Introduction: To report a rare case of laryngeal leiomioma. Tumors of smooth muscle origin are rare in the upper aerodigestive tract, due to the paucity of smooth muscle in the area. A review of the literature confirm that this kind of neoplasm is extremely rare in the larynx and not so many cases were described in the literature so far. We described classification, treatment and clinical course of laryngeal leiomioma.
Material and methods: We encountered such a tumor in a 68-year-old men who was admitted to our Hospital. Hoarseness since 2 years was a main symptom.
Results: The tumor was removed endoscopically and was located under left vocal cord. The patient recovered well but after 6 months was admitted again to our Hospital due to recurrence of ailments. Tracheotomy and enlarged chordectomy on the left side of larynx was performed under general anesthesia. The tumor was encapsulated and could be completely resected. No complications were observed in the postoperative course and patient was discharged from the hospital in 5th day after operation. There was no evidence of loco regional recurrence 4 years post surgery and laryngeal function was preserved. All histological pictures of the specimens from the first and second operation indicated tumor as a laryngeal leiomioma.
Conclusion: Laryngeal leiomioma is a very infrequent neoplasm and to our knowledge, this is the 38th case of laryngeal smooth muscle tumor to be reported in the world literature.
