Endobronchial inflammatory myofibroblastic tumors (IMTs) rarely occur in children younger than 10 years of age and have intermediate malignant potential. A 7‐year‐old girl initially presented with pneumonia. After failing outpatient treatment, she re‐presented in status asthmaticus. Computed tomography showed a left mainstem endobronchial mass which was resected bronchoscopically. Pathology was consistent with IMT. Surveillance bronchoscopy identified a recurrence. Despite a left upper lobectomy, recurrence led to further treatment with celecoxib and argon plasma coagulation. Follow‐up bronchoscopy revealed complete resolution. She remains disease and symptom‐free at her six‐year follow‐up.
