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

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).
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).
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.
This is a photomicrograph of the adenoma. Note that the follicular architecture is well developed throughout this section.

Related IPLab Cases[edit]
Pulmonary emphysema is a condition in which the air spaces distal to the terminal bronchioles are permanently increased in size due to either destruction of the wall or alveolar dilatation.
Nodular hyperplasia of the prostate--characterized by large discrete prostatic nodules--is a common disorder in men over 50 years of age. The nodules cause the prostate to be enlarged and to have an increased weight. The human prostate is surrounded by a restrictive capsule. These nodules cause increased pressure within the capsule which leads to constriction of the urethra as it passes through the prostate. Urethral constriction leads to retention of urine.
