Plasma cell granuloma : ウィキペディア英語版 | Plasma cell granuloma Plasma cell granuloma is a lesional pattern of inflammatory pseudotumour, different from the "inflammatory myofibroblastic tumor" pattern. It is linked to IgG4-related disease. == Pathology == Histologically, the lesions consisted of a proliferation of mature plasma cells and reticulo-endothelial cells supported by a stroma of granulation tissue, with varying degrees of myxoid change or collagenization. Angioinvasion within the lesion is observed in 50% of cases. Immunohistochemical staining reveals the IgG-predominant polyclonal nature of the plasma cells, indicating a reactive inflammatory process rather than a neoplastic one. Electron microscopy confirms the benign nature of the plasma cells with fibroblast and myofibroblast proliferation admixed with that of other inflammatory cells.
