Fibrous neoplasms of the adult larynx

Fibrous neoplasms of the adult larynx are uncommon and can be benign, locally aggressive, or malignant. From January 1, 1987 to December 31, 1991, 189 adult patients underwent partial or total laryngectomy for laryngeal neoplasms at the University of Texas Southwestern Medical Center-affiliated hospitals. During this period, three (1.6%) patients were treated for fibrous neoplasms of the larynx. All three lesions arose in the true vocal fold. In one patient, a local recurrence within 6 months following partial laryngeal resection necessitated total laryngectomy. All three patients are alive and disease-free 1 to 4 years following definitive surgery. We present these cases and discuss computed tomographic (CT), histopathologic, and electron microscopic (EM) findings. Based on this experience, surgical treatment of these lesions is recommended, the extent of which is guided by clinical, radiologic, and pathologic evaluation.
