Description : Paragangliomas, also referred to as 'glomus body tumors,' are tumors derived from
paraganglia located throughout the body. Nonchromaffin types primarily serve as chemoreceptors
(hence, the tumor name 'chemodectomas') and are located in the head and neck region
(i.e., carotid body, jugular, vagal, and tympanic regions), whereas chromaffin types
have endocrine activity, conventionally referred to as 'pheochromocytomas,' and are
usually located below the head and neck (i.e., adrenal medulla and pre- and paravertebral
thoracoabdominal regions). PGL can manifest as nonchromaffin head and neck tumors
only, adrenal and/or extraadrenal pheochromocytomas only, or a combination of the
2 types of tumors (Baysal, 2002; Neumann et al., 2004). The triad of gastric leiomyosarcoma,
pulmonary chondroma, and extraadrenal paraganglioma constitutes a syndrome that occurs
mainly in young women and is known as the Carney triad (604287). This triad is not
to be confused with the other Carney syndrome of myxoma, spotty pigmentation, and
endocrinopathy (160980). Baysal (2008) provided a review of the molecular pathogenesis
of hereditary paraganglioma. - Genetic Heterogeneity of Paragangliomas See also PGL4
