Oncocytoma of the Eyelid

Abstract

Purpose: To report a case of oncocytoma of the eyelid.Case summary: A 70-year-old male visited the ophthalmic clinic, complaining of a mass on his right lower eyelid that had grown steadily in size over the period of 1 year. At the time of his visit, his best-corrected visual acuity was 0.8 in the right eye and 0.8 in the left eye. The eyelid mass had a shape similar to that of a conjunctival nevus, and there was neither pain nor discharge. The eyelid mass was excised under local anesthesia. The mass biopsy presented as oval polygonal cells rich in eosinophilic granules in the cytoplasm. Based on this finding, the patient was diagnosed with oncocytoma of the eyelid. The patient has been under follow-up without further treatment or recurrence. Conclusions: Oncocytoma of the eyelids is rare and has not been reported in Koreans; however, very rare but aggressive forms have been reported. Thus, it is necessary to make an accurate diagnosis through biopsy and close follow-up.
