Infecção cutânea disseminada por Sporothrix schenckii em um canino

Abstract

Sporotrichosis is a mycotic disease of subacute or chronic evolution, caused by the dimorphic fungus Sporothrix schenckii, which affects humans and several species of animals, thus being classified as a zoonosis. This fungus has a worldwide distribution, but is more common in temperate and tropical regions, developing well in hot and humid places. This mycosis is reported more frequently in cats, which have an important epidemiological role, whereas in dogs the disease is considered uncommon. This study describes a case of S. schenckii infection in a dog diagnosed by fine needle aspiration cytology (CAAF) of the lesions and later confirmed by histopathological examination. The aim of this report is to demonstrate the importance of cytological evaluation as a diagnostic tool. In addition, we sought to raise the attention of the Veterinary Medicine professional to consider sporotrichosis as a differential diagnosis in canine dermatopathies, to emphasize to the owners of affected animals the need to carry correctly the treatment. In addition, our aim is also to warn that the permanence of the studies aimed at a better understanding of this disease, as well as the performance of the administrative and health authorities in the planning of prophylaxis and control measures.
