Quantification of bone marrow plasma cells in multiple myeloma patients using conventional morphology is of limited prognostic value, while the merit of multiparameter flow cytometry immunophenotyping is still considered unproven. Here we compare the bone marrow plasma cell counts obtained by morphology and multiparameter flow cytometry and explore the potential prognostic impact of both techni...
The authors present a rare case of plasmacytoma of the orbit involving lacrimal gland with secondary transformation into multiple myeloma in a 42-year-old woman. The lesion was surgically removed and analyzed. Histopathological examination with immunostaining revealed it to be positive for immunoglobulin G and Kappa chains, demonstrating monoclonality. However, no abnormality was observed on se...
We present a 63-year-old male patient with intractable bone pain and rapidly progressive osteoporosis, who was diagnosed multiple myeloma (MM) by CT despite normal magnetic resonance imaging (MRI) findings. The gold standard diagnostic modality for MM is MRI as it can be used to sensitively evaluate marrow, however, the current case highlights that not always accurate in evaluating MM. combinat...
Myelomatous involvement of pleural effusions developing in patients with multiple myeloma is extremely rare and only a few cases have been reported so far. It is thought to represent an aggressive clinical progression of disease and is usually associated with severe complications, poor prognosis and high mortality. Ferritin is a marker of inflammatory pathways that plays a significant role in p...
Plasma cell myeloma with lymphoplasmacytic morphology and cyclin D1 expression, an uncommon variant.
The genetic complexity of multiple myeloma is due in part to the accumulation of mutations, with primary and secondary events. One such secondary event is the development of a gene mutation that may result in overexpression of cyclin D1. The pathway involving cyclin D1 is intricately involved in cell cycle regulation from the G1 to S phase, and alterations may contribute to tumorigenesis. We pr...
Multiple myeloma is a common disease that universally involves the skeletal system. Although rib involvement may occur, the development of pathological flail chest is rare. We describe the treatment and course of this condition in an elderly female, and the use of the bilevel positive airway pressure (BiPAP) ventilatory system in providing pneumatic stabilization, while definitive chemotherapy ...
Background. Some patients who are stable or in remission from a myeloma secreting intact monoclonal immunoglobulin (+/- associated free light-chains (FLCs)) relapse with production of FLC. This FLC escape is one of the illustrations of the intraclonal heterogeneity of multiple myeloma. Results. We report FLC escape in a patient with IgD myeloma characterized by a severe outcome. We discuss para...
objective: multiple myeloma (mm) is a plasma cell malignancy where plasma cells are increased in the bone marrow (bm) and usually do not enter peripheral blood, but produce harmful factors creating problems in these patients (e.g. malignant plasma cells over activate osteoclasts and inhibit osteoblasts with factors like rankl and dkk). these factors are a main cause of bone lesion in mm patient...
The purpose of this study is to identify prognostic markers and treatment targets using a clinically certified sequencing panel in multiple myeloma. We performed targeted sequencing of 578 individuals with plasma cell neoplasms using the FoundationOne Heme panel and identified clinically relevant abnormalities and novel prognostic markers. Mutational burden was associated with maf and prolifera...
