A very rare localization of kikuchi-fujimoto disease: parotid gland

Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare benign disorder characterized by necrotizing lymphadenitis, which was independently defined by Kikuchi and Fujimoto in 1972. This disease of unknown etiology is most common in young women aged 20–30 years. In Kikuchi-Fujimoto disease, lymph node involvement most commonly occurs in the cervical region. In this study, we present a 29-year-old female patient who presented to our clinic with swelling of the right parotid gland, underwent right superficial parotidectomy after she was thought to have parotid gland tumor, and was diagnosed with Kikuchi-Fujimoto disease in a histopathologic examination. This case is important because of the very rare localization of Kikuchi-Fujimoto disease in the parotid gland, and to date, less than 10 cases have been reported in the literature.
