Case description (by case creator):

Renal tumor from a 48 year old male. The tumor was 7.3cms in diameter and had a grey spongy morphology. It is composed of cysts of varying sizes. These are lined by a single layer of tumor cells. these are variously cuboidal, columnar or on occasion hob-nailed. The cytoplasm is eosinophilic and faintly granular. Nuclei are centrally placed and although showing minimal pleomorphism do have prominent single nucleoli. Mitoses are rare.
