Abstract
Studying the naturally occurring skin cancers seen in companion (pet) animals provides an opportunity to improve our knowledge about the biology, epidemiology, pathogenesis, and treatment of skin cancer across species, contributing to advances in human and animal health through a comparative oncology approach. A comparative oncology approach to the study of skin cancer integrates knowledge and studies of these naturally occurring cancers in pets with other basic and clinical research. Studying the similarities and the differences between neoplastic conditions of animals and humans can provide additional knowledge and insight into the biology of cancer. This chapter reviews the clinical features, pathology, and molecular biology associated with the common skin cancers seen in animals, focusing on the similarities and differences between animals and humans.

Glossary
- Basal cell tumors (adenoma and carcinoma)
-
Tumors originating from skin basal cells, characterized by local invasiveness and almost lack of metastatic potential
- Companion animals
-
house pets (dogs and cats)
- Cox-2 cyclooxygenase type 2
-
Is a enzyme that is frequently overexpressed in pet tumors; it increases angiogenesis, tumor cell proliferation and resistance to apoptosis. It is frequently targeted in veterinary oncology using cox-inhibitors
- Melanoma
-
A melanocitic tumor localized in the skin or muco-cutaneous regions. The cutaneous localization is associated with aggressive behavior in 10% of the horses while it is benign in pets. The mucocutaneous location is associated with local invasiveness and distant metastases in pets
- p53
-
A tumor suppressor genes frequently mutated in tumors of companion animals
- Sarcoid
-
An equine neoplasm caused by non productive papillomavirus infection
- Squamous cell carcinoma
-
a rapidly growing, usually sun-induced tumor of skin and nasal planum, more common among pets with depigmented areas of the body
- VEGF
-
Vascular endothelial growth factor is a growth factor and promoter of angiogenesis that is frequently overexpressed in canine cancer (squamous cell carcinoma and melanoma) and is sometimes associated with patient outcome
