The case is reported of a 64-year-old man in whom a pedunculated tumor of the Vallecula epiglottica occurred and was excised. Histologically it proved to be a dedifferentiated liposarcoma. The patient is well and free of disease 18 months later. The literature is reviewed and 20 other cases of liposarcoma in the laryngeal region are discussed.
Congenital central alveolar hypoventilation (Ondine's curse) is a rare disorder with absence of automatic control of ventilation but preservation of voluntary breathing. Phrenic pacing, used to treat this condition, is usually not successful without a tracheotomy. We performed fiberoptic videoendoscopy on an affected infant airway. During wakefulness and ventilation by a negative pressure ventilator, the airway was normal, but with sleep onset, passive inspiration produced phasic epiglottic collapse. This case demonstrates the importance of central control in maintaining upper airway patency.
