A Rare Cause of Chronic Dysphagia: Pulmonary Inflammatory Myofibroblastic Tumor with Distal Esophagus Invasion

Abstract

BackgroundInflammatory myofibroblastic tumor (IMT) is rare intermediate tumor, which happens mostly in children and young adults.Case presentationReported is the successful treatment of a 29-year-old man presented with progressively dysphagia and weight loss. No other abnormal symptoms were observed. The contrast enhanced computed tomography (CT) revealed a dumbbell-shaped lesion between lung and esophagus. Finally, it was pathologically diagnosed as pulmonary IMT invading to the distal esophagus after operation. The patient underwent en bloc esophagectomy and left lower lobectomy, and was discharged on 10th postoperative day.ConclusionIMT is a rare lesion that usually occurs in the lung, but pulmonary IMT with distal esophagus invasion has not been described previously. Discriminating untypical symptom, completed resection, pathological expertise and closed follow-up will reach the successful diagnosis and treatment.
