ABSTRACT
We describe a case of fine needle aspiration cytologyof renal angiomyolipoma which was not associated with the clinical complex of tuberous sclerosis and was incidentally found. It was a solitary lesion and the clinical impression before needle aspiration was renal cell carcinoma. The aspirated specimen showed mature fat cells, clusters of renal tubular epithelial cells and sheets of pleomorphic smooth muscle cells with fibrillary cytoplasm. The nuclei of smooth muscle cells varied in size and shape. Since the treatment of renal angiomyolipoma differs from that of renal cell carcinoma, the preoperative cytological diagnosis is of great value.
