13.2 pathologic conditions of the endocrine system

disease caused by pituitary hypersecretion of growth hormone after completion of bone development, characterized by enlargement of bones of the front and rear feet and face

life-threatening condition of adrenal insufficiency characterized by severe weakness, low blood pressure, anorexia, digestive disturbance, bradycardia, and altered sodium-potassium balance

malignant, metastasizing tumors of adrenal cortex, which produce Cushing's syndrome

inflammation of adrenal glands

over-fuctioning of adrenal cortex

underfunctioning of adrenal cortex

lack or loss of appetite; symptom in some endocrine disorders

pituitary gland tumor whose cells stain with basic dyes

general ill health and malnutrition, which may be symptomatic of some endocrine disorders

benign tumor of pituitary gland, whose cells resist staining with dyes

pituitary basophilism, with excessive secretion of adrenocortical hormone, characterized by potbellied appearance, alopecia, increased thirst and urination, muscle wasting and thin skin (also called hyperadrenocorticism)

metabolic disorder characterized by polyuria and excessive thirst resulting from insufficient production of antidiuretic hormone (ADH)

metabolic disease caused by absolute or relative lack of insulin; signs include thirst and urination and sugar in urine (glucosuria)

enlargement of thyroid

hyperfunction of parathyroid gland of primary type resulting from neoplasms or unknown causes and secondary type because of metabolic disorder, producing calcium imbalance in bodily systems, with osteoporosis and deposition of calcium in tissues

overproduction of thyroid hormone, especially common in older cats

developmental disorder caused by inadequate secretion of pituitary gonadotropins, resulting in sexual immaturity and decreased functional activity of gonads in males and females.

insufficiency of parathyroid glands, which may be familial or because of excision, disease, or injury of thyroid or parathyroid glands, resulting in hypocalcemia, with increased bone density resulting from decreased bone resorption

underfunction of thyroid gland

muscular cramps and spasms, resulting from hypocalcemia because of excision or injury to parathyroids

excessive thirst; symptom of diabetes

excessive urnation; symptom of diabetes

seminoma, Sertoli's cell tumor (estrogen-secreting), and interstitial cell tumor (androgen secreting), usually benign tumors of testes; more common in cryptochid testicles

muscle spasm and cramp; symptom of hypoparathyroidism

benign tumor of thyroid gland; may occur in cats with hyperthyroidism

inflammation of thyroid gland

pertianing to stubstances destructive to to thyroid gland

any disease or disorder of thyroid gland
