Nonseminomatous Germ Cell Tumor of the Testes Metastatic to the Corpus Cavernosum of the Penis

Metastases to the penis are rare, with less than 200 cases reported. Within the genitourinary tract, advanced prostate cancer is the most common culprit. These cases typically represent widely disseminated disease and are associated with a poor prognosis. We present images of a case of a testicular nonseminomatous mixed germ cell tumor, which metastasized to the corpus cavernosum of the penis 8 months after a negative bilateral retroperitoneal lymph node dissection. The patient received chemotherapy and experienced a complete response.
