Abstract

A 2-week-old calf in the USA was presented because of severe ocular irritation; examination revealed a large conjunctival dermoid. A conjunctivectomy was curative, as evidenced by no recurrence with a 4-month follow up. A review was compiled from the literature and the Veterinary Medical Database. Dermoids have been reported in 22 breeds of cattle, with the Hereford being overrepresented. Average age at presentation is 6.1 months. Calves usually show signs of severe ocular irritation, which is caused by hair on the surface of the dermoid. Dermoids may occur on the cornea, limbus or conjunctiva. Surgical excision via keratectomy or conjunctivectomy after sedation with xylazine and local anaesthesia is curative in most cases.
