A rare case of calcifying cystic odontogenic tumor

Calcifying odontogenic cyst is a rare odontogenic cyst. It was described by Gorlin in 1962 and is also called as Gorlin’s cyst. Ghost cells in the epithelium are the hallmark of Gorlin’s cyst. A 25 year old male patient complained of a painless swelling in his lower anterior teeth region which was present for the past 3 years. It was slow growing with absence of infiltration, soft in its center and bony hard in its periphery, radiograph showing multilocular radiolucency, with associated root resorption, tooth displacement. Histopathological examination revealed a cystic lesion, lined by odontogenic epithelium and amorphous eosinophilic round or oval structures suggestive of ghost cells were seen within the epithelium. A long standing multilocular radiolucent lesion in the mandible crossing the midline with clinical features imitating anameloblastoma and odontogenic keratocyst was later diagnosed as a Gorlin’s cyst with histological evidence
