Understanding and Treating Sarcoids in Horses
Sarcoids in horses are a common type of tumor, affecting both their health and performance. While that may sound alarming, sarcoids are not malignant. However, they can be persistent, recurring, and often uncomfortable for your horse. Early detection, timely veterinary care, and supportive measures, including immune support, anti-inflammatory care, and skin-repair supplements, are crucial for effective management and recovery.
In this blog, we’ll explain what sarcoids are, their causes and risk factors, the symptoms to monitor, and the available treatment options. We’ll also explore how proper nutrition and targeted supplements can support your horse’s recovery and overall well-being.
What is a Sarcoid?
Sarcoids are non-malignant skin tumors in horses, affecting 1% to 11.5% of animals. They can appear anywhere but are most common around the head, neck, lips, eyelids, ears, extremities, and abdomen. While horses of all ages can develop sarcoids, they are most frequently seen in younger and middle-aged animals.
These tumors can be persistent or recurrent because the bovine papillomavirus (BPV) that causes them may remain in the skin cells. Factors like a weaker immune response, incomplete removal, repeated trauma, or genetic susceptibility increase the risk of regrowth even after treatment.
Causes and Risk Factors
These are the causes and risk factors that contribute to the development of sarcoid tumors:
- Viral Etiology: The development of sarcoid tumors in horses is closely linked to the infection with bovine papillomavirus (BPV), which is transmitted through insects like flies or contact with contaminated equipment.
- Genetics: In the United States, sarcoids are more common in Quarter Horses, Apaloosas, and Arabians as compared to Standardbreds, indicating that some horses may be genetically predisposed to developing sarcoids.
- Environmental Factors: Flies, insect bites, open wounds, or areas of chronic irritation may act as entry points or aggravating factors for sarcoid growth.
- Immunity: Horses with compromised or weakened immune systems are more prone to developing sarcoid tumors.
Types of Sarcoids
There are six main types of sarcoids in horses:
|
TYPE |
DESCRIPTION |
|
Occult |
These appear as small, flat, hairless patches that are slow-growing and often go unnoticed in the initial stages. |
|
Verrucous |
Rough, warty growths with a raised appearance. |
|
Nodular |
Small, raised, and firm bumps are found under the skin. They are freely movable and can sometimes have an ulcerated skin. |
|
Fibroblastic |
Ulcerated, locally aggressive, and fleshy masses that may present with bleeding. |
|
Mixed |
These have characteristics of one or more subtypes. |
|
Malevolent |
The most highly recurrent and aggressive form, these tumors infiltrate along vessels and fascial planes, and can spread rapidly. |
Symptoms and Diagnosis
Recognizing the symptoms of sarcoids in horses and getting a diagnosis are key to effective treatment.
Common Symptoms:
- Hair loss or bald patches of skin.
- Visible lumps or warts.
- Ulceration and bleeding.
- Horses may develop irritation, sensitivity, or compulsive rubbing at the affected site.
Diagnosis:
If you suspect your horse has sarcoids, a veterinary examination should be your next step. Your vet will examine the lesions and consider biopsy and imaging to determine the exact type and rule out other skin lesions or tumors. Early detection leads to improved outcomes of sarcoid treatment in horses.
Treatment Options
Equine sarcoid treatment can be challenging because of the persistent nature of the tumors.
- Conventional treatments for sarcoids include surgical removal, cryotherapy (freezing), laser therapy, immunotherapy, and topical applications. Large tumors may require a combination of approaches.
- Sarcoid tumors tend to recur and can heal slowly, particularly in areas subject to movement or trauma.
Because each case is unique, the best treatment for your horse should always be determined under veterinary guidance.
How Supplements help Support Recovery
While no supplements replace veterinary treatment, the right nutritional support can complement recovery and help your horse recover comfortably.
- Nutritional supplements that support the immune system, like Vitamins E, Zinc, and Selenium, may help the horse’s body respond better to sarcoid treatment.
- Certain supplements rich in targeted minerals, antioxidants, and vitamins can also help in tissue and skin repair.
- A well-rounded feed plan that includes specialized equine energy supplements can also help support recovery.
Prevention and Management Tips
These are some prevention and management tips for sarcoids in horses:
- Implement fly control and minimize exposure using repellents, masks, and clean stabling to reduce BPV transmission and irritation.
- Treat wounds promptly to prevent infection.
- Support overall health with balanced nutrition, regular exercise, and preventive supplements for immunity.
- Groom and clean your horse regularly to detect skin lesions or changes early.
- Avoid trauma or constant rubbing of sarcoid-affected areas to prevent worsening or spread.

FAQs
Q1. Can sarcoids in horses heal on their own?
Ans. Sarcoids very rarely heal on their own without treatment. Most require veterinary intervention to prevent them from getting worse.
Q2. Are certain horse breeds more prone to sarcoids?
Ans. Yes, horses like Quarter Horses, Arabian Horses, and Appaloosas are more prone to sarcoids due to genetic factors, but sarcoids can affect any horse regardless of the breed.
Q3. How quickly should a horse with suspected sarcoids see a vet?
Ans. If you suspect your horse has sarcoids, get a diagnosis from a vet as soon as possible. Early diagnosis and treatment usually have better outcomes.
Q4. Which supplements are most effective for supporting skin and immune health?
Ans. Some of the supplements that can support skin and immune health are Vitamin E, Zinc, Selenium, and Omega-3 fatty acids.
Q5. Can sarcoids affect a horse’s performance or comfort?
Ans. Yes, it depends on the tumor’s size and location. Sarcoids can affect performance, tack fit, movement, and cause discomfort.
