Quiste odontogénico calcificante asociado con odontoma complejo: Presentación de un caso y revisión bibliográfica

we report a calcifying odontogenic cyst associated with odontoma (cocao) and an included permanent canine in the superior maxilla, in a 19 year-old-man. the calcifying odontogenic cyst (coc) was first described as a distinct entity by gorlin et al in 1962. the lesion is a mixed odontogenic benign tumor, and although most of the cases present cystic characteristics, a few are of the solid type (15%), and its rare malignant transformation is well documented. the coc may occur in association with other odontogenic tumors, the most common is the odontoma, occurring in about 24% of the cases. for this association the term odontocalcifying odontogenic cyst has been suggested. radiographically is a well defined mixed lesion and histologically consists of a large cyst. in the central area of the cyst enamel and dentin deposits can be found, irregularly distributed in areas and in other parts it takes on a well defined organoid aspect. a thorough review of literature takes place and the pathogenesis is discussed.
