Peripheral calcifying cystic odontogenic tumor (PCCOT) is a rare odontogenic lesion, which represents about 1% of jaw cysts. Here we report clinicopathologic, radiographic and CT scan images of a new case of recurrent large PCCOT located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. In reviewing the li...

Calcifying Cystic Odontogenic Tumor (CCOT) was previously described by Gorlin et al., in 1962 as Calcifying odontogenic cyst. CCOT is a rare lesion which accounts for 2% of all odontogenic pathological changes in the jaws. One of the variants, Ameloblastomatous proliferating type of CCOT is even more rare and very few cases have been reported in the light of literature review. This case report ...

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic tumor. Here we report 3 cases of CEOT. All patients were women and the age of the patients ranged from 39-48 years. All cases were located in the maxilla. Histologically, one case was epithelial-predominant and consisted of large irregular cribriform sheets of polygonal epithelial cells, dense eosinophilic amyloid-like ...
