Extramedullary Myeloma
Extramedullary myeloma (EMM) is the presence of clonal plasma cells (PCs) outside the bone marrow in a patient with multiple myeloma (MM). EMM can be present at the time of initial diagnosis (primary EMM) or at the time of relapse (secondary EMM) [1]. EMM has an incidence of 7% to 20% at presentation and 6% to 20% during disease progression [2]. Using sensitive imaging techniques including MRI ...

متن کاملNasal septum extramedullary plasmacytoma.
INTRODUCTION Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone--solitary osseous plasmacytoma, or in soft tissue--extramedullary plasmacytoma (EMP). EMP represents less than 1% of all head and neck malignancies. CASE REPORT We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive...
متن کاملExtramedullary Waldenström macroglobulinemia.
Disease assessment in Waldenstrom Macroglobulinemia (WM) is dependent on the percent involvement of B-cell neoplasm in the bone marrow and IgM paraprotein in the serum. A subset of patients also demonstrates extramedullary involvement, which is infrequently examined. The role of extramedullary involvement in the diagnosis and prognosis of WM is poorly understood. The purpose of this study is to...
متن کاملThis extraordinary extramedullary haematopoiesis.
In this issue of the Journal, Stroo et al. [1] published their findings on the engraftment of the intact and ischaemic kidney by haematopoietic stem cells (HSC). Specifically, these investigators demonstrated that systemically administered HSC preferentially migrate to the ischaemic kidney and that this process is SDF-1/CXCR4 independent. Indeed, ischaemia-induced retention of hypoxia-inducible...
