The damage to the follicles impairs ability to produce and secrete thyroid hormones which then leads to a hypothyroid phase. [1] [3] [4] [5] [7] As inflammation resolves, the thyroid follicles regenerate and begin to produce thyroid hormones once again. [3] In subacute granulomatous thyroiditis, there is infiltration of neutrophils and other ...
De Quervain's thyroiditis, also known as subacute granulomatous thyroiditis or giant cell thyroiditis, is a self-limiting inflammatory illness of the thyroid gland. [1] De Quervain thyroiditis is characterized by fever , flu-like symptoms , a painful goiter , and neck pain .
Hashimoto's Thyroiditis is a T-lymphocyte mediated attack on the thyroid gland. [15] T helper 1 cells trigger macrophages and cytotoxic lymphocytes to destroy thyroid follicular cells, while T helper 2 cells stimulate the excessive production of B cells and plasma cells which generate antibodies against the thyroid antigens, leading to ...
Hashitoxicosis, which can be abbreviated "Htx", [1] is a transient hyperthyroidism caused by inflammation associated with Hashimoto's thyroiditis disturbing the thyroid follicles, resulting in excess release of thyroid hormone. [2
Thyroiditis is generally caused by an immune system attack on the thyroid, resulting in inflammation and damage to the thyroid cells. This disease is often considered a malfunction of the immune system and can be associated with IgG4-related systemic disease, in which symptoms of autoimmune pancreatitis, retroperitoneal fibrosis and noninfectious aortitis also occur.
Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen .

Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
