Core Tip

Core Tip: Paragangliomas are widely distributed and have diverse clinical manifestations. Although most paragangliomas are benign, the malignancy is involved in approximately 10% of paragangliomas. The traditional treatment of malignant paragangliomas is surgery to the primary site. Surgery followed by adjuvant radiation is used less frequently, and chemotherapy is typically reserved for the distant disease. This study indicated the diagnostic features and therapeutic strategies of malignant paraganglioma. Therapeutic strategies for malignant paragangliomas are lacking. After the initial treatment, the patient’s progression-free survival reached 21 mo. Subsequently, the patient progressed and was treated again with chemoradiotherapy, surgery, and targeted therapy.
