Summary
A congenital myofibromatosis caused tracheal stenosis in an infant. An expandable metal stent provided immediate relief and long-term success, demonstrating a safe and effective treatment for this rare condition.
Area of Science:
- Pediatric Surgery
- Respiratory Medicine
- Oncology
Background:
- Congenital tracheal stenosis presents a significant challenge in pediatric care.
- Myofibromatosis is a rare benign tumor that can affect various organs, including the trachea.
- Persistent stridor from birth indicated a severe airway obstruction in the infant.
Observation:
- A 10-month-old boy exhibited persistent stridor since birth.
- Imaging and bronchoscopy revealed tracheal narrowing due to myofibromatosis.
- An expandable metal stent was surgically inserted to address the stenosis.
Findings:
- The stent placement resulted in immediate clinical improvement of the stridor.
- No complications were observed during or after the stent insertion procedure.
- Nine-month follow-up bronchoscopy confirmed complete endothelialization of the stent with no granuloma formation.
Implications:
- Expandable metal stents are a viable and safe therapeutic option for congenital tracheal stenosis caused by myofibromatosis.
- This case highlights the potential for successful long-term management of rare pediatric airway tumors.
- Endothelialization of the stent suggests good tissue integration and minimal adverse reactions.
