Placa aural: revisão bibliográfica

Abstract

Papillomatous manifestations in infected horses can occur in six forms: sarcoid, squamous cell carcinoma, classic papillomatosis, genital papillomatosis, auricular papillomatosis, also known as aural plaque, and generalized papillomatosis. Aural plaque is a dermatological, viral, benign disease that affects the pinna of horses, unilaterally or bilaterally, isolated or multiple times. These lesions are whitish in color, in the shape of papules that may or may not coalesce, transforming into keratinized plaques. They may also have a warty appearance and extend over almost the entire surface of the pinna. This disease does not regress spontaneously and may cause management difficulties due to the auricular sensitivity generated. The diagnosis of the pathology can be based on the clinical appearance of the lesions, however, to identify the viral variety involved, the most used technique is the polymerase chain reaction (PCR), as it has a high sensitivity, which allows the identification of the agents. from viral isolation. The recommended treatment is based on the chemotherapy agent imiquimod® 5%, topically, however, this therapy is only indicated in cases of ear sensitivity. The review was carried out through research with different types of documents such as: articles, theses, dissertations, books and online texts. The objective of this review is to evaluate the most recent publications on aural plaque in order to present advances and significant practices on the subject, in addition to highlighting the importance of this disease in equine breeding stock.
