Neuroblastoma masquerading as cervical lymphadenitis.

Cervical lymphadenitis is a common pediatric finding prompting medical evaluation. The most common etiologies are infectious and reactive. The location of the involved lymph node group may provide clues to the origin of the underlying pathologic process. We describe a 21-month-old boy with metastatic neuroblastoma who presented with classic findings of infectious lymphadenitis. Surgical intervention and careful examination of histopathology led to this unexpected diagnosis.
