A Case Report of Castleman's Disease of the Neck

Castleman's disease was originally described as a localized mediastinal lymph node enlargement characterized by angiofollicular hyperplasia and intrafollicular capillary proliferation, with surgical removal of mass the only treatment required. It has been divided into two distict histologic types. The hyaline-vascular type is more common and characterized by small hyaline-vascular follicles and interfollicular proliferation. The plasma-cell type is occurred less frequent and more likely to present with constituitional symptoms. It commonly involves the mediastinal and pulmonary lymph nodes, with neck involvement in only 15% to 20% of cases. We report two cases of hyaline-vascular type of Castleman's disease located in the neck area with references to recent literature.
