Central corneal dermoid in a Labrador retriever puppy

Abstract

An eight-week-old, male Labrador retriever puppy was presented with an abnormal appearance of the left cornea, observed after the eyelids opened in the second week of life. Ocular examination showed a large central dermoid of the left cornea. The dermoid was excised by superficial keratectomy, and healing was uneventful. The dermoid was classified as a Mann's second type. To the authors' knowledge, a Mann's second type corneal dermoid has not previously been reported in a dog.

Conjunctival Dermoid in A Belgian Malinois Dog

“…Dermoids may be existed in the eyelids, conjunctiva (palpebral or bulbar) and nictitating membrane, unlike cornea is commonly affected [1] . Dermoids usually localize at the temporal limbal area and extend to the sclera and cornea [7] . In our case, the dermoid was originated from conjunctiva and localized at KORKMAZ, YAVUZ DEMIREL, DEMIRKAN the temporal limbal area as previously described above [7] .…”

“…It has been postulated that most dermoids seen in dogs are corneal dermoids [7][8][9][10] . Erdikmen et al [9] reported that 16 of 22 dogs with dermoids presented corneal dermoids.…”

“…Our aforementioned findings suggest that ulcerative keratitis may not be observed in all cases of conjunctival dermoid in dogs. Histopathologically, the dermoids contain many of the elements of normal skin such as epidermis, dermis, fat, sebaceous glands, hair follicles and adipose tissue [2,7,9] . Similarly, in our case, sebaceous gland, sweat gland and blood vessels were observed in the microscopical examination of the resected tissue.…”

“…Ocular dermoid contains many of the structures of normal skin such as epidermis, dermis, fat, sebaceous glands or hair follicles [5,6] . Ocular dermoid has been reported in several domestic animals such as dogs [6][7][8][9][10] , cats [11] , horses [12] , sheep [13] , cattle [14] , rabbit [15,16] , Guinea pigs [4] , and birds [17] .…”
