Overview
The annual incidence of pleomorphic adenoma is approximately 2-3.5 cases per 100,000 population. It accounts for 45-75% of all salivary gland neoplasms. Females are more commonly affected than males.
Epidemiology and Demographics
Incidence
- The annual incidence of pleomorphic adenoma is approximately 2-3.5 cases per 100,000 population.[1]
- It accounts for 45-75% of all salivary gland neoplasms.
- Pleomorphic adenoma distribution among the salivary glands is as follows[2]:
- Parotid gland: 84%
- Submandibular gland: 8%
- Minor salivary glands: 6.5%
Age
- People of all age groups may develop pleomorphic adenoma.[1]
- The incidence of pleomorphic adenoma increases with age; the average age at diagnosis is 43-46 years.
Race
- There is no racial predilection to pleomorphic adenoma.
Gender
- Females are predominantly affected by pleomorphic adenoma than males. The female to male ratio is approximately (2:1)[1]
