Hereditary familial polyposis and Gardner's syndrome: contribution of the odonto-stomatology examination in its diagnosis and a case description. (1/17)
Familial Adenomatous Polyposis (FAP) and its phenotype variant, Gardner's syndrome, constitute a rare autosomal dominant inherited disorder. They are characterised by the development, generally during the second and third decades of life, of multiple adenomatous polyps in the colon and rectum. These polyps have a high risk of subsequently becoming malignant, which normally occurs in the third and fourth decades of life. The phenotypical features of FAP can be very variable. As well as colorectal polyps, these individuals can present with extra-colonic symptoms, among which are particularly: gastro-duodenal polyps, dermoid and epidermoid cysts, desmoid tumours, congenital hypertrophy of the retinal pigment epithelium, disorders of the maxillary and skeletal bones and dental anomalies. In this paper the most important aspects of this syndrome are reviewed, showing an example based on a well documented clinical case. The importance of odonto-stomatological examinations should be pointed out, among others, as a means of reaching a presumptive diagnosis, whose confirmation is vital to the patient.

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.

Only three Indian patients of florid cemento-osseous dysplasia have been reported (less than 2%), according to the review of recent literature (2003). This makes the occurrence of FCOD a relatively rare phenomenon. The age group may vary from 19-76 years and typically presents in the fourth and fifth decade. In most of the cases, patients do not have family history of the disease. We report two cases showing classic radiologic features. The diagnosis of our cases were made radiographically.

Cementoma is a very rare odontogenic neoplasm of mesenchymal origin. Clinically, in 3 horses, multiple bony enlargements of the upper and lower jaw extending into the oral cavity were observed. Radiographically, multiple, well-circumscribed, radiopaque masses surrounding the roots of the upper and lower incisors or an upper premolar tooth were present. Due to malocclusion and local pain, single teeth were extracted in each case. Grossly, a hard grayish-white mass surrounding the root of the incisors and the premolars was identified. Histopathologically, the tumors consisted of excessive deposition of cementum-like tissue. Cells, resembling cementoblasts, lined irregularly shaped lacunae, which were present in the tumor tissue, and showed minimal cellular pleomorphism. Mitotic figures were not present. Macroscopically and histologically, all 3 equine cases displayed great similarities to cementomas in other species. However, due to their high degree of differentiation, hypercementosis must be considered as a differential diagnosis. (+info)Florid cemento-osseous dysplasia: a case report. (5/17)

(+info)Cementoma is a benign (non-cancerous) tumor that primarily affects the jaw bones, particularly the lower jaw (mandible). It is characterized by the growth of abnormal cementum-like tissue within the bone. Cementum is a hard tissue that covers the roots of teeth and helps anchor them to the jawbone.
There are different types of cementomas, including:
1. Periapical cemental dysplasia (PCD): This type of cementoma usually affects the anterior region of the lower jaw and is often associated with non-vital teeth. It typically presents as a small, radiopaque (dark) area on an X-ray.
2. Florid cemento-osseous dysplasia (FCOD): FCOD is a more widespread form of cementoma that affects multiple areas of the jawbones. It primarily affects middle-aged women and can cause significant bone remodeling, leading to radiopaque lesions on X-rays.
3. Gigantiform cementoma: This rare, aggressive type of cementoma typically affects children and adolescents. It can cause rapid bone growth and expansion, resulting in facial deformities and functional impairments.
4. Ossifying fibroma: Although not strictly a cementoma, ossifying fibroma shares some similarities with these tumors. It is characterized by the formation of both bone and cementum-like tissue within the lesion.
Treatment for cementomas depends on their size, location, and growth rate. Small, asymptomatic lesions may not require treatment, while larger or symptomatic ones might need surgical removal to prevent complications such as tooth displacement, infection, or pathological fractures. Regular follow-ups with dental X-rays are essential to monitor the progression of these lesions.
