Autoimmune thyroiditis may appear as thyrotoxicosis,1.2 but it usually leads to hypothyroidism, although that evolution may take years.3-6 We describe a 14½-year-old girl whose condition was in the thyrotoxic phase, who required antithyroid drugs, and who became hypothyroid in three months. The shortest interval previously described was six months.5

Report of a Case.—This 14½-year-old girl was admitted to the hospital with complaints of malaise, weight loss, sore neck, and mild fever of one week's duration, preceded by cough and rhinitis. Three days prior to admission, tender swelling was noted in the anterior side of the neck. On admission, she had a temperature of 38.9 °C, a pulse rate of 120 beats per minute and a blood pressure of 120/80 mm Hg. Her skin was warm and moist. The thyroid gland was threefold enlarged, soft and rubbery in consistency, and nontender, without local inflammatory signs. No
