Description
Summary:	This is the first report of equine nasal rhinosporidiosis in Mineiros, Goiás, diagnosed through the histopathological analysis of granulomatous masses removed from a horse’s nostril of a 12-year-old male horse, through a surgical procedure. Microscopy revealed a papillomatous tissue lesion covered by moderately hyperplastic squamous epithelium, rich, loose fibrocollagenous tissues, well vascularized, accompanied by an accentuated inflammatory reaction constituted by a mixture of macrophages, lymphocytes, plasmocytes, and smaller number of neutrophils, and numerous round to oval structures with a unilamellar wall and a central nucleus surrounded by basophilic granular material, which were morphologically compatible with Rhinosporidium spp. sporangia.
