title: Thymic small cell carcinoma associated with pulmonary squamous cell carcinoma.
abstract: A 63-year-old man presented with dyspnea on effort. Chest computed tomography showed an anterior mediastinal mass and a lung mass in the right lower lobe. Thallium scintigraphy revealed accumulation in the mediastinal mass. Therefore, under diagnosis of invasive thymoma or thymic carcinoma associated with suspected lung cancer, exploratory right thoracotomy was undertaken through a median sternotomy with video-assisted thoracoscopic support. The lung mass was intraoperatively diagnosed as squamous cell carcinoma. Right lower lobectomy and total thymectomy were then carried out without additional incision. Thymic small cell carcinoma was diagnosed; therefore the patient received 50 Gy of irradiation to the mediastinum. Ten months after surgery the patient is alive without recurrence.
