Which factor is a risk in developing pheochromocytoma?

• A. A history of skin cancer
• B. A history of high blood pressure
• C. A family history of adrenal tumors
• D. A family history of migraine headaches

Answer: (C)

A key idea is that pheochromocytoma often occurs in the context of inherited genetic syndromes. When there is a family history of adrenal tumors, it suggests a hereditary predisposition (such as MEN2, von Hippel-Lindau disease, neurofibromatosis type 1, or SDHx mutations) that increases the risk of developing pheochromocytoma. These syndromes involve adrenal or paraganglionic tumors and are a recognized risk factor for pheochromocytoma. The other options don’t point to a known hereditary risk for pheochromocytoma. A history of skin cancer isn’t specifically linked to pheochromocytoma risk, and hypertension or a history of migraines are more often symptoms or consequences or coincidental findings rather than factors that predispose someone to developing the tumor. If such a hereditary pattern is present, targeted screening may be considered due to the genetic association.
