Calcifying Epithelial Odontogenic Tumor

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region. The computerized tomography in coronal plane revealed a hypodense lesion in the posterior reg...

A clinicopathologic study on calcifying epithelial odontogenic tumor: with special reference to Langerhans cell variant

BACKGROUND Calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour, and its Langerhans cell variant is even rarer. Due to the limited number of recorded cases, the biological behaviour and histogenesis of the Langerhans cell variant of CEOT are not yet fully understood. Thus, the correlation between conventional CEOT and the Langerhans cell variant remains to be clar...

Recurrent Peripheral Calcifying Cystic Odontogenic Tumor (Calcifying Odontogenic Cyst)

  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 of the Mandible

The calcified epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign but locally aggressive lesion. Usually this tumor is located in the molar premolar region of the lower jaw. There is no sex predilection and the lesion most frequently occurs during the fourth and fifth decade of life.
