This is another view of thyroid gland filled with inflammatory cells forming germinal centers (arrows).
File:IPLab6Hashimoto3.jpg
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 sectio...
File:IPLab6Hashimoto2.jpg
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.
File:IPLab6Hashimoto1.jpg
This is a gross photograph of thyroid gland taken at autopsy. The gland is only slightly enlarged and has a firm texture.
