When only one mass is present, it is known as a plasmacytoma
while more than one is known as multiple myeloma.

is frequently diagnosed with cytology or immunohistochemistry (VAIL, 2013).
6%) patients had collapsed vertebra secondary to plasmacytoma
The percentage of patients with a newly diagnosed plasmacytoma
at the time of presentation was not significantly different between the HIV-positive and HIV-negative groups.
Plasma cell neoplasms encompass plasmacytoma
, plasma cell myeloma (PCM), monoclonal gammopathy of undetermined significance, and monoclonal immunoglobulin deposition diseases; the first 2 are reviewed here.
Fine needle aspiration cytology in extramedullary plasmacytoma
Less likely considerations included an extra-axial hypercellular mass such as meningioma, lymphoma or plasmacytoma
5 years to 65 years (Mean Age=37y) and 1 (M) case was diagnosed as Plasmacytoma
, age 42 years.
Mast cell tumor, cutaneous lymphoma and cutaneous plasmacytoma
were suggested as differential diagnosis.
Positive [sup]18 F-FDG PET results, especially with a maximum standardized uptake value of more than 3, in patients with pulmonary amyloidosis should raise suspicion about associated lymphoma or plasmacytoma
PTLD was classified according to the World Health Organization criteria for early lesions (plasmacytic hyperplasia, infectious mononucleosis), polymorphic lesions, monomorphic lesions (diffuse B-cell lymphoma, Burkitt's lymphoma, plasmacytoma
, plasma cell myeloma, T-cell lymphoma, other) and Hodgkin's lymphoma (10).
