A 76-year-old man was referred to our division because of an abnormal shadow on chest computed tomography (CT). CT revealed a 20 mm nodule in the anterior mediastinum. Non-ivasive thymoma was suspected and thymomectomy and resection of right thymus was performed.

The resected tumor was 25×25×13 mm in size. Pathologically the tumor was composed with polygonal cell components and spindle cell components, partially invading surrounding tissue. Cytokeratin AE1/3 and epithelial membrane antigen (EMA) were strongly positive, and the pathological diagnosis was biphasic, metaplastic thymoma.
