Organ-confined primitive neuroectodermal tumor arising from the kidney.J Pediatr Surg. 2003 Apr; 38(4):619-21.JP
Primitive neuroectodermal tumor (PNET) of the kidney is a rare entity with high malignant potential. Of the reported cases of renal PNET, patients presented with metastatic disease and had a poor response to therapy. The authors describe a rare case of an organ-confined primary PNET arising from the kidney in a 16-year-old girl who presented with vague abdominal pain. Tumor behavior and treatment modalities are discussed.
