Ameloblastomatous Calcifying Cystic Odontogenic Tumor: A Rare Histologic Variant

In agreement with the new classification of the world health organization(who) 2005, calcifying odontogenic cyst (coc) or calcifying cystic odontogenictumor (ccot) is an uncommon developmental odontogenic lesionthat demonstrates histopathologic diversity. predominantly, it occurs in theanterior region of the mouth and in the second and third decades of life.odontogenic tumors such as ameloblastoma have been reported to beassociated with ccot. in this paper, we report a case ofameloblastomatous ccot in a boy with involvement of mandibular ramusanextremely rare histologic variant. the microscopic examination revealeda ccot; ghost cell within ameloblastic islands in the connective tissuewall was observed.
