Unicystic ameloblastomas may present three histological variants, where the luminal subtype of the tumor is confined to the luminal surface of the cyst and the cystic wall is totally or partially lined by ameloblastic epithelium; the intraluminal variant presents ameloblastoma nodules protruding into the lumen of the cyst and finally, in the third variant, known as mural, the cystic wall is infiltrated by ameloblastoma [5, 6].

(5) Deposition of hard tissue like dystrophic calcification or cartilage in the cyst wall of OKC is rare, and the presence of dentinlike tissue (Figure 2), even more rare, (7) can mimic other dentinoid-forming odontogenic cysts and tumors like calcifying epithelial odontogenic tumor, odontoma, ameloblastic fibro-odontoma and adenomatoid odontogenic tumor.
