Florid cemento-osseous dysplasia has been described as a condition that characteristically affects the jaws of middle-aged black women.
It usually manifests as multiple radiopaque cementum-like masses distributed throughout the jaws. This condition has also been
classified as gigantiform cementoma, chronic sclerosing osteomyelitis, sclerosing osteitis, multiple estenosis and sclerotic cemental
masses. The authors present a case of an uncomplicated florid cemento-osseous dysplasia in a 48-year-old black woman. Multiple
sclerotic masses with radiolucent border in the mandible were identified radiographically. Histopathologic findings revealed formation
of calcified dense sclerotic masses similar to cementum. All clinical, radiographic, biochemical and histological features were suggestive
of the diagnosis of florid cemento-osseous dysplasia.
Key Words: florid cemento-osseous dysplasia, florid osseous dysplasia, fibro-osseous lesions.

The classification of cemento-osseous lesions of
the jaws has long been a matter of discussion for
pathologists and clinicians. A review of the literature
shows a wide range of terminology used by authors to
describe what seem to be similar lesions (1-3). The
current classification of cementomatous lesions, released
in 1992 by the World Health Organization (4), is based
on age, sex and histopathologic, radiographic and clinical
characteristics, as well as location of the lesion. This
classification includes cemento-ossifying fibroma, benign
cementoblastoma and the cemento-osseous dysplasia
group, in which periapical cemental dysplasia and florid
cemento-osseous dysplasia are included.
Florid cemento-osseous dysplasia is more
commonly seen in middle-aged black women, although
it also may occur in Caucasians and Asians (5,6). In
some cases, a familial trend can be observed (7-10). The
process may be totally asymptomatic and, in such
cases, the lesion is detected when radiographs are taken
for some other purposes (11). Symptoms such as dull
pain or drainage are almost always associated with
exposure of sclerotic calcified masses in the oral cavity.
This may occur as the result of progressive alveolar
atrophy under a denture or after extraction of teeth in the
affected area (6,12).
Radiographically, the lesions appear as multiple
sclerotic masses, located in two or more quadrants,
usually in the tooth-bearing regions. They are often
confined within the alveolar bone (13). Histologically,
these lesions are composed of anastomosing bone
trabeculae and layers of cementum-like calcifications
embedded in a fibroblastic background (3,6).
