Inflammatory myofibroblastic tumor of the trachea; report of a case

A 45-year-old female with a complaint of dyspnea was admitted to our hospital. Computed tomography (CT) and bronchoscopy revealed a 10 mm intraluminal polypoid tumor with a smooth surface and hemorrhagic tendency located in the tracheal wall 2.0 cm distal from the vocal cords. For pathological diagnosis, airway management and hemorrhage control, tumor resection was performed using a rigid bronchoscope and neodymium yttrium aluminum garnet (Nd-YAG) laser under general anesthesia. Histologically, the tumor was diagnosed as an inflammatory myofibroblastic tumor of the trachea. Inflammatory myofibroblastic tumor is typically a benign tumor that develops in such sites as the lung, stomach, and mesentery. To the best of our knowledge, this is the first reported case of an inflammatory myofibroblastic tumor arising in the trachea.
