This report describes a rare case of malignant paraganglioma metastatic to the mandible in a 22-year-old male patient diagnosed with retroperitoneal malignant paraganglioma and is accompanied by a review of the literature. Clinical examination at the first presentation to the Oral and Maxillofacial Surgery Department revealed a non-tender soft growing mass localized in the right mandibular angle. Intraoral examination revealed healthy oral mucosa without expansion and without malocclusion. CT showed that the right mandibular angle was compromised with lateral and medial soft tissue displacement. In addition, CT angiography revealed that the mass was highly vascular, with the external carotid artery serving as the main blood supply. After tumor resection, histopathology revealed malignant paraganglioma metastatic to the mandible. To our knowledge, this is the second case of malignant paraganglioma metastatic to the mandible to be reported in the literature.
