National Cancer Data Base report on malignant paragangliomas of the head and neck

Abstract

Malignant paraganglioma represents metastatic spread of a tumor type that, when restricted to the site of origin, is considered benign. Metastases from malignant paragangliomas of the head and neck usually are regionally confined. The primary management of a recognized malignancy should be directed toward complete surgical removal of the primary tumor and regional lymph nodes. Postoperative irradiation may be beneficial in slowing the progression of residual disease.
