Intraosseous Inflammatory Myofibroblastic Tumor of the Posterior Mandible: A Rare Case with Immunohistochemical Interpretation.

Inflammatory myofibroblastic tumor (IMT), previously called an inflammatory pseudotumor, is an unusual, rare, benign, but aggressive tumor of soft tissue origin. It is histopathologically characterized by heterogeneous proliferation of myofibroblasts with admixture e of various inflammatory cells, including lymphocytes, plasma cells, histiocytes, and eosinophils. IMTs are rare in the head and neck region and are exceedingly rare in the jaws as central lesions; only nine cases have been reported in the literature. We report a case of intra-osseous IMT occurring in the posterior mandible of a 28-year-old lady with a detailed discussion of treatment, histopathological, and immunohistochemical features.
