There is growing evidence that children, adolescents, and young adults (CAYA) with B-cell NHL display unique clinical and epidemiologic characteristics. This may be explained by distinct age-related developmental plasticity, immune and haematopoietic repertoires, environmental exposures and social determinants of health, and germline or acquired genetic and molecular features, including those associated with inborn errors of immunity (IEI). Here, we discuss the unique clinical and biological characteristics of several distinct paediatric B-cell NHL types to indicate a path forward in classification of these CAYA NHL to optimally support multidisciplinary patient care and personalized treatment.
