Abstract
- An epithelioid angiomyolipoma is an uncommon clinicopathological variant of an angiomyolipoma. A 25-year-old man presented with a huge right renal tumor and underwent a radical nephrectomy. The pathological diagnosis was an epithelioid angiomyolipoma, which showed a positive reaction to the HMB-45 monoclonal antibody and negative to epithelial cell markers. A year later, multiple metastases developed to the liver, lungs and bones. A hepatic lobectomy was performed, and a metastatic epithelioid angiomyolipoma, from the original renal tumor, was pathologically confirmed. The case is presented with a review of the literature.
