Abstract
Castleman's disease (giant or angio follicular lymph node hyperplasia) was first described by Benjamin Castleman in the year 1957 and was named after him. It is an uncommon lympho proliferative disorder which is localised to single lymphnode (unicentric) or multiple lymph node level systemically (multicentric).It is a very rare disorder characterised by non-cancerous growths. The most common sites of this are mainly thorax (mediastinum or lung hilum) and abdomen. It rarely occurs in cervical area. We report a case of unicentric cervical castleman's disease of neck in an 18-year-old female, who came to ENT OPD with history of right sided neck mass since 6-8 months. After thorough clinical examination and investigations, complete excision of the mass was done. Histopathological examination confirmed the diagnosis of Castleman's disease. On follow-up for one year no recurrence has been seen.
