== Clinical Summary ==
This 18-year-old girl presented with complaints of swelling in the neck, weight loss, bulging of the eyes, tremor, decreased heat tolerance, loose stools, and occasional palpitations. Physical examination revealed normal blood pressure, resting tachycardia of 110 beats per minute, mild exophthalmos, eyelid lag, and a diffusely enlarged thyroid gland. Pertinent laboratory findings were thyroxine (T4) level 30.8 mcg/dL, free thyroxine was 2.7 ng/dL, and thyroid stimulating hormone (TSH) was 0.22 mcIU/mL. She was given propylthiouracil until she became nearly euthyroid, at which time a thyroidectomy was done. == Autopsy Findings ==The thyroid gland weighed 45 grams. It was beefy red in color and had a homogeneous fleshy consistency.

File:IPLab6GravesDisease2.jpg|This is a low-power photomicrograph of thyroid tissue from this case. The tissue is very cellular with very little colloid.
File:IPLab6GravesDisease3IPLab6GravesDisease3x.jpg|This is a higher-power photomicrograph of thyroid. The tissue is very cellular and there is little much less colloid(C) filling the glands than is normally seen.
File:IPLab6GravesDisease4.jpg|This is a high-power photomicrograph of thyroid. Note the cellularity of the tissue with marked infolding of the epithelial tissue.
File:IPLab6GravesDisease5IPLab6GravesDisease5x.jpg|This is a high-power photomicrograph of thyroid. Note the papillary projections and the moth“scalloped” or “moth-eaten eaten” appearance (arrows) of the colloid(C). This appearance indicates active absorption of the colloid to form thyroglobulin.

== Study Questions ==
* It is more common in patients with other forms of autoimmune thyroid problems (e.g., Hashimoto's thyroiditis)</spoiler>
* <spoiler text="Does Graves' disease predispose to thyroid cancer?">There is little evidence to suggest an increased frequency of thyroid cancer in patients with Graves' disease.</spoiler>
