RESUMO
We document a case of a 24-year-old gravida 2, para 1 (1001), on her second trimester, who was referred to the surgical oncology service for a palpable right hemiabdominal mass. She previously underwent wide excision of a retroperitoneal atypical lipomatous tumour 2 years ago. Her current case was successfully managed by a multidisciplinary team of doctors from the preoperative phase, the actual surgery up to the adjuvant treatment. She had a two-staged surgery: an elective lower-segment caesarean section at 34 weeks age of gestation for which she delivered a healthy baby girl and, 2 weeks after, she had excision of the huge retroperitoneal tumour recurrence. Histopathology revealed a 35 cm×25 cm×22 cm dedifferentiated liposarcoma, for which she was started on adjuvant systemic chemotherapy.
