Bilateral orbital Kimura's disease in a young Asian man.

A 16-year-old Asian man adolescent presented with bilateral eyelid swelling with multiple palpable mass lesions, which waned after treatment with corticosteroids but waxed after medications were discontinued, for about 1 year. He was otherwise healthy except that bilateral postauricular lymphadenopathy had developed for about 9 years. Laboratory study revealed peripheral eosinophilia with an elevated IgE level. The tumor masses of the left orbit were completely excised through an incision similar to that used in blepharoplasty, which gave good cosmetic results. Postoperative computed tomography scan showed no residual tumor mass in the left orbit but contralateral homogeneous soft-tissue mass lesions around the lacrimal gland and extending deep into the orbit, between the superior and lateral rectus muscles. Pathology reported numerous lymphoid follicles with active germinal centers and extensive lymphocyte and eosinophil infiltration, which characterize Kimura's disease (KD). The tumor mass in the right orbit was also excised during a second elective surgery 10 days later. No evidence of recurrence was noted after follow-up for 7 months. KD of the orbit is rare and usually occurs in middle-aged to elderly Asian men but can also be present in young adolescent. Complete excision with simultaneous blepharoplasty gives satisfactory cosmetic results.
