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.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
