Congenital solitary eyelid trichoepithelioma.

Trichoepitheliomas are unusual, benign tumors of hair follicle origin. They may present in children and adults as acquired lesions on the body and face, but they rarely involve the eyelids. Solitary trichoepitheliomas have not previously been reported in infants. We present a first report of congenital solitary eyelid trichoepithelioma in an infant and review the classification of trichoepitheliomas.
