RESUMO
Retroperitoneal liposarcoma is rare in pregnancy. Management of recurrent disease following surgical resection remained a challenge especially when it is associated with pregnancy. A 30-year old primigravida conceived spontaneously four months following a second laparotomy for resection of recurrent RPLS. The primary surgery was performed four years earlier with optimum postoperative course in the absence of need for postoperative adjuvant treatment Histology of the recurrent tumor confirmed a well differentiated liposarcoma. She was monitored closely for any worsening of symptoms and underwent a MRI and an ultrasound at 12 and 22 weeks gestation respectively. The pregnancy continues to be uneventful and she safely delivered vaginally at 41 weeks gestation. Small RPLS during pregnancy do not pose great obstetrics management challenges. Early detection with multidisciplmary team management would anticipate possible complications to ensure both maternal and fetal wellbeing
