a 72 years gentleman who presented with recurrent episodes of abdominal pain and fullness of one year duration. Colonoscopy was suggestive of polypoidal lesion in the descending colon. CECT abdomen revealed a colocolic intussusception in the descending colon with lipoma as a leading point. He underwent a standard left hemicolectomy. Histopathological examination showed that the tumor of 5.7 cm in diameter included smooth muscle (spindle cell type), mature adipose tissue, and vessels, and therefore a diagnosis of angiomyolipoma was made. We believe this is the second report of colonic angiomyolipoma presenting with colocolic intussusception.
