title: Management of liposarcoma occurring in pregnant women.
abstract: BACKGROUND
  The coexistence of pregnancy and liposarcoma is rare. Only 12 cases of pregnancy-associated liposarcoma have previously been reported in the English-language literature.
  
  
  METHODS
  We present two cases of liposarcoma occurring in pregnant patients: one myxoid liposarcoma in a 29-year-old woman at 29 weeks' gestation; another well-differentiated liposarcoma in a 44-year-old woman at 22 weeks' gestation.
  
  
  RESULTS
  The first patient's infant was delivered by cesarean section after the confirmation of pulmonary maturity of the fetus. The patient was subsequently treated with chemotherapy and radiotherapy. The second patient awaited delivery until 32 weeks' gestation with no treatment of the tumor because she had a low-grade sarcoma. After cesarean section, surgical treatment followed.
  
  
  CONCLUSIONS
  Treatment of sarcomas occurring during pregnancy is difficult. Both mother and fetus should be appropriately managed, depending on the trimester at the time of diagnosis and the histological type and grade of the tumor.
