Endoscopic therapy combined with photodynamic therapy for intratracheal inflammatory myofibroblastic tumor

Inflammatory myofibroblastic tumor (IMT) is a rare intermediate tumor that exhibits both benign and malignant behaviors. Whether IMT is an inflammatory or a neoplastic disease remains controversial, and there is currently no standard treatment for this disease. The treatment strategies include surgical tumor removal and drug therapy; however, several patients experience tumor recurrence post-treatment. Herein, we report the endoscopic manifestations and treatment process in a case of IMT. We performed photodynamic therapy (PDT) after endoscopic tumor resection, and no recurrence was found in the patient's re-examination a year later. This indicates that PDT can improve IMT prognosis and reduce its local recurrence, signifying the therapy's potential application value for IMT.
