Abstract

Oncocytomas are tumors characterized by large, eosinophilic epithelial cells with abundant mitochondria that form ductular or glandular spaces. While these tumors have been described in other organs, those of the ocular adnexa occur infrequently, with the caruncle being the most common site of involvement. Conjunctival oncocytomas are extremely rare and are believed to arise from the ductal elements of the lacrimal gland proper and the accessory lacrimal glands of the conjunctiva. We describe the clinical and histological features of a case of an oncocytoma presenting as an atypically located superior fornix mass in a 78-yearold female, with a review of the literature.
