case_images: The core biopsy revealed a normocellular marrow for age with a single, paratrabecular lymphoid aggregate (Figure 1), demonstrating similar immunohistochemical staining pattern to that of the right hilar mass.
case_images: Left conjunctival biopsy with diffuse lymphocytic infiltrate (hematoxylin and eosin stain, 20x).

case_images: The biopsy showed an intact epithelium, prominent lymphatic channels with increased stromal lymphocytes (Figure 2).
case_images: The vast majority of the lymphoid cells in the left conjunctival biopsy are CD3-positive T lymphocytes (immunoperoxidase staining, 40x).
