Abstract
Fibro-osseous lesions are a group of diseases characterized by replacement of normal bone tissue for benign fibrous tissue containing different amounts of mineralized material. The most frequent lesions are fibrous dysplasia, cemento-ossifying fibroma and cemento-osseous dysplasia. In the literature, classification and terminology of these entities remain confusing and controversial, since these lesions show some clinical and morphologic similarities. Cemento-ossifying fibroma is a benign neoplasia that belongs to the group of fibro-osseous lesions. It is characterized by well delimited growth and occasionally is encapsulated, presenting changeable amounts of mineralized tissue similar to the bone and cementum. They are uncommon lesions that tend to occur during the 3rd and 4th decades of life, mainly in females and preferentially in the mandible. The aim of this work is to describe and discuss a clinical surgical case of symptomatic cemento-ossifying fibroma.
Keywords

Resumo
As lesões fibro-ósseas constituem um grupo de patologias caracterizadas pela substituição de tecido ósseo normal por tecido fibroso benigno contendo quantidades variadas de material mineralizado. A displasia fibrosa, o fibroma cemento-ossificante e a displasia cemento-óssea são as mais frequentes. Na literatura, a classificação e a terminologia das lesões fibro-ósseas apresentam-se ainda confusas e controversas, pois essas patologias exibem, frequentemente, características clínicas e morfológicas muito semelhantes. O fibroma cemento-ossificante é uma neoplasia benigna que faz parte do grupo das lesões fibro-ósseas. Caracteriza-se por crescimento bem delimitado e eventualmente encapsulado, apresentando quantidades variáveis de tecido mineralizado semelhante ao osso e ao cemento. São lesões incomuns, que tendem a ocorrer durante a terceira e a quarta décadas de vida, com uma predileção pelo gênero feminino, sendo a mandíbula o sítio de maior ocorrência. Este trabalho tem por objetivo descrever e discutir um caso clínico-cirúrgico sintomático de fibroma cemento-ossificante.
