Plasma cell neoplasms

Aharon M Feldman, Ziying Zhang, Thomas Buekers, Mohamed A Elshaikh
In contrast to multiple myeloma (MM) which exhibits diffuse bone marrow and other organ involvement, solitary plasmacytomas carry a favourable prognosis. Extramedullary plasmacytomas (EMP) are a unique form of plasma cell neoplasms. These tumours are rare in the female reproductive tract. Only 24 cases of gynaecologic plasmacytomas were reported to date (7 cases were solitary plasmacytomas and 17 cases were either part of disseminated MM with involvement of a gynaecologic organ or were lacking complete work-up to rule out MM)...

Endometritis is nowadays rare in developed countries and typically shows a subclinical or mild course; therefore, there are probably more cases of endometritis than diagnosed but they lack clinical relevance. In the fertile period of life it can be the reason for vaginal bleeding and infertility. The most common causes for non-specific endometritis are residual placental tissue after abortion or childbirth, intrauterine interventions, lesions within the uterine cavity, such as endometrial polyps, endometrial hyperplasia and neoplasms, intrauterine devices (IUD) and cervical stenosis...

An inflammatory myofibroblastic tumor (IMT) is a distinctive neoplasm composed of myofibroblastic and fibroblastic spindle cells, accompanied by inflammatory infiltration of plasma cells, lymphocytes, and eosinophils. IMTs rarely occur in the urinary bladder. It is important to distinguish this tumor from other malignant spindle cell tumors. Herein, we report a patient with an IMT showing muscle invasion, who underwent a transurethral resection of the bladder tumor and, at a later date, partial cystectomy. The resected tumor specimen revealed a proliferation of spindle-shaped cells on a background of plasma cells and lymphocytes...

Neutrophil gelatinase-associated lipocalin, known also as 24p3 lipocalin, lipocalin-2 or uterocalin (in mouse), is a small secretory protein binding small molecular weight ligands which takes part in numerous processes including apoptosis induction in leukocytes, iron transport, smell, and prostaglandins and retinol transport [19]. It was discovered in activated neutrophils as a covalent peptide associated with human gelatinase neutrophils [7]. Neutrophil lipocalin is secreted physiologically in the digestive system, respiratory tract, renal tubular cells, liver or immunity system...

Plasmablastic lymphoma is an uncommon aggressive non-Hodgkin B-cell lymphoma type defined as a high-grade large B-cell neoplasm with plasma cell phenotype. Genetic alterations in MYC have been found in a proportion (~60%) of plasmablastic lymphoma cases and lead to MYC-protein overexpression. Here, we performed a genetic and expression profile of 36 plasmablastic lymphoma cases and demonstrate that MYC overexpression is not restricted to MYC-translocated (46%) or MYC-amplified cases (11%). Furthermore, we demonstrate that recurrent somatic mutations in PRDM1 are found in 50% of plasmablastic lymphoma cases (8 of 16 cases evaluated)...

The insulin-like growth factor (IGF) signaling system plays key roles in the establishment and progression of different types of cancer. In agreement with this idea, substantial evidence has shown that the type I IGF receptor (IGF-IR) and its primary ligand IGF-I are important for maintaining the survival of malignant cells of hematopoietic origin. In this review, we discuss current understanding of the role of IGF-IR signaling in cancer with a focus on the hematological neoplasms. We also address the emergence of IGF-IR as a potential therapeutic target for the treatment of different types of cancer including plasma cell myeloma, leukemia, and lymphoma...

Plasma cell neoplasms are characterized by a neoplastic plasma cell lineage which produces a monoclonal immunoglobulin. These neoplasms can present as a single lesion (solitary plasmacytoma) or as multiple lesions (multiple myeloma). Solitary plasmacytomas most frequently occur in bone (plasmacytomas of bone), but can also be found outside bone in soft tissues (extramedullary plasmacytomas).

BACKGROUND: Aberrant DNA methylation is considered a crucial mechanism in the pathogenesis of monoclonal gammopathies. We aimed to investigate the contribution of hypermethylation of 4 tumor suppressor genes to the multistep process of myelomagenesis. METHODS: The methylation status of p15, p16, p53, and DAPK genes was evaluated in bone marrow samples from 94 patients at diagnosis: monoclonal gammopathy of uncertain significance (MGUS) (n = 48), smoldering multiple myeloma (SMM) (n = 8) and symptomatic multiple myeloma (MM) (n = 38), and from 8 healthy controls by methylation-specific polymerase chain reaction analysis...

Castleman disease is a complex lymphoproliferative disease pathologically divided into two subtypes, the hyaline vascular variant (HVV) and the plasma cell variant (PCV). The HVV is the most common, is thought to represent a benign neoplasm of lymph node stromal cells, and is treated with surgical resection. It is most commonly found in the mediastinum, where it classically appears as a unicentric, avidly enhancing mass at computed tomography (CT) and magnetic resonance imaging. This appearance can mimic other avidly enhancing mediastinal masses, and location, clinical history, laboratory data, and nuclear medicine single photon emission CT (SPECT) and positron emission tomography (PET) studies can help narrow the differential diagnosis...

Multiple myeloma (MM) is an incurable plasma cell neoplasm with an incidence of 100 patients per year in Singapore. Major advances have been made in the diagnosis, risk stratification and treatment of MM in the recent past. The reclassification of a subset of patients with smouldering MM, based on high-risk biomarkers, and the development of the revised international staging system are among the key new developments in diagnosis and staging. The use of novel agent-based treatment has resulted in significant improvements in the survival and quality of life of many patients with MM...

a) Objective: An increase in cell-free DNA was observed in the plasma of many cancer patients. This major biomarker can be used to differentiate patients with malignant neoplasms from those with benign neoplasms or healthy patients. Depending on the characteristic of the tumor, there are qualitative variations in the circulating cell-free DNA. Today, studies on the concentration of fragments of circulating cell-free DNA and their respective sizes in patients with bladder cancer are not plentiful in the literature...

Pancreatic cancer is one of the most lethal tumors, and reliable detection of early-stage pancreatic cancer and risk diseases for pancreatic cancer is essential to improve the prognosis. As 260 genes were previously reported to be upregulated in invasive ductal adenocarcinoma of pancreas (IDACP) cells, quantification of the corresponding proteins in plasma might be useful for IDACP diagnosis. Therefore, the purpose of the present study was to identify plasma biomarkers for early detection of IDACP by using two proteomics strategies: antibody-based proteomics and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomics...

INTRODUCTION: Cytopenia is a common hematologic finding in patients with HCV infection. Only a few studies have addressed bone marrow (BM) morphologic findings in these patients. No systemic study has been performed in these patients with liver transplantation (LT). METHODS: We retrospectively examined BMs in 49 hepatitis C patients with and without prior LT (n = 19 and n = 30). RESULTS: Among the patients with an available complete blood count (n = 46), the majority of them presented with cytopenia involving one or multiple cell lineages including unicytopenia (13%, n = 6), bicytopenia (31%, n = 14), and pancytopenia (43%, n = 20)...
