A case of Kikuchi’s disease after extraction of a mandibular third molar

Abstract

We report a case of Kikuchi’s disease that developed after extraction of a mandibular third molar. A 16-year-old girl visited our hospital because of bilateral gingival pain of the mandibular third molar region. After bilateral extraction of the mandibular third molars, she had bilateral painful submandibular and cervical lymphadenopathy with fever.

　Under local anesthesia, a biopsy of the cervical lymph nodes was performed. Histopathological examination showed proliferation of lymphocytes and histiocytes, apoptotic bodies, and a necrotic lesion. A definitive diagnosis of Kikuchi’s disease was made. The symptoms responded to treatment with prednisolone. There was no sign of recurrence for 8 months.
