ABSTRACT
A 57-year-old female was admitted because of chest and back pain. Computed tomography (CT) revealed that many well-marginated lymph nodes were located in mediastinum and abdominal para-aortic area, especially in the right lower mediastinum. These lymph nodes were enhanced at contrast material-enhanced CT. We performed thoracoscopic surgery. The histopathologic diagnosis was multicentric Castleman disease (MCD). MCD should be considered in the differential diagnosis of multiple lymph nodes swelling with hyper globulinemia. Thoracoscopic surgery is the useful method to resect the lymph nodes and diagnose MCD.

An asymptomatic 66-year-old female was admitted because of an abnormal shadow on chest X-ray. Computed tomography (CT) revealed that a well-marginated round mass with low density, about 3 cm in diameter, was located in the right anterior superior mediastinum. The border was partially enhanced at contrast material-enhanced CT. Magnetic resonance imaging (MRI) [T 2-weighted] showed the lesion as a high intensity tumor. We performed thoracoscopic surgery and resected the easy-bleeding tumor completely. The tumor was dark red in color and contained old blood. The histopathological diagnosis was hemangioma. There was no recurrence for 3 years. Hemangiomas should be considered in the differential diagnosis of well-marginated masses. Thoracoscopic surgery is the very useful methods to resect the mediastinal hemangioma.
