title: Extrathoracic castleman'S disease - presenting as a neck mass.
abstract: Castleman's disease, also known as angiofollicular hyperplasia, is a disease of unsettled complexity and morbidity, usually occurs in the mediastinum and less frequently in the neck as a solitary mass and is often associated with other illnesses. Two variants have been recognized, the hyaline vascular type which is mare common and the less common plasma cell type with a third hybrid or intermediate type that shares features with both. It has been described with AIDS and Kaposi's sarcoma as well as follicular dendritic cell tumours.We report a case of Castleman's disease of the hyaline vascular type arising in the left supra-clavicular region in 41 year old male without any associated systemic illness. The neck is an uncommon location for this rare disease.
