Kimura's disease presenting with intraparotid and neck nodes: A case report and review of literature.

Kimura's disease (KD) is a rare chronic inflammatory disorder of unknown etiology. The purpose of this article is to increase the awareness of clinicians regarding KD presenting with intraparotid and neck nodes which can mimic various inflammatory and neoplastic conditions. A 22-year-old man presented with a slow-growing left parotid swelling for 3 years. Ultrasound and computed tomography showed multiple enlarged intraparotid and neck nodes. Fine needle aspiration results showed lymphoid tissue hyperplasia. A diagnosis of KD was based on characteristic histopathological findings after a superficial parotidectomy in conjunction with peripheral eosinophilia. KD should be included in the differential diagnosis especially in young Asian men with slow-growing lesions and peripheral eosinophilia. Cytology by fine needle aspiration is useful to exclude malignancy but the results may be inconclusive. Surgical excision is best for definitive histopathological diagnosis, and has been the mainstay of treatment of KD.
