Plain-English summary
A Domestic Longhair cat developed a lump on its tail that turned out to be a type of infection caused by a bacteria called Nocardia. The mass was made up of inflamed tissue and bacteria that were identified through advanced testing. This case is notable because it's the first time this specific bacteria, Nocardia tenerifensis, has been found in a pet with skin issues. Treatment details weren't provided, but identifying the bacteria is crucial for determining the right care.

Abstract
An adult Domestic Longhair cat developed a subcutaneous mass in its tail. Histologically, this mass consisted of ill-defined pyogranulomas centered around aggregates of gram-positive, acid-fast filamentous bacteria, consistent with Nocardia. Due to the lack of fresh samples, DNA was extracted from formalin-fixed paraffin-embedded tissue sections and subjected to polymerase chain reaction amplification and DNA sequencing of 16S ribosomal RNA gene encompassing Nocardia sp.-specific sequences. Sequences analyzed using the GenBank database revealed 99.5% homology with Nocardia spp. and had the highest sequence homology of 98.2% with Nocardia tenerifensis among Nocardia spp. To the authors' knowledge, this is the first report of detection of N. tenerifensis genome associated with cutaneous nocardiosis in an animal.
