A 55-year-old man was admitted to our hospital with a complaint of slight left chest pain and dyspnea on effort of 2 months duration. He had had Basedow's disease, which had been treated with high-dose (300 mg daily) propylthiouracil (PTU) for 15 years. Chest X-ray on admission showed left moderate pleural effusion, and thoracentesis revealed eosinophilic pleural effusion (EPE). After normalization of the thyroid hormone and the anti-TSH receptor antibody had been confirmed, PTU was decreased gradually and discontinued. Since then, pleural effusion has disappeared without recurrence. We conclude that in this case, EPE was induced by a long-term use of PTU.
