Multiple cutaneous inverted papillomas in a dog.
Cutaneous inverted papillomas are described in an 8-month-old mixed breed domestic dog from Windhoek, Namibia. Multiple firm, rapidly growing, doughnut-shaped masses formed on the ventral abdomen, which histologically consisted of a cup-shaped rim of marked epithelial hyperplasia, giant keratohyaline granules and prominent koilocytes and marked hyperkeratosis filling the centre of the mass. Current literature on canine papillomas is briefly reviewed.
