The aim of this study was to determine the prevalence of cutaneous neoplasms in horses treated at the Center for the Development of Livestock at the Federal University of Bahia, as well as to correlate it with the coat color, breed, and age of the animal. For that, the attendance records for the last ten years were reviewed. When evaluating the files, 13 cases of cutaneous tumor in horses confirmed by histopathology and cytology were observed. The most prevalent skin tumors were sarcoid (38.5%), melanoma (23%), and fibrosarcoma (15.4%). Regarding the equine coat color, gray and sorrel horses were the most frequent with 30.7% and 23.1% of cases, respectively. As for the equine breed, the mangalarga marchador was the most prevalent (38.4%). Regarding age, 38.46% of the horses were up to 5 years old, 30.77% of the animals were between 4 and 10 years old, and 30.76% were between 11 and 16 years old. In the end, it can be concluded that sarcoid and melanoma were the most prevalent neoplasms.
