Primary Renal Ewing Sarcoma in an Adult

摘要

Primary renal Ewing sarcoma is extremely rare and carries a dismal prognosis. It is particularly diagnostically challenging due to its ability to mimic other round cell tumors. Herein we report such a case in a 28-year-old white female. The diagnosis was confirmed by immunophenotyping, fluorescence in situ hybridization, and reverse transcription polymerase chain reaction analyses. UROLOGY 99: e11-e13, 2017. (C) 2016 Elsevier Inc.
