De Quervain’s thyroiditis or subacute granulomatous thyroiditis is a rare inflammatory condition triggered by a viral infection that occurred 2–6 weeks earlier.1,2 Many viruses have been implicated in the development of thyroiditis, but prior to the current pandemic coronavirus infection has never been associated with clinical subacute thyroiditis.3 Single-cell RNA profiling of the angiotensin converting enzyme 2 receptor (SARS-CoV-2 receptor), has proposed multiple tissue cells as the potential targets of SARS-CoV-2.4 Subsequent analysis across 36 tissues revealed a rank list of candidate cells potentially vulnerable to SARS-CoV-2. The top targets are lung cells and macrophages, cardiomyocytes, adrenal gland stromal cells and lastly stromal cells in testis, ovary and thyroid.5 Thyroiditis following COVID-19 may be under-recognized and the complications overlooked if thyrotoxicosis is not considered.
