Keratocystic Odontogenic Tumour (KCOT) is one of the most controversial odontogenic tumor which remains an enigma to the world of dentistry, because of its varied biological behaviour. Initially, it was considered as a cyst but in 2005, WHO reclassified it as keratocystic odontogenic tumor because of its aggressive & recurrent behaviour & placed it in the categories of odontogenic tumors. Histopathologically it has pathognomonic appearance, but in some cases, it may show unusual histopathological presentation & can be confused with other cystic odontogenic tumors. Hard tissue formation in KCOT capsule & presence of Rushton bodies are an uncommon findings. Herewith, we report a case of 26 year old male patient with an unusual histopathologic presentation of KCOT mimicking unicystic ameloblastoma (UAB) at places & also showing Rushton bodies, areas of calcification & darkly stained cells within the capsule.
