A rare case of Ewing's sarcoma, originating in the mandible, is reported. The symptomatologic and radiological aspects is often aspecific. For this reason the diagnostic-therapeutic routine is presented and the difficulty of clinical diagnosis is accentuated. In these cases it may be appropriate to make use of immunohistochemical analysis such as the research of markers like the NSE (Neuro-Specific Enolase). This will be useful to reach an accurate preoperative diagnosis and in order to adopt a correct therapeutic protocol.
