Subacute Thyroiditis Following Third Dose of Pfizer-BioNTech COVID-19 (mRNA) Vaccine in a Patient with Clear Cell Renal Cell Carcinoma: A Case Report
Year: 2023
Type: article
Study design: Case Report
Abstract: Over 160 cases of subacute thyroiditis (SAT) following COVID-19 vaccination or infection have been reported in the literature. Roughly one-half were attributed to either the first or second dose of the COVID-19 vaccine. We report a rare case of SAT in a 47-year-old male patient with a history of clear cell renal cell carcinoma and advanced chronic kidney disease, among other comorbidities, excluding thyroid disease. After he received the third dose of the Pfizer mRNA vaccine, a deranged thyroid profile was accidentally discovered. His SAT remained asymptomatic and normalized in about six months without treatment. SAT post-COVID vaccination is a self-limiting and rare condition that should be considered in the differential diagnosis of silent thyroiditis.
