Concurrent adrenal neuroblastoma and kawasaki disease: a report of a rare case.

Kawasaki disease (KD) is a systemic vasculitis of unknown etiology and a leading cause of acquired heart disease. It is assumed that there is an activation of the immune system by an infectious trigger in a genetically susceptible host. Neuroblastoma is the most common extracranial solid tumor in young children. It mainly originates from primordial neural crest cells that generate the adrenal medulla and sympathetic ganglia. A diagnosis of concurrent KD and neuroblastoma in a living child has been made in only one previous report. We report the second case and review the literature.
