Immediate chest wall reconstruction during pregnancy: Surgical management after extended surgical resection due to primary sarcoma of the breast

SummaryBackgroundBreast sarcoma during pregnancy is an extremely rare event and represents a complex problem because of a more advanced stage at presentation.MethodThis report presents the first case of a 24-year-old woman with a gestational age of 20 weeks with a fast growing tumour in her left breast (29 × 19 × 15 cm) and infiltrating the skin/pectoralis muscles. Radical mastectomy was performed with a gestational age of 22 weeks and a different design was planned for the latissimus dorsi musculocutaneous flap (LDMF) with primary closure in the V–Y pattern.ResultSatisfactory chest wall coverage and contour were achieved. Final histopathological findings allowed a diagnosis of undifferentiated sarcoma. With a gestational age of 37 weeks, a healthy infant was delivered by means of a caesarean section. The patient is currently in the second postoperative year and no recurrence has been observed.ConclusionManagement of a large breast sarcoma in a pregnant patient presents unique challenges in consideration of the potential risks to the foetus and the possible maternal benefit. The results of this study demonstrate that the VY-LDMF is a reliable technique and should be considered in cases of immediate large thoracic wound reconstruction.
