Plain-English summary

A 14-year-old female domestic shorthair cat had a painless swelling on her nose after getting scratched. Tests showed that the swelling was caused by a fungal infection from a type of mold called Mucor. The veterinarian treated her with a medication called posaconazole, an antifungal, for five months. After treatment, the swelling completely went away, and there were no signs of it returning even a year later.

Abstract

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.
