Typical histopathologic features of IgG4-RD include marked lymphocytic and plasmacyte infiltration with high percentage of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis [13].
On histology, IgG4-RH is essentially similar to lymphocytic hypophysitis, which is the most prevalent type of primary hypophysitis, besides massive IgG4-positive plasmacyte infiltration [2].
For the plasmacytic cell series they recommended the terms "plasmablast," "proplasmacyte" and "plasmacyte" identify these cells, and they proposed that the term "plasma cell" be avoided; however, both terms, plasmacyte and plasma cell, are still used interchangeably.
The diagnostic criteria for IgG4-RD are as follows (4): 1) distinct changes in target organs; 2) a serum IgG4 concentration >135 mg/dL; and 3) lymphocytes and IgG4-positive plasma cell infiltration and fibrosis upon histopathologic examination, with a ratio of IgG4-positive/IgG-positive plasmacytes >40%, and >10% IgG4-positive plasmacytes/high-power field.
