Pigmented viral plaque is most commonly seen in Pug dogs in association with canine papillomavirus (CPV). In the present study, nucleic acid sequence and localization of viral genes were examined in 4 cases of pigmented viral plaque in Pug dogs. The results of polymerase chain reaction and nucleic...

A pedunculated exophytic mass developed on the rump of a dog. Fine-needle aspiration revealed keratin debris suggestive of a follicular tumor. However, histology revealed a pigmented viral plaque that contained numerous keratin-filled cystic cavities. Canine papillomavirus 18 DNA sequences were...

Cutaneous pigmented viral plaques is a disorder of epidermal growth caused by canine papillomavirus type 4 (CPV-4). There is currently no standard of care for managing this condition and it has not been reported in the Hungarian Vizsla. This case series documents the clinical features of canine ...

A 6-year-old, intact, male pug was presented with black plaques without pruritus on the inner thigh during long-term administration of systemic prednisolone. The histological findings were compatible with viral pigmented plaque in dogs. PCR and DNA sequencing were performed using DNA extracted from ...

Papillomaviruses (PV) are associated with benign mucosal and cutaneous epithelial proliferations. In dogs, PV-associated pigmented plaques and papillomas can undergo malignant transformation, but this is rare, and most cases of canine squamous cell carcinoma do not arise from PV-induced precursor...

In dogs, papillomaviruses are thought to cause oral and cutaneous papillomas and pigmented plaques. Eight canine papillomaviruses have been fully sequenced to date. Four of these canine papillomaviruses, including Canis familiaris papillomavirus (CPV)-3, CPV-4, CPV-5, and CPV-8, were amplified from ...

Extensive exophytic pigmented viral plaques developed on a Chihuahua dog causing pruritus and discomfort. Neither the medical treatments used nor a papillomavirus vaccine resulted in clinical improvement. Laser surgery removed some plaques, yet others developed. This case illustrates the difficulty ...

Background: Canine pigmented viral plaque (PVP) is an uncommon skin disease, associated with papillomavirus infection. Lesions are usually small (<1 cm diameter), pigmented macules to plaques on the ventral abdomen and medial thigh. Animals: An 8-year-old male, neutered golden retriever dog presented with numerous...

Canine papillomaviruses (CPVs) have been identified in various benign and malignant neoplastic skin disorders. The most frequent manifestations of CPV infections are classical warts and pigmented plaques. Although the etiology of canine oral papillomatosis is well established, knowledge about CPVs...

Background: Seborrhoeic keratoses (SKs) are common benign epidermal neoplasms in humans and are rarely diagnosed in the dog. These circumscribed, raised, variably pigmented plaques arise in middle aged to older humans, with a focal or multicentric distribution; although common, the underlying cause ...
