摘要: Abstract Case reports. Four cases of desmoplastic infantile ganglioglioma (DIG) seen in India are described. These patients presented with large, supratentorial, superficially situated cystic tumours that showed glial and ganglionic differentiation; accompanied by a severe reaction. MIB-1 labelling was rare, despite foci apparently primitive neuroepithelial cells. There lacking p53 protein expression tumour cells all cases. The prognosis good following either partial or complete resection. DIGs distinct form developmental tumour, probably arising from neural progenitor subcortical zone along mature subpial astrocytes. Conclusions. In view its favourable prognosis, this has to be diagnosed accurately immunohistochemical techniques using neuronal markers. absence suggests DIG different molecular genetic pathways other supratentorial astrocytomas.
