Follicular dendritic cells (FDCs) were hyperplastic in lymphoid follicle with small germinal center. The follicle was surrounded by mantle cells (so-called onion skin). The interfollicular regions were expanded by numerous mature plasma cells. (B) The follicle was radially penetrated by a sclerotic blood vessel together with proliferated FDCs, presenting a lollipop-shaped structure. There were plaques distributed in mature plasma cells with abundant red-staining cytoplasm and spoke-like nuclei.
