a 33-year-old, male, black race, HIV patient came to the clinic for presenting a prolonged febrile syndrome and lymphadenopathy in the neck region. With the administration of local anesthesia and sedation, adenopathies excision was performed and a histiocytic-necrotizing lymphadenitis or Kikuchi-Fujimoto disease was diagnosed.
