title: Granular cell tumor (myoblastoma) of the palpebral conjunctiva causing pseudoepitheliomatous hyperplasia of the conjunctival epithelium.
abstract: Granular cell tumors rarely occur in the ocular adnexal structures and only three cases have been described in which the eyelid alone was involved. I examined a patient who was, I believe, the first in whom a granular cell tumor appeared clinically as a conjunctival lesion. She was also the first patient with a granular cell tumor of the ocular adnexa to exhibit pseudoepitheliomatous hyperplasia of the overlaying epithelium, a pathologic feature associated with granular cell tumors originating elsewhere in the body.
