A 14-year-old, otherwise healthy adolescent male originally presented to his primary care physician with abdominal pain and distention. Ultrasound revealed a complex mass with cystic components along the superior pole of the bladder and bilateral hydroureteronephrosis down to the level of the bladder.

A 70-year-old, otherwise healthy man presented to his primary care provider for an annual checkup, at which time a nontender right testicular mass was noted. He denied any symptoms, and his serum alpha-fetoprotein and beta-human chorionic gonadotropin levels were normal.
