a-b Immunostaining for CD8.The sinusoid-like structures are highlighted by CD8 in the splenic hamartoma, in addition to some small lymphocytes (a, × 40; b, × 200). Normal red pulp is shown for comparison (left field) (a, × 40). c Immunostaining for CD31 highlights the lining cells of disorganized sinusoid-like channels and histiocytes (c, × 400). d-e Immunostaining of vimentin is diffusely positive in the lesion (d, × 200; e, × 400). f Immunostaining of SMA is negative (× 400). For all markers, the bizarre stromal cells (arrows, b, c, f) are negative, except for vimentin (arrows, e)
