[Ewing's sarcoma with primary localization in the skull: apropos of two cases].

Two cases of Ewing's sarcoma primary found in the skull are presented. Both started with neurologic symptoms, the first case with intracraneal hypertension syndrome, and the second case with Jackson-like crisis. We emphasize the rareness of the initial localization, as well as the favorable evolution of both cases after surgery and radiotherapy and chemotherapy treatment.
