Figure 2

(a) Histopathologic exam of the small bowel revealed the diagnosis of IVLBCL with intravascular large atypical cells, H&E stain, 20x magnification. (b) Placenta also showed involvement of the disc (maternal blood) by IVLBCL including large atypical cells, H&E stain, 20x magnification. (c, d). Small atypical cells were seen in the small blood vessels of the breast, highlighted by CD20, H&E, and immunohistochemistry stains, 40x magnification. (e, f) Small lymphoma cells involving breast in comparison with large cells involving placenta, H&E stains, 60x magnification.
