Multiple myeloma is a debilitating malignancy arising from plasma cells. These malignant plasma cells called myeloma cells proliferate and infiltrate the bone marrow. The disease is characterized by the presence of a monoclonal protein in plasma and/or the urine. In this report, we present a case of biclonal multiple myeloma which showed two M bands on serum protein electrophoresis. The patient had elevated serum IgA and IgG levels. To reveal the nature of M bands or clonality, serum Immunofixation study was performed which revealed IgA with Lambda and IgG with Kappa light chains...

Myeloma cells are known to show varied morphology and various types of nuclear or cytoplasmic inclusions. There are a few reports of myeloma with presence of pseudo-Gaucher type histiocytes; however myeloma cells itself resembling storage histiocytes is distinctly uncommon. We report images of plasma cells resembling storage cells from a case of IgG/lambda plasma cell myeloma. Hematopathologist must be aware of such varied morphology of plasma cells especially while dealing with extra medullary plasmacytomas...

A 69-year-old man was diagnosed with multiple myeloma (IgG-κ) in January 2012. He received autologous hematopoietic stem cell transplantation in August 2012 and subsequently maintained a stringent complete remission. In March 2016, he relapsed and was treated with lenalidomide and low-dose dexamethasone (Ld). On day22, he developed an asymptomatic venous thromboembolism (VTE) despite receiving prophylactic aspirin treatment. Thus, heparin and warfarin were administered. However, his prothrombin time-international normalized ratio did not remain within the target range of 2-3...

BACKGROUND: Pure red cell aplasia (PRCA) is an uncommon disease which involves an almost complete absence of the erythroid lineage in bone marrow (BM) and causes severe anemia. Cases due to monoclonal gammopathy occurring in plasma cell disorder have been infrequently reported. Here we report a case of PRCA associated plasma cell disorder, especially monoclonal gammopathy of undetermined significance (MGUS). METHODS: A 55-year-old male visited the ER due to general weakness...

Multiple myeloma is characterised by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. This clone of plasma cells proliferates in the bone marrow, resulting in extensive skeletal destruction with osteolytic lesions, osteopenia and pathological fractures. Additional disease-related complications include hypercalcaemia, renal insufficiency, anaemia and infection. We present the case of a 64-year-old woman presenting with rapid onset, painful distal symmetrical lower limb weakness and an acute kidney injury...

Plasma cellmyeloma constitutes about 10% of all hematologic malignancies. Metastatic cutaneous lesions without underlying bony involvement are rare and associated with advanced disease, poor prognosis and high tumor burden. IgG is the most common subtype and IgD is believed to have a more aggressive course.

An 82-year-old woman presented with a 9-month history of multiple, well-defined skin lesions on her neck and upper chest, progressively increasing in size. Histological examination of a skin biopsy showed a regular epidermis. In the dermis, granulomatous changes with central necrobiosis were found which extended focally into the subcutaneous fat. The necrobiotic areas were surrounded by Touton cells and foreign-body giant cells. Laboratory analysis revealed leucopenia. Serum electrophoresis and immunofixation disclosed the presence of an IgG-λ paraprotein...

The high frequency of monoclonal gammopathy in adult patients with C3 glomerulopathy (C3G) emphasizes the role of the monoclonal immunoglobulin (MIg) in the occurrence of renal disease and raises the issue of the therapeutic management. The aim of the study was to evaluate the effect of chemotherapy in a large cohort of patients with MIg-associated C3G. Fifty adult patients with MIg and biopsy-proven C3G were extracted from the French national database of C3G. We retrospectively compared renal outcomes in patients who received or not chemotherapy targeting the underlying B-cell clone...

Monoclonal gammopathy of renal significance (MGRS) regroups renal disorders caused by a monoclonal immunoglobulin without overt hematological malignancy. MGRS includes tubular disorders, glomerular disorders with organized deposits, and glomerular disorders with non-organized deposits, such as proliferative glomerulonephritis with monoclonal IgG deposits. Since glomerular involvement related to monotypic IgA deposits is poorly described we performed retrospective analysis and defined clinico-biological characteristics, renal pathology, and outcome in 19 referred patients...

The most commonly used techniques to measure vitamin D are automated immunoassays which are known to be affected by interferences, especially from immunoglobulins present in the patient's serum. We present a case of a patient with myeloma in whom interference with the vitamin D assay was identified. An eighty-three year old female, known to have IgG myeloma was found to have a high concentration of 25-OH vitamin D on a routine test without any signs of vitamin D toxicity. She was not taking vitamin D supplements or any other multivitamin preparation and had minimal sun exposure...

A 13-year-old, castrated male Maine Coon cat was presented to Oklahoma State University Boren Veterinary Medical Teaching Hospital for yearly echocardiographic examination monitoring hypertrophic cardiomyopathy (HCM) diagnosed in 2003. Physical examination revealed a heart murmur and premature beats, likely related to HCM, but was otherwise unremarkable. A biochemistry profile revealed a hyperglobulinemia (6.3 g/dL). Cytologic examination of fine-needle aspirates from liver and spleen revealed increased numbers of plasma cells and mast cells, confirmed with subsequent histologic examination...

OBJECTIVES: Monoclonal gammopathy of undetermined significance (MGUS) is a premalignancy preceding multiple myeloma (MM) or related disorders. Neurological symptoms caused by the monoclonal immunoglobulins or free light-chains are often associated with a high morbidity. We analyzed the prevalence of neuropathy, clinical features and the long-term outcome in 223 patients (pts.) with MGUS. PATIENTS AND METHODS: Between 1/2005 and 3/2015, 223 adult pts. with MGUS were identified in our database...

The pathological progression from benign monoclonal gammopathy of undetermined significance (MGUS) to smoldering myeloma (SMM) and finally to active myeloma (MM) is poorly understood. Abnormal immunoglobulin G (IgG) glycosylation in myeloma has been reported. Using a glycomic platform composed of hydrophilic interaction UPLC, exoglycosidase digestions, weak anion-exchange chromatography, and mass spectrometry, polyclonal IgG N-glycosylation profiles from 35 patients [MGUS (n = 8), SMM (n = 5), MM (n = 8), complete-response (CR) post-treatment (n = 5), relapse (n = 4), healthy age-matched control (n = 5)] were characterized to map glycan structures in distinct disease phases of multiple myeloma...

Immunoglobulin (Ig) heavy/light chain (HLC) assays enable the separate quantification of the different light chain types of each Ig class. We retrospectively analyzed the correlation of heavy/light chain ratio (HLCR) with clinical status and its impact on outcome in 120 patients with multiple myeloma (MM). Abnormal HLCR was seen more frequently in patients with poorer myeloma response, and it appeared to be more sensitive for detecting clonality in IgA myeloma compared to IgG myeloma after treatment. Among the 85 patients who achieved ≥VGPR, the patients remained HLCR abnormal were showed significantly shorter overall survival (OS) compared to those achieving a normal HLCR (not reached vs...

Accumulating evidences have shown that adipokines secreted from adipocytes contributes to tumor development, especially leptin. However, underlying mechanisms remain unclear. This study aims to explore the effect of leptin on development and chemoresistance in multiple myeloma cells and the potential mechanism. Analysis of levels of adipokines including leptin and adiponectin in 28 multiple myeloma patients identified significantly higher leptin compared with 28 normal controls(P < 0.05), and leptin level was positively correlated with clinical stage, IgG, ER, and ß2MG...

Simultaneous occurrence of T-cell and B-cell neoplasms is rare, and etiologic relationships between these 2 malignancies are poorly understood. We describe the case of a 66-year-old woman who was admitted to the hospital because of fever, hemoptysis, lymphadenopathy, and skin rash. Enlarged lymph nodes in axillary, pectoral, paratracheal, and periportal regions as well as slight hepatomegaly and splenomegaly were confirmed. A peripheral blood smear revealed rouleaux formation and numerous circulating plasma cells, with plasmacytoid lymphocytes...

BACKGROUND: Recently, we described a novel autoantibody, anti-Sj/ITPR1-IgG, that targets the inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) in patients with cerebellar ataxia. However, ITPR1 is expressed not only by Purkinje cells but also in the anterior horn of the spinal cord, in the substantia gelatinosa and in the motor, sensory (including the dorsal root ganglia) and autonomic peripheral nervous system, suggesting that the clinical spectrum associated with autoimmunity to ITPR1 may be broader than initially thought...

The diagnostics and follow-up of monoclonal gammopathies such as multiple myeloma require precise analysis of the monoclonal component as well as the other immunoglobulins isotypes, which might be limited by the sensitivity of standard laboratory methods. New serum biomarkers were developed for routine practice in the last decades, such as the free light chain assays and more recently the heavy/light chain assay<strike>s</strike>. Studies have shown that serum free light chain measurement was useful in the identification and follow-up of pauci or nonsecretory myeloma, free light-chain multiple myeloma and AL amyloidosis...

Acquired coagulopathies are common; uncommonly, adsorption of coagulation factors from the circulation into the tissues by pathologic amyloid exceeds the body's ability to produce factor and results in acquired factor deficiency. When amyloidosis does cause a coagulopathy, it is most often acquired factor X deficiency, but there are rare reports of amyloidosis being associated with other acquired factor deficiencies. We investigated a case of a severe bleeding diathesis, the cause of which was combined acquired factor V deficiency and concomitant acquired von Willebrand syndrome...
