title: Inflammatory pseudotumor in the mandible.
abstract: Inflammatory pseudotumor (IPT) is a rare benign nonneoplastic lesion. The exact etiology of IPT remains unclear. Inflammatory pseudotumor in the maxillofacial region is exceptionally rare, and it is often mistaken for a malignancy. The diagnosis is still difficult and is based on the histological examination of the lesions composed of 3 types of inflammatory cells: histiocytes, plasma cells, and lymphocytes. Due to its feature mimicking invasive malignant tumors, we should consider this entity before we carry out radical procedures. In this short report, we will present a case of an aggressive IPT involving the mandible and a review of literatures.
