title: A case of huge retroperitoneal liposarcoma in pregnancy.
abstract: A 39-year-old woman was referred to our hospital at 28+2 week gestation. Routine obstetric examination revealed a palpable pelvic mass. Initial investigation by magnetic resonance imaging demonstrated a huge solid mass with heterogeneous enhancement that completely filled the right side of the abdomen. She underwent two surgeries: a programmed cesarean section by Department of Obstetrics and Gynecology team and a laparotomy performed by the General Surgery team. Final diagnosis was de-differentiated liposarcoma (French Federation Nationale des Centres de Lutte Contre le Cancer grade 2/3). She has been treated with radiation therapy focusing on high risk area of retroperitoneum followed by adjuvant chemotherapy (doxorubicin and ifosfamide). Below is the full case with literature review.
