摘要

马睾丸动脉炎通常是线虫幼虫迁移或马动脉炎病毒(EAV)感染的结果。然而,也有报道称睾丸动脉炎没有这些感染的证据,其潜在的发病机制仍不清楚。我们在一匹阴囊肿大的 3 岁雄性重型草马身上发现了没有线虫或 EAV 感染证据的睾丸动脉炎。从外观上看,由于水肿,睾丸静脉丛的体积明显增大。从组织学角度看,在精索、睾丸鞘膜丛(最严重)、睾丸和附睾弥漫性地观察到非化脓性坏死性睾丸动脉炎,其特征是淋巴细胞浸润和动脉壁纤维素性坏死。我们无法确定动脉炎的病因,如病毒感染或自身免疫异常。

Non-suppurative and necrotizing testicular arteritis in the male reproductive organs of a heavy draft horse.

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.
