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 unus...

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm that accounts for approximately 1% of all odontogenic tumors. Its origin is controversial as well as its true malignant potential. A case of an advanced CEOT associated with an impacted right second molar in the mandible of a young black female patient is presented. Computed tomography imaging, radiographic...

Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign, locally aggressive odontogenic epithelial tumor that affects the jaws. Although there are numerous reports on the variants of CEOT, occurrence of clear cells with complete absence of calcification has been a rarity. Histochemical analysis of tumor cells revealed glycogen granules with PAS staining, with absence of CD 1a staining ...

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...

The calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. At that time, it was classified as a cyst related to the odontogenic apparatus, although it was later renamed as a calcifying cystic odontogenic tumor by the WHO calcification in 2005 due to its histological complexity, morphological diversity and aggressive proliferation [2]. Here, we describe a case of a calcifying c...

BACKGROUND Pigmented intraosseous odontogenic lesions are rare with only 47 reported cases in the English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly known as calcifying odontogenic cyst, is the most common lesion with 20 reported cases. METHODS A case of pigmented calcifying cystic odontogenic tumor associated with odontoma occurring at the mandibular cani...
