An 18-month-old Friesian heifer had several unusual, raised, black, cutaneous plaques, some of which were up to 20 cm in diameter, on its head and neck, limbs, thorax and perineum. There was also generalised lymphadenopathy. A clinical diagnosis of lymphosarcoma (sporadic bovine leukosis) was derived from a fine needle aspiration of a skin lesion. Post mortem and histological examinations confirmed a multicentric lymphosarcoma with widespread infiltration into many of the tissues recognised as predilection sites for this type of tumour. However, in the authors' experience, the presence of tumour masses in the trachea and the right mainstem bronchus was atypical.
一头18个月大的弗里斯兰小母牛在其头部、颈部、四肢、胸部和会阴处长有几块异常的、凸起的黑色皮肤斑块，其中一些直径达20厘米。还存在全身性淋巴结病。通过对皮肤病变进行细针穿刺，临床诊断为淋巴肉瘤（散发性牛白血病）。尸检和组织学检查证实为多中心性淋巴肉瘤，广泛浸润到许多被认为是这类肿瘤好发部位的组织中。然而，根据作者的经验，气管和右主支气管中出现肿瘤块并不常见。
