Stage 4S Bilateral Adrenal Neuroblastoma in a Newborn.

Stage 4S bilateral adrenal neuroblastoma presenting in the neonatal period is extremely rare. A 1-day-old male with 4Sbilateral adrenal neuroblastoma complicated by marked hepatomegaly managed by chemotherapy is being reported. The provisional diagnosis of neuroblastoma was made in the fetal life during the last trimester of pregnancy. Cardiomyopathy due to doxorubicin cytotoxicity developed over ensuing years, which is being treated.
