Solitary Plasmacytoma of Bone
نویسندگان
چکیده
Solitary plasmacytoma (SP), histologically indistinguishable from multiple myeloma (MM), is a kind of malignant tumor characterized by the proliferation of monoclonal plasma cells. SP is an independent subtype of plasmacytoma, including extramedullary plasmacytoma and solitary plasmacytoma of bone (SPB) [1]. Most solitary plasmacytomas progress to MM, and are usually treated in the department of hematology. SPB may involve in any bone, however, it mainly occurs in the axial skeleton, especially in a vertebra. SPB has a high risk of progression to MM, and on magnetic resonance imaging (MRI) examination, at least 25% of patients with an apparent solitary lesion have evidence of disease elsewhere.

Solitary bone plasmacytoma belongs to a group of lymphoproliferative clinical disorders typified by clonal proliferation of plasma cells. Solitary plasmacytoma typically involves a single bone or extramedullary site. It commonly occurs in the vertebrae or thorax, and rarely involves the mandible. The aim of this report is to present a rare case of solitary plasmacytoma of the jaws mimicking per...

Solitary plasmacytoma of bone is a rare malignant tumor mostly involving the axial skeleton. The tumor occurs in middle- aged or elderly people (mean age: 55 years) and has a high risk of progression to multiple myeloma. Radiotherapy is the preferred treatment for this disease. We report a case of recurrent solitary plasmacytoma of the fourth lumbar vertebra in a 35-year-old male. The patient s...

Abstract A solitary plasmacytoma of bone occurs in approximately 2-5% of patients with myeloma. The lesion mostly found in the axial skeleton and have infrequently been reported to arise in the hand, and usually occur in the distal phalanges. We report the interesting case of a 75-year-old man who developed a solitary lytic lesion of the thumb proximal phalanx. This lesion was explo...

Solitary Plasmacytoma of the Skull (SPS) is very rare and only 35 cases have been reported in the English literature. It remains controversial whether a solitary plasmacytoma of the skull is essentially identical with a Solitary Plasmacytoma of Bone (SPB) or not. A solitary plasmacytoma of bone, which includes a solitary plasmacytoma of the skull, is characterized by a radiologically solitary b...
متن کاملSolitary Plasmacytoma of Mandible - Report of 2 Cases
A plasmacytoma is a discrete, solitary mass of neoplastic monoclonal plasma cells in either bone or soft tissue (extramedullary). Solitary plasmacytomas can be divided into 2 groups according to location, plasmacytoma of the skeletal system (SBP) and extramedullary plasmacytoma (EMP) respectively. Less than 5% of patients with a plasma cell dyscrasia present with a single bone (SBP) or extramed...
