We report the case of a huge right renal tumor in a 17‐year‐old girl. Absence of fat on preoperative magnetic resonance imaging suggested renal cell carcinoma, and surgery was performed. Pathologic evaluation with HMB‐45 immunohistochemical staining conrmed the diagnosis of epithelioid angiomyolipoma. The tumor consisted predominantly of epithelioid cells, and it could easily be misidentied as a renal cell carcinoma due to the paucity of the fat component. Previous reports have suggested that epithelioid angiomyolipomas have the potential to be malignant, and thus regular postoperative surveillance is recommended. Our patient had no signs of recurrence at her most recent follow up, 12 months after surgery.
