chro·maf·fin cell

a cell that stains with chromic salts; found in adrenal medulla and paraganglia of the sympathetic nervous system.

chro·maf·fin cell

(krō-maf'in sel)
A cell that stains with chromic salts in medulla of the suprarenal gland and paraganglia of the sympathetic nervous system.

chromaffin cell

A cell that produces, stores, and secretes catecholamines (dopamine and norepinephrine). Chromaffin cells are found in the medulla of the adrenal glands and in small clusters in the sympathetic ganglia.

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.
