Fatal hypothermia represents a diagnostic challenge in veterinary pathology. Wischnewski spots (WS) and black oesophagus (BO) have been described in human cases of fatal hypothermia but rarely in animals. We now describe WS and BO in suspected fatal hypothermia in a free-ranging brown howler monkey (Alouatta guariba clamitans) and a pet rabbit (Oryctolagus cuniculus). Both animals had dark spots resembling WS on the gastric mucosa and the monkey also had BO with haematin deposition. In both cases, stress factors and relatively cold environmental conditions were present prior to death.

一只褐吼猴（Alouatta guariba clamitans）和一只兔子（Oryctolagus cuniculus）在疑似致命性低温症中出现 Wischnewski 斑点和黑色食道

致命的体温过低代表了兽医病理学的诊断挑战。Wischnewski 斑 (WS) 和黑色食道 (BO) 已在人类致命低温症病例中被描述，但在动物中很少见。我们现在描述一只自由放养的棕色吼猴 ( Alouatta guariba clamitans ) 和一只宠物兔 ( Oryctolagus cuniculus )在疑似致命低温下的 WS 和 BO 。两只动物的胃粘膜上都有类似 WS 的黑斑，猴子也有 BO 并伴有血红素沉积。在这两种情况下，在死亡之前都存在压力因素和相对寒冷的环境条件。
