犬睾丸原发性特有肿瘤的病理学观察与分析

Pathological Observation and Analysis of Specific Dog Primary Testicular Tumor

目的对三类犬睾丸原发性特有肿瘤进行病理学诊断和分析,探讨犬睾丸原发性肿瘤的病理学特点,为诊断睾丸原发性肿瘤提供资料。方法中国农业大学国家动物海绵状脑病实验室收集来自动物医院的临床犬睾丸肿物病例,从2013年至2015年共35例,制成切片,HE染色,根据病理学特征进行诊断与鉴别诊断、比较肿瘤细胞形态特征、根据组织学特点鉴别细胞起源,总结三类肿瘤的病理学特点和鉴别诊断要点。结果观察比较犬精原细胞瘤、支持细胞瘤、间质细胞瘤的组织病理学特征,总结犬睾丸肿瘤的临床特征,为今后该类肿瘤的诊断与鉴别诊断提供有效资料。结论精原细胞瘤、支持细胞瘤和间质细胞瘤为睾丸常见的原发性肿瘤,常见于老年犬,恶性睾丸肿瘤的发病率低。由于肿瘤细胞来源不同,呈现出不同的组织病理学特征。

Objective To three kinds of primary testicular tumor pathology diagnosis and analysis,unique canine testicular primary tumor pathological characteristics,provide data for the diagnosis of primary testicular tumor.Method China Agricultural University National Animal TSE Lab collected from China Agricultural University animal hospital clinical cases of testicular neoplasm,from 2013 to 2015,a total of 35 cases,and made into slices,H. E. dye,according to the pathology diagnosis and differential diagnosis,comparison,tumor cells morphological characteristics,according to the histological characteristics identification of cell origin,summarize the main points three kinds of pathological features and differential diagnosis of the tumor. Result compare histopathological features of dog seminoma,sertoli cell tumor and interstitial cell tumor,summarize the clinical features of testicular tumors,for the diagnosis and differential diagnosis of this tumor in the future to provide effective information.Conclusion seminoma,sertoli cell tumor and interstitial cell tumor for common primary testicular tumor,common in older dogs,low incidence of malignant testicular tumors. Due to the different tumor cell source,presents different histopathological features.
