Canine papillomatosis is mainly attributed to papillomavirus infections. Papillomavirus DNA is also frequently identified in healthy skin, and evidence of high papillomavirus diversity complicates this simplistic view of causality. The aim of this study was to determine how frequently canine ...

Background: Papillomavirus infections in dogs have a variety of manifestations and involve multiple viral genera. Canine pedal papillomas have been infrequently studied and reported in the literature. Objective To report the signalment, history, treatment and outcome of biopsy-confirmed cases of ...

A 1.5-year-old, male intact Basset Hound presented with a 2-month history of rapidly progressing oral papillomatosis. The dog exhibited ptyalism, oral pain, difficulty in prehending food and a strong malodor from the oral cavity. The dog was unresponsive to oral azithromycin and injectable...

CPV1 (also called COPV) is a papillomavirus responsible for oral papillomatosis in young dogs. The involvement of this viral type in oral oncogenesis has been hypothesized in oral squamous cell carcinomas (SCCs), but has never been investigated in other neoplastic and hyperplastic oral lesions of ...

This case report describes a rare case of a persistent canine papillomavirus type 1 (CPV-1)-induced oral papilloma that underwent malignant transformation into an oral squamous cell carcinoma (OSCC) in a 3-year-old Labrador retriever cross. Initially, the patient had multiple and multifocal...

Papillomas of the conjunctival surface in people can be of viral or nonviral origin and are found in high association with human papillomavirus. Canine conjunctival papillomas are seldom described, and published accounts have mostly been associated with canine oral papillomavirus infection. Here,...

Canine oral papilloma is a benign tumor of young dogs and caused by papillomavirus. The possible role of papillomavirus infection in the development of oral squamous cell carcinoma has recently been studied, but it has not been elucidated in veterinary medicine yet. A one-year-old, mixed, spayed,...

Recently, histologic subtypes of oral squamous cell carcinoma (SCC) corresponding to the human classification scheme have been proposed for dogs. A papillary squamous cell carcinoma subtype is characterized by dominant exophytic architectural growth with limited invasion, a lower metastatic rate,...

Canine cutaneous viral papillomas are caused by papillomavirus. Papillomatosis is considered to be a low-frequency disease in dogs and is characterized by the presence of single or multiple lesions in the oral cavity, subcutaneous tissue, or ocular region. The oral and facial exophytic forms are...

Papilloma is a commonly benign neoplasm of viral etiology, with a cauliflower appearance, often found in canine species. It can present in the cutaneous, oral or ocular form, the latter being less common among animals. Clinical diagnosis is commonly used through its common morphological...
