Calcifying Cystic Odontogenic Tumor: Review with Discussion

Abstract

Aim: We report a case of calcifying cystic odontogenic tumor affecting maxilla in a 48 year old male patient presented with painless extensive intraoral swelling with unilocular radiolucency and marked resorption of roots on radiographs. Summary: Calcifying cystic odontogenic tumor (CCOT) is rare developmental odontogenic pathology. The first description of lesion was given in 1962. Various terminologies and classifications have been proposed for description of the lesion. CCOT has extraosseous and intraosseous variants. Clinically it usually presents as a slow growing painless swelling of maxilla or mandible. It commonly involves anterior region of jaws, shows no gender predilection. Radiographically the lesion has variable appearance. The most common presentation is a well defined unilocular radiolucency associated with irregular calcification. Presence of ghost cells with proliferative odontogenic epithelium is the characteristic feature of the lesion. Surgical enucleation is the treatment of choice.
