Misdiagnosed recurrent multiple Kimura's disease: A case report and review of the literature

Abstract

Kimura's disease (KD) is a rare condition, with only a few cases reported to date, mainly in Asian patients. We herein present the case of a 48-year-old man with KD who presented with recurrent masses in the right parotid gland and neck region over a 15-year period. The masses were not accompanied by pain, or significant functional or neurosensory dysfunction. The results of the laboratory tests revealed an increased eosinophil count and markedly elevated serum IgE levels. On magnetic resonance imaging examination, a widespread abnormal signal was detected in the area of the lesions; the contrast-enhanced scan revealed inhomogeneous enhancement, with partial involvement of the sternocleidomastoid muscle and the parotid gland. The patient underwent surgical resection of the right parotid and neck masses, and the postoperative pathological examination revealed eosinophilic hyperplastic lymphogranuloma, also referred to as KD. This presented case and review of the relevant literature aim to improve our understanding of KD in order to increase the accuracy of diagnosis, reduce the misdiagnosis rate and ensure proper treatment of this rare disease.
