Paraganglioma is a rare benign tumor that origins from cells of the paraganglia. Paraganglia are a collection of cells that came from embryonic nervous tissue, and are found near the adrenal glands and some blood vessels and nerves.

Overview of paraganglioma
Paraganglioma is a rare benign tumor that origins from cells of the paraganglia. Paraganglia are a collection of cells that came from embryonic nervous tissue, and are found near the adrenal glands and some blood vessels and nerves. Paragangliomas that develop in the adrenal gland are called pheochromocytomas. Those that develop outside of the adrenal glands near blood vessels or nerves are called glomus tumors or chemodectomas.
Various terminology has been used in the past to describe these tumors based on their histopathologic and anatomical presentations. Glenner and Grimley’s classification scheme helped distinguish the adrenal paragangliomas from the extra-adrenal paragangliomas. The tumors are thus divided into adrenal paragangliomas or pheochromocytomas and extra-adrenal paragangliomas. The branchiomeric paragangliomas and intravagal paragangliomas are found in the head and neck and mediastinum1. Terms used in the past have included: glomus tumors, chemodectomas, carotid body tumors, and nonchromaffin tumors. Currently, the correct terminology is paraganglioma based on the anatomical location (e.g. carotid paraganglioma and jugulotympanic paraganglioma). Because the terms glomus tympanicum and glomus jugulare have persisted, they will be used to differentiate the jugulotympanic paragangliomas in this text.
