“…In the histopathological examination, R. seeberi is observed at all stages of development, and it is not possible to correlate some specific form of evolutionary stage with clinical presentation [34]. The literature describes some histological findings associated with infection, citing squamous metaplasia and epithelial hyperplasia [9, 19, 25].…”

BackgroundOculosporidiosis (ocular rhinosporidiosis) accounts for 15% of cases of rhinosporidiosis, which is a chronic granulomatous disease and is endemic in India and Sri Lanka. In Brazil, the climatic and hydrographic similarities to these endemic areas and the presence of riverside populations contributes to an increase in the incidence of rhinosporidiosis particularly in the State of Maranhão. This study, therefore, aimed to identify the number of diagnosed cases of oculosporidiosis and describe its the clinical epidemiology, laboratory, histopathology, and therapeutic characteristics.MethodsThe study is descriptive, observational, and cross-sectional, and reports the prevalence and clinical epidemiological characteristics of oculosporidiosis in the State of Maranhão, Brazil. A retrospective analysis of the paper and electronic records for a period from 1999 to 2017 was conducted in the University Hospital of Federal University of Maranhão (HU-UFMA), located in the northeastern region of Brazil.ResultsThirty patients were diagnosed with rhinosporidiosis, eight of them had oculosporidiosis and seven of these met the criteria to be included in the study. Of the cases (23.3% of all 30), five were men (71.4%) and two women (28.5%), with an average age of 16.4 ± 15.6 years. In terms of race, four patients (57.1%) declared themselves white and three (42.9%) as brown. The north of the state, the mesoregion, had the most diagnosed cases accounting for 57.1% of the total. Left eye was the most affected site, reported in six patients (85.7%), while the conjunctiva was affected in all patients. Rhinosporidiosis and papilloma were the predominant diagnostic hypotheses (28.5 and 28.5%, respectively), followed by chronic scleritis, granuloma, and chalazion (14.25, 14.25, and 14.25%, respectively). All these cases were treated with lesion excision, and only two patients (28.5%) progressed with recurrence.ConclusionIt was verified that there was a male predominance, with only one eye reported as an infected site, with no bilateral involvement. The younger age group (between 1 and 2 years of age) was more affected by oculosporidiosis, and histopathological examination was necessary for a conclusive diagnosis.

“…As in other large case series, patients were predominantly male and aged < 30 years. 1,9,47,64,65 Ocular involvement predominated in our case series, probably due to the participation of a large, national reference ophthalmology clinics in our country. Most case series report nasal predominance, 8,9 although some describe a variation of anatomic presentation according to gender.…”

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.

“…The importance of diagnosing this case is highlighted, as it awakens to the existence of sources of infection, as well as cultural and environmental characteristics of the Northeast region, which include the accumulation of water in dams, high temperatures and humidity, which possibly favor the perpetuation and development of this etiological agent, increasing the possibility of occurrence of the disease. It is noteworthy that in the Northeast region there is a description of the disease in humans, mainly in the states of Maranhão, Piauí and Bahia (Abud & Pereira, 2007;Silva et al, 1975;Vallarelli et al, 2011), suggesting that the disease also occurs in animals, but possibly has not been diagnosed.…”

“…In Brazil, although the disease occurs sporadically, there are reports of the disease in the southern region in cattle (Riet-Correa et al, 1983) and horses (Argenta et al, 2018;Bernardo et al, 2016;Sampaio et al, 2018;Santos et al, 2014), and in the southeast region in dogs (Neves et al, 2014) and horses (Zibordi et al, 2020). In the Northeast, the disease is frequent in humans (Abud & Pereira, 2007;Silva et al, 1975), but there are no descriptions in animals. Therefore, the objective is to describe the clinical, epidemiological and anatomopathological aspects of a case of nasal rhinosporidiosis in a horse in the Northeast region of Brazil.…”

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.
