Extraosseous calcifying cystic odontogenic tumor: An uncommon variant

Abstract

Odontogenic cysts comprise a diverse group of exceptional lesions derived from epithelial elements of the tooth-forming apparatus. Calcifying cystic odontogenic tumor is a rare odontogenic lesion, which represents about 2% of all odontogenic tumors and cysts. It may occur in a central (intraosseous) or peripheral (extraosseous calcifying cystic odontogenic tumor [ECCOT]) location. ECCOT in contrast to central, tends to affect the older patients, commonly located in the anterior lower jaw, is less aggressive and the recurrence is rare. Here, we report clinico-pathological and radiographic features of ECCOT located in relation to 48 (posterior lower jaw) measuring about 1 cm in the greatest diameter in a 17-year-old male.

Malignant transformation of calcifying cystic odontogenic tumour – a review of literature

“…A calcifying cystic odontogenic tumour (CCOT) is a heterogeneous group of lesions. It is a relatively rare odontogenic lesion which exists either as a cystic or a solid variant and is characterised by varied clinical, radiographical and biological features [ 1 ]. CCOT presents both central (intraosseous) and peripheral (extraosseous) locations.…”
