Canine papillomavirus type 16 associated to squamous cell carcinoma in a dog: virological and pathological findings.

ABSTRACT: Papillomaviruses (PVs) are circular double-stranded DNA virus belonging to Papillomaviridae family. During the infection cycle, PVs translate proteins that can influence cell growth and differentiation, leading to epidermal hyperplasia and papillomas (warts) or malignant neoplasms. Canis familiaris papillomaviruses (CPVs) have been associated with different lesions, such as oral and cutaneous papillomatosis, pigmented plaques, and squamous cell carcinomas (SCCs). Here, we report a clinical case of a mixed bred female dog with pigmented plaques induced by CPV16 (Chipapillomavirus 2) that progressed to in situ and invasive SCCs. Gross and histological findings were characterized, and the lesions were mainly observed in ventral abdominal region and medial face of the limbs. In situ hybridizat
