Introduction Pituitary adenomas (PA) and phaeochromocytomas/paragangliomas (phaeo/PGL) are relatively rare tumours. The prevalence of symptomatic PA in the general population is around 1 in 1000 ( Daly et al . 2006 , Fernandez et al . 2010 ). The

Introduction Phaeochromocytomas (PCs) are tumours in the adrenal medulla, and paragangliomas (PGLs) arise in extra-adrenal sympathetic chromaffin tissue or head and neck parasympathetic tissues. Familial occurrence of PGLs was first reported in 1933

Introduction Paragangliomas (PGLs) are slow-growing hypervascular tumors arising from neural crest cell derivatives throughout the body. PGLs are closely aligned with the distribution of the autonomic nervous system and preferentially arise in the

Introduction The last 15 years have brought significant advances in our understanding of the genetic basis of hereditary syndromes with a predisposition to pheochromocytoma (PC) and paraganglioma (PGL) (PCPGL) development. In the 1990s the genetic

Introduction Phaeochromocytomas (PHEO) of the adrenal gland and sympathetic paragangliomas (PGL) are catecholamine-producing tumours. Although 10–30% of these tumours metastasise, histopathological criteria that discriminate malignant from benign

Introduction The Cancer Genome Atlas (TCGA) proposed that neuroendocrine tumors of adrenal paraganglia, pheochromocytomas (PCCs) and extra-adrenal paraganglia paragangliomas (PGLs, together denoted PPGL) can be divided into three main

Introduction Pheochromocytomas (PHEOs) and paragangliomas (PGLs) are rare catecholamine-producing neuroendocrine tumors (NETs) arising in or outside the adrenal medulla, respectively ( Lenders et al . 2005 ). By definition, a PHEO is an intra

Introduction Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare neuroendocrine tumors of neural crest origin. Up to an estimated 60% of PCCs/PGLs are associated with germline or somatic mutations in one many susceptibility genes ( RET

Introduction Pheochromocytomas (PCs) are catecholamine-secreting tumours of chromaffin cells of the adrenal medulla and are closely related to paragangliomas (PGLs) which arise from sympathetic and parasympathetic chains ( Favier et al . 2005

Introduction Pheochromocytomas and paragangliomas are sympathetic neural-derived neoplasms. Over one third of these tumors carry germline mutations in one of the ten distinct genes ( Jafri & Maher 2012 ). Remarkably, somatic events in
