Type 2 congenital pulmonary airway malformation and congenital nephrotic syndrome: Report of a new association

Type 2 congenital pulmonary airwaymalformation (CPAM) has been reported in association with many other congenital anomalies. To the best of our knowledge, however, an association of type 2 CPAM with congenital nephrotic syndrome has not been heretofore reported. We present the 1st report of such an association in a boy who had a prenatal diagnosis of cystic lungmalformation andwas found to have congenital nephrotic syndrome (diffuse mesangial sclerosis) at 1 month of age. A prenatal ultrasonogram had also shown oligohydramnios, and additionally the child had cleft lip and palate. There was no family history of childhood renal or pulmonary disease, and genetic testing for genes mutated in congenital nephrotic syndrome was negative.
