title: Complex choristoma of the eyelid containing ectopic cilia and lacrimal gland.
abstract: A 2-year-old girl was born with an aggregate of ectopic cilia in the right upper eyelid that intermittently produced tears. During elective excision, the cilia were found to be clustered tightly with prominent bulb-like follicles. A separate lobe of lacrimal gland tissue was adjacent to the roots of the cilia just posterior to the orbital septum with no direct communication with the lacrimal gland. Histopathologically, the lesion contained multiple large hair follicles in the dermis with accompanying adnexal structures. Large ectopic lobules of lacrimal gland tissue also were present. Postoperatively, the child had a good cosmetic result and has remained asymptomatic over an 18-month follow-up period. To our knowledge, this is the first reported case of an eyelid choristoma containing ectopic cilia and lacrimal gland. Ectopic cilia alone is a very rare anomaly of the lashes, with only nine cases reported in the literature.
