Background. Inflammatory myofibroblastic tumors (IMTs) of the lung are mesenchymal tumors composed of myofibroblastic spindle cells admixed with inflammatory cells, and are occasionally difficult to distinguish from malignant tumors. Case. A 19-year-old man was found to have an abnormal shadow in the left lower lung field on chest radiography, and was referred to our hospital. Chest computed tomography (CT) revealed a well-circumscribed nodular lesion of the left lower lung lobe, that progressively increased in size over 6 months. The nodule showed increased accumulation on 18F-fluorodeoxyglucose positron emission tomography. We performed left lower lobectomy and lymph node dissection. A histological analysis of the lesion revealed IMT. Conclusion. We reported a case of IMT that progressively increased in size, and which was resected on suspicion of lung malignancy. Cases of post-surgical relapse have been reported, highlighting the necessity of follow-up.
