title: Unusual location for Castleman's disease.
abstract: OBJECTIVE
  We present the first reported case of persistent, posterior triangle lymphadenopathy in a child, caused by Castleman's disease.
  
  
  METHODS
  A seven-year-old boy presented with a painless swelling in the posterior triangle of his left neck, with no compression of the surrounding structures. A histological diagnosis of Castleman's disease was made. Eventual treatment was by complete excision. At six-month follow up, there were no signs of recurrence.
  
  
  CONCLUSIONS
  The causes of persistent cervical lymphadenopathy in children are many. Most are not significant, but some are life-threatening. Castleman's disease should be considered as a possible diagnosis in persistent childhood lymphadenopathy.
