“The pituitary gland is located near the center and bottom of the brain. It produces a number of critical hormones that control many parts of the body, including several other endocrine glands. For this reason, it is sometimes called a “master gland.” Because large numbers of hormones are produced by the pituitary, a variety of different conditions can be caused by pituitary disease or tumors.

“Affected horses often have a history of impaired or delayed healing of wounds, which is a result of immune suppression associated with the disease.”
