Endemic goitre by significant compression of nearby structures. Endemic goitre Endemic goiter is a type of goitre that is associated with dietary iodine deficiency. Some inland areas where soil and water lacks in iodine compounds and consumption of marine foods is low are known for higher incidence of goitre. In such areas goitre is said to be "endemic". This type of goiter is easily preventable. In most developed countries regulations have been put into force by health policy institutions requiring salt, flour or water to be fortified with iodine.

Toxic multinodular goitre specific entity in each patient/case is not always clear retrospectively, especially in older literature.

Toxic multinodular goitre Toxic multinodular goiter (also known as toxic nodular goiter, or Plummer's disease) is an active multinodular goiter associated with hyperthyroidism. It is a common cause of hyperthyroidism in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which
