This is a photograph of the thyroid from this case. Note that the gland is enlarged and is dark red.
This is a low-power photomicrograph of thyroid tissue from this case. The tissue is very cellular with very little colloid.
This is a higher-power photomicrograph of thyroid. The tissue is very cellular and there is little colloid.
This is a high-power photomicrograph of thyroid. Note the cellularity of the tissue with marked infolding of the epithelial tissue.
This is a high-power photomicrograph of thyroid. Note the papillary projections and the moth-eaten appearance of the colloid. This appearance indicates active absorption of the colloid to form thyroglobulin.
This is a gross photograph of a thyroid from a case of nodular goiter.
Closer view of cut surface of the thyroid with nodular goiter. Note the multilobular appearance of the tissue.
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.
