So far its numerous side effects have been reported in the literature. It may be difficult to always put IFN-induced thyroid diseases into a single classic thyroid disease table. There are numerous atypical thyroid diseases due to IFN usage for hepatitis C virus. Herein, we present a case with a rare clinical table such as thyrotoxicosis observed following IFN-α therapy in a patient with euthyroid nodular thyroid without autoimmune thyroiditis findings and the use of therapeutic apheresis method for the treatment of disease.
