Abstract
The development of a squamous cell carcinoma from the epithelial lining of a keratotic odontogenic tumor (KOT) corresponds to a rare malignant neoplasm exclusive to the jawbone, also referred to as primary intraosseous squamous cell carcinoma (PIOC). It mainly affects middle-aged people, especially men (2: 1) and is usually located in the rear area of the jaw. The pathogenesis of PIOC is unknown and no predisposing factor for the development of squamous cell carcinoma of the oral mucosa has been identified. However, many authors support the hypothesis that a component of a chronic inflammatory process could prove to be the underlying factor of malignant change. We present a case of a 61-year-old male diagnosed with PIOC derived from a KOT associated with an extensive inflammatory process.
