Abstract
A 59-year-old male was admitted for a left hilar mass observed on a chest x-ray. He denied a history of fever, weight loss or bone pain. Chest CT showed a solid, clear-surfaced tumor near the left main bronchus. Chest MM showed a mass that was high intensity on T1 and low intensity on T2. Bronchoscopy did not diagnosis. In addtion, there were no abnormal findings on brain and abdominal CT, or on a radiographic survey of his skeleton. The patient underwent left upper lobectomy. Histological finding showed a tumor comprised sheets of moderately large and small oval cells, eccentric nuclei and few mitoses. The tumor was positive for IgG and kappa chain but negative for IgA, IgM, and lambda chain immunohistochemicaly. Therefore, extramedullary plasmacytoma was diagonised. The patient is doing well with no evidence of disease in 4 year of follow up.
