[Clinical characteristics, diagnosis and treatment of pulmonary inflammatory myofibroblastic tumor in children].

To explore the clinical characteristics, diagnosis and treatment of pulmonary inflammatory myofibroblastic tumor in children. The clinical data of 13 patients with pulmonary inflammatory myofibroblastic tumor between October 2009 and October 2015 were retrospectively analyzed, including 9 boys and 4 girls aged 1 to 12 years 4 months (mean 4 years 9 months). Seven patients underwent total tumor resection, 4 had lobectomy, 1 had partial tumor resection and 1 had biopsy. The follow-up time ranged from 2 months to 6 years and 2 months. Among the 13 patients, 9 were cured. Two patients lived with tumor. One of them had tumor which shrinked gradually and the other had stable disease. One patient with multiple lesions encountered recurrence after 3 operations and developed suspicious hepatic metastasis. One died during the operation because of airway mismanagement. Pulmonary inflammatory myofibroblastic tumor in children has rather good prognosis while a few cases have the potential of recurrence and canceration. Surgery is the primary therapeutic approach. Close post-operative follow up is necessary.
