Abstract

Iinflammatory myofibroblastic tumor(IMT) is a benign chronic inflammatory mass composed of proliferative myofibroblasts. It is a space occupying lesion which could potentially covert to malignant tumor. Treatment guideline of the disease has not been established due to its rarity. We demonstrate a 60-year old male who had surgical excision for IMT of the cervical esophagus. During the follow-up period, he revealed recurrent tumor which showed sarcomatous change with distant metastasis. We reported this rare case with review of the literature.
