Primitive neuroectodermal peripheral tumour of the retroperitoneum

Retroperitoneal primitive neuroectodermal tumour is an uncommon disease. The main treatment consists of surgical resection, which can require resection of great vessels, depending on the location. We present a single case of a 19-year-old male with a large tumour. To achieve R0 resection we needed to remove the vena cava. Venous flow reconstruction was performed with a cava prosthesis.
