A 69-YEAR-OLD white man with a history of chronic obstructive pulmonary disease presented to the emergency department with slowly progressive shortness of breath, cough, and stridor. Mechanical ventilation was necessary because of worsening respiratory acidosis. However, repeated intubation attempts were unsuccessful because the endotracheal tube could not be passed beyond the vocal folds. An emergent tracheostomy was then performed. A computed tomographic scan revealed a subglottic mass (Figure 1), and panendoscopy was subsequently performed. A smooth, firm mass was found filling the subglottic region. The overlying mucosa was smooth and intact (Figure 2). Biopsy of the mass revealed a gelatinous core with tumor in the laryngeal mucosa (Figure 3).
