Horses + Tumors

  • A keratoma is a rare benign tumor of the inner layer of keratin-producing epidermal hoof wall cells that forms inside a horse‚Äôs foot. As the tumor slowly grows, it expands and separates the hoof wall laminae, causing pain and lameness.

  • Equine sarcoids are the most common tumors seen and account for approximately nine out of every ten skin tumors seen in horses. They are non-malignant (i.e., they do not spread throughout the body) but do grow larger and often spread and multiply locally.
