Inflammatory myofibroblastic tumor of the subglottis in children—Report of a single case with positive anaplastic lymphoma kinase

Background: Dysphonia is a common clinical symptom in children. Methods and results: A seven-year-old boy presented with a chronic dysphonia that was secondary to a subglottal inflammatory pseudotumor. The patient was treated by means of endoscopic microsurgery and is currently asymptomatic and without signs of recidivism. Conclusions: Inflammatory pseudotumor of the larynx is seldom encountered in the pediatric age range, and it is diagnosed by means of specific immunohistochemical techniques. The treatment of choice is endoscopic resection by CO 2 laser. Due to its capacity for recidivism and metastasis, the syndrome requires stringent follow-up.
