Histopathology of ocular and bone marrow tissue. a Ocular tissue with H&E stain x5. b Ocular tissue with H&E stain x40. c Bone marrow tissue with H&E stain x100. d Bone marrow tissue with synaptophysin stain x100. e Bone marrow tissue with CD56 stain x100. The ocular sections reveal retinoblastoma tumor with poorly differentiated cells with extensive areas of anaplasia. The bone marrow sections reveal tiny groups of small round cells that were positive for CD56 and synaptophysin.
