title: [Diagnosis and treatment of inflammatory myofibroblastic tumor of the chest].
abstract: OBJECTIVE
  To explore the causes, clinic diagnosis, treatment and prognosis of inflammatory myofibroblastic tumor (IMT) of the chest.
  
  
  METHODS
  The clinical data of 12 patients with IMT were retrospectively analyzed including 9 male and 3 female patients aged 36 to 81 years (mean 60.08 years). Five patients underwent pulmonary lobectomy and mediastinal lymph node dissection, 1 had partial lobectomy, 1 had mediastinal tumor resection and costectomy, and 2 received conservative treatment.
  
  
  RESULTS
  All the surgical patients recovered after surgery without lymph node metastasis detected by pathological examinations. In the follow-up lasting for 2 months to 5 years, no recurrence or metastasis occurred in these cases. In the 2 cases having conservative treatment, the tumor remained unchanged in one case at 3 month of follow-up and disappeared in the other case.
  
  
  CONCLUSIONS
  IMT in the chest is a rare benign tumor with a low incidence rate and malignancy. Pathological examination is reliable for definite diagnosis. Surgical operation is the primary therapeutic approach. All IMT patients should be closely followed up after the treatment.
