[Necrotizing histiocytic lymphadenitis (Kikuchi-Fujimoto disease) in a 7-year-old girl]. / Linfadenitis histiocitaria necrotizante (enfermedad de Kikuchi-Fujimoto) en niña de 7 años.

Kikuchi-Fujimoto's disease is a rare self-limited condition of young adults that usually involves the cervical lymph nodes and is associated with fever, rash and some haematological alterations. Diagnosis is based on characteristic pathologic findings that permit differentiation of this disease from lymphoma, systemic lupus erythematous and infectious lymphadenopathies. We describe a case of 7 year-old female presenting with cervical localization of Kikuchi-Fujimoto's disease. To our knowledge, this case results the earliest affection of this disease. Our proposal with this article is to remind the pediatricians and pediatric surgeons of this poorly recognized entity when children ask for cervical masses and fever.
