This 80-year-old white female's death came as the result of cardiopulmonary disease -- hypertension, coronary artery disease, pulmonary emphysema and cardiac hypertrophy.

~~== Autopsy Findings ==~~

During a routine postmortem examination, this patient's thyroid gland was found to be nodular. The right lobe contained several colloid nodules. Located in the left lobe was a 2-cm well-circumscribed mass.

File:~~IPLab7Adenoma1~~.jpg|This is a low-power photomicrograph of a nodule found in the thyroid of this case. Note that the mass is well-circumscribed and there is a sharp line of demarcation between the mass and the adjacent thyroid tissue (arrows).

File:IPLab7Adenoma1b.jpg|This is a low-power photomicrograph of a nodule found in the thyroid of this case. Note that the mass is well-circumscribed and there is a sharp line of demarcation between the mass and the adjacent thyroid tissue (arrows).

File:~~IPLab7Adenoma2~~.jpg|This is a higher-power view of the border between the tumor mass and the adjacent thyroid tissue. Note that the mass has ~~compressed the adjacent normal thyroid tissue~~ (arrow). Also note the different morphology between the adenoma (very cellular, dense follicles~~, little or no colloid~~) and the adjacent normal thyroid (larger follicles, colloid).

File:IPLab7Adenoma2b.jpg|This is a higher-power view of the border between the tumor mass and the adjacent thyroid tissue. Note that the mass has a capsule (arrow). Also note the different morphology between the adenoma on the bottom (very cellular, dense follicles) and the adjacent normal thyroid (larger follicles, colloid).

File:~~IPLab7Adenoma3~~.jpg|This is another higher-power photomicrograph of the adenoma (~~left~~) and the adjacent thyroid tissue (~~right~~). Note the ~~compression of the adjacent normal thyroid and the difference in morphology between the adenoma and the thyroid.~~

File:IPLab7Adenoma3b.jpg|This is another higher-power photomicrograph of the adenoma (bottom) and the adjacent thyroid tissue (top). Note the capsule(*) separating the adenoma from the adjacent normal thyroid tissue.

~~File:IPLab7Adenoma4.jpg|This photomicrograph demonstrates the densely packed follicular pattern in the adenoma~~ (~~left~~) ~~and~~ the ~~larger colloid-filled follicles of~~ the normal thyroid ~~(right). An area of compressed thyroid is present adjacent to the adenoma (arrows)~~.

File:IPLab7Adenoma4b.jpg|This is a photomicrograph of the adenoma. Note that the follicular architecture is well developed throughout this section.

File:~~IPLab7Adenoma5~~.jpg|This is a photomicrograph of an adenoma. Note that the follicular architecture is well developed ~~and more or less uniform~~ throughout this section.

~~File:IPLab7Adenoma6.jpg|This high-power photomicrograph demonstrates the relatively normal cellular morphology of this follicular adenoma~~.
