Abstract: Objective Skin tumor is one of the most common tumors in veterinary medicine, and is probably the most common histopathological specimen sent to the diagnostic laboratory, and is often submitted for histopathological evaluation. Method From 2018 to 2019, a total of 39 cases of tumors originated from skin hair follicles were examined in dogs from different units. Pathological diagnosis and analysis were carried out on the 39 cases of tumors, and the tumor types, age, gender, benign and malignant, dog breeds and other aspects were analyzed in order to explore the rule and pathological characteristics of tumors originated from skin hair follicles in dogs. Result The highest incidence of hair follicle tumors was trichoblastoma (73%) , and the most common type in dogs was the ribbon type. In terms of benign and malignant tumors, the incidence of benign tumors is very high, accounting for 97%. The incidence of hair follicle-derived tumors in dogs tends to increase with age, and the incidence of these tumors is higher in older dogs. The occurrence of tumors originating from skin follicles did not show significant gender preference. Conclusion It can be used as a reference for the diagnosis and differential diagnosis of tumors originated from skin follicles.
