X-linked corneal dermoid (X-CND) is an exceedingly rare, benign, congenital, corneal tumor characterized by bilateral opacification of the cornea with superficial grayish layers and irregular raised whitish plaques, as well as fine blood vessels covering the central cornea, and intact peripheral corneal borders. No other ocular or systemic abnormality is noted. The pattern of inheritance described in the affected family is consistent with X-linked transmission.	Associated morphology	False	Dermoid choristoma	Inferred relationship	Some	2
Ring dermoid of cornea is characterized by annular limbal dermoids (growths with a skin-like structure) with corneal and conjunctival extension. Less than 30 cases have been described. Transmission is autosomal dominant and mutations in the PITX2 gene have been suggested as a potential cause of the condition.
