犬皮肤毛囊的肿瘤病理诊断及分析

Pathological Diagnosis and Analysis of Hair Follicle Tumors in Dogs

目的犬皮肤毛囊肿瘤是兽医临床中最常见的肿瘤之一,可能也是送往诊断实验室最常见的组织病理学标本,经常被送检要求进行组织病理学评估。单纯靠临床特征进行诊断具有局限性,本文旨在对此类肿物进行系统的组织病理学分类,以期和临床大体特征结合,进行更准确更高效的诊断。方法对2018—2019年不同单位送检的犬皮肤毛囊的肿瘤(共39例)进行病理学诊断和分析,并对犬的品种、年龄、性别、肿瘤类别和性质等方面进行分析,旨在探讨犬皮肤毛囊的肿瘤发生的规律和病理学特点。结果皮肤毛囊的肿瘤中,发病率最高的为毛母细胞瘤,占比73%,在犬中最常见的类型为缎带型。从发生的肿瘤性质来看,良性肿瘤发生率很高,占比97%。从发病年龄来看,发病率随着年龄的增长而有升高的趋势,即老年犬多发。从发病性别来看,肿瘤的发生没有表现出明显的性别偏好性。结论为今后犬皮肤毛囊的肿瘤诊断与鉴别诊断提供参考。

Objective Skin tumor is one of the most common tumors in veterinary medicine,and is probably the most common histopathological specimen sent to the diagnostic laboratory,and is often submitted for histopathological evaluation.Method From 2018 to 2019,a total of 39 cases of tumors originated from skin hair follicles were examined in dogs from different units.Pathological diagnosis and analysis were carried out on the 39 cases of tumors,and the tumor types,age,gender,benign and malignant,dog breeds and other aspects were analyzed in order to explore the rule and pathological characteristics of tumors originated from skin hair follicles in dogs.Result The highest incidence of hair follicle tumors was trichoblastoma(73%),and the most common type in dogs was the ribbon type.In terms of benign and malignant tumors,the incidence of benign tumors is very high,accounting for 97%.The incidence of hair follicle-derived tumors in dogs tends to increase with age,and the incidence of these tumors is higher in older dogs.The occurrence of tumors originating from skin follicles did not show significant gender preference.Conclusion It can be used as a reference for the diagnosis and differential diagnosis of tumors originated from skin follicles.
