Isolated corpora cavernosa germ cell tumor metastasis requiring complex excision and reconstruction

Germ cell tumors (GCT) are rare, frequently diagnosed in men aged 20-34 years old, and have a 95% 5-year relative survival rate. Metastasis from GCT has predictable spread to retroperitoneal lymph nodes. However, in cases of scrotal violation or tumor spillage, lymphatic drainage can be altered. Beyond the retroperitoneum, the most reported extra-nodal sites of metastases include the liver, lung, brain, and bone. Here we report a case of an unusual site of metastasis to the corpora cavernosa, as well as the complex reconstruction required to preserve sexual function.
