A case of testicular tumor of ovarian epithelial type

: Testicular tumors of ovarian epithelial types are rare, and their etiology is unknown. Moreover, a clear treatment policy has not become settled. Under the diagnosis of a testicular tumor, this patient underwent a high orchiectomy, and the pathology revealed testicular tumor of ovarian epithelial type. CA125 was elevated for three years post-operatively and a recurrence was discovered in the left inguinal region by positron emission tomography-computed tomography. Therefore, tumor extirpation was performed. The pathology result confirmed the recurrence of testicular tumor of ovarian epithelial type. After the surgery, the patient was given combined therapy with paclitaxel and carboplatin, which is a regimen of ovarian cancer, on a triweekly basis. After five courses of this therapy, the patient remains in remission.
