Intrapericardial Immature Teratoma with Successful Treatment in a Neonate

Intra-pericardial teratoma, most often a benign tumor, is an extremely rare condition in a newborn. It can be a diagnostic and therapeutic challenge if it presents with massive pericardial effusion. Complete surgical excision of the tumor is necessary because of its association with tissues of malignant potential. A 16-d-old newborn was diagnosed with intra pericardial immature teratoma (IT) and managed successfully with multidisciplinary team approach by prompt referral for complete surgical resection followed by adjuvant chemotherapy with carboplatin, etoposide and bleomycin (JEB) to prevent recurrence. The infant is now on close follow up with monitoring of serum alpha fetoprotein (AFP) levels and imaging studies for early diagnosis of recurrence of tumor and chemotherapy related complications.
