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...

Calcifying odontogenic cyst is a developmental odontogenic cyst first described by Gorlin in 1962. It is considered as an extremely rare condition and shows extensive diversity in its clinicopathological appearances and biologic behavior. In this report a rare case of calcifying odontogenic cyst with ameloblastic proliferation (an extremely rare histologic variant) with one year follow – up is ...

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...

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 ...

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...

Calcifying cystic odontogenic tumor (CCOT) is a rare odontogenic lesion comprising about 2% of all odontogenic pathological changes in the jaw. Clinically presents as painless swelling of jaw, while histopathology demonstrates characteristic “Ghost” epithelial cells with a propensity to calcify. Due to its varied clinical presentation, including cystic and neoplastic forms and recurrence rates ...
