Abstract：
Autoimmune dermatopathies are not common in horses. These autoimmune diseases can be idiopathic or triggered by an antigen such as drugs, vaccines, or neoplasia. The most common one is pemphigus foliaceus, which manifests as a pustular, crusting eruption. Other more common pustular diseases should be ruled out before considering pemphigus. Vasculitis is relatively common in horses and can be triggered by a variety of antigenic stimulations. Systemic lupus and true idiopathic autoimmune vasculitis are very rare in horses. Every effort should be made to reach a final diagnosis, as the prognosis for true idiopathic autoimmune skin diseases is poor.
摘要：
自身免疫性皮肤病在马中并不常见。这些自身免疫性疾病可以是特发性的或由抗原如药物引发的，疫苗,或者瘤形成。最常见的是天疱疮，表现为脓疱，地壳喷发.在考虑天疱疮之前，应排除其他更常见的脓疱病。血管炎在马中相对常见，并且可以由多种抗原刺激引发。系统性狼疮和真正的特发性自身免疫性血管炎在马中非常罕见。应该尽一切努力做出最终诊断，作为真正的特发性自身免疫性皮肤病的预后较差。
