2023年1月17日 · CD10 in diffuse large B cell lymphoma is a marker for germinal center phenotype (also HGAL, BCL6, CD38, LMO2), generally considered a favorable prognostic factor, secondary in part to association with cell of origin classification (germinal center B cell versus activated B cell) (Mod Pathol 2005;18:1113, J Hematop 2009;2:187)
Pathology Outlines - Programmed death-1 (PD-1)
2021年8月23日 · Comment: CD20 highlights large atypical B cells within small B cell rich nodules. CD3 is positive in background small T cells with occasional CD3 positive T cell rosettes around the large atypical B cells. A PD-1 stain shows T cell rosettes encircling the large atypical B cells in the nodular areas.
