Plain-English summary
A cat with severe breathing problems, loss of appetite, and unusual aggression was found to have a serious fungal infection called Trichosporon loubieri. During the examination, the vet noticed multiple painful skin sores on the cat's body. Tests, including X-rays and ultrasounds, revealed fluid in the chest and growths in the chest area. Unfortunately, despite identifying the infection through skin biopsies and cultures, the cat was euthanized due to the severity of the illness.

Abstract
Our study describes a case of systemic Trichosporon loubieri infection in a cat with acute dyspnea, anorexia, and aggressiveness. Physical examination revealed multiple ulcerative cutaneous lesions on the abdomen, neck, and thorax. Thoracic radiographs and ultrasound showed multiple mediastinal nodules and marked pleural effusion, respectively. A cutaneous biopsy from the ulcerated wounds revealed necrogranulomatous dermatitis and panniculitis with numerous intralesional fungal hyphae. Fungal culture on fresh swab samples from the cutaneous lesions yielded growth of a fungal organism that was further identified as Trichosporon loubieri by PCR and DNA sequencing. The cat was subsequently euthanized and submitted to autopsy. Gross pathology changes consisted of multifocal to coalescing white nodules ranging from 5 to 10 mm in diameter that expanded the mediastinal fat, intrathoracic lymph nodes, lungs, and costal pleura. These lesions consisted of areas of necrogranulomatous inflammation with numerous intralesional fungal hyphae morphologically similar to those observed in the cutaneous biopsy sample. Gross and histologic changes were consistent with a systemic fungal infection, and the etiologic diagnosis was supported by fungal culture. Fungal identity was confirmed by DNA sequencing of D1-D2 and TS1 regions.
