A rare case of primary extramedullary plasmacytoma of the heart is described. The large space-occupying tumor in the atrial wall and its associated significant pericardial effusion caused marked impairment of cardiovascular function. The diagnosis was made via intravenous biopsy. Immunohistochemistry demonstrated CD45 and kappa light chain expression. Other B-cell- and T-cell-specific lymphoid markers were negative. Elevated kappa light chain was detected in serum by immunofixation electrophoresis. The differential diagnosis of plasmacytoma should be considered in cardiac tumors when routine screening is negative with lymphoid (CD20, CD3) and soft tissue immunohistochemical markers.

Background: Carcinosarcoma is a rare and highly aggressive biphasic malignant tumor. To date, no cases of primary intraspinal carcinosarcoma have been reported.
Case Presentation: This study reports a case of a 36-year-old female with primary intra dural extramedullary carcinosarcoma.

Myeloproliferative neoplasm-associated myelofibrosis is a clonal stem cell process characterized by pronounced bone marrow fibrosis associated with extramedullary hematopoiesis and splenomegaly. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) represents the only curative treatment leading to bone marrow fibrosis regression. Here we provide an in-depth skeletal characterization of myelofibrosis patients before and after allo-HSCT utilizing clinical high-resolution imaging, laboratory analyses, and bone biopsy studies.

Background: Metastatic spine tumor surgery (MSTS) is often complex and extensive leading to significant blood loss. Allogeneic blood transfusion (ABT) is the mainstay of blood replenishment but with immune-mediated postoperative complications. Alternative blood management techniques (salvaged blood transfusion [SBT]) allow us to overcome such complications.

Introduction: Myelofibrosis (MF) is often characterized by a multifactorial anemia determined, in part, by bone marrow (BM) fibrosis, extramedullary erythropoiesis and splenomegaly. Ruxolitinib (RUX) is the first-in-class janus kinase 2 (JAK2) inhibitor approved for treatment of MF, proved to reduce spleen volume and decrease symptom burden. The red cell distribution width (RDW) is the measure of erythrocyte volume variability (anisocytosis).

Primary solitary extramedullary plasmacytoma is a malignant neoplasm characterized by the monoclonal proliferation of plasma cells outside the bone marrow. The tumor rarely occurs in the sinonasal tract, accounting for about 4% of all non-epithelial sinonasal tumors. Herein, the authors describe a rare case of sinonasal extramedullary plasmacytoma in a 33-year-old man who presented with a 3-month history of progressively increasing nasal mass, causing obstruction.
