hashimoto’s thyroiditis, the most common autoimmune thyroid disease, is due to destruction of the thyroid gland by autoantibodies. various types of thyroid malignancies may arise in hashimoto’s thyroiditis. follicular carcinomas, papillary carcinomas, lymphomas, medullary carcinomas and hurthle cell neoplasms may develop in hashimoto’s thyroiditis. we present a rare case report of a 35-year-old...

Our purpose in this paper is to make a case for the need to question whether Riedel's thyroiditis is in fact a rare variety of subacute thyroiditis. Total thyroidectomy was performed on a patient with a huge thyroid mass. The histopathological diagnosis was Riedel's thyroiditis with classical lymphoplasmacytic infiltration destroying thyroid tissue and invading perithyroidal soft tissue. Howeve...

autoimmune thyroid diseases (atd) are multifactorial conditions that result from genetic predisposition in combination with environmental risk factors. helicobacter pylori infection as an environmental risk factor has been proposed to imitate the antigenic components of the thyroid cell membrane and may play a leading role in the onset of the autoimmune diseases, such as hashimoto thyroiditis. ...

Background:  Hashimotochr('39')s thyroiditis can be present with a localized palpable nodule though presentation as a hyperfunction "nodule" is extremely rare.  The first case of Hashimotochr('39')s thyroiditis and hot nodule was reported in 1971 by warner. Case Presentation: We reported a 26-year-old hypothyroid woman in Hashimotochr('39')s thyroiditis background with a hyperactive thyroid no...

We have reviewed 1066 thyroid lesions and compared the relative incidence of the so called 'palpation thyroiditis' between autoimmune thyroiditis and normal thyroid parenchyme surrounding the nodular thyroid lesion and also discussed the pathogenesis of palpation thyroiditis. The typical histopathologic features of 'palpation thyroiditis' were seen in 275 cases among 467 adenomatous goiters and...

Riedel's thyroiditis is a rare form of infiltrative and inflammatory disease of the thyroid gland and can be associated with systemic fibrotic processes, Hashimoto thyroiditis and Graves disease. Riedel thyroiditis in combination with Graves disease however, is very rare. A 57-year-old woman with a past medical history significant for Graves disease diagnosed 30 years ago presented with an enla...

BACKGROUND It is controversial whether autoimmune thyroiditis is associated with higher frequency of papillary thyroid carcinoma (PTC). METHODS This was a cross-sectional, retrospective study. PTCs were compared to benign nodules regarding the prevalence of autoimmune thyroiditis over 16 years. RESULTS A similar proportion of autoimmune thyroiditis was observed in both benign and/or maligna...

BACKGROUND It has been recently accepted that IgG4-related thyroiditis is comparable to the Hashimoto and Riedel thyroiditis and Graves disease which are rich in IgG4-secreting plasma cells. Many physicians believe that in IgG4-related thyroiditis, the thyroid is entirely enlarged and diffusely affected, which is similar to conventional thyroiditis, but rarely ever accompanied by pseudoneoplast...

The aim of the study was to determine the incidence of coexistence of papillary carcinoma and Hashimoto's thyroiditis in cytologic material. Cytologic findings were collected from 10508 patients that underwent ultrasound-guided fine needle aspiration cytology (FNAC) of the thyroid. Hashimoto's thyroiditis was found in 2156 (20.5%) and papillary carcinoma in 269 (2.6%) of 10508 patients with FNA...

Recent reports on Hashimoto's thyroiditis (HT) with increased numbers of IgG4-positive plasma cells suggest that this type of HT may have a close relationship to IgG4-related disease (IgG4-RD). This unique subgroup of HT is termed as IgG4 thyroiditis and reveals distinct clinical, serological, and sonographic features from the non-IgG4 thyroiditis group. On the basis of immunostaining for IgG...
