Non-neoplastic lesions of equine skin in the central United States and Canada: a retrospective study.

Abstract: A retrospective study evaluated the clinical data and histologic features of non-neoplastic dermatologic lesions in skin biopsies from horses, donkeys, and mules submitted over a 10-year period to the Colorado State University Diagnostic Medicine Center and to the University of Saskatchewan Western College of Veterinary Medicine and Prairie Diagnostic Services. A total of 1793 non-neoplastic biopsies were available for analysis. Based on the histologic description and morphologic diagnosis, each submission was classified as inflammatory, or non-neoplastic/non-inflammatory. Results of this study demonstrate that non-neoplastic equine cutaneous biopsies are predominantly inflammatory, but histopathology alone may not be sufficient to definitively identify the underlying etiologies driving inflammatory lesions. Clinical correlation, including breed, age, and distribution of the cutaneous lesion, as well as ancillary tests such as bacterial or fungal culture are required to complete the clinical picture and arrive at the appropriate clinical diagnosis. Une étude rétrospective a évalué les données cliniques et les caractéristiques histologiques des lésions dermatologiques non néoplasiques des biopsies cutanées de chevaux, d’ânes et de mules soumises pendant une période de 10 ans au Diagnostic Medicine Center de l’Université de l’État du Colorado, au College of Veterinary Medicine de l’Université de la Saskatchewan et à Prairie Diagnostic Services. Un total de 1793 biopsies non néoplasiques étaient disponibles aux fins d’analyse. En se fondant sur la description histologique et le diagnostic morphologique, chaque soumission a été classée comme inflammatoire ou non néoplasique/non inflammatoire. Les résultats de cette étude démontrent que les biopsies cutanées équines non néoplasiques sont surtout inflammatoires, mais que l’histopathologie seule peut ne pas être suffisante pour identifier définitivement les étiologies sous-jacentes des lésions inflammatoires. La corrélation clinique, incluant la race, l’âge et la distribution de la lésion cutanée ainsi que des tests auxiliaires, comme une culture bactérienne ou fongique, est requise pour achever le portrait clinique et parvenir à un diagnostic clinique approprié.(Traduit par Isabelle Vallières).

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article presents a retrospective study of non-neoplastic dermatologic lesions in horses, donkeys, and mules over a 10-year period, indicating that these skin biopsies are mainly inflammatory. It also emphasizes the need for additional tests to definitively identify the underlying causes of these inflammatory lesions.

Study Design and Participants

  • This is a retrospective study that collected and analyzed clinical and histologic data from skin biopsies of horses, donkeys, and mules.
  • These biopsies were taken over a ten-year period from two sources: the Colorado State University Diagnostic Medicine Center and the University of Saskatchewan’s Western College of Veterinary Medicine and Prairie Diagnostic Services.
  • A total of 1793 non-neoplastic biopsies were analyzed for this study.

Findings and Implications

  • The study found that the majority of non-neoplastic equine cutaneous biopsies are inflammatory.
  • However, the researchers found that using histopathology alone is not sufficient to definitively identify the causes of these inflammatory lesions.
  • In order to fully understand and diagnose the causes of these dermatologic conditions, additional tests and clinical correlations are required. These include factors such as the breed and age of the animal, the distribution of the lesions, and bacterial or fungal cultures.

Concluding Remarks

  • In conclusion, this study emphasizes the importance of comprehensive diagnostic processes for non-neoplastic equine cutaneous conditions.
  • While histopathological analyses provide crucial data, they should be supplemented with additional tests and clinical correlates for accurate diagnoses. This multifaceted approach can lead to more effective treatment plans for equine patients in the future.
