[Jadassohn's nevus sebaceous: E.E.G. data of four cases (author's transl)].

Electroencephalographic data of four cases of Jadassohn's nevus sebaceous found in children is reported. An attempt has been made to establish a correlation between the region of cutaneous lesion with that of the electroencephalographically affected area of the cerebral hemisphere. Cases published up until 1975 that have made reference to electroencephalographic findings are reviewed.
