Infiammatory myofibroblastic tumor of the small intestine

Inflammatory Myofibroblastic Tumor (IMT), previously called inflammatory pseudotumor and plasma cell granuloma, belongs to a class of rare spindle cell lesions showing a rather unpredictable biological behavior with occasional tendency toward invasion to the surrounding tissue and Local recurrence. The lesion, as primarily described by Bahadori and Liebow in 1973, is a reactive/inflammatory process in the pulmonary system mostly occurring in children and young adults. Since then, many cases have been reported in older patients in addition to extra-pulmonary sites. Inflammatory myofibroblastic tumor (IMT) emerges as a pseudotumor with malignant manifestation (1). This inflammatory tumor is usually seen in children and adolescents. It can affect all the body organs (2). The most common localization of this tumor is in the lungs, Mesentery comes in the second place (3). The pathogenesis of this inflammatory tumor cannot be accurately recognized (4). The manifestation of disease is variable with respect to the Involved organ, and the compressive effects of tumor are generally important (5). The definitive diagnosis of this tumor is possible through surgery and pathology, and the removal of symptoms usually requires there section of the mass (6).
