Abstract

The eosinophilic vacuolated tumor (EVT) of the kidney is a newly identified and pathological emerging entity. In this case report, EVT diagnosed due to a partial nephrectomy performed for a suspicious kidney mass in a 47-year-old patient is presented. A review of the literature and this case indicates that EVT, also called high-grade oncocytoma, does not show clinically aggressive behavior. However, in case of clinical suspicion, tumors with this oncocytic morphology should be treated with nephron-sparing treatment methods, considering that they may be hybrid malignancies.
