Salivary gland diseases are well characterized in human medicine but are uncommonly reported in dogs. Herein we describe the clinical and pathologic features of 179 canine salivary gland biopsy submissions to the Athens Veterinary Diagnostic Laboratory from 2010 to 2018. The mean age of affected dogs was 8.5 y; no sex or breed predisposition was evident. The main reason for sample submission was regional swelling (107 cases; 59.7%). Extraoral (major) salivary glands were affected in 125 cases (69.8%), and oral (minor) salivary glands were affected in 43 cases (24% of cases). The location of the lesion (extraoral or oral) was not specified in 11 cases (6.1%). The diagnoses included nonspecific sialoadenitis (89 cases; 49.7%), normal salivary gland (42 cases; 23.4%), neoplasia (36 cases; 20.1%), salivary gland lipomatosis (7 cases; 3.9%), necrotizing sialometaplasia (4 cases; 2.2%), and traumatic hemorrhage (1 case; 0.5%). Most cases of sialoadenitis (63 cases), neoplasia (23 cases), and lipomatosis (5 cases), as well as all cases of necrotizing sialometaplasia and the only case of traumatic hemorrhage, affected extraoral glands. Most neoplasms (32 cases, 88.8% of the tumors) were epithelial and malignant, followed by round cell tumors (2 cases; 5.5%), a carcinosarcoma (1 case; 2.7%), and a tumor of undetermined histogenesis (1 case; 2.7%).

唾液腺疾病在人类医学中具有很好的特征，但在狗中很少见。在此，我们描述了2010年至2018年间向雅典兽医诊断实验室提交的179例犬唾液腺活检的临床和病理学特征。患病狗的平均年龄为8.5岁。没有明显的性别或品种易感性。提交样本的主要原因是区域肿胀（107例； 59.7％）。口腔（大）唾液腺受累125例（69.8％），口腔（小）唾液腺受累43例（24％）。11例（6.1％）未明确病变的位置（口腔外或口腔）。诊断包括非特异性唾液腺炎（89例； 49.7％），正常唾液腺（42例； 23.4％），瘤形成（36例； 20.1％），唾液腺脂肪瘤病（7例； 3.9％），坏死性唾液腺增生症（4例； 2.2％）和创伤性出血（1例； 0.5％）。唾液腺炎的大多数病例（63例），肿瘤（23例）和脂肪瘤病（5例），以及所有坏死性唾液腺增生症和唯一的创伤性出血病例，都影响口腔外腺。多数肿瘤（32例，占肿瘤的88.8％）是上皮性和恶性的，其次是圆形细胞肿瘤（2例； 5.5％），癌肉瘤（1例； 2.7％）和组织发生不确定的肿瘤（1例； 5例）。 2.7％）。
