An angiomyolipoma is a mesenchymal neoplasm of the tumor and is composed of a varying heterogeneous mixture of blood vessels, smooth muscles, and adipose cells. Extra-renal angiomyolipomas are rarely seen and are most commonly found in the liver. Angiomyolipomas of the small intestine are extremely rare. We report the case of a 32-year-old man who had an ileal angiomyolipoma and who clinically presented with weakness and abdominal pain. A computed tomography scan of the abdomen showed a massive lesion, and segmental resection of the small intestine was performed. In the microscopic examination of the material that was sent for pathological evaluation, a tumor that included a cystic dilated vascular structure, adipose tissue, and muscular tissue extending from the serosa to the mucosa was seen. On immunohistochemical staining, various regions of the tumor were stained positive by actin, desmin, vimentin, CD31, CD34, and D2-40. With these histopathological findings, the patient was diagnosed with angiomyolipoma of the small intestinal mesentery.
