Facts About Equine Sarcoids That You Need To Know



What is a Sarcoid? 


A sarcoid is a skin tumour that is caused by the virus bovine papillomavirus (BPV).

They are locally invasive tumours that are a type of skin cancer in horses.  Sarcoids do not spread to any other organs and don't effect the horse's health.  The only problem is that a horse with the virus will spread it to other horses.  They can also spread to other places on the body even if the horse as gone through a successful removal.

Once a horse has the virus it will either develop sarcoids or it will not develop any but it is still able to spread the virus on to other horses.

The virus is either spread from horse to horse (touching) or spread from flies that feed on an infected horse.



Types of sarcoids


1.  Verrucose - A flat tumour.  These are the least aggressive type and look like a scar or ringworm.

2.  Nodular - Lumps that are covered by skin or look like a large ulcer.  They grow are a medium rate.

3.  Fibroblastic - These are aggressive and grow quickly,  The look like ulcers but can also grow in the tissue under the skin.  They grow in clusters.

4.  Malignant - They spread through lymph vessels nearby which means a group of malignant sarcoids grow in a line.

5.  Mixed - Some horses may develop a few different types of sarcoids.



Treatment 


Removal treatment includes freezing therapy, laser treatment, surgical removal, topical chemotherapy, injection of chemotherapy into the tumour, radio wave therapy, heat treatment and more.

Most vets will not remove or give any treatment unless the tumour is very aggressive or it is hurting the horse.

Removing the tumour does not mean removing the virus.  Sarcoid can grow back after removal or grow in different places.  Even if they don't grow back they still have the virus and will still spread the virus to others through flies.
