Paraganglioma (or chemodectoma) arise in the head and neck region most commonly in the carotid body, glomus tympanicus and glomus jugulare. They are extremely rare in the nasopharynx with about 20 cases described (for review see [101]), but need to be considered when profuse haemorrhage and a pulsatile mass are encountered in the nasopharynx. These slowly enlarging, painless, firm, encapsulated tumours are characterised by nests (so-called Zellballen) of small to medium-sized pale monomorphous cells with prominent, rounded hyperchromatic nuclei and a prominent network of en-dothelial cell lined vascular channels (see also Chaps. 8 and 9).
