Overview

Paraganglioma may be classified into several subtypes based on the site of origin and presence of neural cells.

Classification

According to the World Health Organization, paragangliomas are classified based on the presence of neural cells. Paragangliomas are also described by their site of origin and are often given special names:

• Carotid paragangliomas
• Glomus tympanicum and Glomus jugulare paragangliomas
• Vagal paragangliomas
• Other sites, such as larynx, nasal cavity, paranasal sinuses, thyroid gland, thoracic inlet, as well as the bladder in extremely rare cases.
