Abstract
A 12 year old girl with a diagnosis of Kikuchi-Fujimoto´s disease is presented. The patient was referred with a history of 2 months of fever, bilateral cervical adenopathy, weight loss of 5 kg and malaise. There was no response to antibiotic therapy and laboratory studies excluded other aetiologies. A cervical lymph node biopsy showed diffuse necrosis, immunoblasts, histiocytes and absence of neutrophils. The patient’s evolution was favorable with disappearance of the fever by 3 months and regression of the adenopathy. We emphasize the importance of the differential diagnosis of persistent cervical adenopathies associated with prolonged fever.
