Here, we present a second cystadenofibroma originating from the epididymis of a 54-year-old man who presented with painful swelling in the scrotum. The scrotal mass measured 6.3\u2005cm and contained a clear yellow, serous to gelatinous fluid-filled cyst with internal papillae. Microscopically, the mass contained both stromal and epithelial components. The stromal component consisted of spindle cells arranged in small intervening fascicles, forming simple cyst and papillae. The cyst and papillae were lined by cuboidal to columnar and ciliated epithelium. Immunohistochemistry staining showed that the stromal component was positive for estrogen receptor, progesterone receptor, and CD10, which are characteristic of ovarian-type stroma. However, the epithelium lining was positive for keratin cocktail AE1\/3&amp;CAM5.2, CD10, PAX8, androgen receptor, and alpha-1 antitrypsin, suggesting a possible Wolffian duct origin.<\/jats:p>","DOI":"10.1177\/10668969231201412","type":"journal-article","created":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T05:58:50Z","timestamp":1694843930000},"page":"948-951","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Papillary Cystadenofibroma of the Epididymis: A Case Report"],"prefix":"10.1177","volume":"32","author":[{"given":"Xenia","family":"Parisi","sequence":"first","affiliation":[{"name":"Beth Israel Deaconess Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Feinstein","sequence":"additional","affiliation":[{"name":"Department of Radiology, Beth Israel Deaconess Milton, Milton, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yekaterina","family":"Merkulova","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4499-5221","authenticated-orcid":false,"given":"Yue","family":"Sun","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,9,16]]},"reference":[{"issue":"6","key":"e_1_3_2_2_2","first-page":"629","article-title":"Papillary cystadenofibroma of epididymis: a case report","volume":"4","author":"Iczkowski KA","year":"2011","unstructured":"Iczkowski KA, Pantazis CG.
