Background: The calcifying odontogenic cyst (COC) is a rare example of a developmental odontogenic cyst. COC may clinically be diagnosed as calcifying epithelial odontogenic tumour, adenomatoid odontogenic tumour, ameloblastic fibroodontoma, complex or compound odontoma, dentigerous cyst or as other types of odontogenic cysts. Purpose: The aim is to present an unusual clinical case of COC assoc...

the calcifying odontogenic cyst (coc) is a rare odontogenic cyst. only 2% of all odontogenic cysts and tumors are coc. coc associated with odontoma (cocao) reported in 24% of cocs. cocao presents a greater incidence in female, with a ratio of 2 to 1. the highest incidence of cocao occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). here...

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...

The calcifying odontogenic cyst (COC) is a rare odontogenic cyst. Only 2% of all odontogenic cysts and tumors are COC. COC associated with odontoma (COCaO) reported in 24% of COCs. COCaO presents a greater incidence in female, with a ratio of 2 to 1. The highest incidence of COCaO occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). Here...

Calcifying odontogenic cyst is considered as a rare lesion and accounts for 1% of jaw cysts. It represents a heterogeneous group of lesions which exhibit a variety of clinicopathologic and behavioral features. It has been categorized as cyst and neoplasm. Even after several classification and subclassification, COC remains an enigma. WHO classification 2005 has reclassified the lesion as calcif...

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...

The authors present two cases of calcifying odontogenic cysts, which were confirmed by histological examination. In the first case the radiographic findings and clinical status did not indicate the presence of a calcifying odontogenic cyst. In the second case, differential diagnosis included COC. The histopathological findings showed that what appeared to be simple cases of bone translucencies ...

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...
