[An atypical lacrymal cyst]

Lacrimal cysts are rarely described and must be differentiated from diseases of the lacrimal gland. We present a rare case of lacrimal cyst developed from an accessory lacrimal gland.The management consisted of excision using a tarsoconjonctivale approach.Most cysts are diagnosed from the third decade, manifested by progressive exophthalmos. It is a benign disease. However, the differential diagnosis with malignancy is not excluded. Surgical resection is desirable if tumors become symptomatic.
