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...

Dentinogenic ghost cell tumor (DGCT) is an uncommon locally invasive odontogenic tumor regarded by many as a variant of calcifying odontogenic cyst. The peripheral variant of this clinical rarity appears as a well-circumscribed mass mimicking a nonspecific gingival enlargement. Microscopic appearance of odontogenic epithelium admixed with focal areas of dentinoid formation and sheets of ghost c...

BACKGROUND AND AIM: The calcifying epithelial odontogenic tumor (CEOT) is a rare entity described by Pindborg and represents < 1% of all odontogenic tumors. Nearly 200 cases of this neoplasm have been reported to date. It mostly occurs in the posterior mandible associated with an impacted tooth, most often a mandibular molar. Patients are usually between 30 and 50 years of age, with no sex pred...

Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopatho...

Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor which is characterized by the presence of islands and sheets of epithelial cells, amyloid like material and calcifications. These calcifications have a concentric lamellar pattern because of which they have been known by some as liesegang rings. However, classic liesegang rings seen in other extragnathic sit...

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.
