An eight year old quarterhorse gelding used mostly for weekend pleasure riding was presented to the New York State College of Veterinary Medicine with chief complaints of intermittent left forelimb lameness, a deformity in the hoof wall of the left fore and a swelling at the coronet of the left fore. The left forelimb lameness and hoof wall deformity were first detected by the owner 1.5 years ago. Examination by a local veterinarian which included radiographs failed to determine the cause of the lameness and hoof wall deformity. Approximately two months prior to presentation the owner detected a swelling at the coronet just proximal to the hoof wall deformity. This swelling seemed to rapidly increase in size during the two month period prior to presentation. Lameness examination and radiographic examination at the New York State College of Veterinary Medicine lead to the presumptive diagnosis of mass lesion in the left front foot. The mass was removed via partial hoof wall resection. A definitive diagnosis of keratoma was made based upon the results of histopathological examination. The clinical aspects of keratomas including diagnosis, surgical removal and aftercare will be discussed.
