A Case of Acute Airway Obstruction due to Intracystic Hemorrhage of Thyroid Papillary Cancer / 대한이비인후과학회지

ABSTRACT

Thyroid papillary cancer is the most common type of thyroid cancer and the incidence rate is 70-80% of entire thyroid cancer. 10-year survival rate is more than 90%. It is mostly irregular marginated- hard mass but, may have cystic property. The most common clinical symptom is silent neck mass, but rapid growth or local invasion may develope the symptoms such as pain, hoarseness, dysphagia, hemoptysis and dyspena. With the 10% of invasion rate, it spreads to adjacent muscle, recurrent laryngeal nerve, pharynx, larynx, trachea, esophagus and spinal cord. We report a case of acute airway obstruction due to intracystic hemorrhage of thyroid papillary cancer which invades the retropharynx.
