Giant Epiglottic Inclusion Cyst.

Epiglottic inclusion cysts are extremely rare benign laryngeal lesions. A 41-year-old woman suffered from persistent pharyngeal foreign body sensation for one year. Laryngoscopy detected a giant epiglottic cyst, and contrast-enhanced cervical CT showed the typical pedunculated 'apple sign'. Under fiber optic intubation, complete resection was performed by suspension laryngoscopic coblation. Histopathology verified epiglottic inclusion cyst. Pathognomonic apple sign significantly contributes to precise preoperative diagnosis and individualized surgical planning. Transoral plasma resection provides a safe, effective and low recurrence therapeutic option for this rare laryngeal disease.
