A Case of Congenital Mesoblastic Nephroma / 대한비뇨기과학회지

Congenital mesoblastic nephroma is relatively rare congenital disease. It occurs in the early neonatal period as an unencapsulted and locally invasive fibrous lesion. Survival following nephrectomy alone is excellent but local recurrence and metastases have been reported. Herein we present one case of congenital mesoblastic nephroma. A 13-day-old male infant admitted our hospital with chief complaint of palpable left abdominal mass. After nephrectomy, histologic diagnosis is congenital mesoblastic nephroma.
