Dysgonic strain of Microsporum canis pseudomycetoma in a Domestic Long‐hair cat

Abstract

A 4-year-old Domestic Long-hair cat was presented with two large non-painful, ulcerated and suppurative lesions over the flanks. Histopathology and cytology were consistent with fungal pyogranulomatous inflammation. Culture of tissue yielded a dysgonic strain of Microsporum canis. The cat was treated successfully by staged en bloc resections of the lesions, followed by oral ketoconazole, then oral terbinafine. This is the first reported case of dermatophytic pseudomycetoma in a Domestic Long-hair cat in Australia.
