Neuroblastoma in a Child With Wolf-Hirschhorn Syndrome

Neuroblastoma is the most common extracranial solid tumor of childhood originating from sympathetic nervous system cells. Neuroblastoma has also been diagnosed in conjunction with other congenital conditions such as Hirschsprung’s disease, congenital hypoventilation disorder, and neurofibromatosis type 1. Wolf-Hirschhorn syndrome is a congenital disorder caused by microdeletion of short arm of chromosome 4 encoding MSX1gene with characteristic facial features. We describe a child with dysmorphic features, developmental delay, mental retardation who developed neuroblastoma at 2 years of age and cytogenetic analysis of blood lymphocytes revealed an interstitial deletion of 4p(15,2). To best our knowledge, this report is the first report of neuroblastoma in a child with Wolf-Hirschhorn syndrome; and the reported association may be an important clue for oncological follow-up of patients with Wolf-Hirschhorn syndrome.
