Sarcoid in the horse: recognize, understand and treat naturally

The sarcoid is the most common skin tumor in horses, accounting for nearly 20% of the tumours observed in equine species. Generally benign, it does not endanger the life of the animal, but it can re-offend and become more aggressive if it is poorly managed. In this guide, we help you identify different types of sarcoid, to understand their causes, and to discover the natural solutions ESC Laboratory to accompany your horse, complement or alternative to veterinary treatments.

What is a sarcoid in the horse?

The sarcoid is a benign skin tumor that affects the horse: it does not metastase, unlike cancer, but it is locally aggressive and tends to recur. It comes from cells called fibroblasts, normally involved in healing, which explains why treatments that stimulate scar tissue can worsen the lesion.

It is often confused with a simple wart: unlike the papilloma, which disappears spontaneously in a few months in the young horse, the sarcoid almost never recedes alone and can infiltrate into the surrounding tissues. A viral factor, bovine papillomavirus, is now recognized as a probable trigger in horses Genetically predisposed.

The 6 types of sarcoid: how to recognize them?

There is Six forms of sarcoid in the horse, differentiated by their appearance and location. They can appear alone or in clusters, and the same horse can develop several types simultaneously.

Occult sarcoid

Flat and depilated area, covered with a grey and scaly crust, often circular. Frequently confused with moth. It is found mainly on the head, neck and between the hind legs.

Verruqueous sarcoid

Grey and scaly warts with more irregular contours than the occult type, often with several lesions around the affected area. It can evolve to an occult sarcoid.

Nodular sarcoid

Small bumps under thin and shiny skin, which can exceed 5 cm in diameter. Typical location: ain and eyelids.

Fibroblast sarcoid

Mass fleshy and aggressive, sometimes pedunculated, which can develop rapidly after a skin wound. Often ulcerated and very invasive for the surrounding skin.

Flat sarcoid

Discreet injury, skin simply a little thickened, often discovered late because it goes unnoticed during dressing.

Malignant sarcoid

The rarest and most aggressive form: it spreads through the skin and along the lymphatic vessels, with cords of tumour tissue interspersed with nodules and ulcerous lesions. The tumour is then larger and can cause real discomfort or even pain. Veterinary monitoring is essential.

Causes and risk factors of the sarcoid

The horse sarcoid usually develops at the location of an old insect wound, scar or sting, especially in areas of fine skin. Two main factors are now identified: papillomavirus bovine, transmitted by direct contact with cattle or indirectly via an already carrying horse or an insect bite, and genetic predisposition. Some breeds seem more sensitive, including the Quarter Horses, Appaloosas and Arab horses.

Is the sarcoid contagious?

The sarcoid is not contagious in the strict sense of the term. However, the sarcoid may be transmissible if the horse is carrying the predisposition gene: the bovine papillomavirus, carried by contact with cattle, with a horse already affected, or by picker insects acting as vectors, can then trigger the tumour. A healthy horse, without this genetic predisposition, will not develop a sarcoid simply in contact with an affected animal.

When do you need to consult a veterinarian for a sarcoid?

A stable, small, non-inconvenient sarcoid can be simply monitored. On the other hand, veterinary consultation is required if you see any of the following signs:

• rapid or sudden mass growth,
• ulceration,
• bleeding,
• or location in a sensitive area (eye, sheath, strap passage, or zone of friction of the harness).

The veterinarian can confirm the diagnosis by puncture or biopsy and determine the type of sarcoid in the presence. Remember that early treatment is always more effective than late intervention on an already large tumour.

Conventional sarcoid treatments in horses

There is no miracle cure for the sarcoid, and the risk of recurrence remains high regardless of the method chosen. The most suitable treatment depends on the position, size and number of tumours.

• Surgical discharge: performed under local or general anesthesia, it must be large to remove as many tumour cells as possible, but failure rate remains high and healing sometimes difficult.
• Ligature: a tight band is placed at the base of the tumor; It is possible only on a pedunculated sarcoid and can be painful.
• Cryotherapy: the tumor is frozen and then destroyed, at the cost of long, repeated treatment, often under general anaesthesia.
• Immunotherapy: injection of substances stimulating the immune system, effective especially near the eye, but requiring several sedation sessions.
• Radiotherapy: efficient but expensive treatment, reserved for a few specialized centres due to its technical complexity.
• Laser removal: a surgical laser removes the tumor and a healthy tissue margin to limit the risk of recurrence.

Natural Sarcoid Treatment: Internal and External Approach

Since these conventional treatments are often expensive and invasive, many owners turn to natural management, especially when the sarcoid is taken at an early stage.

Based on our field experience at ESC Laboratoire, equine herbal therapy gives the best results when it combines local topical action and internal immune support, in parallel with or without veterinary treatment.

Natural Topical Care: Sarcopurs and Tincture of Thuya

In local application, our care SARCOPUR, our care based on he combines essential oils selected to dry and remove sarcoids from equine epidermis. The tincture mother of thuya is a popular alternative when the horse is too sensitive to pure essential oils: the maceration process of the plant gives it a high level of plant actives with antiviral and keratolytic properties, traditionally used against warts and skin conditions such as fungus or psoriasis. In practice, dyeing applies daily using a compress directly on the lesion until visible disappearance.

Supporting horse immunity: the internal shutter

The role of herbal therapy is not limited to local action: it also aims at stimulate horse immunity pour l’aider à lutter contre les cellules tumorales. Plusieurs plantes sont traditionnellement utilisées en complément :

• L’ail (Allium sativum) : à raison de 15 à 20 g par jour dans la ration, pour son allicine et son effet préventif reconnu sur la promotion cellulaire anormale. Attention : l’ail réduit la coagulation sanguine et doit être arrêté plusieurs jours avant toute chirurgie.
• Le thym (Thymus vulgaris) : en infusion à raison de 50 g dans 1 à 2 litres d’eau, matin et soir, pour son action antioxydante et son rôle immunostimulant.
• L’échinacée (Echinacea angustifolia) : traditionnellement utilisée pour soutenir et stimuler les défenses immunitaires du cheval.
• Sarcomix, mélange de plantes : notre synergie spécifique conçue pour accompagner le cheval sur toute la durée du traitement, en cures de 3 semaines à 3 mois selon les cas.
• Fortimix : mélange de 9 plantes (algues marines, bardane, chardon-marie, chicorée, cynorrhodon, échinacée, gaillet-gratteron, ginkgo biloba, ortie) qui contribue au développement des défenses immunitaires et au drainage de l’organisme.

Comment combiner les deux approches : protocole type par ESC Laboratoire

Le protocole le plus efficace associe l’application quotidienne d’un soin topique (Sarcopurs ou teinture de thuya) à une cure interne de plantes immunostimulantes (Sarcomix, Fortimix, ou plantes pures) sur une durée de 3 semaines à 3 mois selon la taille et l’évolution de la tumeur.

Quelle que soit l’option choisie, il est essentiel de poursuivre le traitement jusqu’à l’obtention d’un résultat visible : un arrêt prématuré expose à un fort risque de récidive, parfois avec une lésion plus grave que la précédente.

Prévenir l’apparition ou la récidive du sarcoïde

Pour limiter le risque de sarcoïde, protégez et surveillez les plaies et cicatrices, terrain propice à l’installation du papillomavirus bovin. Un bon contrôle des insectes piqueurs, vecteurs potentiels de la maladie, réduit également le risque de transmission.

Enfin, un renforcement régulier de l’immunité de votre cheval, via une cure de plantes en préventif, peut aider à limiter les récidives chez les chevaux déjà touchés ou génétiquement prédisposés. Une surveillance régulière de toute masse cutanée reste le meilleur réflexe : si elle ne grossit pas, elle n’est en général pas inquiétante ; dès qu’elle évolue, direction le vétérinaire.
