Among the small round cell renal tumors is Ewing's sarcoma, also called primitive peripheral neuroectodermal tumor, which is a rare entity with an extremely aggressive clinical course.
Primary renal sarcomas are rare tumors that occur in children and young adults, at a mean age of 28 years and with a slightly higher predominance in men, about 100 cases have been reported in the literature.
Patients remain asymptomatic until the tumor reaches large size, the most common symptoms of which include abdominal/flank pain, palpable mass, hematuria.
Systemic symptoms include: weight loss, and fever; the prognosis is poor with low overall survival.
Its tendency is extremely aggressive and is characterized by early metastasis in 25-50% of cases with lung, liver and bone metastases.
