Odontogenic keratocyst has been renamed as the World Health Organization in 2005. It is a benign intraosseous neoplasm of the jaw. They develop from the dental lamina remenants in the mandible and maxilla. Keratocystic odontogenic tumor is of particular interest because of its recurrence rate and aggressive behavior. We present a case in a middle aged lady patient.

Keratocyst Odonogenic Tumor (KCOT) is a benign odontogenic tumor with aggressive behavior and a high recurrence rate [1,2]. In the 2005 edition of the World Health Organization Classification of the Head and Neck Tumors, the odontogenic keratocyst was reclassified from a cystic to a neoplastic lesion, and the term “keratocystic odontogenic tumor” (KCOT) was coined [3]. The KCOT contributes approximately 11% of cysts of the jaws & is most commonly located in the mandibular ramus & angle [4]. Most common site is the mandibular third molar region. Remnants of odontogenic epithelium persisits in oral tissues after odontogenesis is complete and a variety of tumor and cysts may arise from these remnants [5].
