[Conjunctivo-corneal complex choristoma. Report of an anatomoclinical study]

Complex choristomas are very rare ocular tumors. We report a case of a 3-month-old infant who was referred to us because of a left congenital conjunctivo-corneal protruding mass. Total excision removing 2/3 of the limbus was performed and replaced simultaneously by a limbal autograft. Histopathological examination of the excised choristoma revealed many pilosebaceous follicules in the conjunctival tissue, keratinized epithelium, lacrimal glands, and differentiated cartilage.
