AIM To report a case of a non-neoplastic variant of calcifying odontogenic cyst (COC) with the lining epithelium showing ameloblastomatous proliferation and capsule exhibiting features of a cholesterol granuloma. The importance of delineating this histologic variant from unicystic ameloblastoma and the formation of cholesterol granuloma in this variant is discussed. BACKGROUND Calcifying odon...
Calcifying cystic odontogenic tumor (CCOT) demonstrates considerable diversity in histopathology and clinical behavior. Ghost cell odontogenic carcinoma (GCOC) is the rare malignant counterpart of CCOT and it frequently arises from malignant transformation of a recurrent CCOT. In this paper, we present a case of CCOT and discuss its distinct histopathologic features in recurrence. Then, we will...
Introduction:Calcifying odontogenic cyst (COC) is an odontogenic cyst that sometimes shows aggressive behavior, while dentigerous cyst (DC) always has a benign nonaggressive course. There are evidences that myofibroblasts are involved in invasion and their role in biologic behavior of odontogenic cysts has been less understood. So, the aim of the present study was to compare th...
Calcifying odontogenic cyst (COC) is a unique odontogenic lesion with combined features of a cyst and neoplasm. This lesion shows a great diversity in its clinicopathological behavior. It may become aggressive and rarely malignant. This case is an aggressive COC of the maxilla in a young male patient which recurred after several radical surgical excisions. Eventually invading the cranium, t...
