To categorize histologic lesions affecting the tongue, determine the frequency with which they develop, and identify risk factors associated with their development in dogs.
Retrospective case series.
1,196 dogs.
Diagnostic reports of lingual biopsy specimens from dogs evaluated from January 1995 to October 2004 were reviewed.
Neoplasia comprised 54% of lingual lesions. Malignant tumors accounted for 64% of lingual neoplasms and included melanoma, squamous cell carcinoma, hemangiosarcoma, and fibrosarcoma. Large-breed dogs, especially Chow Chows and Chinese Shar-Peis, were at increased risk for melanoma. Females of all breeds and Poodles, Labrador Retrievers, and Samoyeds were more likely to have squamous cell carcinomas. Hemangiosarcomas and fibrosarcomas were commonly diagnosed in Border Collies and Golden Retrievers, respectively. Benign neoplasms included squamous papilloma, plasma cell tumor, and granular cell tumor. Small-breed dogs, especially Cocker Spaniels, were at increased risk for plasma cell tumors. Glossitis accounted for 33% of diagnoses; in most cases, the inciting cause was not apparent. Whereas large-breed dogs were more likely to have lingual neoplasia, small-breed dogs were more likely to have glossitis. Calcinosis circumscripta accounted for 4% of lingual lesions and predominately affected young large-breed dogs. The remaining submissions consisted mostly of various degenerative or wound-associated lesions.
The frequency of lingual lesions was not evenly distributed across breeds, sexes, or size classes of dogs. Veterinarians should be aware of the commonly reported lingual lesions in dogs so that prompt diagnosis and appropriate management can be initiated.
对影响犬舌部的组织学病变进行分类，确定其发生频率，并识别与犬舌部病变发生相关的风险因素。
回顾性病例系列研究。
1196只犬。
回顾了1995年1月至2004年10月间接受评估的犬舌活检标本的诊断报告。
肿瘤构成舌部病变的54%。恶性肿瘤占舌部肿瘤的64%，包括黑色素瘤、鳞状细胞癌、血管肉瘤和纤维肉瘤。大型犬，尤其是 Chow Chow犬和中国沙皮犬，患黑色素瘤的风险增加。所有品种的雌性犬以及贵宾犬、拉布拉多寻回犬和萨摩耶犬更易患鳞状细胞癌。血管肉瘤和纤维肉瘤分别常见于边境牧羊犬和金毛寻回犬。良性肿瘤包括鳞状乳头瘤、浆细胞瘤和颗粒细胞瘤。小型犬，尤其是可卡犬，患浆细胞瘤的风险增加。舌炎占诊断病例的33%；在大多数情况下，诱发原因不明。大型犬更易患舌部肿瘤，而小型犬更易患舌炎。局限性钙质沉着症占舌部病变的4%，主要影响年轻的大型犬。其余病例大多为各种退行性或与伤口相关的病变。
舌部病变的发生频率在犬的品种、性别或体型类别中分布不均。兽医应了解犬常见的舌部病变，以便能及时诊断并进行适当处理。
