Abstract
Testicular choriocarcinoma is a non-seminomatous germ cell tumor (NSGCT) and is the rarest of all testicular cancers. Nearly all choriocarcinomas can be classified as either pure choriocarcinoma or as a component of a mixed germ cell tumor. Pure testicular choriocarcinoma is extremely aggressive and metastasizes early and extensively. We present a case of testicular cancer that metastasized to the skin, gastrointestinal tract, and brain, and discuss the case in light of the available literature.
