44例宠物犬肿瘤病理诊断及分析

收集北京地区2015~2016年宠物医院的部分宠物犬肿瘤病例56例，采用组织病理学方法进行病理诊断，并对患病动物的品种、发生部位、年龄和性别与肿瘤发生关系进行了统计分析。结果发现，56个病例中有44例确诊为肿瘤，其中良性肿瘤21例，包括肛周腺瘤、皮脂腺瘤和肥大细胞瘤等；恶性肿瘤23例，包括乳腺癌、鳞状上皮细胞癌和肛周腺癌等。本次采集的病例中，大型犬与小型犬发病率持平，皮肤、肛周与乳腺部位肿瘤的发生率较高；7岁以后是肿瘤高发期；雌性犬皮肤和乳腺肿瘤的患病率高于雄性，雄性宠物犬肛周腺肿瘤的发生率高于雌性，肿瘤总患病率雄性与雌性持平。本研究为今后宠物犬肿瘤的流行病学及诊断提供了新的参考资料。

Histopathologic Diagnosis and Analysis of 44 Cases of Pet Dog Tumors

56 cases of suspected tumor materials from a pet hospital in Beijing were collected from 2015 to 2016, the histopathological method was used for tumor diagnosis, then the varieties of onset, sites, age and gender of tumors were statically analyzed. The results showed that among the 56 cases, 44 cases were diagnosed as tumors. There were 21 cases of benign tumor, including rianalgland adenomas, sebaceous adenoma,mast cell tumor and so on. There were 23 cases of malignant tumors, including breast cancer, squamous cell cancer, adenocarcinoma of anus and so on. The results indicated that skin, perianal and breast had a higher incidence. The tumor onset rate became higher after 7 years old. The skin tumors and breast cancer were more common in female pet dog, however, the anal gland peripheral tumor onset rate of male pet dogs was higher. This study provided a reference for the epidemiology and diagnosis of canine tumors in the future.
