This article concerns a 25-year-old woman, with clinical symptoms of Kikuchi-Fujimoto Syndrome (KFS). The patient arrived ten days after symptom onset. She initially discovered lymphadenopathy on the right side of her neck. She had no fever, pruritus or weight loss. Fine needle aspiration biopsy indicated a lympho-proliferative disease, which was confirmed by a lymph node biopsy. KFS is histologically characterized by necrotizing lymphadenitis. The cardinal symptoms are fever, lymphadenopathy and night sweat.
