PDF: Florid cemento-osseous dysplasia: a case report

The term florid cemento-osseous dysplasia (FCOD) refers to a group of fibro-osseous (cemental) exuberant lesions with multi-quadrant involvement.

FCOD is a very rare condition presenting in the jaws. These lesions are most commonly seen in middle-aged black women, although it also may occur in Caucasians and Asians, and have been entitled as sclerosing osteitis, multiple enostoses, diffuse chronic osteomyelitis and gigantiform cementoma.

The cause of FCOD is still unknown, and there is no satisfactory explanation for the reported gender and racial predilection. 

FCOD lesions have a striking tendency towards bilateral, often quite symmetrical, location, and it is not unusual to find extensive lesions in all 4 posterior (molarpremolar region) quadrants of the jaws. 

Clinically, these lesions are often asymptomatic and may present as incidental radiological findings. Symptoms such as dull pain or drainaige are almost always associated with exposure of the sclerotic calcified masses in the oral cavity.

This may emerge as the result of progressive alveolar atrophy under a denture or after extraction of teeth in the affected area involved. 

Radiographically, FCOD appear as dense, lobulated masses, often symmetrically located in various regions of the jaws. 

Computed tomography (CT), because of its ability to give axial, sagittal, and frontal views, is useful in the evaluation of these lesions. 

This paper presents the case of a patient who was diagnosed with FCOD on the basis of clinical and radiographic findings.
