This 10-year-old boy presented with a white spot on the left eye.  Vision is OD 20/20 and OS 20/20.  The spot has not changed in appearance since it was first noticed when the child was an infant.

1.	The most likely diagnosis is:
	c -- dermoid This is the typical appearance and location of a limbal dermoid.  The mass is comprised of ectopic rests of tissue with normal cell structure but occurring in an abnormal location.  These are called choristomas.
2.	Treatment for this condition is:
	b -- surgical excision of the raised portion Treatment, if elected, is surgical excision of the raised portion of the dermoid.  Since the dermoid extends into the substance of the cornea a whitish discoloration of the cornea usually persists.  This is usually less noticeable than the raised mass. Patients should be informed before undergoing surgery that the eye will look better, but the condition not eliminated.
3.	This condition can be associated with which of the following?
	d -- Goldenhar’s syndrome Limbal dermoids are seen in Goldenhar’s syndrome which is also known as oculoauriculovertibral dysplasia.
