A disorder marked by progressive enlargement of the head, face, hands, feet, and chest due to excessive secretion of growth hormone by the anterior lobe of the pituitary gland. Also called Marie's disease.

Acromegaly

A rare disease resulting from excessive growth hormone caused by a benign tumor. If such a tumor develops within the first 10 years of life, the result is gigantism (in which growth is accelerated) and not acromegaly. Symptoms include coarsening of the facial features, enlargement of the hands, feet, ears, and nose, jutting of the jaw, and a long face.

acromegaly

[ak′rəmeg′əlē]

Etymology: Gk, akron + megas, great

a chronic metabolic condition in adults caused by oversecretion of growth hormones by the pituitary gland. It is characterized by gradual, marked soft tissue enlargement and widening and thickening of skeletal bones in the face, jaw, hands, and feet. Hypertrophy of the vocal cords leads to deepening of the voice. Complications from increased growth hormone levels include atherosclerosis, peripheral neuropathy, hypertension, hyperglycemia, airway obstruction, cardiomyopathy, and visceromegaly involving the salivary glands, liver, spleen, and kidneys. Treatment normally includes radiation, pharmacologic agents, or surgery, often involving partial resection of the pituitary gland. Also called acromegalia. Compare gigantism. acromegalic, adj.

n chronic metabolic disorder of middle-aged and older individuals, in which excessive growth hormone secretion results in the progressive thickening and enlargement of the facial bones and jaw. Also called
acromeglia.

acromegaly (akrmeg´lē),

n (Marie's disease), a condition caused by hyperfunction of the pituitary gland in adults. Characterized by enlargement of the skeletal extremities, including the feet, hands, mandible, and nose.

Acromegaly.

acromegaly

abnormal enlargement of the extremities of the skeleton due to overgrowth of connective tissue and increased appositional growth of bone caused by hypersecretion of growth hormone (GH) from the pituitary gland in adults. The condition has been reported in cats and dogs. Called also hypersomatotropism.

iatrogenic acromegaly

may be caused by the administration of drugs that stimulate growth hormone-secreting acidophils. Progestational agents, usually administered for estrus control, have been responsible for this disorder in dogs. Affected dogs show coarsening of facial features, widening of interdental spaces, enlargement of the abdomen, thickening of skin with excessive hair growth, and inspiratory stridor.

acromegaly

Endocrinology A disease of adults due to excess hGH secretion of anterior pituitary or extrapituitary origin, or due to excess secretion of GH-RH by hypothalamic tumors or ectopic hGH production by small cell carcinoma of the lungs, carcinoids, islet cell tumors, adrenal adenomas or other 'endocrine' tumors Clinical Coarsened, enlarged facies, lips, nose, jaw, hands, feet, and frontal bones, widely spaced teeth, bone proliferation in extremities, soft tissue thickening, hyperhidrosis, macroglossia, headache, amenorrhea, impotence, somnolence, moodiness, glucose intolerance, HTN, heart disease, carpal tunnel syndrome, sleep apnea.
