Immunohistologic analysis of DCs and GLs in patients with CD3⁺ and CD3^- LDGL. Immunoperoxidase staining for CD56 and CD57 (red) and CD1a and CD83 (black) in bone marrow biopsies from control and representative patients with CD3^- and CD3⁺ with LDGL. An evident contact between the 2 cell types can be seen in patients with LDGL indicated by arrows. However, GLs and DCs were clearly separated in healthy control subjects (left).
