Two pediatric cases of Kikuchi–Fujimoto disease (histiocytic necrotizing lymphadenitis) are reported due to its rarity. They came to clinical attention because of cervical lymphadenopathy and fever. One was diagnosed by open biopsy and the other by ultrasound-guided fine-needle aspiration biopsy. Ultrasonographic and histocytological findings are described. The importance of this entity is that it is easily confused clinically, radiologically and pathologically with malignant lymphadenopathy, especially lymphoma. Open biopsy is usually performed to obtain a definite diagnosis. However, when typical cytological findings are present, a precise diagnosis is possible and this allows clinicians to avoid unnecessary biopsies or aggressive treatment.
