laryngeal lipoma; report of two cases

Laryngeal lipoma which is unusual, was diagnosed in two patients : a 71-year-old female who had been suffering from progressive feelings of constriction in the hypopharynx and a 60-year-old female with a foreign body sensation in the hypopharynx. In both a large, bullky mass with intact mucosa was seen in the Vallecula extending from the epiglottis. The mass was surgically removed by means of a laryngomicro technique through the mouth under modified NLA. Light microscopic examination of both surgical specimens revealed mature lipocytes ; the diagnosis was simple lipoma. There has been no recurrence during the 2 years since surgery. We found only 14 cases of laryngeal lipoma reported in the Japanese literatures.
