Ceruminous Gland Tumors in dogs

These tumors arise from wax-producing glands in the ear canal. They are pinkish-white dome-shaped growths, less than 1 centimeter across. Most are pedunculated (on a stalk), with the base attached to the wall of the ear canal. The length of the stalk allows the tumor to extend outward and become visible. Ceruminous gland tumors may become infected and bleed.

Small tumors tend to be benign. Large tumors are usually malignant and invasive. Cocker Spaniels seem to be predisposed to these tumors.

Treatment: Surgical removal is the treatment of choice. Surgery, combined with radiation therapy, is recommended for invasive tumors.
