Kimura disease of the eyelid: a clinicopathologic study with electron microscopic observations.

A 70-year-old white man presented with a solitary eyelid nodule of 6 months' duration. Because lymphoma could not be excluded on the initial biopsy, the mass was completely excised. Histologic examination confirmed the diagnosis of Kimura disease, an uncommon chronic inflammatory condition. Peripheral eosinophilia was present. The patient did not have any other lesions of Kimura disease on follow-up examination. The clinical, radiologic, histologic, and electron microscopic findings of Kimura disease are discussed. To our knowledge, solitary involvement of the eyelid has not been reported previously. Kimura disease should be included in the differential diagnosis of an eyelid mass lesion.
