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.

Pleomorphic adenoma is most frequently seen in the major salivary glands. Pleomorphic adenoma in minor salivary gland is relatively rare and can be found in palate, lip, buccal mucosa, tongue, oropharynx, nasal cavity, paranasal sinus, parapharynx as well as in the nasopharynx. Pleomorphic adenoma of nasopharynx is very rare, and only a few cases were reported both in neonates (congenital type) and adults (acquired type). We report the adult case of nasopharyngeal pleomorphic adenoma (Eustachian tube origin) with a review of literature.
