Figure 3 Histological sections of hepatoduodenal ligament lymph nodes (× 200 magnification). A: The lymphoid follicles contain a reactive germinal center with hematoxylin and eosin staining. No evidences of granuloma or necrosis are visible; B: CD3 (T-cell marker) is positive in the interfollicular areas; C: CD10 (a marker of B-cell activation) is positive in the center of the follicles; D: CD20 (B-cell marker) is observed in the nodules; E: Kappa chain; F: Lambda chain. Neither the kappa nor the lambda chains predominate.
