case_images: Biopsies from the polypoid mass of the ileum-cecum valve and the lytic lesion of the left humerus (Figure 1) revealed infiltration by neoplastic cells with plasmablastic traits and expression of CD38, CD138, MUM-1/IRF4, CD79a, and CD30.
case_images: Bone marrow biopsy with limited interstitial infiltration by CLL. The neoplastic cells were small and round (a) (H&E staining, magnification x200) expressing CD20 (b), CD5 (c), and CD23 (d) (DAB, magnification x200).
