Abstract:
Equine testicular arteritis commonly occurs as a consequence of the migration of nematode larvae or equine arteritis virus (EAV) infection. However, testicular arteritis without evidence of these infections has been reported, and the underlying pathogenesis remains unclear. We encountered testicular arteritis without evidence of nematode or EAV infection in a 3-year-old male heavy draft horse with scrotal enlargement. Grossly, the volume of the pampiniform plexus was markedly increased due to edema. Histologically, non-suppurative and necrotizing testicular arteritis, characterized by lymphocyte infiltration and fibrinoid necrosis of the arterial walls, was diffusely observed in the spermatic cord, pampiniform plexus (most severe), testis, and epididymis. We were unable to identify the cause of arteritis, such as a viral infection or autoimmune abnormality.
摘要:
马睾丸动脉炎通常是由于线虫幼虫或马动脉炎病毒(EAV)感染的迁移而发生的。然而,睾丸动脉炎没有这些感染的证据已经报道,和潜在的发病机制仍不清楚。在3岁的雄性重马阴囊肿大的情况下,我们遇到了睾丸动脉炎,没有线虫或EAV感染的证据。严重的,由于水肿,Pampiniform丛的体积显着增加。组织学上,非化脓性和坏死性睾丸动脉炎,以淋巴细胞浸润和动脉壁的纤维蛋白样坏死为特征,在精索中弥漫性观察到,盘状神经丛(最严重),睾丸,还有附睾.我们无法确定动脉炎的病因,如病毒感染或自身免疫异常。
