A Lump Below the Cheek on a Horse's Face

When a lump is found on a horse's head or neck area, a complete physical examination of the horse is necessary. The health history and present demeanor of the horse also are important.

  1. Sarcoids

    • Sarcoids are the most common diagnosed tumors in horses. Although they are more common in younger horses, they can occur at any age. Sarcoids are diagnosed through microscopic examination. Sarcoids are treatable but tend to return after removal.

    Strangles

    • Lymph glands under the jaw of the horse will swell and fill with pus when the horse suffers from strangles. Strangles is a highly contagious bacterial infection among horses. In some cases, the abscesses that form under the jaw must be opened and drained.

    Infection and Other Symptoms

    • Viral, bacterial and fungal infections in the head area may cause the lymph nodes under the horse's cheek to swell. Other problems that cause the head and jaw area to swell include impacted or abscessed teeth, blunt trauma, allergic reactions, balling of feed and even developmental abnormalities.

    Veterinary Care

    • Always seek veterinary care when health issues arise. Never try to diagnose a potential health problem without veterinary assistance.
