Fungal disease is included in the differential diagnosis of a wide range of disorders in cats. At the Department of Veterinary Pathology of Federal University Federal of Rio Grande do Sul (SPV-UFRGS), evaluation of records data of cats from January 2005 to December 2015 were examined. A total of 1,274 necropsy have been reviewed from which 17 cases of fungal infection was revealed accounting for 1.33%, and a total of 2,615 biopsies have been reviewed from which 59 cases of fungal infection was revealed, accounting for 2.25%. We retrospectively analyzed the gross and microscopic findings and the yield of additional diagnostic approaches employed. Sporotrichosis was the most common diagnosis with 34 cases found in biopsy and five necropsies. Cryptococcosis obtained six diagnoses through necropsy and 13 through biopsy. Dermatophytic pseudomycetoma was found in five cases in biopsy and two necropsies. Histoplasmosis diagnosis was obtained in one necropsy and two biopsies. Aspergillosis had two cases diagnosed in necropsy. Candidiase and phaeo-hyphomycosis accounted for one case each. In four occasions, it was not possible to identify the agent involved and the diagnosis was made regarding the morphological changes: fungal dermatitis, fungal enteritis, mycotic rhinitis, and fungal dermatitis and osteomyelitis. In this study, sporotrichosis could be identified as the most frequent diagnosis of fungal disease in cats, followed by cryptococcosis and dermatophytic pseudomycetoma. |
