A 57 years-old man was referred to our hospital because of an abnormal shadow in the left hilum on a screening chest X-ray. His physical exam and laboratory data were not notable. Chest computed tomography (CT) showed two nodules one of which is cystic in the anterior mediastinum, and positron emission tomography with 18F-fluoro-2-deoxy-D-glucose showed relatively mild uptake in both tumors. We suspected mucosa associated lymphoid tissue (MALT) lymphoma or multiple thymomas, and performed thoracoscopic thymo-thymectomy. The operative findings showed two separated tumors in the thymus. Histopathological examination revealed that both tumors were type B1 thymomas of 35 mm and 40 mm in size. Since both tumors were encapsulated without continuity, multi-centric origin was suggested.
