Abstract
A 50-year-old man was referred to us due to palpitation, sweating, and body weight loss.
He had an enlarged thyroid with hyperthyroidism and was positive for anti-TSH receptor antibody, leading to diagnosis of Gravesʼ disease. He also showed an enlarged parotid, and
cytology revealed myoepithelial cells with interstitial mucus, which was diagnostic for pleomorphic parotid adenoma.
