title: [A relationship of congenital brain malformations and tumor growth].
abstract: The peritumor-like areas of 12 cerebral hemispheric tumors were examined. Histological study revealed vascular malformations and/or congenital tissue dysplasias in all cases: cortical disorganization, neuronal heterotopy into the white matter, neural location in the molecular cortical layer, and persistence of a subpial granular cell layer. Immunohistochemical study using Ki-67 antibodies in the peritumor-like tissue dysplasias revealed proliferative activity in a number of cases. The associations of the origin of brain tumors and congenital malformations are discussed.
