| Résumé: | Graves’ disease is an autoimmune condition leading to the activation of and an increase in thyroid hormone secretion. Manifestations of hyperthyroidism in Graves’ disease can vary among people. In this case, we report a 24-year-old Thai man with a rare presentation of unilateral gynecomastia along with symptoms of thyrotoxicosis. Physical examination revealed a 3 cm non-tender palpable glandular tissue beneath and around the left areola without nipple discharge and moderately diffuse thyroid enlargement with thyroid bruit. Thyroid function test showed a typical thyrotoxicosis state with elevated serum-free T4 and decreased serum TSH. His diagnosis of Graves’ disease was confirmed biochemically with a highly elevated anti-TSH receptor antibody. Early treatment with anti-thyroid medication was given first, followed by Radioiodine treatment (RAI) for definitive treatment due to high level of anti-TSH receptor antibody, enlarged thyroid and severe thyrotoxicosis presentation at a young age, which might not resolve by anti-thyroid medication alone. The patient responded well to treatment and achieved complete resolution of unilateral gynecomastia with clinically and biochemically euthyroid within 3 months after treatment. No recurrent gynecomastia was found during the 2-year follow-up. |
