Localised microsphaeropsis arundinis infection of the subcutis of a cat.

Unlabelled: CLINICAL PRESENTATION AND DIAGNOSIS: An 11-year-old spayed domestic crossbred cat was presented for two focal lesions affecting the subcutis that developed 3 weeks after a cat fight. Lesions consisted of swelling of the subcutaneous tissues over the bridge of the nose and a focal swelling of the dewclaw pad of the left thoracic limb. Both lesions were attributable to localised infections with the unusual fungal pathogen Microsphaeropsis arundinis, based on direct microscopy of smear cytology, histology, fungal culture, internal transcribed spacer-polymerase chain reaction (ITS-PCR) and sequence analysis of formalin-fixed tissue and colonial material from primary culture.
