Pleomorphic adenomas most commonly arise in the major salivary glands and rarely in the larynx. We report herein on a case of pleomorphic adenoma of the larynx. A 65-year-old female complained of hoarseness for 6 months. Laryngoscopy revealed a tumor located under the mucosa of the left false vocal cord. Tumor resection was performed via an external approach. The tumor was 24×21×13 mm in diameter and consisted of a white solid mass. The histological diagnosis was pleomorphic adenoma. More than 4 years after surgery, the patient has shown no evidence of recurrence and no subjective symptoms. According to the anatomical location, we considered that the tumor had arisen from the laryngeal glands in the laryngeal ventricle. To treat pleomorphic adenomas of the larynx, surgical resection is primarily recommended. An external approach through the thyrohyoid membrane was selected because we thought it was possible to exfoliate the tumor easily from the surrounding tissue and transoral resection was difficult based on the size, location and shape.
