title: Mixed germ cell-sex cord stroma tumor of the testis. A report with ultrastructural findings.
abstract: The case of a 41-year-old man with testicular mixed germ cell-sex cord stroma tumor is reported. The patient noticed a gradual, painless, right-sided testicular enlargement 4 years before being treated by radical orchiectomy. The testis contained a centrally located tumor. There was no evidence of metastases. An histologic examination and an ultrastructural study showed that the tumor was composed of germ cells and sex cord derivatives; the typical features of mixed germ cell-sex cord stroma tumor were present. The patient is well and disease-free 2 years after the operation. Currently, none of the testicular tumors of this type has been associated with metastases or was overgrown by malignant germ cell tumors, and radical orchiectomy resulted in complete cure. The literature regarding this entity is reviewed, the differential diagnosis is discussed, and the importance of making the correct diagnosis is emphasized.
