Overview

The histological analysis in Hashimoto's thyroiditis may show inflammatory cell infiltration and hurthle cells.

Other Diagnostic Studies

Gross Pathology

• The gland is usually diffusely enlarged, firm, and slightly lobular. The capsule is intact, and the cut surface is light-tan and has a slight lobular pattern.
• At autopsy, significant subarachnoid hemorrhage from the ruptured berry aneurysm was documented. In addition, the thyroid gland was mildly enlarged and firm. On cut section, the tissue was slightly pale.

Microscopic Pathology

Microscopically there is massive infiltration of the thyroid gland by lymphocytes and plasma cells. Germinal centers can often be seen in the gland. Thyroid follicles are usually absent and the few remaining follicles are devoid of colloid.

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).
