RT Journal Article SR Electronic T1 Incidental finding of a small cell neuroendocrine carcinoma of the ureter JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e229290 DO 10.1136/bcr-2019-229290 VO 12 IS 7 A1 Obinna Obi-Njoku A1 Chris Bell A1 Prashant Ravindran Menon A1 Iqbal Shergill YR 2019 UL http://casereports.bmj.com/content/12/7/e229290.abstract AB The ureter is an extremely rare site for small cell neuroendocrine carcinoma. We present a case of this disease in a patient who presented without urological symptoms. The multidisciplinary team proposed nephroureterectomy (if fit) or watchful waiting as management. After discussion with the patient a decision in favour of watchful waiting was made. We report her case including a review of the literature, and emphasise that although small cell neuroendocrine carcinomas can be very aggressive, they can remain asymptomatic.
