A 45-year-old woman was referred to a tertiary care center for hoarseness. She had a left vocal fold polyp that was removed 2 months earlier at an outside institution, with benign pathology reported. Subsequent stroboscopy revealed a hemorrhagic-appearing polyp (2-3 mm). She was sent for preoperative voice therapy, with plans for excision. However, her voice worsened with therapy, and she returned to the otolaryngology clinic after a few weeks. A larger, 6- to 7-mm, irregular, left vocal fold mass was noted. Preoperative imaging was nonspecific, revealing a small soft-tissue density along the true vocal fold. The patient was taken to the operating room for excision (Figure, A). After the final pathology results were obtained, the patient was taken back to the operating room for cordectomy with negative margins.

B. Inflammatory myofibroblastic tumor
Inflammatory myofibroblastic tumors (IMTs) are rare, neoplastic lesions that commonly involve the lungs or abdominopelvic region.1,2 Head and neck involvement is very uncommon, with the larynx most frequently affected.3 Laryngeal IMTs has a predilection for the true vocal cords, subglottis, and aryepiglottic folds.2,3 Although persons of any age may be affected, IMTs tend to occur in the fifth decade of life.2 Symptoms are secondary to mass effect, with 74% of patients presenting with hoarseness or dysphonia, dyspnea, dysphagia, globus sensation, otalgia, cough, and stridor.2,3
Laryngeal IMT accounts for less than 1% of all respiratory tract tumors and remains poorly understood.4 The cause of laryngeal IMT has yet to be completely elucidated; however, predisposing factors may include smoking, trauma, infection (Epstein-Barr virus and human herpesvirus-8), and immunologic factors.1- 3 Up to 70% of IMT cases have overexpression of the ALK protein, secondary to genetic abnormalities involving chromosome 2p23, a finding that supports its neoplastic nature.1,4,5 Aberrations in the ALK protein have been demonstrated in several other tumors, including rhabdomyosarcoma, renal cell carcinoma, non–small cell lung cancer, glioblastoma, and its namesake, anaplastic large-cell lymphoma.5
