- Abstract: Inflammatory myofibroblastic tumors (IMTs) of the duodenum are exceptionally uncommon, and their epidemiologic and clinical characteristics remain poorly defined because of the limited number of reported cases. We previously reported a case of duodenal IMT in the Korean Journal of Gastroenterology in 2018, with follow-up data available only up to 12 months. IMTs typically behave in a benign manner, but they may occasionally demonstrate local invasiveness and recurrence; therefore, achieving complete surgical excision is crucial, followed by long-term surveillance. In the present manuscript, we provide a subsequent long-term follow-up report of the same patient, offering an extended 88-month postoperative course and additional radiologic and pathologic details not included in the earlier publication. This follow-up report highlights the long-term benign behavior of the tumor despite positive surgical margins and anaplastic lymphoma kinase (ALK)-negative immunohistochemistry, contributing meaningful information to the scarce literature on adult duodenal IMTs.
