Plain-English summary
A young adult cat was brought in with severe ear problems, specifically a rare condition called proliferative and necrotising otitis externa, which affected both ear canals but not the outer ear. The vet used a special camera to look inside the ears and found unusual growths throughout the ear canals. After confirming the diagnosis with a tissue sample, the cat was treated with a daily application of a diluted ointment, which led to a complete recovery.

Abstract
Proliferative and necrotising otitis externa is a rare and recently described disease affecting the ear canals and concave pinnae of kittens. This article describes a case of proliferative and necrotising otits externa in a young adult cat. In this case, the lesions did not affected the pinnae, but both ear canals were severely involved. Video-otoscopy revealed a digitally proliferative lesion, growing at 360° all around the ear canals for their entire length, without involvement of the middle ear. Histopathological examination confirmed the diagnosis, and the cat responded completely to a once-daily application of 0.1% tacrolimus ointment diluted in mineral oil in the ear canals. Video-otoscopy findings, not described previously, were very peculiar and may help clinicians to diagnose this rare disease.
