Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign lesion. A case of CEOT in the left mandible of a 46-year-old man is presented. This case is exceptionally unusual because it was left untreated for 10 years, indicating in some way the course of the tumor. Histologic findings both at the time of first diagnosis and at the final treatment 9 years later were identical.

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.

Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. Extraosseous CEOT is one of the rarest forms of this tumor, and few such cases involving the maxillary gingiva have been reported in the literature. Here we present a case that showed progressive enlargement in the left maxillary gingival area...

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm; it comprises only 0.6 % to 1.7 % of all odontogenic tumors. Most cases involve the posterior mandible; there have been few reported maxillary cases. Although its biological behavior is relatively indolent, maxillary lesions tend to grown rapidly and not be circumscribed. Treatment of the CEOT consists of surgical remo...

Hybrid tumors are very rare tumors composed of two different tumor entities, each of which conforms to an exactly defined tumor category. A 14-year-old boy was referred for an intraosseous painless lesion with a histopathological feature of multiple odontogenic lesions including calcifying odontogenic cyst, complex odontoma and ameloblastic fibro-odontoma. The final diagnosis considered to be a...

The calcifying epithelial odontogenic tumor (CEOT), Pindborg tumor is a benign, slow growing, but locally invasive neoplasm. It is known to have a common intraosseous variant and a very rare extraosseous variant. We report an unusual case of an extraosseous variant of CEOT of unusual large size and maxillary anterior location, the treatment was planned considering the clinical, radiological and...

The calcifying epithelial odontogenic tumor (CEOT), also known as the Pindborg tumor, is a benign and rare odontogenic tumor accounting for 0.4-3 percent of all odontogenic tumors. Few reports of the incidence of this tumor exist in Iran. The most frequent location is the mandibular premolar and molar area; less frequently the lesion is found in the maxilla. In clinical features, a painless slo...
