Dysplastic gangliocytoma of the cerebellum is reported in a newborn. It is characterized by large ganglion cells in the molecular layer and premature attenuation of the external granule-cell layer. The internal granule-cell layer appears rarefied but otherwise normally organized. It appears that in this disease the migrating granule cells mature too early and become arrested in the molecular layer, because of their abnormal forms, while others continue to migrate and grow in size in their normal location in the inner granule-cell layer.
