      Summary

      Although inflammatory myofibroblastic tumors (IMTs) are seen in the lower respiratory tract in the pediatric population, few cases occurring in the larynx have been reported in the literature. Treatment of choice is complete surgical excision because of risk of recurrence. We describe a case of pediatric subglottic IMT presenting with progressive hoarseness and symptoms of persistent reactive airway treated with potassium titanyl phosphate laser. We also enumerate the number of pediatric cases of IMT that occur in the larynx and subglottis compared with those which occur in the upper respiratory tract, specifically the trachea and bronchi. To the best of our knowledge, this is the first reported case of respiratory tract IMT excision using a potassium titanyl phosphate laser and the second reported case of a pediatric laryngeal IMT showing anaplastic lymphoma kinase-1 immunoreactivity.
