Gradual increase in the size of this lesion over the year prior to his presentation to our clinic prompted scrotal ultrasound that demonstrated a 1.1\u2009cm solid lesion, which appeared to arise from the right epididymal tail. Subsequent positron emission tomography (PET) scan showed intense focal uptake at the base of the right testicle, suspicious for epididymitis versus underlying neoplasm. Scrotal exploration through an inguinal approach revealed a paratesticular mass. Frozen section from an excisional biopsy was positive for adenocarcinoma. Radical orchiectomy was completed. Final pathology returned as metastatic adenocarcinoma involving soft tissue; testis and spermatic cord were without diagnostic abnormalities and surgical margins were not involved. Subsequent analysis was consistent with colorectal origin. The patient recovered well from surgery and is continuing treatment of metastatic colon cancer per the medical oncology team.<\/jats:p>","DOI":"10.1136\/bcr-2019-233106","type":"journal-article","created":{"date-parts":[[2020,2,6]],"date-time":"2020-02-06T04:34:21Z","timestamp":1580963661000},"page":"e233106","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Paratesticular colon cancer metastasis in an area of remote trauma"],"prefix":"10.1136","volume":"13","author":[{"given":"Moshe","family":"Wald","sequence":"first","affiliation":[{"name":"Urology, University of Iowa Roy J and Lucille A Carver College of Medicine, Iowa City, Iowa, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,2,5]]},"reference":[{"key":"2025082711021826000_13.2.e233106.1","first-page":"340","article-title":"Epididymis metastasis from colon carcinoma: a case report and a review of the Japanese literature","volume":"24","author":"Kanno","year":"1994","journal-title":"Jpn J Clin Oncol"},{"key":"2025082711021826000_13.2.e233106.2","doi-asserted-by":"crossref","first-page":"321","DOI":"10.1007\/BF02710272","article-title":"Epididymal metastases as the first sign of a colon cancer recurrence","volume":"7","author":"Moreno Ant\u00f3n","year":"2005","journal-title":"Clin Transl Oncol"},{"key":"2025082711021826000_13.2.e233106.3","doi-asserted-by":"crossref","first-page":"621","DOI":"10.1016\/S0022-5347(17)41740-X","article-title":"Testicular metastasis as the first manifestation of colon carcinoma","volume":"140","author":"Meacham","year":"1988","journal-title":"J Urol"},{"key":"2025082711021826000_13.2.e233106.4","doi-asserted-by":"crossref","first-page":"746","DOI":"10.4321\/S0004-06142006000700014","article-title":"[Metastasis of colon adenocarcinoma to the epididymis and spermatic cord]","volume":"59","author":"Janeiro Pais","year":"2006","journal-title":"Arch Esp Urol"},{"key":"2025082711021826000_13.2.e233106.5","doi-asserted-by":"crossref","DOI":"10.1186\/1477-7819-12-128","article-title":"Late-onset metastatic adenocarcinoma of the spermatic cord from primary gastric cancer","volume":"12","author":"Kim","year":"2014","journal-title":"World J Surg Oncol"},{"key":"2025082711021826000_13.2.e233106.6","first-page":"266","article-title":"Metastatic ampullary adenocarcinoma presenting as a hydrocele: a case report","volume":"15","author":"Lane","year":"2014","journal-title":"JOP"},{"key":"2025082711021826000_13.2.e233106.7","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2015-210046","article-title":"Primary colonic adenocarcinoma diagnosed with cutaneous shave biopsy","volume":"2015","author":"Abt","year":"2015","journal-title":"BMJ Case Rep"},{"key":"2025082711021826000_13.2.e233106.8","doi-asserted-by":"crossref","first-page":"94","DOI":"10.5173\/ceju.2012.02.art10","article-title":"A case of descending colon carcinoma metastasized to left spermatic cord, testis, and epididymis","volume":"65","author":"Al-Ali","year":"2012","journal-title":"Cent European J Urol"},{"key":"2025082711021826000_13.2.e233106.9","doi-asserted-by":"crossref","first-page":"591","DOI":"10.1016\/j.radcr.2019.02.019","article-title":"MR imaging of paratesticular bilateral leiomyoma: a case report","volume":"14","author":"Dell'Aversana","year":"2019","journal-title":"Radiol Case Rep"},{"key":"2025082711021826000_13.2.e233106.10","doi-asserted-by":"crossref","first-page":"84","DOI":"10.1016\/j.urology.2019.03.007","article-title":"Free-Floating paratesticular calcifying fibrous pseudotumors in a pediatric patient","volume":"128","author":"Payne","year":"2019","journal-title":"Urology"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-233106","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T18:02:23Z","timestamp":1756317743000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-233106"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2]]},"references-count":10,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2020,2,5]]},"published-print":{"date-parts":[[2020,2]]}},"alternative-id":["10.1136\/bcr-2019-233106"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-233106","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2020,2]]}}}
