A 53-year-old male was found to have a hard nodule on digital rectal examination; magnetic resonance imaging revealed a large nodule on the left side of the prostate, indicating prostate cancer. However, pathological diagnosis of the biopsy specimen was benign prostatic hyperplasia. Although a papillary tumor in the prostatic urethra was also seen on urethrocystoscopy, the tumor specimen obtained from transurethral resection was not malignant. The tumor in the prostatic urethra recurred only 3 months after transurethral resection, and pathological findings revealed benign hyperplasia not only in the stromal tissue but also in the epithelium; therefore, the prostate tumor was suspected to be STUMP. It took many prostate pathologists a long time to reach the final diagnosis of STUMP. STUMP is a rare benign tumor, difficult to diagnose, and sometimes transforms into stromal sarcoma. Thus, we should consider radical resection in such cases.<\/jats:p>","DOI":"10.1155\/2015\/879584","type":"journal-article","created":{"date-parts":[[2015,12,29]],"date-time":"2015-12-29T21:04:03Z","timestamp":1451423043000},"page":"1-5","source":"Crossref","is-referenced-by-count":4,"title":["Prostatic Stromal Tumor of Uncertain Malignant Potential Which Was Difficult to Diagnose"],"prefix":"10.1155","volume":"2015","author":[{"given":"Satoko","family":"Matsuyama","sequence":"first","affiliation":[{"name":"Department of Urology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Nohara","sequence":"additional","affiliation":[{"name":"Department of Urology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shohei","family":"Kawaguchi","sequence":"additional","affiliation":[{"name":"Department of Urology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chikashi","family":"Seto","sequence":"additional","affiliation":[{"name":"Department of Urology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Nakanishi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akio","family":"Uchiyama","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin","family":"Ishizawa","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toyama Prefectural Central Hospital, 2-2-78 Nishinagae, Toyama, Toyama 930-8550, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2013-0212-RS"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199802000-00002"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200606000-00004"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.4046\/trd.2010.69.4.284"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.4081\/rt.2010.e57"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1827.2002.01417.x"}],"container-title":["Case Reports in Urology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/criu\/2015\/879584.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criu\/2015\/879584.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criu\/2015\/879584.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T19:09:41Z","timestamp":1469646581000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/criu\/2015\/879584\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":6,"alternative-id":["879584","879584"],"URL":"https:\/\/doi.org\/10.1155\/2015\/879584","relation":{},"ISSN":["2090-696X","2090-6978"],"issn-type":[{"value":"2090-696X","type":"print"},{"value":"2090-6978","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
