Herein we report a case of epithelioid angiomyolipoma of the kidney which is a rare subtype of angiomyolipoma. A 68-year-old man without a history of tuberous sclerosis complex (TSG) was referred to our department with a 40 × 84 mm left renal tumor incidentally detected by computed tomography. Computed tomography demonstrated a left renal heterogeneous mass which was enhanced at the early phase and washed out at the late phase. A tumor thrombus was seen extending into the main renal vein. No metastatic disease was evident. Thus, on the diagnosis of renal cell carcinoma, the patient underwent a left radical nephrectomy. Pathological examination showed that this tumor was composed predominantly of epithelioid cells, with a few blood vessels and adipose tissue and was diagnosed as epithelioid angiomyolipoma. He shows no disease progression for 6 months after the operation.
