A variation of Perlman's syndrome of the pancortical type is reported in a male neonate whose parents were cousins. The patient was the product of a 35-week pregnancy, the Apgar score was 3, and the patient died of respiratory failure one hour and 12 minutes after delivery. Autopsy revealed bilateral diffuse nephroblastomatosis, pancortical type, associated with malformations (usually facial), congenital anomalies of the heart, hepatosplenomegaly, pancreatic islet cell hyperplasia, bilateral cryptorchidism, and hyperflexibility of the left knee joint. Renal immunohistochemical investigations revealed positive bindings with peanut and soybean agglutinins and epithelial membrane antigen along the luminal surface of the epithelium in the moderately differentiated tubules, but not in blastoma or primitive epithelium.
