犬猫肺乳头状腺癌的病理学诊断

Pathological diagnosis of canine and cat lung papillary adenocarcinoma

犬和猫的肺乳头状腺癌作为犬和猫肺腺癌的一种病理亚型，目前还缺乏相关病理学诊断依据。采用2015版WHO肺肿瘤组织学分类方法，对临床犬和猫的肺癌进行病理学诊断。本次研究以患病犬类和猫类为样本，通过多取材，细观察，精确选取肿瘤组织样品，制备石蜡切片，然后石蜡切片经HE染色及免疫组织化学方法进行组织学鉴定。观察比较肿瘤组织和正常组织的病理形态，观察病理切片的细胞异型性，以此对犬和猫的肺乳头状腺癌进行病理学诊断，得出了4例病犬和病猫的病理学检查结果，均为肺乳头状腺瘤。

Pulmonary papillary adenocarcinoma of dogs and cats,as a pathological subtype of aaeno- carcinoma of canine and cat lung,is still lack of relevant pathological diagnosis. Pathological diag-nosis of lung cancer in clinical dogs and cats was performed using the 2015 WHO Lung rumor Classifica- t/on. In this study,the diseased dogs and cats were taken as samples. The paraffin sections were pre- pared by multi-drawing,observing and accurately selecting the tumor tissue samples. The paraffin sec- tions were identified by HE staining and immunohistochemistry. The histopathology of the tumor tissue and normal tissue was observed and the cell atypia of the pathological section was observed to diagnose the pathological diagnosis of lung papillary adenocarcinoma in dogs and cats. In conclusion,4 sick cases of dogs and cats are pulmonary papillary adenoma.
