Abstract:

The aim of this study was to carry out pathological diagnosis of different types of canine ovarian tumors, summarize and analyze their histopathological features, and provide reference for precise diagnosis of canine ovarian tumors. Cases of canine ovarian tumors diagnosed at the National Laboratory for Detection of Bovine Transmissible Spongiform Encephalopathy of the School of Zoology, College of Agricultural Sciences, China Agricultural University, and their detailed case information were retrospectively selected for histopathological diagnosis, and the characteristics of the cases and their morbidity were summarized. Results were as follows: Seven cases of ovarian epithelial tumors were diagnosed, including four cases of ovarian papillary adenoma, one case of ovarian papillary adenocarcinoma, one case of ovarian reticulum adenoma, and one case of ovarian reticulum cystadenoma; and eight cases of ovarian gonadal mesenchymal tumors were diagnosed, including three cases of ovarian granulosa cell tumor, one case of follicular membranous cell tumor, and four cases of luteoma. Dogs over 11 years of age accounted for 33.3% of all cases. These results showed that the incidence of ovarian epithelial tumors and gonadal mesenchymal stromal tumors were comparable, and the epithelial tumor with the highest incidence rate was ovarian papillary adenoma, while luteoma and granulosa cell tumors were frequent among gonadal mesenchymal stromal tumors; the prevalence rate of the old dogs was high, and the rate of prevalence increased with the increase of age; the occurrence of ovarian tumors had no significant correlation with the breeds of the dogs.
