Toxic adenoma; Toxic multinodular goiter; Plummer's disease

Toxic nodular goiter arises from a long-standing simple goiter and occurs most often in the elderly. Symptoms are those of hyperthyroidism, but the protruding eyeballs seen in Graves' disease do not occur. Risk factors include being female and over 60 years old. This disorder is never seen in children.
