Leiomyosarcoma of the larynx : Review of the literature and report of two cases

Leiomyosarcoma of the larynx is an extremely rare malignancy. Until now, only 35 cases have been reported, and only 19 were reported in English. We present 2 new cases observed in the last 3 years at our department. Correct histologic diagnosis can only be made on immunohistochemical and electron microscopic grounds. A 65-year-old man previously treated for a premalignant vocal cord lesion and a 31-year-old woman who previously underwent operation on a benign vocal cord lesion are presented. Only surgical treatment (total laryngectomy and endolaryngeal laser resection) was performed. Thirty-six and 22 months after the initial surgical intervention, both patients are alive and well, with no evidence of local recurrence or distant metastasis.
