[Florid cemento-osseous dysplasia: a poorly recognized entity. Apropos of 5 cases].

We present five cases of florid osseous dysplasia observed in our department. There has been some confusion as to the terminology of this entity. We present here a review of the literature and outline the histological classification among odontogenic tumors as well as their epidemiology. The orthopantomogam is the mainstay radiological exploration, sometimes in association with a CT-scan. There are three main differential diagnoses: Paget's disease, Gardner's syndrome located in the maxillofacial area and diffuse sclerosing osteomyelitis. Asymtomatic forms motivate therapeutic abstenstion. When inflammatory, infectious or morphological complications appear, treatment relies on surgery in combination with long-term antibiotic regimens.
