Abstract Fifty‐one masked palm civets ( Paguma larvata ) were trapped as part of a nuisance wildlife control programme between July 2001 and August 2002 in Fujisawa City, Kanagawa Prefecture, Japan. Eleven civets had characteristic mange lesions with marked alopecia and crusts, caused by the burrowing epidermal mite Notoedres cati. The diagnosis was confirmed by histology and examination of mites obtained from skin scrapings of affected civets. Histopathology of lesions demonstrated moderate hyperplastic epidermis, parakeratosis and acanthosis. Occasionally microvascular angiogenesis was observed in the epidermis. Tunnels were excavated in the hair follicles, reaching the hair roots. The tunnels were located between the hair shaft and the inner root sheath. Female mites, eggs and nymphs were demonstrated in their tunnels using scanning electron microscopy.
