Pretibial myxedema observed on physical examination is most consistent with which condition?

Explanation:
Pretibial myxedema reflects autoimmune activity linked to Graves disease, the most common cause of hyperthyroidism. In Graves, antibodies stimulate fibroblasts in the skin to produce excess glycosaminoglycans (mucin), leading to thickened, non-pitting edema and indurated plaques on the shins. This skin change is characteristic of hyperthyroidism due to Graves and is not typical of hypothyroidism, Cushing's syndrome, or lymphedema. So, pretibial myxedema is most consistent with hyperthyroidism.
