Abstract: Rhinosporidiosis is a chronic infectious disease caused by the agent Rhinosporidium seeberi, which mainly affects the mucous membranes and can affect several species of animals. Although it has a worldwide distribution, this disease has rarely been described in dogs. This article describes a case of nasal rhinosporidiosis in a dog in the city of Eldorado do Sul in the state of Rio Grande do Sul. The dog, a male, mixed-breed, about five years old was rescued from the streets with clinical signs of sneezing, bleeding and purulent nasal secretion. Visual inspection identified a polyp on the mucosa of the left nasal cavity. A portion of the polyp was expelled through sneezing. The fragment was collected, fixed in 10% buffered formalin, processed histologically and subjected to Hematoxylin and Eosin, Periodic acid-Schiff and Gomori trichrome staining. Histopathology revealed granulomatous inflammation associated with sporangia at different stages of maturation. The clinical, macroscopic and microscopic findings were compatible with nasal rhinosporidiosis. The rest of the lesion regressed spontaneously and there have been no reports of recurrence to date.Downloads
