A case of long surviving metastatic retroperitoneal epithelioid sarcoma in a 20 year old male

This is the case of a 20 year-old male who came to our observation with a neoplastic lesion of the retroperitoneum. At diagnosis it had already spread to the lung, the liver and to the retroperitoneal para aortic lymph nodes. The patient was treated only with chemotherapy, first 4 cycles of PEI schedules and the second option were 3 cycles of EI schedule. After the first treatment the disease showed the enlargement of a liver lesion, in the VII segment and the vascular component of it was increased. This same lesion, after the EI administration, colliquated and didn't modify its size. Since the end of the therapy the patient has been followed up every 3 months for the first 3 years and every 6 months from the third year onward; he is now at 5 years from the last treatment with a stable disease.
