Abstract
Plasma cell leukemia is a rare yet aggressive form of multiple myeloma characterized by high levels of plasma cells circulating in the peripheral blood. We recently experienced a case of plasma cell leukemia that had been in stringent complete remission for nine years after autologous stem cell transplantations with subsequent courses of lenalidomide maintenance therapy, and then relapsed as an extramedullary plasmacytoma in the central nervous system. Assessment of the bone marrow did not prove proliferation of plasma cells at relapse, but imbalanced elevation of serum levels of free light chains was observed without changes in other clinical biomarkers including immunoglobulin levels. Salvage chemotherapy with isatuximab, pomalidomide, and dexamethasone (IsaPD) was promptly initiated. After two courses of IsaPD, significant remission was achieved and the neuronal symptoms completely resolved. When excessive serum levels of clonotypic free light chains are noted, their significance should be carefully assessed even when plasma cell propagation in the bone marrow is not observed. In such cases, hematologists should search for extramedullary proliferation of plasma cells, including in the immune-privileged central nervous system.

Abstract
Primary plasma cell leukaemia (pPCL) is a rare and aggressive form of plasma cell malignancies with a very poor prognosis. Compared to other plasma cell malignancies the tendency to extramedullary spread is increased; however central nervous system (CNS) involvement is rare and only reported in few cases. We report the case of a 61-year-old man who was diagnosed with pPCL and achieved a complete remission after autologous stem cell transplantation but had a relapse in the CNS without systemic disease.

Abstract
Primary plasma cell leukemia (PPCL) is a rare hematologic malignancy characterized by the proliferation of plasma cells in blood, bone marrow, and other organs in the absence of established multiple myeloma. PPCL has a poor prognosis when treated with conventional therapy for multiple myeloma. We describe here 17 new cases of PPCL who underwent stem-cell transplantation (SCT) (2 cases observed by the authors and 15 cases from the International Bone Marrow Transplant Registry [IBMTR]). The first case was diagnosed in a 21-year-old male who presented with leukocytosis and acute renal failure. He was treated with hyper-CVAD, entered complete remission, and then proceeded to high-dose chemotherapy with peripheral stem-cell support. He is currently in complete remission 23 months after initial diagnosis and 19 months after autologous SCT. The second case was observed in a 31-year-old male who presented with leukocytosis and hepatic infiltration with plasma cells. He was treated with VAD chemotherapy and underwent allogeneic bone marrow transplantation from his HLA-identical sister. He remained in complete remission for 3 years and then developed progressive refractory disease, dying 7 years after the initial diagnosis. In addition to these 2 cases, 15 further unpublished cases of PPCL from the IBMTR are reported here (treated between 1993 and 2001, 6 by autologous and 9 by allogeneic transplantation). Finally, the features of PPCL, the outcome, published data of SCT for PPCL, and indications for treatment are discussed.

Abstract
Autologous peripheral blood stem cell transplantation (PBSCT) is a costly procedure. In India, the cost varies from US$20000 to 25000 and most patients cannot afford it. Using several cost-cutting measures, we were able to treat a patient with plasma cell leukaemia by autologous PBSCT. A 42-year-old-male presented with plasma cell leukaemia. He was treated with VAD therapy, followed by high-dose cyclophosphamide and granulocyte colony-stimulating factor (G-CSF) for mobilization of peripheral blood stem cells. The patient was conditioned with high dose melphalan, followed by autologous PBSCT. The procedure was performed in a municipal hospital in which there was no prior experience with stem cell transplantation. Costs were reduced by: (i) using oral medication whenever possible; (ii) having a relative of the patient prepare his food under medical guidance; (iii) starting G-CSF on day 7 rather than on day 1; (iv) short-term storage of the PBSC in an ordinary refrigerator at 4 degrees C without cryopreservation; (v) infusing a large number of CD34+ cells, which shortened the time to engraftment; (vi) delegating many of the functions of a marrow transplant nurse to a resident physician. The cost of transplantation was thereby reduced to about US$ 6000, with successful engraftment by day +13. The patient remained in remission for 7 months, after which he relapsed and was treated with chemotherapy and electron beam radiation to the skin.
