Mandibular primary intraosseous carcinoma arising from long-standing odontogenic keratocyst

We present a case of PIOC ex-odontogenic keratocyst (PIOC ex-OKC) in a 35-year-old male. Histopathologic examination revealed a cystic lesion with a fibrous capsule lined by corrugated parakeratinized stratified squamous epithelium resting on a basal cell layer composed of columnar cells exhibiting palisaded hyperchromatic nuclei, features consistent with OKC.
