[Leiomyosarcoma of the uterus in young identical twins].

The authors describe the occurrence of a confirmed leiomyosarcoma and a tumor suspected of being a leiomyosarcoma in 23-year-old twin sisters. In one of them the tumor had caused clinical symptoms; in the second it was detected at the presymptomatic stage as a result of increased attention after detection of the first tumor. In the first case treatment consisted in an extended abdominal hysterectomy, sparing one ovary, with bilateral interiliac lymph node extirpation; in the second case, in an extended abdominal hysterectomy with both adnexae and bilateral interiliac lymph node extirpation. So far - 13 and 10 months after the initial treatment, respectively - there are no signs of continued tumor growth in either case.
