[Cervical Castleman disease in childhood: a report of two cases and a review of the literature]

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.

Cervical unicentric Castleman's disease in children

INTRODUCTION

Unicentric Castleman's disease (CD) is a rare benign lymphoproliferative disorder. A cervical location has rarely been reported in the pediatric literature.

CASE REPORT

A 13-year-old boy presented with a mass in the right neck region of 3 months' evolution. Clinical examination revealed a smooth mobile 5 cm node deep in the sternocleidomastoid muscle. The diagnosis of hyaline vascular type CD was confirmed by complete surgical excision and histopathologic examination. Postoperative course was simple, without recurrence over 1 year's follow-up.

DISCUSSION AND CONCLUSION

Cervically located CD often shows few symptoms, and is rarely suggested by a cervical mass found in children. Definitive diagnosis is histopathological. The hyaline vascular type of unicentric CD has a good prognosis after complete resection of the lesion.
