title: [Oncocytoma of the conjunctiva].
abstract: A 72-year-old woman presented with a lesion in her right eye, which had developed over 2 years. The cherry red lesion was located in the bulbar conjunctiva in the area of the plica semilunaris. Ophthalmologic examination was otherwise normal. Differential diagnosis included a pyogenic granuloma and a hemangioma. Excision of the tumor was performed. Histological examination revealed solid nests and cords of polyhedral cells exhibiting abundant, finely granular acidophilic cytoplasm and round to oval paracentral nuclei usually containing a single prominent nucleolus. The diagnosis of oncocytoma was established. Ocular oncocytomas are rare neoplasms and are mostly found in the caruncle. A location in the bulbar conjunctiva is extremely rare and only two reports are found in the literature with both of these located in the plica semilunaris.
