Circumscribed myxedema is a form of myxomatous degeneration associated with dysfunction of the thyroid gland. Whereas the edema of true myxedema, in the medical sense, is not usually evident until the basal metabolic rate has dropped to — 18 or —20 per cent, the objective changes of circumscribed myxedema may make their appearance concomitant with the degree of elevation of the basal metabolic rate usually associated with a severe grade of hyperthyroidism.
