A 44-year-old man presented with an enlarged painful lower anterior neck lump elevated serum concentrations of free thyroxine (T4) and tri-iodothyronine (T3), alongside the presence antithyroid peroxidase antibodies. Prior to presentation, patient was demonstrating recovery from a SARS-CoV-2 infection that required sedation, intubation, invasive ventilation in intensive care unit (ICU) for 11 d...

A patient presenting with subacute thyroiditis who had evidence of chlamydial infection is reported.

Figure 1. Intermediate-power microscopy shows the eosinophilic colloid-filled follicles at the periphery. In many follicles in the center, the epithelium has been replaced by the inflammatory reaction and the colloid is reduced or absent. Microabscess formation with foreign-body-type giant cells can be seen. Figure 2. A: The colloid is engulfed by the ring of foreign-body-type giant cells with ...

Whether with the passage of time subacute thyroiditis leads to hypothyroidism remains to be determined. Therefore, we evaluated the thyroid function including TRH test of 66 patients with a previous history of subacute thyroiditis and age-matched control subjects with special reference to the measurement of inorganic iodide. The patients were divided into 3 groups according to time lapse since ...

Thyroid imaging is nowadays an essential part of thyroid disease evaluation. Different types of thyroiditis may share some parallel clinical and biochemical features, what might lead to diagnostic difficulties, while thyroid imaging may aid in establishing proper diagnosis. In the lecture, usefulness of several imaging techniques (conventional ultrasonography, Doppler examination, sonoelastogra...

Granulomatosis with polyangiitis can be a complication of thyroid disease, not only autoimmune disease but also subacute thyroiditis.

Drug-induced hypersensitivity syndrome (DIHS) is a severe multiorgan system adverse drug reaction with reactivation of human herpesviruses (HHVs) such as HHV-6, HHV-7, cytomegalovirus (CMV) and Epstein-Barr virus. Various complications, including autoimmune diseases, sometimes appear during the course of DIHS. We report a case of salazosulfapyridine-induced DIHS associated with HHV-6 reactivati...

Although the etiology of Graves' disease is still not clear, it is generally suggested that environmental factors such as infections contribute to the development of Graves' disease. We report here three cases of Graves' disease which presented simultaneously with infectious mononucleosis due to primary EBV infection. Acute EBV infection might play an important role in the onset of Graves' dise...
