Plain-English summary
Three kittens, all female domestic short hair, were brought in for treatment of a rare ear condition called proliferative and necrotizing otitis externa (PNOE), which caused thick, crusty lesions around their ears and eyelids. The first kitten needed medication, including topical tacrolimus and oral prednisolone, after a short course of ciclosporin, while the other two kittens showed improvement on their own without treatment. This case highlights the importance of careful examination for skin lesions in kittens with ear problems, as they may be easily overlooked.

Abstract
BACKGROUND: Proliferative and necrotising otitis externa (PNOE) is a rare disorder in cats with poorly understood pathogenesis. Extra-auricular (EA) lesions recently have been mentioned in a textbook and in one case report. OBJECTIVES: To describe EA lesions associated with PNOE in three kittens. ANIMALS: A 6-month-old female domestic short hair (DSH) cat (Case 1), an 8-month-old female DSH cat (Case 2) and a 5-month-old female DSH cat (Case 3). METHODS AND RESULTS: All cases exhibited classical lesions of PNOE associated with EA lesions, generalised (cases 1 and 3) or limited to eyelids (Case 2). Lesions were characterised by thick, adherent, hyperkeratotic papules coalescing to plaques and attempts to remove the hyperkeratotic plaques resulted in erosions. Histopathological examinations revealed classical features of PNOE: severe acanthosis associated with a marked lymphocytic exocytosis, satellitosis and apoptotic keratinocytes at all levels of the epidermis and the outer root sheath of hair follicles. Cases 2 and 3 resolved spontaneously. Case 1 remained stable with topical tacrolimus and oral prednisolone after a short course of ciclosporin. CONCLUSIONS AND CLINICAL IMPORTANCE: This report describes EA lesions of PNOE in three kittens. Such lesions may be underdiagnosed, and this report emphasises the role of a thorough clinical inspection in PNOE cases.
