[Inflammatory myofibroblast tumor after surgery for primary lung cancer; report of a case]

Inflammatory myofibroblast tumor of the lung is a rare disease, and is difficult todistinguish from lung cancer. We report a case of inflammatory myofibroblast tumor which was found and resected postsurgery for lung cancer. The patient underwent right middle and lower lobectomy due to squamous cell carcinoma in right S6 of the lung. A nodular density of 15 mm in diameter was found in the right apex on computed tomography (CT) 1 year and 11 months after surgery. The right apical mass was resected by partial resection of the residual lobe and inflammatory myofibroblast tumor was diagnosed pathologically. It was a case for which recurrence or 2nd primary lung cancer was strongly suspected from the radiological findings and its rapid growth.
