摘要：

The morphologic, immunologic and clinical features of 15 cases of primary pulmonary lymphomas were analyzed. There were 8 male and 7 female patients whose ages ranged from 21 to 71 years (mean, 54 years). The patients were heterogeneous in terms of the disease and were therefore histologically classified into three groups: low-grade B cell non-Hodgkin's lymphoma (n=9); high-grade B- or T-cell non-Hodgkin's lymphoma (n=3); and lymphomatoid granulomatosis/angiocentric T-cell lymphoma (n=3). The present study also suggested that the low-grade B-cell tumors belonged to the category of malignant lymphoma arising from mucosa- or bronchus-associated lymphoid tissue (MALT or BALT).
