Ultrasonography revealed a heterogeneous intratesticular mass with cystic components. Testicular tumor markers were within normal ranges. The patient underwent a left orchiectomy. Pathologically, the tumor was characterized by the presence of medium to large neoplastic cells and small neoplastic cells without sarcomatoid or anaplastic features. Immunohistochemically, the tumor was positive for SALL4 and negative for CD30, AFP, OCT3\/4, PLAP, D2\u201040, and hCG. Based on these findings, we diagnosed spermatocytic tumor of testis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We present a case of spermatocytic tumor, which is a distinct entity among testicular germ cell tumors, with a generally favorable prognosis following orchiectomy. However, long\u2010term follow\u2010up is recommended due to the potential for late metastasis.<\/jats:p>\n
