A Rare Inflammatory Myofibroblastic Tumor of the Lung : Two Cases Reports

Abstract

We describe two cases with a primary lung tumor in which preoperative diagnosis was difficult. An 8year-old boy presented with hemoptysis. He underwent a resection of the left lower lobe with a preoperative diagnosis of congenital cystic adenomatoid malformation. The pathology was inflammatory myofibroblastic tumor (IMT). In the other case, a 15-yearold girl presented with an asthma attack and hemoptysis. The chest X-ray showed an abnormal shadow, suggesting hamartoma or lymphoma. Resection of the right upper lobe was performed, and the pathological diagnosis was IMT. Although IMT is rear, one should consider IMT as a differential diagnosis of primary lung tumors.
