Abstract
An inflammatory myofibroblastic tumor (IMT) is a rare disease that can occur in a variety of locations, including the lung, orbit, parotid, pleura, and stomach. Despite multiple reports in various organs, a duodenal IMT is rare with limited case reports. We encountered a case of a 49-year-old male with a duodenal IMT. The patient underwent a laparoscopic wedge resection under the impression of a duodenal mesenchymal tumor, such as gastrointestinal stromal tumor, but the final diagnosis was a duodenal IMT. The patient was treated successfully with an oral nonsteroidal anti-inflammatory drug for the residual lesions. He was free of recurrence during the 12 month follow-up period.
