Abstract
- Renal oncocytoma is an epithelial tumor of the kidney with a particularly good prognosis and is composed entirely of uniform packets of eosinophilic granular cells so-called 'Oncocytic cells' The cytoplasm of the oncocytoma cells is packed with mitochondria and contains few other organelles. At present time 4 cases have been reported in Korean literature without any identifiable angioinvasive lesions. We report a case of renal oncocytoma associated with angioinvasion that was suspected preoperatively and confirmed by pathologic examination including electron microscopy postoperatively. The pathology, diagnosis and treatment of this uncomrnon entity is discussed.
