Thymic carcinoma incidentally detected on routine chest computed tomography; report of a case

摘要

We reported a case of thymic carcinoma. A 61-year-old man was admitted to evaluate an abnormal shadow of lung field by chest X-ray. Routine chest computed tomography (CT) showed no abnormal findings on the lung field, but thymic tumor was incidentally detected. We suspected thymoma, performed a mediansternotomy and thymectomy with partial resection of pericardium. Pathological findings diagnosed undifferentiated carcinoma (large cell type) of thymus, the patient underwent radiation therapy of the mediastinum at a total dosage of 50 Gy and chemotherapy [cisplatin (CDDP) + vinorelbine ditartrate + mitomycin C (MMC)]. He has been doing well without recurrence for 2 years after the operation.
