title: A case of recurrent, grade 3 corneal choriostoma after surgical excision.
abstract: We report a case of congenital grade 3 corneal choriostoma accompanied by anterior staphyloma. The tumor was excised by deep lamellar dissection, and the defect was filled with multilayer amniotic membranes. On histologic examination, the excised tumor contained demislike connective tissues, dermal adnexa (hair follicles and sebaceous gland), and adipose tissue, and was lined by keratinizing squamous epithelium. One month after surgery, the tumor recurred and progressively enlarged.
