This 21-year-old male was aware of this 10-cm testicular mass for several months before he sought attention. His serum beta-HCG and alpha-fetoprotein were elevated. CT scan showed enlarged retroperitoneal and mesenteric lymph nodes, suspicious for malignancy. The urologist performed an orchiectomy.

The cut surface of the tumor was soft and hemorrhagic. I intially put in 20 sections, but the tumor was almost entirely necrotic. There were a few microscopic foci of what appeared to be syncytiotrophoblast. I put in 30 more sections and am awaitng those slides.
