[Intrapericardial rhabdomyosarcoma in infancy (author's transl)]
Summary
A rare infant intrapericardial tumor, initially myxosarcoma, metastasized intracranially as rhabdomyosarcoma, highlighting childhood cancer pleomorphism. This case underscores the aggressive nature and diagnostic challenges of pediatric malignant intrapericardial tumors.
Area of Science:
- Pediatric Oncology
- Cardiovascular Pathology
- Pediatric Neurosurgery
Background:
- Intrapericardial tumors are rare in infancy.
- Malignant intrapericardial tumors present diagnostic and therapeutic challenges.
- Childhood rhabdomyosarcoma can exhibit significant histologic pleomorphism.
Observation:
- A three-month-old infant presented with cardiac failure and stridor due to an intrathoracic tumor.
- Biopsy confirmed an intrapericardial myxosarcoma.
- Despite treatment, the infant developed multiple intracerebral metastases.
Findings:
- The metastatic lesions showed a histologic transformation to rhabdomyosarcoma.
- This case represents a rare instance of primary malignant intrapericardial tumor in infancy.
- The histologic changes observed are similar to only one previously reported case of pericardial rhabdomyosarcoma.
Implications:
- This case highlights the potential for histologic pleomorphism in childhood rhabdomyosarcoma.
- It emphasizes the need for thorough diagnostic evaluation of pediatric cardiac masses.
- Further research into rare pediatric malignancies and their metastatic potential is warranted.
