Keratinising Squamous cell carcinoma-A rarity

Abstract

Keratocystic odontogenic tumor (KCOT) is still a dilemma in the field of medical science because of its biological behavior and transformation of this benign odontogenic tumor to a carcinomatous type, which is called as odontogenic carcinoma. We are presenting here a case of squamous cell carcinoma occurring in recurrent KCOT of temporal region. The rarity of this article is the location of the lesion which is rarest at temporal region. Malignant transformation of these KCOT’s has been reported only in 15 cases in literature, the majority occurring in jaws but no case reported for lesion of temporal region. The pathogenesis of the tumor, the biologic progression, overall clinical, and histopathological features of this rare malignancy, and its management is reported and discussed.
