Neoplasia in the pediatric age range is not common. Childhood malignancies are rare, but those that occur often have the appearance of primitive "small round blue cell tumors" such as the neuroblastoma seen here. These pediatric malignancies may include:

Childhood Malignancy	Location
Leukemia / lymphoma	Blood, marrow, lymph nodes
Neuroblastoma	Adrenal, extra-adrenal ganglia
Medulloblastoma	Cerebellum
Retinoblastoma	Eye
Wilms tumor	Kidney
Ewing sarcoma	Bone
