Abstract

Mixed epithelial and stromal tumor (MEST) is a rare neoplasm of the kidney, affecting mostly women at menopausal age. While few cases of malignant transformation have been described in the literature, MEST is usually considered a benign tumor with minimal risk of local recurrence or distance metastases. The current study presents a case of a 18‑year old male patient with a cystic tumor of the left kidney incidentally diagnosed on magnetic resonance imaging of the heart performed for other reasons. The patient underwent a partial nephrectomy, with perioperative course being uneventful. The pathology report revealed MEST of the kidney. No local recurrence nor disease progression have been observed in the patient during the one‑year follow‑up period. The present case report is evidence that may help in developing guidelines on the management of patients with benign renal masses.
