Focal cemento-osseous dysplasia (FCOD) is a benign fibro-osseous lesion which changes cancellous bone tissue with each fibrous tissue and. Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments. It is most common in African-American females. The three types are periapical cemental dysplasia ( common in those of African descent), focal cemento-osseous. The distinguishing histopathologic features of focal cemento-osseous dysplasia ( FCOD) (including lesions occurring in both anterior and posterior jaws) and.

Discussion Benign fibro-osseous lesions of the jaw encompass a range of clinicopathologic entities, a select few of which can be differentiated by histopathology alone. None, Conflict of Interest: The current study had several limitations.

Radiographically, the lesion has a variable appearance depending on the duration but may appear as a radiolucent to radiopaque lesion that can be well to poorly defined. The cases dysplasiq been catalogued between and in the files of the Special Procedures Clinic, operated through the discipline of oral and maxillofacial radiology at the University of Toronto, in Toronto, Ontario.

Microscopic findings parallel radiography, with older lesions exhibiting increased amounts of cementum-like material and calcifications [ 168 ]. Dentomaxillofac Radiol ; It is most common in African-American females. The posterior tooth-bearing regions are the usual sites of involvement; the maxilla is rarely affected.

In this article, the case of a year-old patient with FCOD is presented with a review of the literature. J Oral Maxillofac Surg ; We report an unusual case of concomitant occurrence of infected focal cemento-osseous dysplasia in mandible with atypical clinical presentation of two sinus openings and a radicular cyst in maxilla.

The main histopathologic differential diagnoses for FOD includes focal sclerosing osteomyelitis and ossifying fibroma [ 6 ]. History A year-old male had a history of an incidentally identified lesion in the posterior mandible.

It is asymptomatic and needs no treatment. Higher magnification revealed thick bony trabeculae without osteoblastic or cementoblastic rimming.

Focal Osseous Dysplasia

Sclerotic cemental masses of the jaws so-called chronic sclerosing osteomyelitis, sclerosing osteitis, multiple enostosis, and gigantiform cementoma. Sclerotic cemental masses of the jaws so-called chronic sclerosing osteomyelitis, sclerosing osteitis, multiple enostosis, and gigantiform cementoma.

Clinical, radiographic, biochemical and histological findings of florid cemento-osseous dysplasia and report of a case. World Health Organization Classification of Tumours. Biopsy is recommended when lesions become symptomatic, show radiological features concerning for ossifying fibroma, or occur at a site that will be used for an implant [ 5 ].

Rare disease: Focal cemento-osseous dysplasia of mandible

A key feature of FOD is its association with the periapex as well as previous extraction sites [ 24 — 6 ]. As the name implies, fibro-osseous lesions are benign entities possessing both fibrous and ossesous components, and include reactive, cemento-ossepus, and dysplastic processes [ 12 ].

Osseous cemento-osseous dysplasia of the jaws: The presence of inflammation is critical for the diagnosis of focal sclerosing osteomyelitis because this lesion can resemble several other intrabony processes that produce somewhat similar histological patterns.

In rare cases, the lesion may affect only one tooth and thus mimics an apical granuloma or a cyst.
