Intrarenal teratoma in a newborn child.

A case of intrarenal teratoma in a newborn child is reported. The scarcity as well as the clinical and radiological signs of this lesion are emphasized and the difficulties to distinguish it from a nephroblastoma are analyzed. Solid intrarenal tumours in the infant and the newborn child are in nearly all cases nephroblastomas. All other types of solid tumours (benign or malignant) are exceptional. This induces us to report the present case.
