These are warts, or papillomas, which is related to infection with equine papilloma virus.

Equine papillomatosis occurs most frequently in young horses and are most commonly found on the inner surfaces of the pinna, muzzle, distal limbs, and genitalia.

They are contagious, and since they usually resolve spontaneously, treatment is rarely pursued.

These differ from equine aural plaques, which are papillomas of the inner ear associated with fly bites that do not typically self-resolve.
