Abstract
An 80-year-old male was found to have an anterior mediastinal tumor and a lung tumor of the left lower lobe. After a 5- month follow-up, a CT scan showed a growing anterior mediasitinal tumor and a solitary nodule in the left lower lobe. Extended thymectomy with partial resection of the right upper lobe and partial pericardiectomy were performed via a median sternotomy. During this procedure, a left lower lobectomy was performed by left 5th intercostal thoracotomy. Pathological examination revealed the coexistence of squamous cell carcinoma of the thymus and an atypical carcinoid of the lung. Synchronous thymic carcinoma and lung carcinoid are rare.
