title: Malignant lymphoma of peripheral T-lymphocyte origin: immunologic, pathologic, and clinical features in six patients.
abstract: In a continuing study of patients with lymphoproliferative diseases, six adult patients were encountered with a distinctive malignant lymphoma of peripheral T-lymphocyte origin. Cell suspensions from lymph nodes of these patients contained a pleomorphic, cytologically atypical population of lymphocytes, of which an average 58% marked as T cells in the E-rosette test. The average percent of surface immunoglobulin-bearing B cells in these suspensions was 6%; they were of polyclonal distribution. Lymph node biopsies revealed a malignant lymphoma with certain characteristic features of the organization of the infiltrate, the morphology of the lymphoid cells, and the nature of non-lymphoid cellular elements. The average age of the patients was 67 years; they presented with generalized lymphadenopathy, anorexia, and significant loss of weight. Four patients hd lung and/or pleural involvement by lymphoma at presentation. The immunologic, pathologic, and clinical features of these patients serve to characterize this recently recognized malignant lymphoma further.
