Considered benign proliferations of skin epithelium, these lesions are benign, non-invasive, and do not metastasize. Dogs with generalized lesions have a strong tendency to develop new tumors at other sites. The generalized form is believed to have a hereditary basis in dogs.

Small Animal Dermatology Q&A 01.jpg



A 5-year-old male Norwegian elkhound dog with generalized confluent dermal masses is shown. The tumors are firm to fluctuant, well-circumscribed, dermal to subcutaneous masses varying in size from 0.5–>5.0 cm. Some of the lesions have visible pores opening onto the surface of the skin; the pores are filled with cutaneous plugs. The dog is otherwise healthy.
