Solitary plasmacytoma of the skull is very rare, and only a few cases have been reported in the literature. It remains controversial whether solitary plasmacytoma of the skull is essentially identical with solitary plasmacytoma of bone or not. Solitary plasmacytoma of bone including solitary plasmacytoma of the skull is characterized by a radiologically solitary bone lesion, neoplastic plasma cells in the biopsy specimen, fewer than 5% plasma cells in bone marrow, <2.0 g/dl monoclonal protein in the serum when present and negative urine test for Bence Jones protein (monoclonal light chain)...

A 55-year-old man was admitted to our institute to undergo evaluation for proteinuria (5.4 g/day) with lambda-type Bence-Jones protein (BJP). Primary AL amyloidosis and acquired factor X deficiency were diagnosed. High-dose melphalan combined with autologous stem cell transplantation was performed. After three years, the patient's proteinuria normalized, he was negative for urinary BJP, and his factor X activity improved to 105%. Serial renal biopsy showed no progression of amyloid deposition at a biopsy after 5 years, but showed a slight increase in the amyloid deposition after 11 years...

It is now accepted that the ability of a protein to form amyloid fibrils could be associated both kinetic and thermodynamic protein folding parameters. A recent study from our laboratory using recombinant full-length (encompassing the variable and constant domain) immunoglobulin light chains found a strong kinetic control of the protein unfolding for these proteins. In this study, we are extending our analysis by using urine-derived Bence Jones proteins (BJPs) from five patients with light chain (AL) amyloidosis and four patients with multiple myeloma (MM)...

OBJECTIVES: Many radiologists and clinicians still consider multiple myeloma (MM) and monoclonal gammopathies (MG) a contraindication for using iodine-based contrast media. The ESUR Contrast Media Safety Committee performed a systematic review of the incidence of post-contrast acute kidney injury (PC-AKI) in these patients. METHODS: A systematic search in Medline and Scopus databases was performed for renal function deterioration studies in patients with MM or MG following administration of iodine-based contrast media...

Multiple myelomas (MM) of the immunoglobulin D (IgD) subtype is rare amongst plasma cell malignancies. It can present a diagnostic challenge because of the low amount of immunoglobulin in the serum. The amount of monoclonal (M)-protein is often undetectable on electrophoresis. Historically, survival in these patients was typically shorter compared to the immunoglobulin A (IgA) and immunoglobulin G (IgG) subtypes due to advanced disease upon presentation. With the advent of better diagnostic techniques, the prognosis of this disease is changing...

Primary cutaneous plasmacytosis is a rare cutaneous disorder with extensive cutaneous plaques/papules mainly on the trunk and face. Cases have mostly been documented from Japan. We present here a rare case of cutaneous plasmacytosis from India of Mongolian descent. This 50-year-old female from Mizoram had extensive maculo-papular violaceous plaques distributed on the face, axillae, trunk and lower extremities. Initial and repeat skin biopsy revealed dense perivascular and periadnexal mature plasma cells. She also had lymphadenopathy...

OBJECTIVE: Primary amyloidosis is a disease with a poor prognosis and multi-organ involvement. Here, we report the clinical and pathological features of a patient with primary amyloidosis featuring autonomic neuropathy as the initial symptom and albuminocytologic dissociation in the cerebrospinal fluid (CSF). METHODS: The patient was a 60-year-old Chinese male with numbness, orthostatic hypotension, and gastrointestinal symptoms. For diagnosis, we performed an electromyogram (EMG), lumbar puncture, Bence Jones protein urine test, serum electrophoresis blood test, sural nerve and rectal membrane biopsies, transthyretin (TTR) gene sequencing, and bone marrow puncture...

Myeloma cast nephropathy is an obstructing disorder of renal tubules, caused by precipitation of Bence Jones proteins. Myeloma-like cast nephropathy (MLCN) has been reported in the literature to occur in various primary renal and nonrenal diseases. We present a series of three rare cases of cast nephropathy, two of which are HIV patients, and the third patient is receiving cisplatin-based chemotherapy. However, in all three patients plasma cell dyscrasia has been ruled out. A 30-year-old male was admitted to the hospital with facial cellulitis...

Familial amyloidotic polyneuropathy is a genetically determined disease characterized by deposition of an anomalous transthyretin. A high index of suspicion is needed for this multisymptomatic and lethal disease to be diagnosed. The patient was a 70-year-old male examined due to hypesthesia in the hands and feet, plus difficulty walking. A neurophysiological study delivered the diagnosis of axonal sensorimotor polyneuropathy. He later developed cardiac symptoms and diarrhea. Urine laboratory analyses revealed a monoclonal spike of light chains (kappa)...

Identifying appropriate strategies for sustainable harvest is a challenge for many terrestrial vertebrate species because of uncertain system dynamics, limited data to inform population models, and potentially conflicting objectives that seek to harvest and maintain populations at desirable levels. The absence of monitoring and assessment infrastructure needed to regularly estimate abundance accentuates this challenge for many species, and limits application of rigorous state-dependent frameworks for decision making that are commonly advocated in natural resource management...

Renal impairment (RI) in patients with multiple myeloma (MM) is associated with poor prognosis. In this population-based cohort study, we assessed the effects of renal response, evaluated according to the IMWG-criteria, on overall survival (OS) in patients with newly diagnosed MM with RI at presentation. All included patients were diagnosed between January 2005 and January 2014 with MM and RI in Friesland, a province of the Netherlands. Of the 131 included patients, 61% achieved renal response. Using a time-varying exposure Cox model, no difference in OS between renal response and non-response was observed (HR = 1...

We report a 70-year-old woman with Sjögren's syndrome who had severe renal dysfunction with mild proteinuria and elevated urinary low-molecular-weight proteins. Based on these clinical presentations, interstitial nephritis due to Sjögren's syndrome was strongly suspected. Unexpectedly, renal pathology revealed amyloid light-chain (AL) lambda-type depositions predominantly in the vasculatures with severe tubulointerstitial damage. Concentrated urine immunofixation was positive for Bence Jones lambda-type monoclonal proteins...

Multiple myeloma is a disorder of plasma cells which can involve kidneys in the form of cast nephropathy. Neoplastic plasma cells produce either complete immunoglobulins or fragments of immunoglobulins leading to a monoclonal spike in the serum and/or Bence Jones proteinuria. Very few patients present as non-secretory myeloma when no immunoglobulins (M spike) are produced or only light chains are secreted which can only be detected in urine. Acute renal failure due to cast nephropathy can rarely be the first presentation of multiple myeloma...

The paper describes a clinical case of a female woman with nephropathy due to light chain deposition disease caused by secretion of κ Bence-Jones protein. Complete immunochemical remission was achieved after induction therapy using a bortezomib + cyclophosphamide + dexamethasone regimen. Renal function remained unchanged (glomerular filtration rate 16 ml/min), there was a reduction in proteinuria from 5.8 to 2.6 g/day. High-dose melphalan (200 mg/m2) chemotherapy with peripheral blood stem cell autotransplantation was performed as consolidation of remission...

A female diagnosed as having immune thrombocytopenic purpura (ITP) was found to be simultaneously suffering from monoclonal gammopathy of undetermined significance (IgGλ). Urine Bence-Jones protein was negative. During the course, plasma cells accounted for 21.6% of the bone marrow. Based on these clinical features in our case, the second disease was diagnosed as multiple myeloma (MM). Both ITP and MM were successfully treated with corticosteroids, bortezomib, lenalidomide with dexamethasone and eltrombopag olamine...

A 63-year-old man with Bence Jones-κ multiple myeloma (MM) presented with renal impairment. First, we administered a bortezomib-containing regimen which is considered to be the first choice among therapeutic approaches for MM patients with renal failure. However, his condition was refractory to bortezomib, and the renal dysfunction worsened (creatinine 12.55mg/dl) necessitating the initiation of hemodialysis. Subsequently, we administered an adjusted dose of lenalidomide and dexamethasone. Dialysis could be discontinued after 3 cycles of lenalidomide therapy...

The diagnosis of smoldering multiple myeloma (SMM) includes patients with a heterogeneous risk of progression to active multiple myeloma (MM): some patients will never progress, whereas others will have a high risk of progression within the first 2 years. Therefore, it is important to improve risk assessment at diagnosis. We conducted a retrospective study in a large cohort of SMM patients, in order to investigate the role of Bence Jones (BJ) proteinuria at diagnosis in the progression to active MM. We found that SMM patients presenting with BJ proteinuria had a significantly shorter median time to progression (TTP) to MM compared with patients without BJ proteinuria (22 vs 88 months, respectively; hazard ratio=2...
