Pheochromocytomas and paragangliomas (collectively referred to as PPGLs) are rare tumors that originate from chromaffin cells in the adrenal medulla (pheochromocytoma) or in the extra-adrenal neural ganglia (paraganglioma). These tumors can be either biochemically active (producing a catecholamine like epinephrine, nor-epinephrine and dopamine) or biochemically silent. PPGLs can be either sporadic or genetic, with association to several familial syndromes. PPGLs can also be classified according to their spread into local, regional, or metastatic. The defining characteristic of malignancy in PPGLs is the presence of metastasis.
