Summary
A sacrococcygeal teratoma recurred as an endodermal sinus tumor in an infant. Chemotherapy (bleomycin, etoposide, cisplatin) achieved remission, highlighting the need for vigilant monitoring after teratoma resection.
Area of Science:
- Pediatric Oncology
- Surgical Pathology
- Medical Imaging
Background:
- Sacrococcygeal teratomas are congenital tumors that can rarely undergo malignant transformation.
- Early detection and complete resection are crucial for favorable outcomes in pediatric oncology.
Observation:
- A one-week-old infant with a sacrococcygeal teratoma developed a recurrent pelvic mass at 12 months, confirmed as endodermal sinus tumor.
- Imaging revealed metastatic disease including enlarged inguinal lymph nodes and liver lesions.
Findings:
- The patient achieved complete remission following a BEP (bleomycin, etoposide, cisplatin) chemotherapy regimen.
- Serum alpha-fetoprotein levels normalized post-treatment, indicating successful tumor response.
Implications:
- This case underscores the importance of long-term surveillance, including serial alpha-fetoprotein monitoring, after sacrococcygeal teratoma resection.
- Prompt diagnosis and multimodal treatment are essential for managing malignant transformation of pediatric germ cell tumors.
