[Extraskeletal Ewing's sarcoma].

5 patients diagnosed as having extraskeletal Ewing's sarcoma have been referred to our adult oncology unit since 1980. All were men, ranging in age from 18-57 (mean 32 years). The primary tumor was located on the trunk in 4 and in an extremity in 1. Wide tumor excision was feasible in only 2. 3 died within 27 months and 2 are alive, 13 and 67 months, respectively, following diagnosis. This study demonstrates the highly aggressive nature of extraskeletal Ewing's sarcoma and the need for early diagnosis and efficient chemotherapy.
