title: Intraosseous pseudocarcinomatous hyperplasia associated with chronic osteomyelitis of the mandible: report of two cases.
abstract: Pseudocarcinomatous hyperplasia (PH) is a marked proliferation of benign squamous epithelium lacking cytologic atypia and pleomorphism in response to chronic stimuli, such as inflammation, infection, irradiation, or an underlying neoplastic reaction. Intraosseous PH is a rare complication of chronic osteomyelitis and mimics squamous cell carcinoma and other squamous neoplasms. This report describes 2 cases of intraosseous PH arising in the mandible.
