To report a case of lacrimal gland stone initiated by an eyelash.

A 31-year-old woman presented with foreign body sensation, pain, and conjunctival injection in the lateral palpebral conjunctiva of her right eye over 6 months in duration. The physical examination revealed a small, firm nodule at the lateral canthal area. The excisional biopsy was performed, and the mass was a concretion that contained an eyelash in the center. During one-year follow-up, the patient showed no signs of recurrence or complication after excision.

Although rare in occurence, eyelashes may be the initial nidus for lacrimal gland stone formation.
