“…organisms are larger and form single endospores, which are characterized by presenting uninucleate, spherical conidia, measuring 10-20 µm in diameter for E. parva and up to 300 mm for E. crescens (Caswell & Williams, 2016). PAS staining evidenced the capsule and internal granules of the endospores and has been used to identify the agent in nasal mycoses in humans Research, Society and Development, v. 11, n. 12, e99111234075, 2022 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v11i12.34075 (Boni et al, 2002) and horses (Sampaio et al, 2018), as well as to differentiate from C. immitis, which stain only the capsule of the endospores (Jones et al, 2000).…”

The objective of this study is to describe the clinical, epidemiological and anatomopathological aspects of a case of nasal rhinosporidiosis in a horse in the Northeast of Brazil. A 15-year-old female horse of mixed breed presented a nodule in the mucosa of the right nasal septum. Surgical excision was performed and sent for histopathological examination. Macroscopically, the nodule had an irregular and reddish surface, and when cut it was soft, whitish, and polypoid in shape. Microscopically, myriads of sporangia with endospores inside were observed in the lamina propria, morphologically similar to Rhinosporidium seeberi in various stages of maturation. The structures were also evidenced and marked by periodic acid Schiff (PAS), Grocott methenamine silver (GMS) and toluidine blue. The diagnosis of rhinosporidiosis was made based on macroscopic aspects and confirmed through histopathological examination. The presence of myriads of sporangia measuring 115 to 220 µm, containing endospores in its interior allowed the diagnosis. Although rhinosporidiosis is considered rare in Brazil, in the Northeast region there are descriptions of the disease in humans, suggesting that the disease in animals occurs and has possibly not been diagnosed. Therefore, it is important to include it as a differential diagnosis of diseases that affect the nasal cavity of horses in the region and that present similar lesions.

“…The vast majority of rhinosporidiosis cases have been reported from India, Pakistan and Sri Lanka. 1 In North and South America, including Colombia, cases have been reported from 12 countries, 10,30–61 but only Paraguay and north-eastern Brazil are considered endemic areas. 46,59…”

Rhinosporidiosis is a chronic granulomatous disease that affects mucosal surfaces. Its epidemiology and clinical presentation in Colombia are not well-known. We therefore reviewed all 58 reported cases between 1964 and 2015 to raise awareness among clinicians in a non-endemic area. Of the patients, 64% were male (median age = 15 years) and 57% had ocular and 43% nasal manifestations; there were no disseminated cases of the disease. All lesions were surgically removed.

“…As lesões oculares são geralmente unilaterais e apresentam-se na forma de uma estrutura pedunculada ou séssil, móvel, com aspecto granular, coloração rosada ou avermelhada, e geralmente aderida ao fórnice ou conjuntiva tarsal (9)(10) . O envolvimento de outras estruturas oculares, como carúncula, limbo, margem palpebral, vias lacrimais e esclera já foi relatado, porém com menor freqüência (6)(7) .…”
