Cervical Lymphadenopathy Secondary to Kikuchi-Fujimoto Disease in a Child: Case Report

While most cases of cervical lymphadenopathy resolve with conservative management, persistent adenopathy can lead to costly investigations and invasive treatments. One cause of persistent adenopathy, as well as a variety of other associated systemic symptoms, is Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis). This rare entity can he diagnosed only by excisional biopsy on the basis of its characteristic histologic appearance. We describe a case of persistent cervical lymphadenopathy secondary to Kikuchi-Fujimoto disease in an 11-year-old girl.
