Case summaryAn 11-month-old female neutered Ragdoll cat was presented for focal seizures, aggression and altered behaviour. A diagnosis of a nasal dermoid cyst with intracranial extension was made following MRI, cytology and histopathology. The cyst was surgically excised with a resolution of clinical signs, with the exception of ongoing seizure activity requiring anti-seizure medication.Relevance and novel informationTo our knowledge, this is the first reported case of a nasal dermoid cyst in a cat, and the first reported case in the veterinary literature of any species with a nasal dermoid cyst presenting with neurological signs.

“…To the best of our knowledge, this is the first report of a case of different types of DS on the head in a Saint Bernard dog. In the veterinary literature, there are only two other studies that described true cutaneous dermoid cysts (DS type V) in dogs [11,26] and neither of them were of subtype b. Our case is also unusual for its presentation on the head, for the breed affected and the multiplicity of the lesions, a pattern rarely described in dogs or humans [6,14,16,19].…”

“…Isolated cases of DS have also been reported in other breeds (Table 1) [9-40], without evidence of a genetic predisposition [34,51]. Several authors have reported that DSes are found most frequently in the cervical and thoracic regions [11,14,38] with possible extension to the meninges and subarachnoid space [9,21,23,32,33,35-37,39,40]. They are less frequently found in the sacral region [38].…”

Multiple dermoid sinuses of type Vb and IIIb on the head of a Saint Bernard dog

et al. 2013

Dermoid sinus, a congenital malformation of neural tube development, has been reported in humans and several animal species including dogs. It is typically found in the dorsal midline and commonly occurs in the Rhodesian Ridgeback breed. A case of multiple dermoid sinuses in the fronto-occipital region is described. An 11-month-old, intact female Saint Bernard dog was presented with a 2 day history of discharge from a large irregular subcutaneous mass in the fronto-occipital region. The dog was otherwise healthy. The dog had two circular skin lesions (approximately 4 × 4 and 4 × 2 cm diameter) surrounded by multiple irregular elevated masses. The masses had multiple small openings on the skin surface with tufts of hair protruding from the apertures. The masses were surgically removed, and the diagnosis of multiple dermoid sinuses was confirmed by histological examination. Histopathological examination showed multiple, variably sized, spherical to tubular cysts expanding the dermis and subcutis. Cysts were filled with hair shafts and lamellar keratin and were lined by a stratified squamous epithelium. Sebaceous and apocrine gland adnexal structures were also observed. To the best of our knowledge, this is the first reported case of multiple dermoid sinuses of two different types in the head of a Saint Bernard dog.

“…These dermoid sinuses most commonly occur along the spinal region, but have been reported to affect the nose in spaniels and a variety of other breeds. [1][2][3][4] Some dogs can have multiple dermoid sinuses. 5 In children it is known that the embryonic derivation of nasal dermoid sinus cyst is unique compared with that of dorsal midline dermoid sinuses, with incomplete obliteration of the neuroectodermal tissue in the prenasal space.…”

Intranasal dermoid cyst without external sinus tract or swelling in an adult cocker spaniel

An adult female cocker spaniel presented with acute-onset sneezing. Advanced imaging of the nasal cavity revealed a mass lesion with erosion of the normal bony structures. Cytology and histopathology revealed intralesional keratin and marked inflammation. This was suggestive of a nasal dermoid cyst despite the lack of external swelling over the nose and absence of a draining sinus tract. The cyst was successfully removed surgically via rhinotomy. Some crusting was seen at the nostril postoperatively, which was considered secondary to reduced lacrimal secretion. No other signs persisted and the dog made an excellent clinical recovery. This is the first report of an intranasal dermoid cyst in a dog with no external signs of swelling or sinus tract.
