Abstract :
In agreement with the new classification of the World Health Organization (WHO) 2005, calcifying odontogenic cyst (COC) or calcifying cystic odont-ogenic tumor (CCOT) is an uncommon developmental odontogenic lesion that demonstrates histopathologic diversity. Predominantly, it occurs in the anterior region of the mouth and in the second and third decades of life.
Odontogenic tumors such as ameloblastoma have been reported to be associated with CCOT. In this paper, we report a case of ameloblastomatous CCOT in a boy with involvement of mandibular ramus- an extremely rare histologic variant. The microscopic examination revealed a CCOT; ghost cell within ameloblastic islands in the connective tissue wall was observed.
