A clinically unsuspected nasopharyngeal sarcoidosis.

Sarcoidosis is a multi-system disease which rarely involves the upper respiratory tract, leading to hoarseness, dysphagia, laryngeal paralysis, and upper airway obstruction. The Waldeyer's ring involvement in sarcoidosis is also very rare. In this article, we report a 32-year-old male case in whom a nasopharyngeal mass was detected based on the Waldeyer's ring involvement due to sarcoidosis.
