Infection of the subcutis of the nose in a cat caused by Mucor species:: successful treatment using posaconazole

A 14-year-old neutered female domestic shorthair cat was presented for investigation of a non-painful subcutaneous swelling of the nasal dorsum at the site of a scratch injury. Cytological evaluation demonstrated a granulomatous reaction and many variably shaped organisms consistent with yeasts/fungi. Subsequent biopsy and culture yielded a pure growth of a Mucor species. The cat was treated with the second-generation triazole antifungal agent posaconazole for 5 months. Complete resolution was seen with no recurrence 12 months after discontinuing treatment.
