Six @entity1 with @entity75 primarily involving the @entity358 were studied. In these @entity1 , both the history and physical findings were vague and minimal. The laboratory findings also were nonspecific, although the findings of large multiple lesions in the lungs and @entity456 or effusion were more consistent with @entity706 . Histologic examination revealed lymphocytic infiltration of the @entity358 in all six @entity1 and presence of germinal or growth centers in some areas of the lesions in four. The hilar or mediastinal lymph nodes were not involved in five @entity1 so examined. Immunocytochemical study of cytoplasmic immunoglobulin revealed monoclonal lymphocytic proliferation in five @entity1 and negative staining in one @entity1 . Clinical, histologic, or immunohistochemical studies alone may not be sufficient to detect all of the @entity75 . The combined use of all of these parameters is more advantageous for accurate diagnosis of these lesions. Treatment is surgical resection. Radiotherapy or chemotherapy are used when @entity66 is present after surgery. Three @entity1 died of disseminated @entity706 96, 42, and 8 months after diagnosis, respectively, and three @entity1 are still alive at 18, 24, and 4 months, respectively.

Primary XXXX . A clinical and immunohistochemical study of six cases.
