Secondary lymphoid nodule

This image shows a more fully developed secondary nodule with a large germinal center.   The darkly staining perimeter of the nodule, the mantle, is composed mainly of tightly packed B lymphocytes formed in the germinal center.  The germinal center can be subdivided into an upper light region and a lower dark region.  200x
