It is known that the risk of developing thyroid carcinoma is increased in patients with Graves’ disease (GD). Some reports document how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination or infection could represent new external triggers for autoimmune thyroid disease such as GD in patients with individual predisposition. We describe GD and Graves’ ophthalmopathy (GO) in a 27-year-old male patient 15 days after inactivated coronavirus disease 2019 (COVID-19) vaccine. Given the ophthalmopathy and uncontrolled hyperthyroidism, a thyroidectomy decision was made. Histopathological examination revealed a diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC), and GD was detected in the parenchyma of non-neoplastic thyroid tissue. Various environmental, genetic, and epigenetic factors that initiate the development of GD are known, and cases of GD after COVID-19 vaccination have also been reported. However, the etiology of GD after COVID-19 vaccination has not been fully elucidated in the literature. In addition, the DSV-PTC is a rare subtype of papillary thyroid carcinoma, and its association with GD has been reported in very few cases. Interestingly, we report for the first time a case of DSV-PTC associated with GD histopathologically following inactivated COVID-19 vaccine. The molecular mechanisms of extremely rare co-existence in our case have aroused curiosity and need to be clarified by further studies.
