cheilitis is a very rare type of lip inflammation of unknown etiology characterized histologically by diffuse plasma cell
infiltration in dermis (27,30).
Monoclonal gammopathy of undetermined significance (MGUS) is a plasma cell
disorder,that occurs in 3% of the population aged more than 50 years, and is the commonest among plasma cell
dyscrasias.1,2 The hallmark of Monoclonal gammopathies is the expansion of a single clone of plasma cells
, which yields a homogeneous monoclonal protein (M-protein/M-component or paraprotein).
We used Plasma Cell
Enrichment Technique for the study which is a path breaking technique available at only a handful of centers in India.
This inclusion was supported by the fact that RT showed elevated numbers of IgG4 positive plasma cells
as well as the morphologic features of IgG4 related disease .
neoplasms of the craniocervical junction (CCJ) are rare.
Meanwhile, histopathology from the earlier right iliac lymph node biopsy revealed sinus histiocytic aggregates interlaced with lymphocytes and plasma cells
(Figure 2(a)), majority of cellular constituents being plasma cells
, characterized by oval cellular contours and eccentrically located nuclei (Figure 2(b)); this was confirmed by diffuse immunoreactivity for CD138 (Figure 2(c)).

[greater than or equal to] 10% or biopsyproven bony or extramedullary plasmacytoma and any one or more of the following signs of end-organ damage that can be attributed to the plasma cell

Differentiation and IgA1 Synthesis.
Amyloidosis of the breast is most commonly immunoglobulin light chain amyloidosis (AL) of idiopathic origin, but may result from plasma cell
dyscrasia or malignancy.
Immunoglobulin G4-related systemic disease (IgG4-RSD) is a recently emerging disorder characterized by swelling lesions with storiform fibrosis and lymphoplasmacytic infiltration enriched with IgG4-positive plasma cells
. IgG4-RSD has been found in multiple organs/tissues.
However, the findings in marrow can be highly variable with plasma cell
percentage often ranging from 30 to 90.
