Abstract

Actinic keratosis is a skin disease that affects dogs, mainly short-coated and white-haired skin ones. The main cause is cronically sun exposure, which leads to local and sistemically imunologic changes. The article shows 10 dogs with actinic keratosis. Breed, sex, age, lesion site and aspect were evaluated. Skin biopsies were performed in all dogs, using a 6mm punch to establish the definitive diagnosis. The majority were female, American Pit Bull breed, with mean age of 4,3 (0,8) years old. Crusts, scales, alopecia and papules were seen in ventral abdomen, flank, and medial thighs. Secondary infection was a common finding. Epidermal hyperplasia and dysplasia were seen, without basal membrane involvement.
