Left hemiscrotectomy was performed, and pathological examination revealed an epithelioid\u2010type MTVT with invasion into the testis and spermatic cord. Immunohistochemistry was positive for D2\u201040 and calretinin, and negative for cytokeratin 5\/6 and carcinoembryonic antigen. The patient remained disease\u2010free for 12\u2009months postoperatively without adjuvant treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>MTVT should be considered in patients with long\u2010standing or recurrent hydrocele.
