Fundus (a) and cell block (b-f) findings in a representative case of vitreoretinal lymphoma (Case 1, R). The fundus reveals dense diffuse vitreous opacity (a). HE staining demonstrates high cellularity of the collected cells with a high nuclear/cytoplasmic ratio and atypical nuclei, and hyper-chromatic cells (b). Immunocytochemically, the atypical lymphoid cells are positive for leukocyte common antigen (LCA) (c) and CD20 (d). Atypical lymphoid cells are negative for CD3 (e). Nuclear immunoreactivity for Ki67 is detected in the lymphoma cells (f)
