floride zemento-ossäre Dysplasie
Florid cemento-osseous dysplasia is a subtype of cemento-osseous dysplasia. It is a rare condition presenting in the jaw refers to a group of fibro-osseous (cemental) exuberant lesions with multi-quadrant involvement.
Epidemiology
There may be an increased female predilection and tends to be most prevalent in the 4 to 5 decades of life.
Pathology
It is considered a reactive, non-neoplastic process confined to tooth-bearing areas of the jaws.
Radiographic features
Orthopantomogram / cone-beam CT
Radiographically, florid cemento-osseous dysplasia is characterized by multiple masses of mixed radiopaque structures. The may have a circumferential radiolucency, primarily surrounding the root apices of vital teeth, and over time with the maturation of the lesions, they tend to become increasingly radiopaque.
History and etymology
Florid cemento-osseous dysplasia was first described by Melrose et al. in 1976.
Differential diagnosis
Possible differential considerations include
- Paget disease: affecting jaw
- gigantiform cementoma
- chronic diffuse sclerosing osteomyelitis
- focal areas of fibrous dysplasia
- periapical cemental dysplasia
- gnathic osteosarcoma (on rare occasions)
