Summary
This study presents a rare case of a pediatric head and neck endodermal sinus tumor (yolk sac tumor). The patient achieved complete remission with chemotherapy, highlighting effective treatment for this rare childhood cancer.
Area of Science:
- Pediatric Oncology
- Head and Neck Surgery
- Tumor Biology
Background:
- Germ cell tumors, especially teratomas, are common in children.
- Head and neck germ cell tumors constitute 6% of cases.
- Endodermal sinus tumors (yolk sac tumors) in the head and neck are exceptionally rare.
Observation:
- A 20-month-old girl presented with a 5 cm left temporal mass and bone destruction.
- Histopathology confirmed an endodermal sinus tumor.
- Elevated serum alpha-fetoprotein (AFP) and lactate dehydrogenase (LDH) levels were noted.
Findings:
- The patient received six cycles of BEP chemotherapy (bleomycin, etoposide, cisplatin).
- A partial response was observed after the first cycle, with complete response after the fourth.
- The patient has remained in remission for five months post-treatment.
Implications:
- This case demonstrates the successful application of BEP chemotherapy for pediatric head and neck endodermal sinus tumors.
- Early diagnosis and prompt treatment are crucial for favorable outcomes in rare pediatric malignancies.
- Further research into the management of head and neck yolk sac tumors is warranted.
