title: Unicentric Castleman's disease: a surprising neck mass.
abstract: BACKGROUND
  We present the case of a 36-year-old female with a three-week history of a pulsatile, tender mass in the anterior triangle of the neck.
  
  
  METHODS
  Radiology demonstrated that this was a vascular tumour deep to the sternocleidomastoid muscle.
  
  
  RESULTS
  Pre-operative embolisation and complete surgical resection was performed. Histology revealed Castleman's disease.
  
  
  CONCLUSIONS
  Unicentric hyaline vascular Castleman's disease is an unusual cause of neck mass. Surgical resection remains the best chance for cure in unicentric disease. Long term follow-up is necessary as the risk of subsequent malignancy exists.
