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 desmoplastic reaction. MIB-1 labelling was rare, despite foci of apparently primitive neuroepithelial cells. There was lacking p53 protein expression by tumour cells in all cases. The prognosis was good following either partial or complete tumour resection. DIGs are a distinct form of developmental neuroepithelial tumour, probably arising from neural progenitor cells in subcortical zone along with mature subpial astrocytes.
Conclusions. In view of its favourable prognosis, this tumour has to be diagnosed accurately by immunohistochemical techniques using glial and neuronal markers. The absence of p53 protein expression suggests that DIG probably has different molecular genetic pathways from other supratentorial astrocytomas.
