The abdominal computed tomography showed a solid, vegetant lesion in the left renal pelvis, conditioning marked hydronephrosis. The patient underwent radical nephroureterectomy. The histological examination showed a large cell neuroendocrine carcinoma associated with a high-grade urothelial carcinoma, with local invasion (pT3). Large cell renal neuroendocrine carcinomas are rare tumors with an aggressive course and a bad prognosis. At present, only five cases were reported in literature. <\/jats:p>","DOI":"10.5301\/urologia.5000033","type":"journal-article","created":{"date-parts":[[2014,5,14]],"date-time":"2014-05-14T12:28:19Z","timestamp":1400070499000},"page":"57-59","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Primary Large Cell Neuroendocrine Carcinoma of the Renal Pelvis: A Case Report"],"prefix":"10.1177","volume":"81","author":[{"given":"Carlotta","family":"Palumbo","sequence":"first","affiliation":[{"name":"Department of Urology, University of Milan, IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico di Milano, Milan -
