Besides this, bone marrow biopsy helps in finding cancerous plasma cells
and medical imaging in finding bone lesions.
The total number of IgG4-positive plasma cells
was more than 10/HPF, but the IgG4/IgG ratio was less than 40%.

expressed predominantly IgG (c); of these, the majority (over 60%) were immunoreactive for IgG4 (d) (200x original magnification).
This theory seemingly would require the plasma cell
malignancy to precede the polycythemia.
IFN-[alpha] Treatment Led to More Plasma Cell
Differentiation and IgAl Production from B Cells of Healthy Donors.
On assessing the correlation between plasma cell
morphology and stage according to plasma cell
burden, cross-tabulation suggested significant relation between morphology and stage (Table 3], but statistical significance could not be proven on applying the Chi-square test (p value = 0.804],
No environmental or occupational exposures have been definitively established as causes for any plasma cell
Other differential diagnoses included secondary cutaneous plasmacytoma in the setting of systemic disease, mucosal extramedullary plasmacytoma with secondary skin involvement, marginal zone B-cell lymphoma, plasma cell
granuloma, non-Hodgkin lymphoma, high-grade malignant immunoblastic lymphoma, and poorly differentiated neoplasms, as well as infectious diseases that cause infiltration of plasma cells
