Q

Most malignant familial pheochromocytomas are of what gene type?

A

SDHB

25
Q

__________ lesions of pheochromocytoma or association with medullary hyperplasia suggest genetically linked syndrome and hence lesions in other organs.

A

bilaterality/multifocal –> especially true if pt <40 //must consider family disease

26
Q

Pheochromocytoma malignancy is only defined by
