Abstract:
An inflammatory myofibroblastic tumor as a distinct clinicopathologic entity in the lung has gained wide acceptance. The majority of these tumors are either contained within a single segment or pulmonary lobe and may cross the interlobar fissure and/or extend into the mediastinum, especially if arising in a perihilar location. We describe the case of a 13-year-old male with a 4-year history of an unresponsive lung mass in the left hemithorax. The resected tumor showed the typical morphology of a fasciculated fibroblastic/myofibroblastic lesion.
