ABSTRACT
Subacute thyroiditis generally presents with pain in the thyroid region, fever, thyrotoxicosis and elevated markers of acute inflammation. On the other hand, Hashimoto’s thyroiditis is most frequently diagnosed in the hypothyroid phase with positive antithyroid autoantibodies. Here, we describe the case of a patient who presented with clinical features of subacute thyroiditis but laboratory and pathological features compatible with Hashimoto’s thyroiditis. The patient was finally diagnosed with painful Hashimoto’s thyroiditis.
