A 41 years female patient was hospitalized with hoarseness for three months, without cough, expectoration and dyspnea. The symptom had no relief by application of antibiotics. Electronic laryngoscope showed that there were the grey neoplasms under subglottic anteriou commissure with broad base and slightly rough surface, and bilateral vocal cords were normal; throat CT showed subglottic irregular high density and calcification.
