犬耳部肿物病理诊断及分析

摘要: 目的对32 例犬耳部肿物进行病理学诊断和分析，探讨犬耳部肿瘤发生的规律。方法将中国农业大学教学动物医院2009 ～ 2015 年进行过手术治疗的32 例犬耳部肿物，制成切片，根据病理学观察进行诊断并对其组织来源、年龄、发生部位及品种进行分析。结果犬耳部毛母细胞瘤和组织细胞瘤发生比率均各占26. 7%; 犬耳部肿瘤在0 ～ 4. 9 岁个体中发生率占20%，5 ～ 9. 9 岁占40%，≥10 岁占40%; 肿瘤均发生于外耳，中耳和内耳未见; 在品种方面，发生率较高的是可卡犬共8 例，其余品种均为2 ～ 3 例。结论犬耳部好发毛母细胞瘤和组织细胞瘤，且发病率随年龄增长呈上升趋势，但组织细胞瘤例外。耳部肿瘤易发在可卡犬品种，均发生在外耳。

Pathological Diagnosis and Analysis of Canine Ear Tumors

Abstract: Objective 32 cases of canine ear tumors were pathologically diagnosed and analyzed to explore the occurrence regularity． Method The canine ear tumors were obtained from China Agricultural University Animalhospital from 2009 to 2015 by surgical treatment，which were analyzed according to pathological diagnose the occurrence regularity of the location，tissue origin，age and breed． Ｒesult The occurrence rate of trichoblastoma and histiocytoma in canine ear were each accounted for 26. 7%． Canine ear tumors occurred in 0 － 4. 9 years old accounted for 20%，5 － 9. 9 years old accounted for 40%，more than 10 years old accounted for 40%． The Tumors all occurred in the external ear，but not in middle ear and inner ear． From the breed，the high incidence was 8 cases of Cocker Spaniel，other varieties were 2 － 3 cases． Conclusion Trichoblastoma and histiocytoma were the often occurred in the canine ear and there was an upward trend of incidence on canine ear tumors with age increase but not on histiocytoma． All the tumors were occurred in the external ear and often occurred in Cocker Spaniel．
