  • Pediatric testicular tumors are rare in the prepubescent male (Figure 54.1).

  • Germ cell tumors (GCTs) comprise the majority of testicular tumors in the pediatric population.


  • The most common type of GCT in the pediatric population is yolk sac tumors, followed by teratomas.1

    • Yolk sac tumors are malignant and express alpha fetoprotein (AFP).

    • In contrast to adults, teratomas in children are often benign and lack immature components.2,3

  • Epidermoid cysts are another common benign testicular tumor in children.

  • The next most common category is gonadal stromal tumors, including sertoli cell tumors, leydig cell tumors, and juvenile granulosa cell tumors, in respective order of approximate incidence.

  • Seminomatous GCTs are rare in children.

  • Paratesticular rhabdomyosarcomas are the most common malignant tumor of the paratesticular structures.

    • Often arise from the spermatic cord, tunicae, or epididymis.

    • Highly aggressive and warrant retroperitoneal lymph node dissection (RPLND) and metastatic workup.4

  • Secondary tumors are most commonly leukemia or lymphoma.

  • Cryptorchidism is classically associated with an increased relative risk of GCT (RR˜3-8) in the undescended testicle, which is only reduced but not eliminated (RR˜2-3) after prepubertal orchiopexy.5

  • Testicular tumors typically present as a painless testicular mass incidentally found by the patient or parent or on clinical examination.

  • There is often an associated hydrocele occurring in ˜1 in 5 patients.6
