Congenital mesoblastic nephroma beyond infancy

Abstract

Congenital mesoblastic nephroma (CMN) is a peculiar renal tumor with a unique clinical, therapeutic, and prognostic pattern. CMN is a benign renal tumor of the neonatal period and early infancy. Although a rarity, presentations beyond infancy are also reported. Rarely, this tumor presents beyond infancy. The case report tries to highlight the fact that this tumor though rare beyond infancy should also be included in the list of differentials of childhood renal masses. It also underlines the utility of preoperative biopsy and the role of nephron-sparing surgery while dealing with such a benign etiology (considering the excellent prognosis associated with the condition).
