A Case of Oncocytoma of the Caruncle

ABSTRACT

PURPOSE: To report a case of oncocytoma of the caruncle. CASE SUMMARY: A 63-year-old woman visited our clinic due to a mass in her left caruncle that developed five months prior to admission. At the time of her visit, her visual acuity was 0.8 in the right eye and 1.0 in the left eye, and there was a small mass in her left eye. She did not have any pain, and no discharge was apparent. All blood sample results were within the normal range. Also, we did not perform any radiologic studies. We administered systemic antibiotics and excised the mass from the caruncle of her left eye. Her biopsy read 'Oval cells with cytoplasm stuffed with eosinophilic granular material'. These findings are compatible with oncocytoma of the caruncle. CONCLUSIONS: The oncocytoma of the caruncle requires regular follow-up, which differs from the treatment plans for hemangioma, nevi, and cysts.
