Abstract
ABSTRACT: A retrospective study of skin diseases diagnosed in cattle from 2000 to 2022 was performed at the “Laboratório Regional de Diagnóstico” of the “Faculdade de Veterinária” of the “Universidade Federal de Pelotas” (LRD-UFPel) to determine the main skin diseases that affect cattle in southern Brazil. Information regarding epidemiological data, lesions and diagnosis was collected. The diseases were grouped into infectious/inflammatory, toxic, nonneoplastic proliferative and neoplastic. The macroscopic aspects, distribution, histopathology, and evolution of the lesions were obtained in the protocols, and the original diagnosis was preserved. The main skin diseases diagnosed during this period occurred during outbreaks. They were infectious, with an emphasis on dermatophilosis, papillomatosis and dermatophytosis, followed by hepatogenous photosensitization, which was included in the group of toxic diseases. Among the neoplasms, squamous cell carcinoma stood out, occurring in isolated cases, reflecting an irrelevant cause of economic losses.
