These cell stain yellow brown with the chrome salts and hence are called chromaffin cells.
There is evidence to suggest that the plasticity of chromaffin cells declines during development, which may overlap or be the same as early stages of ageing |17, 18~.
In this syndrome, patients develop polycythemia at a later age relative to HIF2A mutation carriers, but they appear to have a similar high risk of recurrent chromaffin cell tumors, especially PGL [17, 53].

The columnar or polyhedral chromaffin cells of the adrenal medulla of the African giant rat which form clusters and anastomosing cords separated by sinusoids had also been reported in mammals (Bacha & Bacha).
Mediastinal paragangliomas are extra adrenal chromaffin cell tumours that account for fewer than 10% of all mediastinal neuroendocrine tumours.2 They represent only 2% of all catecholamine secreting tumours of the body and 0.3% of all mediastinal tumours.2 Paragangliomas maybe functional, if they synthesize and secrete catecholamines or non functional, if they synthesize but donot secrete catecholamines.3

Pheochromocytomas and paragangliomas (PPGLs) [3] are neuroendocrine tumors arising from adrenal and extraadrenal chromaffin cells, respectively (1).
Catecholamine-producing tumors are neuroendocrine tumors that affect the chromaffin cells of adrenal medulla and postganglionic fibers of the sympathetic nervous system.
A phaeochromocytoma is a rare neuro-endocrine tumour of the paraganglionic chromaffin cells affecting 2-8 persons per million per year.[1-6] Although usually benign, around 10% are found to be malignant.[1,2,7] They can arise in the adrenal medulla and also, in around 10% of cases, in the extra-adrenal paraganglionic cells.[1,3-5] These extra-adrenal tumours are known as paragangliomas.
