Preoperative diagnosis of bilateral renal oncocytoma by needle aspiration cytology. A case report.
The cytohistologic and ultrastructural findings in a case of bilateral renal oncocytoma diagnosed by needle aspiration cytology are presented. This case appears to be the first reported example in which the preoperative needle aspiration cytologic diagnosis of bilateral renal oncocytoma was made due to the presence of characteristic tumor cells that were seen singly or in small clusters with rounded polygonal shapes and abundant eosinophilic granular cytoplasm. The preoperative diagnosis of bilateral oncocytoma permitted a timely decision as to the appropriate management in this case.
