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...

Calcifying Epithelial Odontogenic Tumor (CEOT) is a rare benign odontogenic tumor that was first described by Pindborg in 1955. It accounts for less than 1% of all odontogenic neoplasms. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. The radiographic appearance is characterized by unior multilocular radiolucent areas with radiopaque masses of var...

J Korean Assoc Oral Maxillofac Surg 2012;38:166-70) Calcifying epithelial odontogenic tumor (CEOT) is a rarely reported benign tumor, accounting for 0.4-3% of all odontogenic tumors. Approximately 150 cases have been reported in the literature between 1958 and 2003. The age range of CEOT varies from 8 to 92 years with mean of 36.9 years, and the occurrence of the lesion in both genders is almos...

p53 and pcna expression in keratocystic odontogenic tumors compared with selected odontogenic cysts summary: the aim of this study was to evaluate p53 and pcna expression in different odontogenic lesions regarding their different clinical behaviors. slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (rc), 23 dentigerous cysts (dc), 23 keratocystic odontogenic tumors (kc...

Pindborg tumor is a rare benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. I herein report a case of a 12 year old pediatric male patient with a painless swelling of the left maxilla of 5 months duration. Radio graphically, a well circumscribed unilocular radiolucency containing radiopaque foci associated with impacted tooth was seen, along wi...
