Primary eyelid leiomyoma.

A 10-year-old white male presented with a recurrent painful nodule of the left lateral lower eyelid margin with associated madarosis. The initial pathologic diagnosis at an outside institution was reported as chalazion. The lesion was re-excised, and histopathologic examination with immunohistochemical evaluation confirmed the diagnosis of leiomyoma. This is the first reported case of primary leiomyoma originating in the eyelid.
