- 2 incidence peaks at 2–6 yr and 15–19 yr
- 0.5–0.7 cases per million children <15 yr (1)

- Most common tumor of paratesticular tissues, accounting for 30%
- Occurs predominantly during the 3rd and 4th decade of life
- Rhabdomyosarcoma:

- In children and adolescents, paratesticular tumors account for 6% of all rhabdomyosarcoma.
