Colloid nodules are non-neoplastic benign nodules occurring within the thyroid gland. They form the vast majority of nodular thyroid disease.
Pathology
Colloid nodules are composed of irregularly enlarged follicles containing abundant colloid. A colloid nodule may be single or multiple and can vary considerably in size.
Some colloid nodules can be cystic (cystic colloid nodule) and may contain areas of necrosis, hemorrhage and/or calcification.
Calcification may represent prior multinodular goiter hemorrhage.
