Abstract
Calcifying Epithelial Odontogenic Tumor (CEOT), also known as Pindborg tumor, is a rare odontogenic benign tumor. It was first reported by Thoma and Goldman in 1946 and defined as an independent tumor by Pindborg in 1957. Herein, we reported a CEOT case involving most of the mandible after I-125 implantation in a 53-year-old man. We cooperated with governmental and hospital departments to resect the tumors, reconstruct the mandible with a fibular flap graft, and properly dispose of the radioactive particles.

Abstract
Calcifying epithelial odontogenic tumor (CEOT), or Pindborg tumor, is infrequent and accounts for less than 1% of all odontogenic tumors. It is benign and usually asymptomatic but displays locally infiltrative and expansile behavior. Synchronous lesions affecting the jaws are exceedingly rare. We present a case of synchronous CEOTs affecting the maxilla and mandible and describe the clinical, radiographic, histologic, and immunohistochemical features. We further review five cases previously described in the literature.

Abstract
Calcifying epithelial odontogenic tumor (CEOT) is a rare neoplasm, which accounts for < 1% of all odontogenic tumors. CEOT occurs more frequently in adults with a peak incidence in the 5th decade of life and is extremely rare in the pediatric population. We present a case of a 13-year-old girl who was found to have a mandibular CEOT. We summarize the radiological features, pathological findings, clinical management and literature review focusing on this entity in children.

Abstract
Calcifying Epithelial Odontogenic Tumour (CEOT) or Pindborg tumour is a rare odontogenic tumour of epithelial origin. They constitute less than 1% of odontogenic tumours. Intra-ossseous variant of CEOT are more common compared to extra-osseous variant. Although benign, these can exhibit deceptively aggressive presentation. Here we report a rare case of CEOT in a 36-year-old female patient who presented with aggressive intra-osseous lesion with cortical breach and exuberant soft tissue proliferation. The lesion was treated with resection and reconstructed with titanium reconstruction plate.

Abstract
Several molecular pathways have been shown to play critical roles in the pathogenesis of odontogenic tumors. These neoplasms arise from the epithelial or mesenchymal cells of the dental apparatus in the jaw or oral mucosa. Next generation genomic sequencing has identified gene mutations or single nucleotide polymorphisms associated with many of these tumors. In this review, we focus on two of the most common odontogenic tumor subtypes: ameloblastoma and keratocystic odontogenic tumors. We highlight gene expression and protein immunohistological findings and known genetic alterations in the hedgehog, BRAF/Ras/MAPK, epidermal growth factor receptor, Wnt and Akt signaling pathways relevant to these tumors. These various pathways are explored to potentially target odontogenic tumors cells and prevent growth and recurrence of disease. Through an understanding of these signaling pathways and their crosstalk, molecular diagnostics may emerge as well as the ability to exploit identified molecular differences to develop novel molecular therapeutics for the treatment of odontogenic tumors.

Abstract
Calcifying epithelial odontogenic tumor (CEOT) is a locally aggressive, rare benign odontogenic neoplasm that accounts for <1% of all odontogenic tumors. It was first described by a Dutch pathologist Jens Jorgen Pindborg in 1955. It is most often located in the posterior mandible. The tumor usually appears between the second and sixth decade of life and has no gender predilection. It is slow-growing neoplasm with a recurrence rate of 10-15% and with rare malignant transformation. Early diagnosis is essential to avoid oro-maxillofacial deformation and destruction. CEOT is rarely reported in India. We, herewith present a rare case of CEOT with unusual features associated with an impacted right third molar in the posterior mandible of 35 years male, with an emphasis on clinical, radiographic, histopathology and immunohistochemical features.

Abstract
Calcifying epithelial odontogenic tumor (CEOT) is an uncommon odontogenic tumor with well-known histopathological features and a challenging treatment plan. Although some investigators advocate conservative approach as the treatment of choice, others believe in radical surgical excision to avoid recurrence or malignant transformation. The main objective of this case report is presenting an unusual destructive recurrence of CEOT after 8 years in a 34-year-old woman, and discussing an effective treatment plan for this tumor.

Abstract
Calcifying epithelial odontogenic tumor (CEOT) is a solid, locally aggressive, benign odontogenic neoplasm characterized by sheets and nests of polyhedral epithelial cells exhibiting eosinophilic and less often clear cytoplasm, occasional nuclear pleomorphism without mitotic activity, calcifications, and deposits of amyloid. A cystic variant has been reported only twice. Herein, we present an additional example of cystic CEOT occurring in a 31-year-old male and featuring clear cell epithelial lining with deposits of amyloid and osteodentin.

Abstract
We report a case of an asymptomatic sclerosing odontogenic tumor in a 31-year-old woman. Radiologically, the tumor was well circumscribed, was predominantly radiolucent, and had a peripheral sclerotic margin. Histopathologically, the tumor showed small clusters, strands, and cords of small to medium-sized epithelial tumor cells in a sclerotic collagenous stroma. Immunohistochemically, the tumor cells were positive for broad-spectrum cytokeratins (CKs) (CK7, CK5/6, CK19, and CAM 5.2) and p63. Membranous staining for E-cadherin was present. There was weak to moderate nuclear expression of p16 in 30% of cells. Rare tumor cells were positive for p53. Progesterone receptors were expressed in about 60% of the tumor cells. The proliferative activity (Ki-67) was approximately 2%. A molecular genetic (fluorescence in situ hybridization) study showed no EWSR1 (EWS RNA-binding protein 1) gene rearrangement. No recurrence or metastatic events have been documented at 1-year follow-up. This tumor represents a classification dilemma mainly between epithelial-rich central odontogenic fibroma and the so-called sclerosing odontogenic carcinoma.

Abstract
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 region of the left mandibular body with hyperdense areas inside and was associated with element 37. An incisional biopsy of the lesion was performed and the histopathological analysis revealed the presence of layers of epithelial odontogenic cells that formed prominent intercellular bridges. A large quantity of extracellular, eosinophilic, and amyloid-like material and an occasional formation of concentric calcifications (Liesegang rings) were also found. The histopathological diagnosis was a Pindborg tumor. Resection of the tumor with a safety margin was performed and after 6 months of follow-up there has been no sign of recurrence of the lesion.
