Plain-English summary
A 12-year-old female domestic longhair cat was brought to the vet for frequent sneezing and a painful, swollen bump on her nose. Tests revealed she had a rare fungal infection called sporotrichosis, specifically caused by a type of fungus known as Sporothrix humicola. The cat also had diabetes, which was managed with insulin and diet. After starting treatment with oral itraconazole, the lesions on her nose cleared up completely after a year, and she tolerated the medication well.

Abstract
Case summary A 12-year-old female neutered indoor–outdoor domestic longhair cat presented with frequent sneezing and a nodular, suppurative lesion on its dorsal nose. Histopathological examination revealed a fungal granuloma. PCR and sequencing of the ribosomal internal transcribed spacers (ITS) regions (ITS-F and ITS-R) confirmed an infection with a Sporothrix species. Further sequencing of the beta-tubulin and calmodulin genes confirmed Sporothrix humicola , which lies within the Sporothrix pallida complex. The cat had concurrent diabetes mellitus, which responded to insulin therapy and diet. Oral itraconazole at 10 mg/kg PO q24h resulted in resolution of the lesions after 12 months. Treatment was well tolerated. Relevance and novel information This is the first report of sporotrichosis in a cat in the UK and only the fifth worldwide involving the S pallida complex. Clinicians, pathologists and microbiologists need to be aware of the potential of Sporothrix infections in the UK and the ability of S pallida complex to cause opportunistic infections. Molecular techniques can achieve rapid and accurate identification of rare fungal organisms. A precise diagnosis with molecular testing can provide information regarding prognosis, treatment and zoonotic implications.
