If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more

Can you tell me about rare adrenal gland tumor?

Can you tell me about rare adrenal gland tumor?

3 types: The adrenal gland is a double structured gland with a central medullary portion which when a tumor develops produces adrenaline like products elevating BP. The cortical tumors produce cortisone and when functional present with Cushngs syndrome. The 3rd lesion is metastatic to adrenal from primaries of kidney and lung and sometimes melanoma. ...Read more
