RESUMO
Histiocytic necrotizing lymphadenitis is a benign disorder of the lymph node which should be differentiated from other types of lymphadenitis or malignant lymphoma. The most common presentation includes fever and cervical lym-phadenopathy .The course is invariably benign and spontaneous resolution usually occurs within 4 to 6 months. The diagnosis is confirmed by characteristic pathological findings of the involved lymph node. The involvement of the ner-vous system is known to be rare. We report two patients with histiocytic necrotizing lymphadenitis accompanied by aseptic meningitis. In one patient, both diseases developed simultaneously and in the other patient, histiocytic necrotiz-ing lymphadenitis was followed by aseptic meningitis 2 months later.
