[Morphology of retinoblastoma and the age of the patient].
A comparative histopathological analysis of 28 retinoblastomas was carried out in children of different age groups. The tumors in children under 1 year of age showed the fewest malignancy features and numerous Flexner-Wintersteiner's rosettes. In patients above 3 years of age particularly numerous pseudorosettes were seen.
