Kimura Disease of the Head and Neck Region.

Abstract

Objective: We analyzed the clinical characteristics and treatment results in surgical patients with a final diagnosis of Kimura disease. Patients and Methods: A total of 8 patients with a final diagnosis of Kimura disease of the head and neck region after surgery from January 2007 to December 2022 were enrolled. Results: The most common symptom was a mass in the head and neck region (n = 7), followed by incidental detection (n = 1). Multiple head and neck lesions were observed except for 1 patient with Kimura disease in the buccal space. Kimura disease could not be diagnosed in 5 patients who underwent preoperative fine-needle aspiration cytology. All patients underwent surgical resection. No major complications after surgery occurred. Six patients received steroids after surgery, with 1 patient undergoing radiotherapy as a side effect of steroid treatment. During the follow-up period, 5 patients relapsed. Of the parameters assessed, only longer symptom duration was statistically significant with relapse of Kimura disease. Conclusion: Clinicians should suspect Kimura disease based on asymptomatic masses, peripheral blood eosinophilia, and imaging examinations and make a definitive diagnosis via surgery.
