Introduction: Plasmacytoma is a monoclonal proliferation of plasma cells. It can be an isolated lesion, for which the term extramedullary plasmacytoma is used, or a representation of multiple myeloma.The upper respiratory tract is the most common site for an extramedullary plasmacytoma. Sinonasal plasmacytomas cause different symptoms depending on the sites of origins and the areas of involveme...

extramedullary hematopoiesis is characterized by the presence of hematopoietic tissue outside the bone marrow. extrathoracic extramedullary hematopoiesis is a rare and usually asymptomatic condition. we report a case of a 38-year-old female with paraspinal and presacral extramedullary hematopoiesis with polycythemia vera. clinical and laboratory evaluation, along with radiological and histopath...

Even in the era of new drugs, multiple myeloma patients with extramedullary relapse have a poor prognosis. Our goal was to analyze the frequency and outcome of extramedullary relapse occurring in relapsed multiple myeloma patients. In total, we analyzed the prognosis of 226 relapsed multiple myeloma patients treated between 2005 and 2008 and evaluated them for presence of extramedullary relapse...

introduction extramedullary hematopoiesis in the kidney and adrenal are rarely reported in medical literature and are usually found as incidentaloma. it usually occurs in patients with hematologic disorder such as thalassemia. case presentation the patient was a 23-year-old iranian man with beta thalassemia who was admitted with a suprarenal mass. adrenal mass was detected by ultrasonography an...

Hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). Their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).However, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. Hereby, authors report a w...

Poor outcome of extramedullary disease in multiple myeloma patients and lack of outcome predictors prompt continued search for new markers of the disease. In this report, we show circulating microRNA distinguishing multiple myeloma patients with extramedullary disease from myeloma patients without such manifestation and from healthy donors. MicroRNA-130a was identified by TaqMan Low Density Arr...

STUDY DESIGN Retrospective case series. PURPOSE To investigate the relationship between tumor location and clinical characteristics. OVERVIEW OF LITERATURE Hemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as intramedullary, intramedullary+extrame...
