Necrotizing lymphadenitis of the neck. Histiocytic necrotizing lymphadenitis is a rare cause of cervical lymphadenopathy. It is a benign, self-limiting disease whose etiology is unknown. Cervical lymphadenopathy and fever are the most important signs. Here we report a 25-year-old female presenting with complaints of fever and a painless swelling in the neck for three months. An excisional biopsy of a posterior cervical lymph node was performed, and histological evaluation revealed histiocytic necrotizing lymphadenitis. This article discusses our case of histiocytic necrotizing lymphadenitis of the neck as well as the relevant literature.
