[A case of vascular leiomyosarcoma of the superficial soft tissues]

The authors report a case of vascular leiomyosarcoma of the superficial soft tissues, and point out its epidemiologic (rareness of the report), biologic (high degree of malignancy, trend to local relapse and remote conversion into metastases), histopathologic aspects. They consider significant as to prognostic value the appraisal of the "mitotic index" and the opportunity of a radical intervention, followed by radiotherapy. They, moreover, think it useful, in consideration of the frequency of the relapses, to perform a periodic checking of the patient.
