title: Rare Renal Incidentaloma in Pregnancy: An Unusual Primitive Neuroectodermal Tumor Presentation.
abstract: Peripheral Primitive Neuroectodermal Tumors (PNETs) are rare lesions that arise from outside the central nervous system and normally do not affect the genitourinary system. Primary renal presentations are extremely rare but given their aggressive behavior and characteristic cytomorphologic and genetic features should be considered well-defined distinct clinical entities in order to distinguish them from other primary tumors featuring round cells in the kidney. We report one case of PNET involving the kidney and associated with pregnancy.
