Multiple inflammatory myofibroblastic tumor of the duodenum: case report and literature review.

Abstract

INTRODUCTION:

Inflammatory myofibroblastic tumor (IMT) is a rare low-grade malignant mesenchymal tumor, which can occur at any location, although the lung is the most commonly affected organ. It is extremely rare in the duodenum and only two cases have been reported previously. We report, to our knowledge, the first case of multiple neoplastic lesions.

CASE REPORT:

A 20-year-old male presented with the chief complaints of intermittent right epigastric pain, nausea and vomiting. Imaging examination, electronic gastroscopy and preoperative biopsy revealed undefined lesions in the duodenum. Pancreaticoduodenectomy was performed and diagnosis of multiple IMT was confirmed by pathological biopsy of the excised tumor. A satisfactory outcome was proved by the follow-up 1 year after curative operation.

CONCLUSION:

IMT can be diagnosed by histological examination and immunohistochemical test after surgical resection. Patients can benefit from radical resection with favorable prognosis.
