• 

  This is a gross photograph of thyroid gland taken at autopsy. The gland is only slightly enlarged and has a firm texture.

• 

  This is a low-power photomicrograph of thyroid from this case. Note that the tissue is more cellular than one would expect and there does not appear to be normal colloid-filled blue spaces in this gland.

• 

  This is a higher-power photomicrograph of thyroid from this case. Note the large number of blue-staining inflammatory cells in this tissue. These cells appear to be forming germinal centers. Some residual thyroid gland tissue can be seen in this section (arrows).

• 

  This is another view of thyroid gland filled with inflammatory cells forming germinal centers (arrows).

• 

  This is a higher-power photomicrograph of thyroid from this case showing the inflammatory cells and the residual thyroid tissue.

• 

  This is another higher-power photomicrograph of thyroid from this case showing the inflammatory cells and the residual thyroid tissue.

• 

  This is a high-power photomicrograph showing the inflammatory cells infiltrating into the residual thyroid tissue (arrows).

• 

  This is a high-power photomicrograph showing the lymphocytes and plasma cells surrounding the thyroid gland epithelium.

• 

  This high-power photomicrograph shows more clearly the lymphocytes and plasma cells surrounding the thyroid gland epithelium. Large, eosinophilic, degenerating thyroid gland cells (Hurthle cells) can be seen in this section (arrows).
