Pathology and Genetics of Head and Neck Tumours. Cutaneous sinus tract with purulent exudates surrounded by a sclerotic skin. The location of the lesion is usually confined to the interadicular and periapical alveolar area, although an aggressive lesion may expand more inferiorly and superiorly Kawai et al.

Due to the variability oswa the appearance of fibrous dysplasia the potential differential is very long but will be significantly influenced by the dominant pattern.

After that, a reduction of purulent exudates and the improvement of the skin aspect were noted, but a mild swelling with the sinus tract persisted Fig. Early lesions are composed of cellular fibrous tissue containing variable amounts of new woven bone trabeculae with osteoblast rimming.

Fibrous dysplasia is not a form of cancer. Florid osseous dysplasia FOD is an osseous dysplasia rarely presenting in the jaws. Amorphous acellular eosinophilic matrix resembling cementum, within a fibrous stroma hematoxylin and eosin stain, magnification x World Health Organization editors.

Frequent fractures and progressive deformity may lead to difficulties with ambulation and impaired mobility. The lesion is usually asymptomatic and benign. Furthermore, Melrose noted that the classical SBC that affects teenage patients generally heals completely after surgery, whereas those associated with FOD may not do so.

It revealed the presence of an amorphous, acellular eosinophilic matrix resembling cementum, within a fibrous stroma Fig. The patient was then treated with antibiotics during 10 days. Bone and joint disease M80—M94— Fibrous dysplasia is due to developmental dysplasia and focal arrest in normal osteoblastic activity secondary to a non-hereditary mutation which results in the presence of all of the components of normal bone with a lack of normal differentiation into their mature structures.
