Circulating lymphocytes of plasmacytoma-carrying BALB/c mice were found to lose their normal surface immunoglobulins; in their place surface structures characteristic of the specific plasmacytoma globulin were demonstrated by the immunocytoadhesion technique. These changes were experimentally reproduced by the incubation of normal BALB/c lymphocytes with an RNA preparation obtained by hot pheno...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

Primary plasmacytoma of the thyroid is a very rare tumour. We report a case and emphasize the importance of excluding multiple myeloma which may present as an extramedullary plasmacytoma. Histological diagnosis has been simplified by the use of immunohistochemical techniques.

solitary plasmacytoma in the right shoulder in 2002, which was treated with local radiotherapy. In December 2004, new plasmacytomas in the knee and ankle were diagnosed and treated with radiotherapy and chemotherapy, with good clinical response. In November 2007, a new plasmacytoma in the right thigh was diagnosed and systemic treatment was chosen. The patient developed cholestatic jaundice aft...

A case of large bowel pseudo-obstruction due to colonic amyloidosis associated with an intestinal plasmacytoma is described. The association of an intestinal plasmacytoma with massive local amyloid deposition has not to our knowledge been previously reported.

OBJECTIVE To describe the imaging features of pelvic solitary plasmacytoma and to correlate them with the pathologic grade. MATERIALS AND METHODS A retrospective study was performed on the imaging features of 10 patients with a histological diagnosis of pelvic solitary plasmacytoma. The imaging studies were assessed for bone expansion, cortical destruction, signal intensity/density of soft ti...

  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...

BACKGROUND Primary lymph node plasmacytoma is a rare disease that typically involves lymph nodes of the neck. In only 15% of cases is the disease generalized. Here, we present a case of generalized lymph node plasmacytoma in a patient with Sjögren's syndrome with an unusual course. CASE PRESENTATION A 48-year-old white woman presented to our hospital with enlargement of groups of lymph nodes,...

A patient with a 3-month history of headache refractory to pain medication was admitted. The CT scan and MRI showed evidence of a posterior fossa mass. This was pathologically confirmed as an extra medullary plasmacytoma (EMP). He had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. A solitary bone plasmacytoma (SBP) was the cause...
