We present a 10-year-old male, with right gynecomastia and ipsilateral hydrocele, showing an enlarged right testicle with a volume of 12\u2009ml and a left testicle with a volume of 10\u2009ml. A right orchiectomy was performed, which presented a poorly defined tan tumor of 1.8\u2009cm that occupied the vaginal and epididymal tunica, and infiltrates the testicular parenchyma. Histological sections revealed a cystic neoplasm, with hierarchical papillary projections, covered by one or several epithelial columnar and hobnail cells with moderate atypia and scant mitosis. Immunohistochemical reactions were performed, resulting positive for PAX-8, epithelial membrane antigen, and CK7, confirming the diagnosis of borderline serous tumor. Since the first reported case in 1986, few have been reported, the majority of these in adults with only three cases in children. In the few cases reported, the prognosis is usually favorable after surgical resection, with disease-free follow-up for up to 18 years.<\/jats:p>","DOI":"10.1155\/2020\/8789143","type":"journal-article","created":{"date-parts":[[2020,10,20]],"date-time":"2020-10-20T01:20:09Z","timestamp":1603156809000},"page":"1-5","source":"Crossref","is-referenced-by-count":1,"title":["Paratesticular Serous Borderline Tumor in a Pediatric Patient"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0862-2114","authenticated-orcid":true,"given":"Itzel Araceli Ortiz","family":"Meza","sequence":"first","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco Antonio Ponce","family":"Camacho","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodolfo Franco","family":"M\u00e1rquez","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauricio Delgado","family":"Morquecho","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raquel Garza","family":"Guajardo","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oralia Barboza","family":"Quintana","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy and Cytopathology, Universidad Autonoma de Nuevo Leon, Hospital Universitario \u2018Dr Jos\u00e9 Eleuterio Gonz\u00e1lez, Monterrey, Nuevo Le\u00f3n 64460, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/86.2.146"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200103000-00012"},{"key":"3","first-page":"431","article-title":"Borderline serous cystadenoma of the tunica vaginalis testis","volume":"1","author":"A.
