Figure 1 Photomicrographs of immunostains for CD3 (A, B, E, and F) and FOXP3 (C, D, G, and H) performed on FFPE tissue sections of skin biopsy specimens before (A and C) and after (B and D) treatment, and colon biopsy specimens before (E and G) and after (F and H) treatment with denileukin diftitox for posttransplantation relapsed T cell lymphoma. The skin and colon biopsy specimens exhibited histopathologic findings consistent with GVHD, with obvious decreases in cutaneous intraepidermal and colonic lamina propria CD3+ and FOXP3+ T cell frequency.
