Background:
Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor, which can develop in nearly all anatomical locations. It is extremely rare in the duodenum and only seven cases have been reported previously.These lesions are of unknown etiology characterized by proliferation of myofibroblastic with an inflammatory infiltrate. It is considered a tumor of borderline malignancy.
Objective:
We report the first case described of IMT located isolated in the third duodenal portion, which develops as a massive intestinal bleeding in a 14 years old girl.
Results:
Complete surgical excision was successful and after 36 months of follow up the patient is asymptomatic.

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...
