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:
- Sialadenitis - inflammation
- Sialolithiasis - crystal formation and obstruction of salivary ducts
- Sialocoele - cyst formation
- Necrotizing sialometaplasia (salivary gland necrosis)
Salivary gland tumors are uncommon in dogs, with an overall incidence of 0.17%. 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.
