title: Hepatic angiomyolipoma and intramural small intestinal schwannoma: a coincidence or a relationship?
abstract: We report a case of hepatic angiomyolipoma associated to a small bowel schwannoma in a 40-years old woman. Both lesions were asyntomatic. Histologically, hepatic angiomyolipoma showed oncocytic features and scanty adipose tissue, the tumor cells expressed desmin, smooth muscle actin, S-100 protein and HMB45. The tumor cells of intramural small intestinal mass were positive for S-100 protein and GFAP and negative for CD117, CD34 and desmin. To the best of our knowledge, no case of hepatic angiomyolipoma has been previously reported in association with intestinal schwannoma.
