| Abstract |
|
Angiomyolipoma is a common benign tumor in the kidney, composed of blood vessel, smooth muscle cells, fat and myelocomponent, but hepatic angiomyolipoma is a rare benign mesenchymal neoplasm. Radiologic findings are not specific because the composed elements are variable in proportion and distribution. Recently, we experienced a case of angiomyolipoma in a incidental tumor of the liver in a 23-year-old man with history of tuberculous pericarditis. The tumor, measuring 1.7 ×1.8 cm, was located in the segment Ⅴ of the liver. Diagnosis was aquired by fine needle aspiration biopsy under ultrasonographic guidance. Microscopically, it showed smooth muscle cells, lipocytes and blood vessels. Immunohistochemically, the tumor cells were positive for HMB-45, S-100 protein, focally positive for SMA, but negative for cytokeratin, anti-hepatocyte antigen and chromogranin.
