Inflammatory myofibroblastic tumor is extremely rare in the larynx and can mimic a malignant process. We present the case of a 62-year-old male who required tracheotomy due to rapidly progressive stridor. Laryngoscopy showed an exophytic, occlusive tumor located in the right true vocal cord. CT showed an expansive mass measuring 2×2×1.3 cm 3 and occupying the anterior commissure, with glottic progression to the right true vocal cord. The tumor was completely resected with a CO 2 laser via a transoral approach. Histologic examination demonstrated extensive ulceration with the presence of granulation tissue. The specimen was mainly composed of spindle cells arranged in a fasciculated pattern with a myxoid background and focal hyalinization. Immunohistochemical studies revealed positivity of spindle cells to vimentin, muscle-specific actin and smooth muscle actin. The patient showed no evidence of disease 24 months after surgery.
