A 55-year-old lady presented to our clinic with 1 month history of right lower back pain and hematuria. Her history was notable for stage 1B mixed clear cell-endometroid cancer of the uterus status post radical abdominal hysterectomy with adjuvant radiotherapy, 7 years before the current episode. The patient had no evidence of recurrence. Initial noncontrast imaging suggested a 2.5\u2009mm calculus in the distal right ureter and hydronephrosis; however, ureteroscopy revealed a large fleshy mass at the location. Histopathologic evaluation demonstrated the lesion to be primary small cell carcinoma of the ureter, without evidence of it being a derivative of the prior gynecologic malignancy. Metastatic work-up revealed high burden retroperitoneal adenopathy. The patient was started on Cisplatin-based neoadjuvant chemotherapy with plan for nephroureterectomy in the future. At 3 months follow-up, the patient was doing well with significant shrinkage of retroperitoneal adenopathy and no evidence of disease progression.\n                  <\/jats:p>","DOI":"10.1089\/cren.2016.0103","type":"journal-article","created":{"date-parts":[[2016,11,4]],"date-time":"2016-11-04T15:39:15Z","timestamp":1478273955000},"page":"204-208","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Neuroendocrine Tumor of the Ureter: A Zebra Among Horses"],"prefix":"10.1177","volume":"2","author":[{"given":"Akshay","family":"Sood","sequence":"first","affiliation":[{"name":"Vattikuti Urology Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean R.","family":"Williamson","sequence":"additional","affiliation":[{"name":"Henry Ford Health System"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Leavitt","sequence":"additional","affiliation":[{"name":"Vattikuti Urology Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,11,1]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1994.tb17251.x"},{"key":"e_1_3_2_3_2","doi-asserted-by":"crossref","first-page":"1464","DOI":"10.1111\/j.1464-410X.2009.08451.x","article-title":"Neuroendocrine tumours of the urinary system and male genital organs: Clinical significance","volume":"103","author":"Mazzucchelli R","year":"2009","unstructured":"Mazzucchelli R, , Morichetti D, , Lopez-Beltran A, et al.
