Carcinosarcomas of the urinary tract are exceedingly rare. We report a unique case of a carcinosarcoma of the ureter with a chondrosarcoma and small cell tumor component arising in a 68-year-old male who presented with microscopic hematuria. CT intravenous pyelogram revealed right-sided hydroureter and hydronephrosis with thickening and narrowing of the right ureter. The patient underwent robot-assisted ureterectomy with bladder cuff excision and subsequent adjuvant chemotherapy. The patient is disease-free at 32 months after treatment. We provide a brief synoptic review of carcinosarcoma of the ureter and bladder with utilization of immunohistochemical (IHC) stains and potential diagnostic pitfalls.<\/jats:p>","DOI":"10.1155\/2014\/391615","type":"journal-article","created":{"date-parts":[[2014,12,24]],"date-time":"2014-12-24T21:02:37Z","timestamp":1419454957000},"page":"1-4","source":"Crossref","is-referenced-by-count":1,"title":["Carcinosarcoma of the Ureter with a Small Cell Component: Report of a Rare Pathologic Entity and Potential for Diagnostic Error on Biopsy"],"prefix":"10.1155","volume":"2014","author":[{"given":"Kent","family":"Newsom","sequence":"first","affiliation":[{"name":"Department of Pathology, Immunology and Laboratory Medicine, University of Florida College of Medicine, P.O.
