[Epidural extraskeletal Ewing's sarcoma simulating a herniated disk. Clinical case].

One of the rarest case of primary epidural neoplasm is a soft tissue sarcoma histologically similar to Ewing's sarcoma of the bone. In literature have been described only eleven cases of such extraskeletal Ewing's sarcoma. The authors report an additional case presenting as a disc protrusion in a young male. The Authors include some diagnostic, prognostic and nosologic remarks of this affection.
