BACKGROUND: Extramedullary plasmacytoma (EMP) is a plasma cell malignancy that originates in soft tissues without evidence of systemic spread, and its management differs from other plasma cell neoplasms. The purpose of the present study was to evaluate the role of initial 18 F-FDG PET/CT in the management of patients with clinical suspected EMP. METHODS: 18 F-FDG PET/CT scans performed in 21 patients (M/F = 12/9, mean age 51.1 ± 15.3 years) with clear suspicion of EMP from 2006 to 2015 were analysed retrospectively...

Recently, we identified ELL2 as a susceptibility gene for multiple myeloma (MM). To understand its mechanism of action, we performed expression quantitative trait locus analysis in CD138+ plasma cells from 1630 MM patients from four populations. We show that the MM risk allele lowers ELL2 expression in these cells (Pcombined  = 2.5 × 10-27 ; βcombined  = -0.24 SD), but not in peripheral blood or other tissues. Consistent with this, several variants representing the MM risk allele map to regulatory genomic regions, and three yield reduced transcriptional activity in plasmocytoma cell lines...

RATIONALE: Solitary extramedullary plasmocytoma may arise in any organ, either as a primary tumor or as part of a systemic myeloma; if it rarely affects bladder, it presents with urinary symptoms. We describe the first case of asymptomatic BP occasionally diagnosed in a patient with ascites. PATIENT CONCERNS: A 74-year-old woman with hepatitis C virus (HCV)-related liver cirrhosis presented with ascites and no urinary or other symptoms. DIAGNOSES: Routine blood tests were within normal ranges, except for mild elevation of transaminases due to chronic hepatitis...

Multiparameter flow cytometry (MFC) has become standard in the management of patients with plasma cell (PC) dyscrasias, and could be considered mandatory in specific areas of routine clinical practice. It plays a significant role during the differential diagnostic work-up because of its fast and conclusive readout of PC clonality, and simultaneously provides prognostic information in most monoclonal gammopathies. Recent advances in the treatment and outcomes of multiple myeloma led to the implementation of new response criteria, including minimal residual disease (MRD) status as one of the most relevant clinical endpoints with the potential to act as surrogate for survival...

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) is a paraneoplastic syndrome driven by plasma cell dyscrasias. We report a patient with novel initial manifestation of polyneuropathy, which was considered due to Sjögren's syndrome but with poor response to methylprednisolone (120 mg/d) and intravenous immunoglobulin (IVIg). Further investigation by imaging tests and following biopsy eventually confirmed the diagnosis of POEMS syndrome secondary to solitary plasmocytoma...

A 79-year-old man presented with a large tumor on the left side of his head, which had grown over 5 years. Regional lymph nodes were impalpable and computed tomography revealed no signs of bone infiltration. Histology showed that the entire dermis was filled with amorphous eosinophilic material. Immunohistochemistry was negative for cytokeratin, but showed that the dermis and parts of the subcutis were filled with amyloid consisting of immunoglobulin light chains. There were no signs of paraproteinemia or underlying plasmocytoma...

Multiple myeloma (MM) is a neoplasia characterized by the proliferation of plasmacytoid cells, which produce abnormal immunoglobulins. It frequently creates local and systemic complications such as pathologic fractures and renal disease. This article reports the case of a 70-year-old man presenting a pathologic fracture of the right mandibular angle secondary to a plasmocytoma. He had a history of a previous pathologic fracture of the left mandibular angle 13 years before that was treated elsewhere, but no documentation was available...

Presentation of multiple myeloma with bone lesions is common. It is vital that differentiation between nonsecretory multiple myeloma and plasmocytoma be done and that each disorder be treated accordingly. In this paper, we present a patient with nonsecretory multiple myeloma, who suffered from distal humerus fracture with severe bone destruction, renal failure, hypercalcemia and anemia.

Multiple myeloma is a malignant tumour characterized by proliferation of a single clone of plasma cells, this cell line will produce large amount of ineffective immunoglobulins that are ineffective at fighting infection resulting in immunosuppression. These are medullary tumours most of the time; however, in rare cases they may arise extra medullary. The incidence of extramedullary plasmocytoma is about 5% and they arise in the chest most of the time; but they can also arise in other body systems like gastrointestinal system, which is involved in 10% of the time...

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally...

Cancer of unknown primary site is a metastasis developed by the positive feedback loops of primary cancer forming extreme cancer robustness. Such robustness occurs only in metastatic cancer or in relapsed lymphoma, myeloma, plasmocytoma, or leukemia. However, when it develops in primary cancer, hypoxic microenvironment generates positive feedback loops which hyperactivate AKT locus, forming extreme robustness that forcing cancer cells to migrate to the distant site, but primary cancer loosing that property or remains silent...

A cancer positive-feedback loops conversion is the phenomenon and principal mechanism for AKT locus chemotherapy. Such chemotherapy is the approach to target cancer robustness and complexity through the AKT signaling locus. The hypoxic cancer microenvironment generates a powerful signaling interactome with positive-feedback loops that generates cancer robustness through the AKT locus. This complexity and robustness can be successfully halted in leukemia, lymphoma, myeloma, plasmocytoma, sarcoma, and carcinoma by converting cancer positive-feedback loops into negative-feedback loops, achieved through the AKT dephosphorylation by redox balancing change...

BACKGROUND: Multiparameter flow cytometry (MFC) identification and characterization of plasma cells (PCs) is a useful tool to support diagnosis, prognostication, and monitoring of PC diseases (PCD). Currently, the number of MFC markers suited for the identification of PC remains limited. Moreover, antibody therapies against PC-associated markers further compromise the utility of the most widely used reagents (e.g., CD38). Despite markers other than CD38 and CD138 are recognized as potentially useful PC-identification markers, no study has comparatively evaluated their performance in combination with CD38 and CD138...
