Rare Benign Inflammatory Tumor of Esophagus Masquerading as Malignancy

초록

Inflammatory myofibroblastic tumors are mesenchymal neoplasms with intermediate biological potential. They tend to affect the lungs and abdominopelvic area but rarely occur in the esophagus. Only a few cases of esophageal inflammatory myofibroblastic tumors have been reported in the English literature. Herein, we report an esophageal inflammatory myofibroblastic tumor masquerading as an esophageal cancer. A 39-year-old woman complained of progressive dysphagia, and esophagogastroscopy revealed a 5-cm tumor in the lower esophagus. Ivor-Lewis surgery was performed, and the tumor was diagnosed as an inflammatory myofibroblastic tumor; the patient was successfully treated with surgery.
