Dermoid is a choristoma, which is a congenital mass of tissue that appears in an abnormal, unnatural location (Gelatt, 1991). In eye, dermoid appears as a skin or skinlike appendage on the cornea and conjunctiva, extending from the limbus (Archibald, 1974). It appears in dogs usually on the temporal aspect of the cornea, but has been observed involving different proportions of the anterior segment surface. It can be unilateral or bilateral and may be associated with other ocular malformations. It can occur in any breed, but occur most frequently in Saint Bernards, Dachshunds and Dalmatians (Gelatt, 1981). Being a congenital anomaly, its pathogenesis has not been clearly known (Jubb et al., 1993).
