J Pak Med Assoc Jan ;66(1):104-6.

Paraganglioma originates from chromaffin cells of adrenal medulla and autonomic paraganglia, which are derived from the neural crest cells. Paragangliomas are half as common as pheochromocytomas with 69% occurring in head and neck, 22% in abdomen and pelvis and 10% in the thorax. About 70% paragangliomas are sporadic, 30% are hereditary, having identifiable germline mutations of Succinate Dehydrogenase enzyme (SDH).
