...Dan Douer; Avraham Weinbergerr; Meir Djaldetti; Jack Asherov; Israel Pick; Jack Pinkhas A patient with plasma cell leukemia and IgG (K) M-component, who developed a hyperviscosity syndrome is reported. To our knowledge, this complication has not yet been reported in plasma cell leukemia. 10 01...

...Makio Ogawa; Ronald A. Preston; Matthew D. Carson; Atsushi Komiyama; Samuel S. Spicer In a patient with plasma cell leukemia, associated with pleural effusion, ultrastructural studies of the peripheral blood plasma cells showed an abundance of cytoplasmic fibrils. The nature of fibrils...

... receptors. In macroglobulinemia, leukemic cells had one or the other of Fc γ and Fc μ receptors. In plasma cell leukemia and plasmacytoma, malignant cells had neither Fc γ nor Fc μ receptors. The disappearance of Fc receptors appears to be associated with B cell differentiation. Acta haemat. 63: 247-251...

...H. Bassan; H. Gutmann; M.. Djaldetti The clinical features and the ultrastructural findings of the bone marrow and peripheral blood plasma cells of a patient with nonsecretory myeloma and acute plasma cell leukemia are described. The internal ultrastructure of the cells was characterized...

...Hiroyuki Tsuda; Susumu Kishimoto New pyroglobulin variants were found in a patient with a typical plasma cell leukemia. One was found in the urine and proved to be a variant of Bence-Jones’ protein with a molecular weight of approximately 68,000. The other was found in the serum and appears...

...L. Resegotti; S. Ruà; C. Dolci; B. Grosso; M. Pistone; D. Testa A case is reported of an elderly patient with generalized lymphadenopathy who, at presentation, showed a blood and bone marrow picture suggestive of plasma cell leukemia, polyclonal hypergammaglobulinemia restricted almost exclusively...

...M. Lishner; R. Lang; I. Jutrin; M. Ravid Primary plasma cell leukemia was diagnosed in a previously healthy 58-year-old man. The unusual presentation with concomitant multiple osteolytic lesions and hepatosplenomegaly, the favorable response to aggressive chemotherapy with COAP, and the relatively...

... this patient might respond with a false-positive result in the CA125 immunoradiometric assay. The other patient had an IgG-λ type plasma cell leukemia with the culture supernatant from peripheral mononuclear cells also showing a high level of CA125 activity. These observations may suggest that in plasma cell...

...Carlos Panizo; José Rifón; Pablo Rodríguez-Wilhelmi; Braulia Cuesta; Eduardo Rocha Primary plasma cell leukemia (PCL) is a rare form of plasma cell neoplasm with a poor prognosis. Conventional melphalan-based treatments have been most disappointing. We report the case of a 62-year-old man...
