title: [Primitive neuroectodermal tumor. Ewing's sarcoma].
abstract: Primitive neuroectodermal tumor is an extraordinarily rare primary tumor in the kidney and can be mistaken for a variety of other round cell tumors. It is important to recognize each of these entities, because each carries unique therapeutic and prognostic implications. However, accurate diagnosis of these tumors is hindered by their significant morphologic overlap and complicated by their rarity. These neplasm are highly aggressive that tend to recurence and to metastatize. Standard therapy combining surgery, chemotherapy, radiation and genetic therapy. We report a case of primitive neuroectodermal tumor of the kidney in a 50 year old female patient.
