“…IMT has been referred to as in ammatory pseudotumor, pseudosarcomatous myo broblastic proliferation, in ammatory sarcoma, plasma cell granuloma, and in ammatory myohistocytic proliferation [1]. IMT mostly occurs in younger people and is located in the lungs in the general population, although other less common sites have gradually been reported in recent years, such as liver, pancreas, pharynx, spinal canal, and retroperitoneal space [1,2,3,4]. Nowadays, we are used to thinking of IMT as a low-grade malignant tumor with pathological features of proliferation of broblastic-myo broblastic cells with in ammatory in ltration, and the potential of local recurrence but a low risk of distant metastases [5].…”
