In adults, 90% tumors are located unilaterally and are solitary, and 10% are located outside the adrenal gland. In children 50% are adrenal, while 25% are bilateral and 25% are extraadrenal. The common extradrenal locations are the abdomen, thorax and urinary bladder. | |||

Overview
Pathophysiology
Traditionally it is known as the "10% tumor":
- bilateral disease is present in approximately 10% of patients
- approximately 10% of tumours are malignant
- approximately 10% are located in chromaffin tissue outside of the adrenal gland
- Approximately 10% arise in childhood
- Approximately 10% are familial
- Approximately 10% recur after being resected
- Approximately 10% patients do not have hypertension (Campbell's Urology)
Tumor Location
In adults, 90% tumors are located unilaterally and are solitary, and 10% are located outside the adrenal gland. In children 50% are adrenal, while 25% are bilateral and 25% are extraadrenal. The common extradrenal locations are the abdomen, thorax and urinary bladder.
