A phaeochromocytoma (PCC) is a rare tumour that secretes catecholamines. It is derived from chromaffin cells, usually in the adrenal medulla; however, occasionally extra-adrenal phaeochromocytomas or paragangliomas (PGLs) occur.1 Many - but not all - authors define phaeochromocytoma as coming from the adrenal medulla and if the tumour is similar but located elsewhere, it is called a paraganglioma.
