title: Thyroid cancer with a cystic mediastinal tumor invading the right main bronchus.
abstract: A 55-year-old woman presented with hemosputum. She had noted thyroid swelling and computed tomography was performed by her family physician. The computed tomographic scan revealed a thyroid tumor and a mediastinal cyst connecting to the thyroid tumor. Fiberoptic bronchoscopy showed direct invasion to the right main bronchus. She was preoperatively diagnosed with thyroid cancer combined with a mediastinal tumor and underwent a thyroidectomy and mediastinal tumor resection. These tumors were adherent to the esophagus, trachea, superior vena cava, and azygos vein; however, the mediastinal cyst, despite the fact that it directly invaded the right main bronchus, showed no malignant cells.
