Solitary plasmacytoma may be considered as a rare neoplasm of head and neck and is a different disease compared to multiple myeloma. The main difference is related to the better clinical prognosis of solitary plasmacytoma, which may be clinically silent for several years but several local recurrences may be possible once diagnosed and treated. Clinical signs and symptoms of solitary plasmacytom...
Renal plasmacytoma is extremely rare, presenting diagnostic challenges due to its unusual location and non-specific or absent symptoms. To the best of our knowledge, only 24 cases of renal plasmacytoma have been reported in the literature. The present study reports a case of primary renal plasmacytoma in a 46-year-old female patient. Computed tomography (CT) revealed that the mass was located i...
INTRODUCTION Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare. AIM This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic. CASE REPORT A 51-year-old woman presented at our tertiary universit...
BACKGROUND Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells outside bone marrow. It accounts for 4% of all non-epithelial sinonasal tumors. According to the literature, radiotherapy is the standard therapy for extramedullary plasmacytoma. However, the conversion rate of extramedullary plasmacytoma to multiple myeloma is reported to be betw...
Multiple myeloma in humans is frequently associated with mast cell infiltration and neovascularization, which correlate directly with disease severity, but the mechanisms underlying this relationship remain unclear. Here, we report that primary murine mast cells express angiopoietin-1 (Ang-1) and low levels of VEGF-A but not Ang-2 and that 2 established murine plasmacytoma cell lines express hi...
The authors report on a study of eight cases of intracranial plasmacytoma to identify the risk of progression to multiple myeloma and suggest the treatment required for cure of solitary lesions. The diagnosis of multiple myeloma or myelomatous changes was made in the immediate postoperative period in four patients (50%), two of whom had skull base lesions. Of the four remaining patients, three ...
These symptoms can include weakness, fatigue, spontaneous bleeding, and increased infection.3 As the disease progresses, hypercalcemia due to increased bone resorption is often seen.3 Commonly, patients can develop kidney involvement, resulting in renal failure.3 In this case, the patient had none of these signs and symptoms when she initially presented with visual complaints. In the literature...
