By Garrett Metcalf, DVM

Sarcoids are the most common cutaneous skin tumor of horses that come in various forms with varying degrees of virulence. Sarcoids are small gray to cherry red tissue that appears similar to granulation tissue or proud flesh that does not seem painful and do not spontaneously regress.

These masses range from a very flat hairless area to very large raised aggressive forms. There are actually six forms or classifications of sarcoids in horses based on the appearance and behavior the mass exhibits. Sarcoids can appear around the face, eyes, ears, lower limbs, neck, groin and areas of previous injury or wounding.
