Thyroid nodules. Light micrograph of a section through a thyroid gland with colloid adenomas, or nodules (botom right and upper left)). The nodules are filled with colloid, a glycoprotein storage form of the thyroid hormones, and encapsulated in fibrous tissue (white). The nodules can lead to an enlargement of the thyroid gland and overproduction of thyroid hormone.
