Ectopic cilia in a 14-year-old boy

Ectopic cilia is a very rare condition in human beings, usually presented as a tuft of densely grouped hair on the lateral quadrant of the upper eyelid or conjunctival surface of the eyelid. The embryologic origin of this anomaly is unknown, and few cases have been recorded in literature. In most cases, it causes no apparent medical morbidity but is treated by surgical excision because of its cosmetic aspect. We report a 14-year-old boy with ectopic cilia with approximately 20 hairs occurring as single and grouped hairs pattern emerging from anterior surface of eyelid. Positive history of the same anomaly in his paternal grandfather demonstrates evidence of an inherited genetic disorder.
