Plain-English summary
A 13-year-old French saddle gelding horse had a skin problem on its lower legs that lasted for six weeks. After examining skin samples, the veterinarians found that the horse had a rare condition called pastern vasculitis, which involves inflammation of small blood vessels in the skin. They discovered that a tough-to-treat bacteria called multidrug-resistant Pseudomonas aeruginosa was causing the issue. The horse was treated with a six-week course of a medication called enrofloxacin, and after treatment, the horse showed improvement and did not have any further skin problems. Overall, the treatment was successful.
Abstract
BACKGROUND: Equine pastern vasculitis is an uncommon disorder in horses. Underlying causes are difficult to assess, especially bacterial infections. CLINICAL SUMMARY: A 13-year-old French saddle gelding horse presented for evaluation of a six weeks history of pastern dermatitis. Histopathological examination of skin biopsy samples revealed small vessel vasculitis. A pure growth of a multidrug-resistant Pseudomonas aeruginosa (MRPA) was obtained from a deep skin biopsy. Clinical remission was observed after a six week course of enrofloxacin and lesions did not recur. CONCLUSIONS AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first report of a pastern vasculitis associated with MRPA and successfully treated with a six week course of enrofloxacin.
