A false cord mass is very rare, and the condition is associated with airway morbidity if it is not recognized and addressed at an early stage. The mass could be an extension from a glottic and subglottic area, and the tissue diagnosis is mandatory to rule out carcinoma. We are presenting an elderly woman who came to us due to worsening hoarseness with an endoscopic finding of false cord mass that turned out to be schwannoma as a histological diagnosis.
