Retinoblastoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Cellular Classification

Retinoblastoma is composed mainly of undifferentiated anaplastic cells that arise from the retina. Histology shows similarity to neuroblastoma and medulloblastoma, including aggregation around blood vessels, necrosis, calcification, and Flexner-Wintersteiner rosettes. Retinoblastomas are characterized by marked cell proliferation as evidenced by high mitosis counts and extremely high MIB-1 labeling indices.[1]
