Overview
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%
Prevalence
- The incidence/prevalence of [disease name] is approximately [number range] per 100,000 individuals worldwide.
- In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
- The prevalence of [disease/malignancy] is estimated to be [number] cases annually.
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
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)
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
