A Case of Kimura Disease in the Left Postauricular and Neck Region.

This case involved a 21-year-old male patient who was admitted due to having a lump behind the left ear that had been present for 2 years and had gradually increased in size for over a year. This was accompanied by palpable hard masses on the same side of the neck. Laboratory tests indicated an elevated eosinophil count, and magnetic resonance imaging confirmed the "string-of-beads" sign in the left cervical lymph nodes. Fine-needle aspiration cytology prior to surgery revealed reactive lymphoid hyperplasia with eosinophils. Ultimately, surgical excision confirmed the diagnosis of Kimura's disease. Following glucocorticoid treatment, the patient was monitored, and no new masses were detected during 7-months follow-up period.
