[Histopathologic differentiation of tumors derived from neuroblastic cells in children depending on age].
The histopathology of 224 tumours of neuroblastic origin was analysed in relation to the age of patients. Maturing neuroblastomas (NBS) dominated in infants, where as in the most numerous group of children 1-5 years of age, prevalence of neuroblastomas without any signs of maturation was noted. In children over 5 years of age a high incidence of tumours with evident maturation was noted (ganglioneuroblastomas and ganglioneuromas). The prevalence of maturing neuroblastomas in infants correlate well with an advantageous clinical course of neuroblastomas at this age.
