[Renal oncocytoma with cystic degeneration: a case report].
A 45-year-old man was referred to our department because of a right renal mass which was incidentally found at a health screening. Ultrasound sonography, computerized tomography and magnetic resonance imaging showed a hypovascular tumor 3 cm in diameter with the fluid at the upper pole of the right kidney, implicating that the tumor was renal cell carcinoma originating from a renal cyst wall, or with central necrosis. A radical nephrectomy was therefore performed. The tumor was dark-brown and contained brown fluid. The histopathological findings showed renal oncocytoma with cystic degeneration.
