Abstract:
Objective To explore the differentiated diagnostic value of the morphological changes of follicular dendritic cell (FDC)meshwork between different subtype of lymphoma.Methods CD21 was stained by immunohistochemistry (IHC) method,FDC meshwork pattern was studied in 5 6 cases of various lymphomas(including 8 cases of diffuse large B cell lym-phoma,2 cases of burkitts lymphoma,6 cases of small lymphocytic lymphoma,6 cases of plasmacytoma,3 cases of MALT lymphoma,6 cases of peripheral T cell lymphoma,3 cases of anaplastic large cell lymphoma,8 cases of NK/T cell lympho-ma,4 cases of follicular lymphoma,3 cases of mantle cell lymphoma,3 cases of AITL,2 cases of FDC sarcoma).Results FDC meshwork in the morphological changes of various subtypes of lymphoma could be classified into four patterns:①FDC form a disappeared and disintegrated meshwork,most of the lymphoma FDC meshwork fully or partially destroyed,including diffuse large B cell lymphoma,burkitt lymphoma,small lymphocytic lymphoma,plasmacytoma,peripheral T cell lymphoma, anaplastic large cell lymphoma,NK/T cell lymphoma;②FDC meshtwork existence,even hyperplasia,including follicular lymphoma,mantle cell lymphoma,MALT lymphoma;③FDC meshtwork proliferation,disorder and deformation,such as AI-TL;④Full expression subtype:such as FDC sarcoma.Conclusion The morphologic pattern of the FDC meshwork in lym-phomas of follicular origin was differs according to the lymphoma subtypes,and it has important clinical value in lymphoma differential diagnostic.
