Surgical correction of a corneal-conjunctival dermoid cyst in a dog (canis lupus familiars). Clinical case

“…This is consistent with our clinical case, where we had no post-operative problems and the resolution was satisfactory. 2,5,8,13 Although its presentation is generally unilateral, in dogs in several works cases of dermoids have been described mainly in the right eye. In our clinical case it was in the left eyewhich agrees with the case of a labrador.…”

“…4 These choristomas can appear in different structures of the animal eye including that of man; such as the bulbar conjunctiva, cornea, palpebral conjunctiva, nictitating membrane. [3][4][5] Although bilateral dermoids have been described both in man and in domestic animals, their presentation is generally unilateral. In dogs, in several studies cases of dermoids have been described mainly in the right eye.…”

“…In dogs, in several studies cases of dermoids have been described mainly in the right eye. 2,5,6,7 The formation of these choristomas occurs during embryonic development through defective tissue differentiation. The pathophysiology of the dermoids is still unknown.…”

“…Dog breeds such as the German Shepherd, Danchshunds, Golden Retrivers; in cattle, the Herefords breed seems to have a genetic predisposition. 2,5,8 So far there is no classification of dermoids in dogs, but in humans there is a classification made by Ida Mann: the first type is limbic, it is the most frequent, the second type is the one that affects the cornea and can affect part of the stroma without affect Descemet's membrane and corneal endothelium, and the third type affects the entire anterior segment. 6,8,9 The objective of this article was to present a clinical case of a dermoid cyst with localization lateral corneo-conjunctival between the limbus of the cornea and the sclera of the left eye (LE), that was featured in an American Bully dog and its resolution it was by surgical removal of the dermoid and its subsequent satisfactory post-surgical follow-up.…”

“…α2-agonists, including xylazine, medetomidine and dexmedetomidine, are the most widely used sedatives in veterinary medicine [3,21,[48][49][50][51] . These drugs are also administered during general anaesthesia to improve analgesia and to decrease the dose of the anaesthetics used.…”
