Overview
The incidence of pheochromocytoma ranges from a low of 0.2 per 100,000 persons to as high as 0.8 per 100,000 persons. The average age at diagnosis is 24.9 years in familial cases and 43.9 years in sporadic cases. Both men and women are affected equally by pheochromocytoma.
Epidemiology and Demographics
Incidence
- In the USA, the incidence of pheochromocytoma ranges from a low of 0.2 per 100,000 persons to a high of 0.8 per 100,000 persons.[1].
- Annually reported cases range from 500 to 1600 in the United States.[2]
- Autopsy studies have discovered a higher number of cases than the actual prevalence rates. Ten percent of pheochromocytomas cases are discovered by chance.
Prevalence
- The prevalence of pheochromocytoma in patients with hypertension in general outpatient clinics varies between 0.2 and 0.6%.
- The prevalence of pheochromocytoma is approximately 1.7% in children with hypertension.
- About 5% of patients with incidentally discovered adrenal masses on imaging actually have pheochromocytoma.
- The prevalence of pheochromocytoma in individuals carrying a germline mutation in pheochromocytoma susceptibility genes may be around 50%.
- Patients with hereditary pheochromocytoma typically present with multifocal disease and at a younger age than those with sporadic neoplasms.
Age
- The peak incidence of pheochromocytoma occurs in third decades of life; the average age at diagnosis is 24.9 years in hereditary cases and 43.9 years in sporadic cases.[1]
- Hereditary tumors present at a younger age than sporadic.
- Approximately 10% occur in children.
Race
- Pheochromocytomas occur across all races but is found less commonly in blacks.
Gender
- Both men and women are affected equally by pheochromocytoma.[1]
