Myxedema (British English: myxoedema) is a term used synonymously with severe hypothyroidism, but also to describe a dermatological change that can occur in hypothyroidism and (rare) paradoxical cases of hyperthyroidism. In this latter sense, myxedema refers to deposition of glycosaminoglycans in the dermis, which results in swelling of the affected area.
