Castleman's disease as an unusual cause for dysphagia and dyspnea in a pediatric patient.

Castleman's disease is a very rare entity in pediatric population and its presentation in the neck is scarcely described in the literature. We present the case of a 10-year-old-girl with an expanding neck mass over several months causing dysphagia and dyspnea. Surgical excision of the mass was performed and the analysis revealed unicentric Castleman's Disease. This is the second largest reported case of neck pediatric CD in the literature, and it presented with a symptomatology that differs from the other cases described. This fact highlights the need to include CD in the differential diagnosis of pediatric neck masses.
