A 44‐year‐old man collapsed after complaining of difficulty breathing. Layer dissection of the neck at autopsy revealed a large mixed internal and external laryngopyocele occluding the upper airway. It contained 30 mls of yellow‐gray pus. Mechanisms of death in laryngoceles involve obstruction of the opening into the larynx resulting in accumulation of mucus or air within the sac causing airway occlusion. Once infection supervenes, deaths in laryngopyocoeles result either from accumulated pus causing airway occlusion from a mass effect (as in the current case) or the discharge of pus into the airway causing death from aspiration. Sudden death in laryngopyoceles is a very rare event that requires careful dissection at autopsy to demonstrate the characteristics of the underlying lesion and the possible mechanism of death. Laryngopyocele should be considered in the differential diagnosis of natural conditions causing acute, potentially lethal, upper airway obstruction.
