Large pulmonary inflammatory myofibroblastic tumour requiring extrapleural pneumonectomy and diaphragm resection.

Inflammatory myofibroblastic tumours are rare masses that account for a very small percentage of primary lung neoplasms. They are generally considered as benign tumours but can exhibit malignant characteristics. When identified, the mainstay of their treatment is complete surgical resection. We present a case report of a large pulmonary myofibroblastic tumour that required extensive resection to achieve complete clearance.
