Abstract

Here we report a case of epitholiod angiomyolipoma with cystic changes in a 42-year-old woman. Preoperative imaging studies revealed a 9.8 cm cystic tumor arising from the lower pole of the right kidney, with multiple enhancing solid components and septation diagnosed as a cystic renal cell carcinoma. The patient underwent laparoscopic radical nephrectomy. Histopathology revealed a lipid-poor angiomylipoma with epithelioid features.

Keywords: Cystic angiomylipoma; Cystic renal cell carcinoma; Epitholiod angiomyolipoma.
