E-mail: fabiobernardo104@gmail.com Rhinosporidiosis is a chronic infection characterized by the growth of polypoid structures in mucous membranes. The etiologic agent is Rinosporidium seeberi currently recognized as a protist parasite. It is suspected to be a water saprophyte which allows transmission through contact with contaminated water or even through inhalation, and this means mainly associated with human infection. Considering few cases described in Brazil and the need to better understand the epidemiology The aim of this study is to report a case of rhinosporidiosis on a horse two years. The animal, from the city of Pelotas, was treated at the Veterinary Clinical Hospital of the Universidade Federal de Pelotas, Rio Grande do Sul, where demonstrated sneezing and serous bilateral nasal discharge. Medial septal region in the left nostril there was the presence of granulomatous nodules polypoid with about three cm in diameter. The same friable consistency and reddish with small whitish granules. Since clinical parameters and blood counts were within the reference values for the species; and changes in airway endoscopy not were observed. Carried out surgical excision of the tumor mass by injecting local anesthesia and general anesthesia, dorsal buccal branch of the facial nerve. The procedure was performed with Allis clamp and scalpel aid and subsequent cauterization of the implantation base with liquid nitrogen. Mass of the fragments were immersed in 10% formalin for histopathology. Approximately 15 days after the procedure, the surgical wound had completely healed. Histologically there was numerous structures compatible with sporangia R. seeberi in different stages of maturation, amid immature connective tissue and intense inflammation where macrophages and polymorphonuclear predominant cells (neutrophils and eosinophils). The lesion formed by inflammatory response against the parasite, said clinical signs demonstrated by the horse due to partial obstruction of air flow and mucosal irritation. Already the whitish granules observed in macroscopic match agent sporangia. The clinical, macroscopic and histological findings were similar to other reports, but have been found cases with more severe clinical course including difficulty breathing and involvement of the lower anatomical structures of the respiratory system, such as larynx. Surgical resection of the mass has excellent results and excellent prognosis; however, there may be late relapses requiring prolonged follow-up. This was the second case of the disease diagnosed in the same neighborhood of the city. This leads to suspect source of infection at the site and reinforces the need to investigate the agent’s presence in the environment, such as spore detection in stagnant water, as well as conduct seroepidemiological studies; thus contributing to the understanding of the epidemiology, still not very clear, this disease. In conclusion, clinical signs, pathology and viewing of R. seeberi sporangia were enough to confirm the diagnosis. In addition, it must include the rhinosporidiosis the differential diagnosis of other diseases of the respiratory system of horses in the southern region of the State. |

Seu agente etiológico é Rinosporidium seeberi atualmente reconhecido como um parasito protista. Suspeita-se que seja um saprófita da água o que permite sua transmissão pelo contato com água contaminada ou até mesmo através da inalação, sendo esta via associada principalmente com infecção em humanos. Tendo em vista poucos casos descritos no Brasil e a necessidade de melhor conhecer sua epidemiologia o objetivo deste trabalho é relatar um caso de rinosporidiose em um equino de dois anos, sem raça definida. O animal, proveniente da cidade de Pelotas, foi atendido no Hospital de Clínicas Veterinária da Universidade Federal de Pelotas, Rio Grande do Sul, onde demonstrou espirros e secre- ção nasal serosa bilateral. Medialmente na região do septo nasal na narina esquerda verificou-se a presença de um nódulo polipoide granulomatoso com aproximadamente três cm de diâmetro. O mesmo apresentou consistência friável e coloração avermelhada com pequenas granulações esbranquiçadas. Sendo que os parâmetros clínicos e o hemograma estavam dentro dos valores de referência para a espécie; e na endoscopia das vias aéreas não foram observadas alterações. Realizou-se exérese cirúrgica da massa tumoral através de anestesia geral injetável e bloqueio local do ramo bucal dorsal do nervo facial. O procedimento foi realizado com auxílio de pinça de Allis e bisturi e posterior cauterização da base de implantação com nitrogênio líquido. Fragmentos da massa foram imersos em formol 10% para histopatologia. Aproximadamente 15 dias após o procedimento, a ferida cirúrgica apresentou cicatrização completa. Na histologia verificaram-se numerosas estruturas compatíveis com esporângios de R. seeberi, em diferentes está- gios de maturação, em meio a tecido conjuntivo imaturo e intenso infiltrado inflamatório onde predominavam macrófagos e células polimorfonucleares (neutrófilos e eosinófilos). A lesão, formada pela reação inflamatória frente ao parasita, explica os sinais clínicos demonstrados pelo equino devido obstrução parcial do fluxo de ar e irritação da mucosa. Já as granulações esbranquiçadas verificadas na macroscopia correspondem aos esporângios do agente. Salienta-se que os achados clínicos, macroscópicos e histopatológicos foram semelhantes a outros relatos, porém já foram encontrados casos com curso clínico mais severo incluindo dificuldade respiratória e acometimento de estruturas anatô- micas mais inferiores do sistema respiratório, como laringe. A ressecção cirúrgica da massa possui excelentes resultados e ótimos prognósticos; porém, podem ocorrer recidivas tardias o que exige acompanhamento prolongado do caso. Ressalta-se que este foi o segundo caso da enfermidade diagnosticado no mesmo bairro da cidade. Isso leva a suspeitar da existência de fonte de infecção no local e reforça a necessidade de investigar a presença do agente no ambiente, como a detecção de esporos em água estagnada, bem como realizar estudos soroepidemiológicos; contribuindo, desta forma, para o conhecimento da epidemiologia, ainda não bem esclarecida, desta enfermidade. Conclui-se que os sinais clínicos, a patologia e a visualização dos esporângios de R. seeberi foram suficientes para confirmar o diagnóstico. Além disso, deve-se incluir a rinosporidiose como diagnóstico diferencial de outras afecções do sistema respiratório de equinos na região Sul do Estado.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2016-06-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rbmv.org/BJVM/article/view/234Brazilian Journal of Veterinary Medicine; Vol. 38 No. 2 (2016); 175-180Revista Brasileira de Medicina Veterinária; v. 38 n. 2 (2016); 175-1802527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/234/158Bernardo, Fábio DarlanPazinato, Fernanda MariaAlves, Carlos Eduardo FonsecaBueno, Verônica La CruzFranciscato, CarinaElias, Fabianainfo:eu-repo/semantics/openAccess2020-12-23T17:26:02Zoai:ojs.rbmv.org:article/234Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2020-12-23T17:26:02Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
