Abstract

Primitive neuroectodermal tumors (PNETs) are primitive neuroblastic tumors that, unlike neuroblastomas, arise outside the autonomic nervous system, but very few cases with a renal origin have been described. The immunohistochemical staining for CD99 is useful in their diagnosis. A case of renal primitive neuroectodermal tumor, in a 61- year-old man presenting with a painless gross hematuria is reported. The immunohistochemical staining of the renal mass was strongly positive for CD99.
