Benign salivary gland tumorsAbout 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 tumorThe monomorphic adenoma

The pleomorphic adenoma

The most common salivary gland tumorThe mean age of occurrence is 45 yearsIn the major glands, mostly in parotid glandin the minor glands the most common in the palate slow-growing, painless massesThe treatment is complete surgical excision

Warthin tumoraffects the parotid gland, specifically the tail The mean age of occurrence is 60 yearsAssociated with smokingslow-growing, soft, painless massThe treatment is simple surgical excision

The monomorphic adenoma

Affecting mostly the upper lip minor glands The mean age of occurrence is 61 yearsasymptomatic, freely movable massThe treatment is simple surgical excision

Malignant salivary gland tumors

Doctors usually give salivary cancers agrade(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 thehigh-grade lesions have less than a 40% 5-year survival rate.

Types The mucoepidermoid carcinoma The polymorphous low-grade adenocarcinoma The adenoid cystic carcinoma

The mucoepidermoid carcinoma

the most common malignant salivary gland tumorThis tumor makes up 10% of major gland tumors (mostly parotid) and 20% of minor gland tumors (mostly palatal)the mean age is 45 yearssubmucosal mass that may be painful or ulceratedThe treatment is wide surgical excision, local radiation therapy

The polymorphous low-grade adenocarcinoma

the second most common salivary gland malignancyThe most common site is the junction of the hard and soft palatesThe mean age of 56 yearsslow-growing, asymptomatic masses, may become ulceratedThe treatment is wide surgical excision

The adenoid cystic carcinoma

The third most common salivary gland malignancyThe mean age of 53 years50% occur in the parotid gland, whereas the other 50% occur in palateslow-growing, nonulcerated masses, with chronic dull painThe treatment is wide surgical excision, radiation therapy
