Polychromasia (also known as Polychromatophilia) is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation.(Poly- refers to many, and -chromasia means color.) These cells are often shades of grayish blue.
Background. A pheochromocytoma is a rare, catecholamine-secreting tumor derived from chromaffin cells. The term pheochromocytoma (in Greek, phios means dusky, chroma means color, and cytoma means tumor) refers to the color the tumor cells acquire when stained with chromium salts.ecause of excessive catecholamine secretion, pheochromocytomas may precipitate life-threatening hypertension or cardiac arrhythmias. If the diagnosis of a pheochromocytoma is overlooked, the consequences can be disastrous, even fatal; however, if a pheochromocytoma is found, it is potentially curable.
