Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...

OBJECTIVES Ghost cell odontogenic carcinoma is a rare condition characterized by ameloblastic-like islands of epithelial cells with aberrant keratinitation in the form of Ghost cell with varying amounts of dysplastic dentina. MATERIAL AND METHODS We report a case of a 70 year-old woman with a rapid onset of painful swelling right maxillary tumor. Magnetic resonance showed a huge tumor depende...

The calcifying odontogenic cyst (COC), first described by Gorlin et al. in 1962, represents a heterogeneous group of lesions that exhibit a variety of clinicopathologic and behavioral features. COC has been categorized under two basic groups namely, cystic and neoplastic. Even after several classifications and sub-classifications, COC remains an enigma. Very few cases of ameloblastomatous COC h...

Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. Extraosseous CEOT is one of the rarest forms of this tumor, and few such cases involving the maxillary gingiva have been reported in the literature. Here we present a case that showed progressive enlargement in the left maxillary gingival area...
