Cutaneous habronemosis in horses is caused by larvae of the spirurid nematodes and . These lesions, also known as "summer sores'', are often severe and disfiguring. Although -caused lesions at the coronary grooves have been described, cases of hoof cracks with secondary summer sores have never been reported. The present case describes clinic-pathological and surgical features of a quarter crack case complicated by cutaneous habronemosis at the dermal layers. A 15-year-old, Andalusian stallion was referred to the Veterinary Teaching Hospital of the University of Teramo because of a mass of the hoof and a severe lameness. The clinical examination revealed an exuberant granulation tissue protruding from a full thickness vertical quarter crack. The mass was surgically removed, and subjected to histopathological, microbiological, and parasitological analyses. A copromicroscopic examination was also performed. The feces scored PCR positive for , while the skin for both and , thus confirming the primary role of in causing the hoof mass. This is the first description of a hoof wall crack complicated by summer sores, with simultaneous gastric habronemosis. This case confirms that a prompt diagnosis during fly activity is imperative for an efficacious treatment and a timely prevention of disfiguring summer sores.
马的皮肤柔线虫病由旋尾目线虫的幼虫引起。这些病变，也被称为“夏季溃疡”，通常很严重且会毁容。尽管已经描述过由该病引起的冠状沟病变，但蹄裂并发继发性夏季溃疡的病例从未被报道过。本病例描述了一例蹄裂病例的临床病理和手术特征，该病例在真皮层并发皮肤柔线虫病。一匹15岁的安达卢西亚种公马因蹄部肿物和严重跛行被转诊至泰拉莫大学兽医教学医院。临床检查发现一个从全层垂直蹄裂处突出的增生性肉芽组织。肿物被手术切除，并进行了组织病理学、微生物学和寄生虫学分析。还进行了粪便显微镜检查。粪便PCR检测显示 呈阳性，而皮肤检测 和 均呈阳性，从而证实了 在引起蹄部肿物中的主要作用。这是首次描述蹄壁裂缝并发夏季溃疡且同时伴有胃柔线虫病的病例。该病例证实，在苍蝇活动期间迅速诊断对于有效治疗和及时预防毁容性夏季溃疡至关重要。
