Multiple keratomas in an equine foot.

Summary

# Editorial Summary: Multiple Keratomas in an Equine Foot Keratomas—benign tumours of keratin-producing tissue within the hoof—are rarely encountered as multiple lesions, making this 2009 case report clinically valuable for equine practitioners. A 19-year-old Arabian gelding presented with hindlimb lameness and notable hoof wall deviation; radiographic examination identified a semicircular radiolucent defect at the lateral margin of the distal phalanx, prompting surgical intervention. Unexpectedly, three distinct keratomas were discovered and successfully removed following systematic hoof wall resection, revealing the potential for multiple concurrent lesions rather than a single mass. The radiographic appearance alone may underestimate the true extent of keratomatous disease, suggesting that clinicians should maintain vigilance for multiplicity when imaging raises suspicion, and that thorough intraoperative exploration remains essential. For farriers and veterinarians managing chronic unilateral lameness with progressive hoof wall deviation unresponsive to routine remedial shoeing, this case underscores the importance of radiographic investigation and early surgical referral, particularly in older animals where degenerative processes might otherwise be assumed responsible for clinical signs.
