Abstract

Choristoma is a congenital abnormal growth of tissue with components which are not characteristic of the location. Most choristomas often affect tissues of one germinal layer, mainly ectodermal layer, but complex choristoma contains two or more choristomatous tissues(ectodermal, mesodermal and rarely entodermal tissue) except lacking pilosebaceous apparatus. We experienced a case of large bilateral saccular complex choristomas including scleral and episcleral cartilage in the upper part of cornea, limbus and sclera, which was confirmed histopathologically.
