Colloid nodules (CN's) are ~~non~~ 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. Some colloid nodules can be cystic (cystic colloid nodule), and may contain areas of necrosis, haemorrhage and/or calcification. Colloid nodule may be single or multiple and can ~~vary considerably~~ vary considerably in size.
