Histiocytic necrotizing lymphadenitis (HNL, Kikuchi's disease) is a lymphadenitis of unknown cause, originally described by Kikuchi and Fujimoto in 1972. Because HNL has been rarely reported in the oral region, it has occasionally been misdiagnosed as oral infected disease or another disease of the neck. A 32-year-old female suffering from two painless nodules that had appeared suddenly in the left of the posterior cervical triangle visited our department. The dimensions of the nodules were 15 mm and 10 mm in diameter. There were no systemic signs or symptoms such as fatigue and fever. From the clinical view, blood examination, CT findings and MRI findings, it was difficult to make a diagnosis. Biopsy of the larger nodule was therefore done and microscopy indicated HNL. The other nodule disappeared after 2 months with no medication. Although the nodule appeared again after 1 year and 8 months, it naturally disappeared again in a month.
