A Case of Congenital Mesoblastic Nephroma

ABSTRACT

The congenital mesoblastic nephroma is the most common renal neoplasm seen in the first few months of life. This tumor usually benign, but local recurrences and metastases have been reported, and treatment is total nephrectomy. This entity must be differentiated from Wilm's tumor so as to avoid unnecessary postoperative irradiation and chemotherapy. Recently, we experienced a case of congenital mesoblastic nephroma in female newborn infant. Diagnosis was made with physical examination, plain roentgenogram of the abdomen, ultrasonography of the abdomen and I.V.P. and confirmed with microscopic examination. A brief review of the related literature was made on this subject.
