Insights
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.
Abstract:
A 16-months old normal boy, a right testicular mass was discovered incidentally by his grandmother. Right inguinal orchiectomy was performed. Histological examination showed yolk sac tumor of testis. A preoperative alpha-fetoprotein level was markedly elevated at 13568.9 ng/ml, by the end of the twelve postoperative months, the serum alpha-fetoprotein levels was 118 ng/ml. The patient is doing well one-year postoperatively.
