I'm on a roll this morning … another one from The Lancet:

Neuroblastoma, the most common extracranial solid tumour in children, originates in cells of the neural crest and is found mainly in the adrenal gland but may also be found anywhere along the paravertebral sympathetic chain in the chest or retroperitoneum. It is the most common neoplasm in infants and the leading cause of cancer deaths in children aged 1-4 years

This paper is an excellent case report of a 2 year old with nonspecifi findings. It's a good reminder of the constellation of symptoms that should cause one to think of Neuroblastoma.
