Background: Cutaneous lesions in horses are common, accounting for approximately 50% of all neoplasms of this species, and can cause irritability, pruritus and predispose to secondary infections. Studies have provided information of frequency of cutaneous neoplasms in horses, but few included non-neoplastic lesions. The aim of this study is to identify the frequency of cutaneous lesions in horses diagnosed in Southern Brazil, through a retrospective study and identification of the anatomic location of the lesion, the breed, gender and age of the animals affected. Materials, Methods & Results: A retrospective study on skin lesions in horses using the database of the Veterinary Pathology Laboratory located in Southern Brazil was carried out from January 2000 to February 2013. Cases were searched for and selected by diagnosis, considering age, breed, gender, location and time of occurrence. The most common lesions included sarcoid, exuberant granulation tissue, squamous cell carcinoma (SCC), pythiosis, habronemiasis, melanoma, papillomatosis and Culicoides hypersensitivity. The most affected age range for sarcoid was animals from 1 to 5 years of age and for SCC was over 15 years of age. There was a positive association between sarcoid occurrence and being female and between SCC and habronemiasis and being male. Sarcoid, exuberant granulation tissue, pythiosis and habronemiasis[...](AU)
