Paragangliomas may arise in any area of the body where nonchromaffin paraganglia are situated. These include the glomus jugulare, the carotid body, and the retroperitoneum. Malignant behavior of these paragangliomas has been a controversial subject with most authors, who consider them to be benign tumors. Some authors have diagnosed locally recurrent and infiltrative tumors as malignant, whereas most require the demonstration of metastatic potential as the only criterion for malignancy. Two cases of metastasizing carotid body tumors are reported with a review of the literature on this unusual neoplasm.
副神经节瘤可发生于身体中非嗜铬性副神经节所在的任何部位。这些部位包括颈静脉球、颈动脉体和腹膜后。这些副神经节瘤的恶性行为一直是一个有争议的话题，大多数作者认为它们是良性肿瘤。一些作者将局部复发和浸润性肿瘤诊断为恶性，而大多数作者则要求将转移潜能的证明作为恶性的唯一标准。本文报告了两例转移性颈动脉体瘤，并对有关这种罕见肿瘤的文献进行了综述。
