Equine sarcoids are the most common skin tumor in horses and require individualized management decisions based on location, size, and progression.
Sarcoids in welfare-sensitive locations cause pain, restrict equipment use, and can become aggressive following trauma. Eye margin sarcoids in particular can threaten vision. The welfare approach is location-specific: small, stable sarcoids in non-critical locations may be monitored rather than treated. Active management is warranted for growing sarcoids, those at girth or eye margin, and those restricting normal function. Treatment selection should balance efficacy against treatment-related side effects.
