[Parotiditis viral infection associated with Kikuchi-Fujimoto disease. Review of 1 case].

Kikuchi-Fujimoto disease or necrotizing histiocytic lymphadenitis is a self-limited process of lymphatic system that affects more frequently young women. Fever and adenopathy, often cervical, are typical. Diagnosis is fundamentally based on the affected lymph node biopsy, since laboratory data are often normal. It's a very rare entity in Spain, being more frequent in Oriental countries. It's a benign evolution process, with a spontaneous healing in some weeks or months. This is the reason because of this disease could be infradiagnosed. It's very important the differential diagnosis with malignant lymphomas, because Kikuchi-Fujimoto disease doesn't need any treatment.
