[Kikuchi disease: Evolution during outbreaks and its response to antimalarial treatment].

Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis, is a syndrome characterized by the presence of usually painful cervical lymphadenopathy with fever and night sweats. It is a rare clinical entity that mainly affects young Asian women, although it found worldwide. It is a benign and self-limiting condition; however, its importance lies in its differential diagnosis with other clinical entities such as lymphoma or histiocytoma. We present a case of Kikuchi-Fujimoto disease, with special emphasis on its clinicopathological significance and its evolution during outbreaks. Antimalarial therapy causes remission and we discuss the use of hydroxychloroquine for reoccurring cases.
