Abstract
Other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OI-LPD) have been reported as one of the adverse effects of immunosuppressive therapy. The aim of this study was to describe the clinicopathologic and immunohistochemical features of OI-LPD in the oral cavity. Immunohistochemistry was performed to describe the immunohistochemical features in our 4 cases. The results were analyzed along with 62 cases of oral OI-LPD in the English and Japanese literature to define clinical and pathologic characteristic features. In our immunohistochemical analysis, Epstein-Barr virus (EBV)-positive OI-LPD showed a higher percentage of mouse double minute 2-positive cells than EBV-negative samples. A literature survey revealed that OI-LPD (including the present cases) arises primarily in the gingiva, followed by the tongue, and usually occurs with a male-to-female ratio of 1:1.9. The rate of EBV positivity was 93.8%. Further, 31 of 66 patients had osteonecrosis of the jaw and 24 of 31 patients had taken multiple immunosuppressive drugs in combination. We can therefore conclude that the overexpression of mouse double minute 2 in OI-LPD is associated with EBV infection, and the combination of multiple immunosuppressive drugs may be a risk factor for osteonecrosis of the jaw.
