Insights
This report details a rare case of multifocal mesenchymal hamartoma in an infant's chest wall. Surgical removal was successful, highlighting a unique presentation of this uncommon pediatric tumor.
Area of Science:
- Pediatric Surgery
- Thoracic Oncology
- Developmental Biology
Background:
- Mesenchymal hamartoma is a rare congenital tumor typically affecting the liver.
- Chest wall mesenchymal hamartomas are exceptionally uncommon, with multifocal presentations being exceedingly rare.
Observation:
- An infant presented with incidentally discovered, multifocal mesenchymal hamartomas of the right posterior chest wall on a routine chest radiograph.
- The tumors were identified during evaluation for an unrelated upper respiratory tract infection.
Findings:
- Surgical resection of both multifocal lesions was performed.
- Successful chest wall reconstruction was achieved, resulting in a good clinical outcome.
Implications:
- This case expands the known clinical spectrum of mesenchymal hamartoma, particularly its occurrence in the chest wall.
- Highlights the importance of vigilant radiological assessment for rare pediatric chest wall tumors.
- Contributes to the limited literature on multifocal mesenchymal hamartomas, with only two prior reported cases.
Abstract:
The authors report on an infant who had multifocal mesenchymal hamartoma of the right posterior chest wall. The tumors were found incidentally, on a chest radiograph, during routine evaluation for upper respiratory tract infection. Resection of both lesions with chest wall reconstruction was performed, with a good result. Only 46 cases of this unusual tumor have been reported previously, and only two of them were multifocal.
