Neuroblastoma represents the most common and lethal solid tumour of early childhood. In view of variations in genetic elements, MYCN amplification is certainly the most prominent genetic factor occurring in 1/4 or 1/5 of children with neuroblastoma; however, overall, the pathogenesis of neuroblastoma remains to be resolved. Rare, sporadic infections with Epstein-Barr, hepatis C virus and varicella-zoster virus have been detected in children with neuroblastoma, while the presence of BK virus was initially claimed, but later falsified as a triggering factor for the development of high-risk neuroblastoma. The proposed model by Professor Ugo Rovigatti, Professor of Molecular Biology at the University of Florence in Italy, is based upon infection with micro-foci inducing virus and its potential tumorigenic role as trigger of i) high and persistent inflammation; ii) chromothripsis and genetic instability; and iii) in vitro cell transformation and in vivo carcinogenesis.Modelling is still under-utilized and under-developed in clinical virology and cancer research; however, it is expected to play a significant role in the future, aiming to elucidate the cancer enigma. This article is based on a webinar on neuroblastoma in children, which was organised virtually on
