Adenoid cystic carcinoma of paranasal sinus - about 2 cases

ABSTRACT

Adenoid cystic carcinoma [ACC] is a fairly uncommon malignant disease that accounts for about 1.3% of all paranasal sinus cancers, and occurs most commonly in the minor salivary gl and s of the head and neck. ACC grows slowly. However, it frequently recurs and metastasizes to distant organs such as lung or bone after treatment, and the prognosis is poor. Locally advanced lesions are usually managed best by resection and postoperative radiotherapy
