Summary

Background: The authors present a case of a patient with an extremely rare lung tumor in a child. Case: A 9-year-old girl with a 3-day history of dyspnea and stabbing pain in the xiphoid region, irradiating to the area under the left costal margin, both in rest and in physical activities. She was primarily examined in a regional hospital with bounded homogenous focus of the superior right lung lobe on the X-ray. After initial treatment with antibio­tics and persistent finding on X-ray, a CT scan of the chest was performed. It revealed an irregular oval lesion of a non-homogenous structure with a contrast dye in the S3 region merged to pericardium and parietal pleura, which the presence of several micronodules. Based on the negative tumor markers, positive PET-CT scan and a negative etiology, bio­psy or eventually a lesion exstirpation were indicated. Right-sided thoracotomy, mass enucleation and exstirpation of nodular lesions were performed 2.5 months after the onset of difficulties. Postoperative recovery was uneventful, no sign of recurrence occurred during a follow-up period. The final histological finding was verified as an inflammatory myofibroblastic tumor – an extremely rare pulmonary pathology in the pediatric population. Conclusion: Inflammatory myofibroblastic tumor can be mimicking IgG4 sclerosing disease and inflammatory pseudotumor. It is essential to distinguish between these affections because of different (i.e. surgical vs. conservative) treatment approach.
