Peripheral calcifying epithelial odontogenic tumour. Report of a case

The calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour, firstly described by Pindborg in 1955. It is most commonly intraosseous. To our knowledge, only 16 cases of peripheral CEOTs have been reported in the English literature. We present a rare case of peripheral CEOT observed in a 55-year-old woman. The lesion was seen as a small, painless, soft tissue nodule on the lingual gingiva, clinically diagnosed as epulis or papilloma and subsequently proved to be CEOT histologically. A review of the pertinent reports in the literature concerning this specific lesion is included.
