Overview
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. The average age at diagnosis is 24.9 years in hereditary cases and 43.9 years in sporadic cases with men and women equally affected.[1]
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] and 500 to 1600 cases in the United States per year [2] but autopsy series discovered numbers higher that those of prevalence rates. 10% of pheochromocytomas are discovered by chance. null 22
Pheochromocytomas occur all races but less in black. Approximately 10% occur in children. Fifty percent of pheochromocytomas in children are solitary intra-adrenal lesions, 25% are present bilaterally, and 25% are extra-adrenal.
Most catecholamine-secreting tumors are sporadic. However, 30% of patients got the tumor as a part of familial disease, the catecholamine-secreting tumors are more likely to be bilateral.
Age
The peak incidence of pheochromocytoma occurs in third to fifth 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.
Gender
Men and women are equally affected by pheochromocytoma.[1]
