The Thionamide Paradox: Thyrotoxicosis With Neutropenia as Initial Presentation of Grave’s Disease

摘要

Hyperthyroidism typically presents with symptoms such as tremors, palpitations, weight loss, heat intolerance and anxiety. Although rare, anemia, leukopenia or thrombocytopenia may develop as an unusual manifestation of thyrotoxicosis. Hematologic derangements have been reported as a side effect of antithyroid drugs (ATD) as well, and while ATD associated agranulocytosis is uncommon, it is a life-threatening condition.
