Odontogenic keratocyst with metaplastic epithelium: A case report.

Correct treatment begins with correct diagnosis. Arriving at a correct diagnosis require knowledge skill and art. Because many diseases have similar symptoms, the clinician must be astate in determining the correct diagnosis.[1] One lesion mimicking the other poses the diagnostic dilemma. Periapical lesions resulting from necrotic dental pulp are among the most common pathologic conditions within the alveolar bone.[2] Odontogenic cysts of the jaws include various pathological entities. Keratocystic odontogenic tumour (KCOT) is defined as "a benign uni- or multicystic, intraosseous tumour of odontogenic origin, with a characteristic lining of parakeratinized stratified squamous epithelium and potential for aggressive, infiltrative behaviour." In relation to OKC, there are two significant diagnostic issues. Firstly, they commonly show active epithelial growth which has prompted the belief that they should perhaps be regarded as neoplasm rather than a cyst. Secondly, they are known to occur in two fashions solitary (or sporadic) and as part of the BCNS.[3] The aggressive clinical behavior and frequent recurrence following curettage has been the focus of several studies, which indicated that the odontogenic keratocyst epithelial lining may have some intrinsic growth potential.[4] In light of the epithelial behavior here, we present a case of odontogenic keratocyst with metaplastic epithelium attributed to the presence of inflammation.
