Abstract

<p>Laryngeal leiomyosarcoma is a rare malignant tumor of the larynx. Its symptoms are nonspecific and difficult to diagnose, and no treatment has been established. We report a case of laryngeal leiomyosarcoma. The patient, a 57-year-old man, presented to our hospital with a polyp on the left vocal fold that was unresponsive to conservative treatment. Flexible fiberscopy showed a submucosal tumor in the anterior third of the left vocal fold, which was suspected to be a left vocal fold cyst, and direct laryngoscopy was performed. One month after surgery, the tumor recurred, and laryngeal stroboscope showed loss of mucocutaneous wave motion over the entire left vocal fold, leading us to suspect a submucosal malignant tumor. Based on a second examination by direct laryngoscopy, the case was diagnosed as laryngeal leiomyosarcoma. Vertical partial laryngectomy was selected for curative resection. Six months have passed since the surgery, and the patient has progressed without local recurrence. Although total laryngectomy was often selected in the relevant literature, vertical partial laryngectomy should be considered as a treatment option from the viewpoint of the extent of the tumor and the preservation of postoperative phonation.</p>
