We report a rare case of simultaneous bilateral testicular germ cell tumors arising from uncorrected cryptorchid testes. Each side had a different histological type, which consisted of pure high grade seminoma on the left side, and teratocarcinoma with choriocarcinoma and yolk sac tumor elements in addition to seminoma on the right side. Patients with cryptorchidism are known to have a higher risk of germ cell tumors. Genetic factors also may have a role in the oncogenesis in our patient, since… CONTINUE READING
