Paraneoplastic hypertension associated with renal oncocytoma: management with cryoablation.
Paraneoplastic hypertension associated with a renal oncocytoma is an unreported syndrome. We report a unique case of a patient with multidrug-resistant hypertension who was found to have a solitary renal mass. Cryoablation was performed and resulted in an immediate and dramatic decrease in blood pressure. Histologic review of intraoperative biopsy specimens revealed findings consistent with renal oncocytoma. To our knowledge, this is the first report of hypertension in the setting of a renal oncocytoma, with subsequent improvement of this paraneoplastic syndrome after cryoablation.
