Resumo: | The objective of this work was to study the epidemiology and distribution of equine sarcoid lesions diagnosed at the Laboratório Regional de Diagnóstico of UFPel (LRD/UFPel) over a period of 20 years, as well as to determine the main types and, the molecular identify of the bovine papillomavirus (BPV) associated to the lesions. Cases received between 2000 and 2020 were retrieved from the laboratory's necropsy protocols. The paraffin blocks of each case were cut into 3-5µm sections, stained with hematoxylin and eosin (HE) and reassessed under an optical microscope. The samples sent to the laboratory in 2021 were fixed in 10% formalin for histopathology and immunohistochemistry and, an aliquot of frozen tissues were sent to the Laboratory of Virology and Immunology (LabVir/UFPel) for PCR. During the study period, 258 cases were diagnosed, of which 75.96% in the Crioula breed, mainly in horses aged two to five years (42.64%). The macroscopic characteristics associated with the histopathology allowed us to determine the type of sarcoid in each case. In 46.8% of the cases, the sarcoids were fibroblastic. Of the 258 cases, 61% were single, mainly observed in the limbs, and 32% were multiple, most often present in the trunk. The BPV genome was not detected by PCR and the IHC was negative for protein S-100 and positive for vimentin, allowing the differential diagnosis of other equine cutaneous neoplasms. The record of 258 cases of equine sarcoid for approximately 20 years has contributed significantly to understand its epidemiology in southern Rio Grande do Sul and revealed the importance of the disease in the studied region. |

Los casos recibidos entre 2000 y 2020 se recuperaron de los protocolos de necropsia del laboratorio. Los bloques de parafina de cada caso se cortaron en secciones de 3-5 µm, se tiñeron con hematoxilina y eosina (HE) y se reevaluaron al microscopio óptico. Las muestras enviadas al laboratorio en 2021 fueron fijadas en formol al 10% para histopatología e inmunohistoquímica y parte fue congelada y enviada al Laboratorio de Virología e Inmunología de la UFPel (LabVir/UFPel) para PCR. En el período fueron diagnosticados 258 casos, de los cuales el 75,96% en la raza Crioula, principalmente en equinos de dos a cinco años (42,64%). Las características macroscópicas asociadas a la histopatología permitieron determinar el tipo de sarcoide en cada caso. En el 46,8% de los casos las sarcoides eran fibroblásticas. De los 258 casos, el 61% fueron únicos, principalmente observados en las extremidades, y el 32% fueron múltiples, con mayor frecuencia presentes en el tronco. El genoma del BPV no fue detectado por PCR y la IHC fue negativa para proteína S-100 y positiva para vimentina, lo que permitió el diagnóstico diferencial de otras neoplasias cutáneas equinas. El registro de 258 casos de sarcoide en 20 años permitió establecer su epidemiología en la región sur de Rio Grande do Sul y alerta sobre la importancia de la enfermedad en la región.Os objetivos deste trabalho foram estudar a epidemiologia e a distribuição das lesões de sarcoide equino diagnosticado no Laboratório Regional de Diagnóstico da UFPel (LRD/UFPel) em um período de 20 anos, bem como determinar os principais tipos e, por meio da PCR, identificar o papilomavirus bovino (BPV) envolvido nas lesões.
