Histology and immunohistology of a composite HL and DLBCL. (a, b, c) Overviews (× 5 magnification) of the composite lymphoma, in (a) a hemalaun/eosin (HE), in (b) an anti-CD20 and in (c) an anti-CD3 immunostaining. In the three pictures, the DLBCL is in the upper part and the lower right part, whereas the HL is in the lower left part; (d) × 200 magnification of a HE staining from the HL part. Two HRS cells are marked by arrows; (e) × 200 magnification from a HE staining of the DLBCL; (f) anti-CD30 staining of an HRS cell (× 400); (g) anti-CD15 staining of an HRS cell (× 400); (h) anti-CD20 immunostaining of the DLBCL part (× 200); and (i) of the HL part with a CD20-negative HRS cell (× 400).
