Massive adrenal hemorrhage in neonatal neuroblastoma.

In a neonate with exsanguinating intraperitoneal bleeding admitted with a provisional diagnosis of ruptured liver due to birth trauma, laparotomy revealed the source of hemorrhage to be an adrenal neuroblastoma. This case prompted a review of cases of abdominal neuroblastoma admitted to the Neonatal Surgical Unit in Alder Hey Children's Hospital from 1953 to 1976. The features of 10 cases are presented: in three of them there was hemorrhage into the tumor. Of the 10 cases, six survived tumor free from 2 to 12 yr and there is one short-term survivor. The purpose of this presentation is to emphasize the possibility of an underlying neuroblastoma in cases of neonatal adrenal hemorrhage and also the relatively good prognosis in neuroblastoma presenting in the neonatal period.
