paraganglioma

An uncommon neuroendocrine tumour often of the head and neck which arises in neural crest and is more common in women; 2 to 9% of carotid body, vagal body and jugulo-tympanic paragangliomas are malignant vs. 25% of those in the larynx. Paragangliomas are part of Carney’s triad (extraadrenal paraganglioma, GIST, pulmonary chondroma), and occur in von Hippel-Lindau syndrome..
 
Clinical findings
