Overview
The exact pathogenesis of Riedel's thyroiditis is not fully understood. The presence of thyroid autoantibodies and lymphoid infiltration of the thyroid gland resembling that of Hashimoto's thyroiditis might indicate an autoimmune etiology. It is considered that the infiltrating lymphocytes release cytokines which are responsible for the activation of fibroblasts responsible for the fibrosis.[1] Riedel's thyroiditis is characterized by a replacement of the normal thyroid parenchyma by a dense fibrosis that invades adjacent structures of the neck and extends beyond the thyroid capsule.[2] This makes the thyroid gland stone-hard and fixed to adjacent structures. A shared mechanism with retroperitoneal fibrosis and sclerosing cholangitis has been suggested.[3]
Pathophysiology
Pathogenesis
- The exact pathogenesis of Riedel's thyroiditis is not fully understood. The presence of thyroid autoantibodies and lymphoid infiltration of the thyroid gland resembling that of Hashimoto's thyroiditis might indicate an autoimmune etiology.
- It is considered that the infiltrating lymphocytes release cytokines which are responsible for the activation of fibroblasts responsible for the fibrosis.[1]
- Riedel's thyroiditis is characterized by a replacement of the normal thyroid parenchyma by a dense fibrosis that invades adjacent structures of the neck and extends beyond the thyroid capsule.This makes the thyroid gland stone-hard and fixed to adjacent structures.[2]
- A shared mechanism with retroperitoneal fibrosis and sclerosing cholangitis is also suggested.[3]
Genetics
- [Disease name] is transmitted in [mode of genetic transmission] pattern.
- Genes involved in the pathogenesis of [disease name] include [gene1], [gene2], and [gene3].
- The development of [disease name] is the result of multiple genetic mutations.
Associated Conditions
Riedel's thyroiditis is associated various other autoimmune conditions including:[1][4][5][6]
- Graves’ disease
- Hashimoto’s thyroiditis
- Addison’s disease
- Pernicious anemia
- Type 1 diabetes
Microscopic Pathology
- On microscopic histopathological analysis, destruction of thyroid follicle by inflammatory cells and fibrous tissues and invasion of surrounding structures are characteristic findings of Riedel's thyroiditis.The inflammatory cells including lymphocytes, plasma cells and eosinophils are present in a dense matrix of hyalinized connective tissue.[7][8]
