Keratoameloblastoma - a rare hybrid odontogenic tumor

The hybrid odontogenic neoplasms are rarities. the histologic features of these tumors are often identical to other individually well established odontogenic neoplasms. numerous odontogenic cysts and tumors originate from the dental lamina. therefore,a possibility of neoplastic change,in these ameloblastomatoid islands cannot be ruled out completely. the clinical presentation of these tumors is variable,ranging from cysts to neoplasms showing varying degrees of aggressive behavior. most combined tumors contain features of one of the odontogenic tumors in combination with other odontogenic tumor. we present a rare hybrid lesion of an ameloblastoma with in odontogenic keratocyst arising from the mandibular molar region in a 25-year-old male.
