We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA) in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals), located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum. According to clinical and pathological findings, the tumour has been defined as a low grade mixed nasal adenocarcinoma, with the presence of tubular and papillary structures. This is, to our knowledge, the first report of ENA in Algeria known to be associated with enzootic nasal tumour virus (ENTV) infection. However, such association requires confirmation by direct and/or indirect viral investigation.
我们报告了阿尔及利亚一只绵羊的地方性鼻腺癌（ENA）的临床和病理特征。一只来自阿尔及利亚博尔杰布阿雷里季一个大羊群（约1240只动物）的一岁乌尔德杰拉尔绵羊，临床上表现为持续性浆液性鼻分泌物、摇头、舔鼻、呼吸困难、眼球突出和额部突出，据此做出诊断。该绵羊实施安乐死后进行了尸检。大体检查显示鼻腔内有质地柔软、粉白色的肿瘤块，鼻甲和鼻中隔变形。根据临床和病理检查结果，该肿瘤被定义为低级别混合性鼻腺癌，存在管状和乳头状结构。据我们所知，这是阿尔及利亚首例已知与地方性鼻肿瘤病毒（ENTV）感染相关的ENA报告。然而，这种关联需要通过直接和/或间接病毒检测来确认。
