Source abstract
This report highlights the importance of differential diagnosis of laryngeal obstructive airway pathologies, as well as the growing value of endoscopic techniques, such as cryobiopsy, in achieving a definitive, accurate diagnosis. This is an 8-month-old infant who presented with signs of airway obstruction and a history consistent with foreign body aspiration. During endoscopy under general anesthesia, a supraglottic tumor was observed, which was resected using a cryobiopsy probe, a method that is not widely used in pediatrics and in our setting. Postoperative pathological anatomy confirmed the diagnosis of juvenile xanthogranuloma, a form of non-Langerhans cell histiocytosis with an uncommon location in the larynx.
