Myeloproliferative and lymphoproliferative disorders in the same patient.
A 67-year-old man developed a Philadelphia-negative myeloproliferative disorder which initially manifested as marked thrombocytosis, followed two years later by marked leucocytosis. He subsequently developed an IgG lambda plasma cell dyscrasia together with a monoclonal proliferation of circulating lymphocytes with IgM kappa surface immunoglobulin. The lymphoid neoplasm was associated with a rapidly progressive and fatal course.
