Neuroblastoma is the most common extracranial solid tumor of infancy.
- It is an embryonal malignancy of the sympathetic nervous system arising from neuroblasts (pluripotent sympathetic cells).
- In the developing embryo, these cells invaginate, migrate along the neuraxis, and populate the sympathetic ganglia, adrenal medulla, and other sites.
- The patterns of distribution of these cells correlates with the sites of primary neuroblastoma presentation.
