Cilia are normally found at the eyelid margin, while ectopic cilia are one or more lash follicles appearing in an abnormal position within the eyelid. We herein report two cases of cilia located in the palpebral conjunctiva. A 31-year-old female and a 46-year-old male presented with ectopic cilia in the superior palpebral conjunctiva. Histopathological study of the excised ectopic cilia and related lesions showed the cilia-related lesion to be located in the epithelial pit that contains goblet cells, which is consistent with the crypts of Henle. The hair follicle was surrounded by granulation tissue, while a dermal papilla and a hair matrix, which are known to produce hair follicles, did not exist in the excised tissue. While anterior ectopic cilia are congenital, ectopic cilia in the palpebral conjunctiva may be acquired, and these aberrant cilia are associated with crypts of Henle and chronic inflammation.
