A rare case of spp. dermatitis in a horse is presented. After unrelated, previous surgery and antibiotic treatment, a saddle horse showed well-circumscribed areas of non-pruritic alopecia. Suspecting allergic skin disease, the horse was treated with corticosteroids. The skin lesion spread, and a second veterinarian was consulted. At clinical examination, the horse was lethargic, pyretic and hair was shedding/easily epilated over the head, neck, shoulders, and legs and the hind legs were swollen. Blood analysis revealed mild leucocytosis and hyperglobulinemia. Hair, skin scraping, and skin biopsy ruled out parasites and bacteria; cytology identified yeast-like structures with hyphae or pseudohyphae. was isolated on culture. Treatment consisted of stable disinfection, topical application of an antifungal solution, vitamins C and E supplementation and allowing the horse to graze in sunlight for at least 6 h/day. At 3-weeks follow-up, the horse had gained weight, alopecia was decreased, and all other clinical parameters were normal. Antifungal treatment was continued twice a week for three months. This study suggests may cause skin lesions in horses after long-term use of corticosteroids or antibiotics. To avoid unnecessary and prolonged suffering in cases of dermatitis, veterinarians should be promptly consulted, appropriate diagnostic procedures conducted, so that a definitive diagnosis can be reached, and an appropriate treatment regimen implemented.
本文报告了一例马的罕见性皮炎病例。在进行了无关的既往手术和抗生素治疗后，一匹鞍马出现了边界清晰的非瘙痒性脱毛区域。怀疑是过敏性皮肤病，该马接受了皮质类固醇治疗。皮肤病变扩散，于是咨询了另一位兽医。临床检查时，这匹马精神萎靡、发热，头部、颈部、肩部和腿部的毛发脱落/易拔除，后腿肿胀。血液分析显示轻度白细胞增多和高球蛋白血症。毛发、皮肤刮片和皮肤活检排除了寄生虫和细菌；细胞学检查发现了带有菌丝或假菌丝的酵母样结构。培养分离出了[具体菌种未给出]。治疗包括马厩消毒、局部应用抗真菌溶液、补充维生素C和E，并让马每天在阳光下放牧至少6小时。在3周的随访中，马体重增加，脱毛减少，所有其他临床参数均正常。抗真菌治疗持续每周两次，共三个月。本研究表明，[具体菌种未给出]在长期使用皮质类固醇或抗生素后可能导致马的皮肤病变。为避免皮炎病例中不必要的长期痛苦，应及时咨询兽医，进行适当的诊断程序，以便做出明确诊断并实施适当的治疗方案。
