Chromaffin tissue tumour,

The molar proportion of catecholamines to adenosine triphosphate in the medulla of the normal human suprarenal gland is about 1 4-5, whereas in tissue from a phaeochromocytoma a proportion of 1 10-35 was found. This observation, coupled with that of decreased granular storage of catecholamines in the cells of a phaeochromocytoma, point to a disturbance in the storage mechanisms of cells from chromaffine tissue tumours. (989,1469) increased secretion from such tumours is probably connected with this disturbance. [Pg.22]

A well encapsulated, lobular, vascular tumour of chromaffin tissue of the adrenal medulla or sympathetic paraganglia. [Pg.403]

The phaeochromocytoma and the paraganglioma are tumours of the chromaffine tissue (chromaffinomata). The former originates from the suprarenal medulla, the latter from chromaffine cells which are outside the suprarenal gland. The local distribution of these tumours is summarized in Table which is based on observations in 204 patients with a... [Pg.92]
