Background and Objective: Inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. Some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. The aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inf...

inflammatory myofibroblastic tumor (imt) in the spine or paraspinal area is extremely rare. here, we report a rare case of a 56-year-old man who had pathological-proven spinal epidural imt showing a malignancy-like infiltrative feature on mr imaging with alteration of t2 signal intensity on follow-up from slightly high to low compared with initial mr imaging. to the best of our knowledge, this ...

BACKGROUND Inflammatory myofibroblastic tumor, composed of myofibroblastic spindle cells with acute and chronic inflammatory cells, is an unusual, benign solid mass that mimics a neoplastic process. METHODS We report a rare case of a patient with a laryngeal inflammatory myofibroblastic tumor. Laryngoscopy demonstrated a submucosal mass involving the right false cord. The mass was a well-enha...

Inflammatory myofibroblastic tumors are rare, and those located in the extremities without bone involvement are even rarer. We present the case of a 61-year-old Chinese male patient with an inflammatory myofibroblastic tumor of the right thigh. It was excised and a histopathologic examination revealed an inflammatory myofibroblastic tumor. This case is presented by virtue of its rare location.

An inflammatory myofibroblastic tumor, also known as inflammatory pseudotumor, is a rare neoplasm characterized by myofibroblastic spindle and inflammatory cells that cause masses in many sites of body. It is often benign, but in some cases neoplastic transformation has been reported as a result of aggressive growing. In our case, an inflammatory myofibroblastic tumor was reported by biopsy of ...

Inflammatory myofibroblastic tumor of the liver is an uncommon lesion of uncertain pathogenesis that has a unique histological appearance. Symptomatology and clinical findings in most cases suggest malignancy, and despite the advances in imaging techniques, the preoperative diagnosis of this tumor is difficult. We describe herein a case of inflammatory myofibroblastic tumor of the liver with a ...

CONTEXT Inflammatory myofibroblastic tumor is a distinctive lesion of unknown etiology. It has generally been considered a rare benign pseudosarcomatous lesion of admixed inflammatory infiltrates with myofibroblastic spindle cells. Although original case descriptions focused on the pulmonary system, it is now recognized that virtually any anatomic location can be involved. However, an inflammat...

Inflammatory myofibroblastic tumor (IMT) histologically characterized by fibroblastic and myofibroblastic proliferation with inflammatory infiltrate. The therapy adopted was Whipple's pancreaticoduodenectomy with a histological diagnosis of the inflammatory myofibroblastic tumor. The disease that should be considered as the differential diagnosis is pancreatic cancer. The diagnosis and treatmen...
