A 65-year-old female was admitted to our hospital for an anterior mediastinal tumor. A CT scan revealed an anterior mediastinal tumor and a solitary nodule in the left lower lobe. (superior segment: S6). The patient requested only resection of the anterior mediastinal tumor; therefore, extended thymectomy with partial resection of the right upper lobe was performed. The histological diagnosis of the anterior mediastinal tumor was thymic squamous cell carcinoma. After two-years postoperative follow-up, CT scan revealed a growing solitary nodule in the lower lobe (S6). A left lower lobectomy for the lung tumor was performed as a second operation, and the histological diagnosis was primary lung adenocarcinoma. Six months after the second surgery, the patient is alive without recurrence. Cases of synchronous thymic carcinoma and primary lung cancer are rare; hence, we report this case.
