Abstract
Proliferative and necrotising otitis externa (PNOE) is a very rare disease affecting the ear canals and concave pinnae of kittens. This report describes a 5-month-old cat with PNOE. Histopathological examination confirmed the diagnosis. Treatment was initiated with local injection of methylprednisolone acetate into the lesions. The cat was subsequently treated with clobetasol propionate cream, a potent topical glucocorticoid ointment. The cat showed marked improvement. While topical treatment with tacrolimus, an immunosuppressive agent, is reported to be an effective therapy, to the best of our knowledge, this is the first report to treat PNOE with local corticosteroid therapy.
