A pediatric yolk sac tumor of the testis was diagnosed in a 16-month-old boy. Surgical removal and monitoring of alpha-fetoprotein levels led to a positive outcome one year post-surgery.

Area of Science:

  • Pediatric Oncology
  • Spermatocytic Tumors
  • Tumor Markers

Background:

  • Yolk sac tumors (YSTs) are rare germ cell tumors, predominantly occurring in infants and children.
  • Testicular YSTs in pre-pubertal boys are uncommon and typically present with a good prognosis after treatment.
  • Alpha-fetoprotein (AFP) is a crucial tumor marker for monitoring YSTs.

Observation:

  • A 16-month-old boy presented with an incidentally discovered right testicular mass.
  • The patient underwent a right inguinal orchiectomy for the mass.
  • Histopathological examination confirmed the diagnosis of yolk sac tumor of the testis.

Findings:

  • Preoperative serum AFP levels were markedly elevated at 13568.9 ng/ml.
  • Postoperative serum AFP levels significantly decreased to 118 ng/ml by 12 months.

  • The patient demonstrated a favorable clinical status one year after surgery.

    • Implications:

    • This case highlights the importance of prompt diagnosis and surgical management of pediatric testicular yolk sac tumors.
    • Serial monitoring of serum AFP is essential for assessing treatment response and detecting recurrence.
    • Early detection and treatment of testicular YSTs in children can lead to excellent long-term outcomes.
