extramedullary plasmacytomas are plasma cell tumors that arise outside the bone marrow. they are most often located in the head and neck. extramedullary plasmacytomas account for approximately 3 percent of plasma cell malignancies. the diagnosis of an extramedullary plasmacytoma depends upon the demonstration of a monoclonal plasma cell tumor at an extramedullary site with no evidence of multip...
Multiple myeloma is a monoclonal malignant proliferation of plasma cells that causes osteolytic lesions in the vertebrae, ribs, pelvic bone, skull and jaw. We report a case of a 66 year-old-woman with pain and right facial swelling. Radiographic examination showed a well-defined radiolucent lesion in left posterior mandible. An incisional biopsy was performed and histopathological examination r...

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...
Background and purpose: Autologous hematopoietic stem cell transplantation may be one of the best treatment options for some patients with hematological malignancies. The process of stem cell homing in the bone marrow and the production and proliferation of denovo cell populations is called engraftment and could be considered as one of the key factors in the success of stem cell transplantation...
Introduction: Following the first description of multiple myeloma (MM), as the second most prevalent hematologic malignancy, multiple promising advances have paved the way to increase the long-lasting complete remission for patients. In the era of the novel therapeutic approaches, the cloning of the apoptosis-inducing genes into the genome of malignant cells has attracted tremendous attention. ...
Background: CD93 has originally been known as a C1q receptor, and many studies have demonstrated that CD93 is expressed on hematopoietic stem cells, B cell progenitors, myeloid and monocytic cells. Moreover, CD93 is shown to be expressed on long-lived plasma cells, and CD93 deficient-mice display an impairment in plasma cell development. Objective: To investiga...
Background: Multiple myeloma (MM) is a plasma cell disorder characterized by presence of monoclonal protein in serum or urine or both, increased bone marrow plasma cells, osteolytic lesion, hypercalcemia, and anemia. Several combination regimens are commonly recommended for treatment of multiple myeloma. The present study aimed at determining the characteristics and outcomes of patients with mu...

پلاسماسیتوم خارج استخوانی یک تومور منفرد نادر بافت نرم است که از تکثیر منوکلونال بدخیم پلاسماسل‌های تغییر یافته ایجاد می‌شود. اگرچه ارتباط نزدیکی با میلوم متعدد دارد، اما پیش‌آگهی بهتری نسبت به آن دارد. این تومور با جراحی یا رادیوتراپی موضعی قابل ریشه کن شدن است. این گزارش یک مورد نادر از پلاسماسیتوم منفرد سینوس ماگزیلاری چپ می‌باشد که تحت عمل جراحی قرار گرفته است و با رنگ آمیزی ایمونوهیستوشی...
