CD70 expression in different subtypes of T-cell lymphomas. (A) Representative images of hematoxylin/eosin (H/E), IHC stains of CD4 and CD70 in 2 skin biopsies of MFs, showing different levels of CD70 expression (original magnification, ×40). (B) Representative images of H/E, IHC stains of CD30 and CD70 in a skin biopsy of a patient with pcALCL (original magnification, ×40). (C) Representative images of H/E, IHC stains of CD4 and CD70 in a lymph node biopsy of PTCL, NOS (original magnification, ×20). (D) Representative images of H/E, IHC stains of CD30 and CD70 in a lymph node biopsy of systemic ALCL (original magnification, ×20). (E) Images of H/E and IHC stain of CD70 in a skin biopsy of herpetic dermatitis, showing negative CD70 expression (original magnification, ×40).
