Renal epithelioid angiomyolipoma presenting clinically as renal cell carcinoma – A case report

Year: 2014

Type: article

Abstract: We describe a 22-year old female who presented with a 5-year history of a palpable, painless mass in the right flank. Computerized tomography demonstrated a solid renal mass measuring 18 cm × 13 cm with peripheral calcification, areas of vascularity and necrosis. The appearance suggested renal cell carcinoma or nephroblastoma , but percutaneous renal biopsy suggested an adrenal origin. At right radical nephrectomy , the adrenal gland was completely normal. Histology showed sheets and nests of epithelioid cells with abundant eosinophilic to clear cytoplasm, confirming a diagnosis of epithelioid angiomyolipoma (EAML), a rare mesenchymal tumor belonging to the perivascular epithelioid cell tumor family (PEComas). At 33 months followup, there was no evidence of recurrence or metastases .
