title: Chromosomal anomaly and malformation syndrome with abdominal polyorchidism.
abstract: We describe a neonate who presented with multiple severe malformations including polyorchidism. To our knowledge this is the second case reported with ipsilateral testes located intra-abdominally. Chromosomal studies in cases of polyorchidism have been reported previously only once and the patient exhibited a normal karyotype. Our patient had a chromosome 21 long arm deletion. Interestingly, a trisomy 21 patient has been reported with agonadism. We suggest that genes on chromosome 21 may have some role in gonadal development.
