(a) High power view shows the tumour cells staining positive for vimentin (IH stain with haematoxylin counterstain ×400 magnification). (b) High power view shows tumour cells are positive for CD138 (IH stain with haematoxylin counterstain ×400 magnification). (c) High power view shows that tumour cells are positive for MUM 1 (IH stain with haematoxylin counterstain ×400 magnification). (d) High power view shows that tumour cells are positive for CD56 (IH stain with haematoxylin counterstain ×400 magnification). (e) High power view shows that tumour cells are positive for kappa light chain (IH stain with haematoxylin counterstain ×400 magnification). (f) High power view shows that tumour cells are negative for Lambda light chain (IH stain with haematoxylin counterstain ×400 magnification). (g) High power view shows the ki67 proliferation index in the tumour (IH stain with haematoxylin counterstain ×400 magnification).
