## TL;DR

This paper presents a rare case of a benign tumor in the jaw of a 28-year-old woman, highlighting its diagnosis and treatment.

## Contribution

The study reports a rare intraosseous IMT in the posterior mandible, adding to the limited literature on this condition.

## Key findings

- IMT is rare in the head and neck region and even rarer in the jaws.
- The case was diagnosed through histopathological and immunohistochemical analysis.
- Only nine similar cases have been documented in the literature.

## Abstract

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.
