Multicystic Variant of Calcifying Cystic Odontogenic Tumor Associated With Odontome - Report of A Case And Review.

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumours. We present a case of Calcifying cystic odontogenic tumor occurring in a 15 year old boy involving an unerupted permanent canine and premolar. The tumor was multicystic in nature and was associated with a complex odontome. This article also includes an update on nomenclature and classification of ghost cell odontogenic lesions.

Keratocystic Odontogenic Tumor - A Wolf In Sheep's Clothing.

Keratocystic odontogenic tumor or Odontogenic keratocyst is a benign but one of the most locally aggressive type of developmental odontogenic cyst. Due to its invasive abilities in the bone and its high recurrence rate, it shares features of a cyst or a neoplasm and continues to riddle clinicians and researchers. Clinical and radiological expertise lies in diagnosing such lesions which present themselves as a coincidental finding in a routine out patient department. We report an unusual occurrence of a Collateral Odontogenic Keratocyst between the roots of two mandibular molars.
