According to the rule of 10s, what percentage of pheochromocytomas are familial?

Explanation:
The rule of tens states that about 10% of pheochromocytomas are familial or hereditary. This reflects cases linked to inherited syndromes such as MEN2, VHL, NF1, and SDH gene mutations. It also frames the other traditional ten-percent estimates—about 10% bilateral, about 10% malignant, and about 10% extra-adrenal—though newer genetic data can shift these numbers. So, the percentage describing familial cases is 10%.
