About a rare disease misdiagnosed as malignant lymphoma or tuberculosis: Kikuchi-Fujimoto's disease.

Kikuchi-Fujimoto's disease KFD is a rare and benign cause of cervical lymphadenopathy. It is an anatomoclinical entity of unknown etiology. The confirmation of the diagnosis is always provided by histological lymph node study. The clinical picture sometimes evokes lymphoma or tuberculosis. The evolution is generally favorable with spontaneous healing after a few weeks. We report the case of a 26-year-old woman who had consulted for cervical lymphadenopathy associated with fever. The cervical lymph node biopsy concluded to Kikuch-Fujimoto's disease. The evolution was marked by rapid regression of lymphadenopathy under corticosteroid treatment.
