Can Horses Get Sarcoidosis?

Equine sarcoidosis seems to be an emerging problem. As more horses are referred for dermatologic disease, equine sarcoidosis should be considered in any case of exfoliative and/or nodular skin disease with or without systemic involvement, including generalized granulomatous disease affecting most internal organs.

How do I know if my horse has sarcoidosis?

Recognising sarcoids in horses
Some sarcoids look like smooth, nodular skin lumps, especially in the early stages, while others are irregular and roughened from the start. The lumps frequently become larger, irregular in shape and cauliflower-like in appearance.

What is equine sarcoidosis?

Sarcoids are the most common skin tumour of horses, accounting for 40% of all equine cancers. They affect breeds of all ages and both sexes. Most skin lumps in horses that are non-painful and non-itchy are sarcoids, whereas painful lumps are often due to infection and itchy lumps to allergies.

Can sarcoidosis be cured in horses?

Sarcoids, the most common skin tumor of horses, are believed to be caused by the bovine papilloma virus. They can be treated with chemotherapy drugs, such as cisplatin, or removed surgically or with lasers. However, Espy says, if any trace of a growth remains, the sarcoids will return.

Can sarcoidosis be passed from horse to horse?

Some horses are genetically predisposed to developing sarcoids. There is currently no evidence that sarcoids can be transmitted from one horse to another, however if a horse is predisposed to sarcoids then having one sarcoid will increase the risk of another sarcoid developing on the affected horse.

What age do horses develop sarcoids?

Certain breeds are more likely to develop sarcoids than others with thoroughbred’s accounting for a large number of the horses affected. The vast majority of cases arise between the ages of 3 and 6 years of age although growth in later years does occur.

Are all sarcoids on horses cancerous?

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.

What does sarcoid look like?

A rash of red or reddish-purple bumps, usually located on the shins or ankles, which may be warm and tender to the touch. Disfiguring sores (lesions) on the nose, cheeks and ears. Areas of skin that are darker or lighter in color. Growths under the skin (nodules), particularly around scars or tattoos.

What is the survival rate of sarcoidosis?

Overall, the disease mortality is about 5 percent. Those cases which warrant additional concerns are those involving the heart and those that cause severe scarring in the lungs, which can cause respiratory failure.

What do sarcoid granulomas look like?

Smooth bumps or growths
Mostly painless, these bumps and growths tend to develop on the face or neck, and often appear around the eyes. You may see lesions that are skin-colored, red, reddish-brown, violet, or another color.

Is sarcoid fatal?

When the granulomas or fibrosis seriously affect the function of a vital organ — such as the lungs, heart, nervous system, liver, or kidneys — sarcoidosis can be fatal. Death occurs in 1% to 6% of all patients with sarcoidosis and in 5% to 10% of patients with chronic progressive disease.

What is end stage sarcoidosis?

End-stage sarcoidosis is typically characterised by severe interstitial fibrosis occurring along the bronchovascular bundles with cystic changes 1, 2. Chronic interstitial pneumonitis typically occurs in the early stages of sarcoidosis and is localised to the areas affected by granulomas 3–5.

Does toothpaste work on sarcoids?

Approximately 10% of horses recover from sarcoids naturally — which is what Prof Knottenbelt believes may have led people to believe that the toothpaste treatment works. He warns that not only does the remedy not work, but it is also dangerous because it delays treatment and can irritate the tumour.

Will a horse pass a vetting with sarcoids?

In general, any sarcoid near an area of tack would be a cause to fail a vetting, as would a sarcoid near the eyes or muzzle (these can be notoriously difficult to treat).

What disease is transmissible from horses to humans?

Salmonellosis (Salmonella spp.) Salmonellosis is a disease caused by Salmonella bacteria, which are most commonly spread through contaminated food. Salmonella can also spread from animals, including horses, to people and between people.

How is sarcoidosis transmitted?

Sarcoidosis can occasionally occur in more than one family member, but there’s no evidence that the condition is inherited. The condition is not infectious, so it cannot be passed from person to person.

What is the difference between sarcoid and sarcoidosis?

Sarcoidosis, also called sarcoid, is a condition where inflamed cells join together to make tiny lumps called granulomas. This can happen in any part of your body. They are most often found in the lungs and the lymph nodes (glands).

What percentage of horses get sarcoids?

Affecting between 2-8% of horses, it is a common disease. Sarcoids can occur almost anywhere on the skin, although there are some regions that are more liable to their development.

What do early sarcoids look like?

Occult sarcoids appear as roughly circular hairless areas of skin (Fig. 1). They often are quite subtle early in their development and sometimes difficult to recognise. They can occasionally be mistaken for ‘ring-worm’ or even rub marks from tack.

Can sarcoids go away on their own?

They can appear in a variety of different forms (from flat / warty areas of skin to lumps) and are usually persistent and progressive. Very occasionally, in young horses, sarcoids can spontaneously disappear, but this is rare.

Do flies spread sarcoids?

It is believed that sarcoids are caused by a virus spread between horses by flies which takes advantage of small wounds in your horse’s skin. They are seen most commonly around eyes, ears, chest, the belly and the lower limbs. Some horses may only have one sarcoid whilst others may have several across their body.
