| Abstract: | 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. |
