Testicular germ cell tumors in monozygotic twins: case report and review of the literature

We report the eleventh instance of testicular germ cell tumors in monozygotic twins. The tumors were concomitant but of different histology. The comparable lymphography and computerized tomography scan findings, tumor response to chemotherapy and side effects are discussed. We conclude that there is no definite evidence for an increased risk in relatives of patients with this disease.
