Ameloblastoma ex COC: An enigma to clinicians and Pathologists

Calcifying odontogenic cyst (COC), though known for more than five decades, is always under constant ambiguity with respect to its nomenclature and classification with extreme diversity in its biologic behavior.It represents a heterogeneous group of lesions that are to be regarded as non-neoplastic, cystic, or solid masses and more frequently found in association with hamartomatous such as odontomas, Adenomatoid odontogenic cyst and other odontogenic tumors such as odontogenic fibroma and Ameloblastoma.Owing to the fewer incidences, uncertain descriptions of the COCs, specific clinical data in the literature is sparse.
