Lacrimal gland sinus generated by a retained cilium: case report and literature review.

Abstract

Lacrimal gland stone(s) (LGSs) are rare and usually asymptomatic. LGSs should be distinguished from dacryoliths, as the former arise in the lacrimal gland. The aetiology of LGSs in many cases is likely related to a reaction to a hair within the palpebral lobe of lacrimal gland. Eye rubbing may contribute to the migration of the hair into the lacrimal gland. This case report describes the rare occurrence of an LGS with a central hair shaft (cilium) and associated sinus formation in a 39-year-old male presenting with persistent redness of, and discharge from the right eye for 4 weeks. Examination revealed a sinus opening onto the inferonasal surface of the palpebral lobe of the right lacrimal gland. The patient was treated with surgical excision of the sinus, with rapid and complete resolution of his symptoms.
