title: Renal medullary carcinoma: ultrastructural studies may benefit diagnosis.
abstract: Renal medullary carcinoma is a recently described highly aggressive malignancy that in most instances exhibits a constellation of clinical and light microscopic features sufficiently distinctive to enable a quick and confident diagnosis. Presented are three examples where, because of unusual elements in the clinical presentation, electron microscopic examination proved beneficial in establishing the diagnosis.
