Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Melson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat extreme slackness. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Some of the possible causes of a tumor in a dog's mouth or on the jaw include the following: ... If the margins of the tumor are free of cancer cells after surgery, it can even be cured (2 ...
Rarely a cat may have double adenomas. In a few cases the diagnosis has been pituitary acidophilic hyperplasia. In dogs nearly all cases of acromegaly are caused by endogenous or exogenous progestogens, this causes a hypersecretion of growth hormones from the mammary gland. Pituitary tumours causing excess growth hormone secretion are very rare ...
Transsphenoidal surgery (removal of the tumor by an operation through the nose and the sphenoidal sinuses) may, apart from addressing symptoms related to the tumor, also improve pituitary function, although the gland is sometimes damaged further as a result of the surgery. When the tumor is removed by craniotomy (opening the skull), recovery is ...
A 10-year-old female beagle with oral cancer. Cancer is the leading cause of death in dogs. [1] It is estimated that 1 in 3 domestic dogs will develop cancer, which is the same incidence of cancer among humans. [2] Dogs can develop a variety of cancers and most are very similar to those found in humans.
The usual causes are genetic, often related to autoimmune disorders, where the body attacks and kill its own tissue ("immune mediated destruction"). [8] Other cases are caused by various disease processes, [8] [9] [10] including failure of the pituitary gland to secrete ACTH, the hormone which stimulates the adrenal production of cortisol. [5]
Despite similar symptoms and blood test results to Cushing's disease, evaluation of dogs with SARDS did not reveal any tumors in the pituitary or adrenal glands, [9] and recent work has indicated significant differences in the clinical and laboratory test parameters between the two diseases. [10]
