We read with interest Deng et al.'s recent manuscript concerning a newly molecularly defined glioneuronal CNS tumour entity, termed diffuse glioneuronal tumour with oligodendroglioma-like features and nuclear clusters (DGONC)(1). DGONCs were identified by a distinctive methylation profile that segregated away from previously recognised molecular groups of CNS tumours. On further review, the authors describe DGONCs as a novel glioneuronal tumour with key neuropathological features including oligodendroglioma-like perinuclear halos and nuclear clusters.
