2. TWO TYPES OF SALIVARY GLANDS TUMORS

3. BENIGN SALIVARY GLAND TUMORS
About 75% to 80% of major gland tumors are
benign, and 50% to 55% of minor gland tumors
are benign.
Types
• The pleomorphic adenoma (most common)
• Warthin tumor
• The monomorphic adenoma

4. THE PLEOMORPHIC ADENOMA
• The most common salivary gland tumor
• The mean age of occurrence is 45 years
• In the major glands, mostly in parotid gland
• in the minor glands the most common in the palate
• slow-growing, painless masses
• The treatment is complete surgical excision

5. WARTHIN TUMOR
• affects the parotid gland, specifically the tail
• The mean age of occurrence is 60 years
• Associated with smoking
• slow-growing, soft, painless mass
• The treatment is simple surgical excision

6. THE MONOMORPHIC ADENOMA
• Affecting mostly the upper lip minor glands
• The mean age of occurrence is 61 years
• asymptomatic, freely movable mass
• The treatment is simple surgical excision

7. MALIGNANT SALIVARY GLAND TUMORS
Doctors usually give salivary cancers a grade (from low to high), based on
how abnormal the cancers look under a microscope.
• The low-grade lesions have a 95% 5-year survival rate, whereas the
• high-grade lesions have less than a 40% 5-year survival rate.
Types
 The mucoepidermoid carcinoma
 The polymorphous low-grade adenocarcinoma
 The adenoid cystic carcinoma

8. THE MUCOEPIDERMOID CARCINOMA
• the most common malignant salivary gland tumor
• This tumor makes up 10% of major gland tumors (mostly parotid)
and 20% of minor gland tumors (mostly palatal)
• the mean age is 45 years
• submucosal mass that may be painful or ulcerated
• The treatment is wide surgical excision, local radiation therapy

9. THE POLYMORPHOUS LOW-GRADE ADENOCARCINOMA
• the second most common salivary gland malignancy
• The most common site is the junction of the hard and soft palates
• The mean age of 56 years
• slow-growing, asymptomatic masses, may become ulcerated
• The treatment is wide surgical excision

10. THE ADENOID CYSTIC CARCINOMA
• The third most common salivary gland malignancy
• The mean age of 53 years
• 50% occur in the parotid gland, whereas the other 50% occur in palate
• slow-growing, nonulcerated masses, with chronic dull pain
• The treatment is wide surgical excision, radiation therapy

11. PAROTIDECTOMY
Deep Lobe Parotidectomy
