Clinical, dermoscopic and histopathological features of multiple cutaneous tumours ascribed to sun damage in a Chinese crested dog

This case report describes the clinical, dermoscopic and histopathological findings of three different neoplastic lesions (angiokeratoma, squamous cell carcinoma and multiple melanocytomas) and non‐tumoral skin in a hairless Chinese crested dog following chronic sun exposure. The non‐tumoral skin was characterized by “sunburn cells”, collagen degeneration, dermal elastosis and fibrosis, described in most species as caused by UV light exposure. Cutaneous angiokeratomas have been rarely reported in the canine literature. In this particular case we consider a possible correlation with UV damage.
