Understanding Equine Sarcoids with Professor Derek Knottenbelt

Sarcoids are the most common skin tumors in horses, and yet they remain one of the most frustrating conditions for owners, riders, and veterinarians alike. In this episode of PKN Podcast, we’re joined by Professor Derek Knottenbelt, world-renowned equine medicine specialist and leading authority on sarcoids, to explore this complex disease in depth.

With more than four decades of clinical experience and research, Professor Knottenbelt has played a central role in shaping how the equine world understands, diagnoses, and treats sarcoids. He explains what sarcoids are, the different forms they can take, how they develop, and what makes them so persistent. We also discuss the latest approaches to treatment, what owners should (and shouldn’t) do when faced with a suspicious skin lesion, and how early intervention can make all the difference.

Whether you are a horse owner, equestrian professional, or veterinary student, this episode will give you practical insights, expert guidance, and a deeper understanding of how to support horses living with this condition.
