Background: Although testicular cancer and Hodgkin disease are the neoplasms with the highest incidence in young men, only 13 cases of metachronous and 2 cases of synchronous occurrence in the same person were reported before 1991.
Methods: A 30-year-old man is described, in whom, 2 years after radiation therapy for Stage IIIA Hodgkin disease, a testicular nonseminomatous germ cell tumor developed with metastatic spread to the retroperitoneal lymph nodes, lung, and left supraclavicular fossa. The second case report describes a 31-year-old man in whom a metastasizing nonseminomatous testicular cancer, with elevation of levels of the serum tumor markers alpha-fetoprotein and human chorionic gonadotropin, developed simultaneously with axillary lymphadenopathy that was histologically confirmed Hodgkin disease.
Results: After five cycles of cisplatin-based chemotherapy and secondary retroperitoneal lymphadenectomy, the patient with metachronous disease has remained in complete remission for 8 years. The patient with synchronous occurrence has been disease-free for 14 months after five cycles of chemotherapy consisting of cisplatin, etoposide, and doxorubicin (Adriamycin, Adria Laboratories, Columbus, OH).
Conclusions: The metachronous and synchronous occurrence of testicular cancer and Hodgkin disease is a rare association of two curable neoplasms. The presence of both malignant neoplasms should be taken into consideration in young male patients, especially if disease distribution diverges from a regular pattern.
