Surgical treatment of retrosternal extraosseous Ewing Sarcoma in a 6-years old female: A clamshell approach with hemysternectomy and application of a non-crosslinked extracellular matrix
Background Ewing Sarcoma (ES) and Neuroblastoma (NB) belong to a family of tumours of primitive neuroectodermal origin (PNET) that occurs in both bone and soft tissue. Notwithstanding ES and NB are two distinct malignant tumours, sometimes there could be a link between them. Case report We describe a case of an extraosseous ES localized in the retrosternal region and the upper lobe of the right lung, which had been previously treated for NB in a 6 years old female. We treated this case with a clamshell approach which allows, in a one-step surgery, a complete excision of the mass reconstructing the hemysternectomy with a non-crosslinked matrix. Conclusion the clamshell approach is therefore useful to achieve the retrosternal space and the lung with a single surgical access. According to our experience, we consider appropriate to use a non-crosslinked matrix for sternal reconstruction. Highlights ? Ewing Sarcoma (ES) and Neuroblastoma (NB) two distinct malignant tumours, and sometimes there could be a link between them. ? A clamshell approach presents some advantages because we can explore the lung without changing the patients’ position. ? The reconstruction of the sternum has been done by the application of a non-crosslinked extracellular matrix.
