title: [Dacryolith in a lacrimal duct].
abstract: A 31-year-old woman presented with a prominent, yellowish conjunctival mass in the left temporal canthus that had persisted for 3 months despite previous puncture. Repeat incision and curettage produced an 8 mm long concretion. A histopathological examination revealed a dacryolith in the lacrimal duct. This pathology is very rare in this location but has to be considered as a differential diagnosis when patients present with prominence and discomfort in the area of the temporal canthus. The treatment of choice is resection of the dacryolith and irrigation of the lacrimal ducts with penicillin.
