A rare case of angioleiomyoma of the larynx is presented.
The patient was a 71-year-old man with a chief complaint of bloody sputum. Laryngoscopy showed a globular tumor-like swelling of the right false cord at the margin of the aryepiglottic fold and arytenoid. The tumor was covered with normal mucosa. After tracheotomy, biopsy was performed under laryngomicroscopy. Histopathologically, the tumor mass composed of proliferating smooth muscle fibers and dilated blood vessels. The tumor was diagnosed as an angioleiomyoma. The tumor was removed completely by an external surgical approach and the bleeding was controlled. It was measuring 1.9×2.0×2.7cm. The patient has shown no evidence of recurrence over a 1 year and eight month period.
Our extensive survey of the literature revealed 18 reports of angioleiomyoma of the larynx. Angioleiomyoma is a benign tumor. However, after the leiomyoma of the hypopharynx was removed, the tumor was recurrent as a leiomyosarcoma. And Two cases were recurrent because of incomplete resection. It suggests that complete resection of these lesions is important and that the patients showed be monitored for recurrence on a regular basis after surgery.
