title: Multiple simultaneous paragangliomas of the head and neck in association with multiple retroperitoneal pheochromocytomas.
abstract: A patient in whom multiple, familial, catecholamine-secreting head and neck paragangliomas and retroperitoneal pheochromocytomas were identified is reported. There were at least nine primary and possibly five recurrent neoplasms, the most reported in a single patient. In patients with family history of pheochromocytoma or paraganglioma or with multiple tumors, careful laboratory and angiographic studies are indicated to discover additional lesions.
