Salivary gland

From Dog

Canine salivary glands are accessory glands located throughout the oral cavity and include the parotid, mandibular, sublingual and zygomatic glands.

A number of diseases of the salivary glands have been reported in dogs, including:

- Salivary gland adenoma
- Salivary gland carcinoma
- Angiolipoma[2]

Salivary gland tumors are uncommon in dogs, with an overall incidence of 0.17%[3]. Primary malignant epithelial tumors are the most frequently diagnosed.

Malignancies are locally infiltrative and metastasis to regional lymph nodes is common. Distant metastasis has been reported, although very few.

Salivary gland tumors include adenocarcinomas, carcinomas, adenomas, mixed tumors and rarely carcinosarcomas[4], malignant myoepitheliomas[5] and osteosarcomas[6].
