摘要:The aim of this study is to review and discuss the clinical features and treatment options for the Marine-Lenhart syndrome, an uncommon thyroid disturb. The methodology adopted was a bibliographic research. The results of this study show that different mechanisms are implicated in the pathogenesis of Graves’ disease and in the nodular formation of thyroid tissue with functional autonomy. Graves’ disease is caused by an autoimmune process that involves the entire thyroid gland and is characterized by the presence of TSH receptor stimulating antibodies. The present study concludes that caution should be exercised in interpreting thyroid disease in Graves’ disease. The treatment of thyrotoxicosis requires high doses of oral drugs. Relapsing antithyroid therapy occurs soon after oral antithyroid therapy is discontinued. This presentation should alert the physician about the existence of toxic nodules, and about the possibility of a Marine-Lenhart Syndrome..
