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...

The radiographic appearance of bone metastases is usually determined by tumor histology and can be osteolytic, osteoblastic, or mixed. We present a patient with coexistent bone metastasis from multiple myeloma and prostate adenocarcinoma who exhibited synchronous bone involvement of both histologies within the same bone lesion, a rare phenomenon that has not been previously reported and led to atypical radiographic findings. The radiograph of a 71-year-old man with thigh swelling and pain demonstrated a lytic femoral lesion...

RATIONALE: Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is classified as a biliary tract manifestation of immunoglobulin G4-related disease (IgG4-RD). Glucocorticoid is the first-line therapy for most patients, but the optimal starting dose, adequate maintaining dose and withdrawal time remain disputable. PATIENT CONCERNS: An elderly male patient presented to our hospital with neoplasms of the bile duct and pancreas at first visit in December 2011...

Multiple myeloma (MM) is a malignant neoplasm of plasma cell origin. It usually has a multicentric origin within the bone. It contributes to about 1% of all malignancies and 15% of all hematologic malignancies. There is a monoclonal proliferation of abnormal plasma cells in this disease that results from a single malignant precursor that has undergone an uncontrolled mitotic division. Later, these cells produce one type of immunoglobulin light chain, either kappa or lambda. We present a case of a 46‑year‑old male patient who presented with a swelling of the mandible...

Renal transplant recipients exhibit an increased risk of developing plasma cell neoplasms (PCNs; comprising multiple myeloma and plasmacytoma); however, multiple myeloma manifesting with refractory extramedullary plasmacytomas associated with Epstein-Barr virus are markedly rare in these patients. In the present case report, an unusual case of refractory multiple myeloma with multiple extramedullary plasmacytoma (including liver, vertebrae, breast, muscle, skin and soft tissues) was presented. The patient exhibited mild bone marrow infiltration which was successfully treated with novel agents, including bortezomib and lenalidomide, followed by autologous stem cell transplantation (ASCT)...

BACKGROUND: HIV-infected patients are at a higher risk to develop malignancies than general population. Although AIDS-related malignancies are a common feature of late-stage disease, patients under successful antiretroviral therapy also have an increased risk for development of non-AIDS malignancies. OBJECTIVE: To compare the frequency and characteristics of adults HIV-infected patients and general population who died of malignancies in Bahia, Brazil from January 2000 to December 2010...

Monoclonal gammopathies are characterized by the overproduction of monoclonal Ig (MIg) detectable in the serum or urine resulting from a clonal proliferation of plasma cells or B lymphocytes. The underlying hematologic conditions range from malignant neoplasms of plasma cells or B lymphocytes, including multiple myeloma and B-cell lymphoproliferative disorders, to nonmalignant small clonal proliferations. The term MGUS implies presence of an MIg in the setting of a "benign" hematologic condition without renal or other end organ damage...

Multiple myeloma (MM) is a debilitating neoplasm of terminally differentiated plasma B-cells that has resulted in over 13,000 deaths in 2017 alone. Combination therapies involving melphalan, a small molecule DNA alkylating agent, are commonly prescribed to patients with relapsed/refractory MM, which necessitates the stratification of responding patients to minimize toxicities and improve quality of life. Here, we evaluated the use of 18 F-FDOPA, a clinically available positron emission tomography (PET) radiotracer with specificity to the L-type amino acid transporter-1 (LAT1), which also mediates melphalan uptake, for imaging melphalan therapy response in a preclinical immunocompetent model of MM...

Light chain (AL) amyloidosis is a plasma cell neoplasm associated with insoluble fibril deposition from clonal immunoglobulin chains systemically. The disease is associated with high early mortality and morbidity owing to advanced organ deposition as well as lack of proven de-fibrillogenic therapies. Pre-clinical and retrospective clinical data suggests that doxycycline has benefit in AL amyloidosis. The ongoing DUAL study is a single center, open label, phase 2 study in which patients with AL amyloidosis who are undergoing clone-directed therapy for the underlying neoplasm with oral doxycycline given for 1 year to test the hypothesis that prolonged doxycycline use will be safe, feasible, and lead to reduced early mortality in systemic AL amyloidosis and hasten organ amyloid response...

REVIEW
Shaji K Kumar, S Vincent Rajkumar
Multiple myeloma (MM) is a plasma cell neoplasm that accounts for 2% of all haematological malignancies and predominantly affects older individuals (with a median age at diagnosis of 65-70 years). MM is consistently preceded by the clinically recognized precancerous stages monoclonal gammopathy of undetermined significance and smouldering MM. Thus far, MM has been considered as a single disease entity, but the clinical presentation, response to treatment, and survival outcomes of patients with MM are quite heterogeneous and highly dependent on a set of chromosomal abnormalities that can be identified in nearly all of them...

Multiple myeloma (MM) is a hematological neoplasm which results in diffuse or focal bone infiltration and extramedullary lesions. It's reported that infiltration of organs by plasma cells indicated worse prognosis, but the prognosis of patients with bone-related extramedullary disease (bEMD) is still unkown. 114 newly diagnosed MM patients were retrospectively reviewed. Results showed that the clinical features, overall survival (OS) and progression free survival (PFS) of patients with and without bEMD had no statistical significance...

BACKGROUND: Although hyperviscosity syndrome in plasma cell dyscrasia (PCD) and thrombosis in myeloproliferative neoplasm (MPN) are major causes of morbidity and mortality, blood viscosity measurements are often underutilized. OBJECTIVE: This study aimed to characterize whether whole blood viscosity (WBV) or plasma viscosity (PV) could be predictive of hyperviscosity syndrome in PCD and could be elevated in subgroups of MPN. METHODS: A total of 75 patients with hematologic diseases: PCD (n = 26), MPN (n = 25) including polycythemia vera (P...

Background: It is unclear whether the established association between cutaneous melanoma (CM) and lymphoid neoplasms (LNs) differs across LN subtypes. This study quantifies risk for developing CM after specific LNs and, conversely, for developing specific LNs after CM, as well as assessing clinical impact. Methods: We identified a cohort of Caucasian adults (age 20-83 years) initially diagnosed with CM or LN, as reported to 17 US population-based cancer registries, 2000-2014...

BACKGROUND: Despite increased usage of multiparameter flow cytometry (MFC) to assess diagnosis, prognosis, and therapeutic efficacy (minimal residual disease, MRD) in plasma cell neoplasms (PCNs), standardization of methodology and data analysis is suboptimal. We investigated the utility of using the mean and median fluorescence intensities (FI) obtained from MFC to objectively describe parameters that distinguish plasma cell (PC) phenotypes. METHODS: In this retrospective study, flow cytometry results from bone marrow aspirate specimens from 570 patients referred to the Myeloma Institute at UAMS were evaluated...

A 70-year-old man was referred to our hospital with exacerbation of diabetes. His blood tests showed elevated levels of serum IgG4 and HbA1c. Computed tomography of the pancreatic body demonstrated a weakly enhanced mass, 2 cm in size, with indistinct borders. Magnetic resonance cholangiopancreatography revealed a narrowing of the main pancreatic duct (MPD) at the pancreatic body, a markedly dilated upstream duct, and a slightly dilated downstream duct. Endoscopic ultrasonography demonstrated an iso-hypoechoic heterogeneous mass, protruding and spreading in the pancreatic duct...

The inflammatory myofibroblastic tumor (IMT) is a rare lesion of unclear etiology and variable clinical course, consisting of a proliferation of fibroblasts and myofibroblasts, mixed with inflammatory cells. Synonyms of IMT are inflammatory pseudotumor and plasma cell granuloma reflecting the alleged inflammatory nature attributed to this lesion, even though this heterogeneity in the disease denomination is probably involved in a dispersion of the literature data. Among primary pulmonary neoplasms, it represents the most frequent endobronchial tumor of childhood and beyond the lung it has been described mainly in the bladder, mediastinum and mesentery...

High-dose chemotherapy combined with autologous hematopoietic stem-cell transplantation (ASCT) is the first-line treatment for multiple myeloma. Yet, some patients will relapse. Testicular plasmacytoma which rarely happens can be isolated or associated with progressive multiple myeloma. Here, we report a case of multiple myeloma (MM) undergoing ASCT when the patient obtained complete remission. He developed painless right testicular swelling after nearly 3 years since the ASCT. After radical orchiectomy, histopathology showed diffuse abnormal plasma cells infiltration of the testicular tissue...

Non-Hodgkin lymphomas (NHL) are a group of cancers with highly heterogeneous biology and clinical features. Statins are increasingly prescribed to prevent cardiovascular diseases. Early evidence shows a preventive effect of statins for some cancers, but their effect on NHL risk is unclear. We conducted a population-based nested case-control study involving 5,541 NHL cases and 27,315 controls matched for gender, age, place of residence and length of period of available prescription drug data. We assessed the use of statins prior to diagnosis (excluding the 12 months prior to the index date)...
