[Hemorrhagic cyst of the kidney in the neonatal period. Apropos of 2 cases].
Two cases of haemorrhagic renal cysts in neonate are reported. Both cases were premature newborns with obstetrical difficulties and delayed tumoral syndrome. The first case was considered a solitary renal cyst. The surgical procedure was a prominent domme resection. Four years later a contralateral Wilm's tumor appeared which became bilateral in 12 months, terminating in death 3 months later. The second case is clinically and radiologically similar in the neonate period. The surgical procedure was a nephrectomy. Compared histological reading of both resection materials, allowed us to establish diagnosis of congenital cystic nephroma. Cystic wall cells were normal elements of Bolande's tumor, of which microcystic forms have been soon reported. Hypothesis in our two cases would be mesoblastic nephroma in a pure cystic form, which would allow to widen morphologic spectrum of Bolande's tumor.
