Inflammatory Myofibroblastic Tumor of the Lung: A Case Report.

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor classified as an intermediate malignancy that rarely metastasizes. The most common site for IMTs is the lung, though they can develop in various other anatomical locations. Pulmonary IMTs are more common in children and adolescents and are infrequently diagnosed in adults. This case report describes a 49-year-old woman with a history of breast cancer previously treated with subtotal mastectomy and chemotherapy who developed an IMT in the lung. This case emphasizes the rarity of the disease and the associated clinical challenges when managing such cases.
