Cemento-ossifying fibroma of the mandible A clinicopathological report Tapas K. E-mail: moc. Abstract Cemento-ossifying fibromas are rare fibro-osseous benign neoplasms that affect the jaws. They are included in the group of mesodermal odontogenic tumors and commonly present as a progressively growing lesion that might attain enormous size with resultant deformity, if left untreated. A confusion prevails on the terminology, which can only be confirmed by histopathologic evaluation. A case of cemento-ossifying fibroma involving the right mandible is described in a 30 year-old female patient.

It commonly presents as a progressively growing lesion that can attain an enormous size with resultant deformity if left untreated. A case of cemento-ossifying fibroma involving the left mandible is described in a 35 year old female patient.
The clinical, radiographic and histological features as well as surgical findings are presented. The cemento-ossifying fibroma is a central neoplasm of bone as well as the periodontium which has caused considerable controversy because of the confusion regarding terminology and the criteria for its diagnosis. Fibro-osseous lesions of the jaws have been classified by Waldron[ 1 ] and Kramer et al. However, Eversole and his co-workers in a study of 64 cases of cemento-ossifying fibroma reported a recurrence rate of as high as 28 per cent following surgical curettage of these lesions.
The latter manifests as a well delimited unilocular lesion containing variable amounts of radio-opaque material. The swelling was gradually increasing in size. It was present on the body of mandible and extended along the inferior border of the mandible up to the submandibular region. It was bony hard in consistency, and tender along the mental nerve region.
The overlying mucosa was normal in appearance. Patient also had a history of pus discharge from left ear, which resolved spontaneously. Lateral oblique radiograph revealed a well-defined radio-lucency of size approximately 6.
Computed tomography CT scan showed expansion of the buccal and lingual cortical plates of the mandible [ Figure 3 ]. Histopathological picture had shown highly cellular fields with some calcified areas. Cellular component was composed of fibroblasts arranged in different patterns. The lesion was diagnosed as a cemento-ossifying fibroma. Patient was reviewed after 2 months of surgery, and the follow up revaled that the size of the swelling had decreased and healing had taken place.
Central cementifying fibroma of maxilla
This article has been cited by other articles in PMC. Abstract Central cementifying fibroma is a bony tumor, which is believed to be derived from the cells of the periodontal ligament. Central cemento-ossifying fibroma behaves like, a benign bone neoplasm. This bone tumor consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum, or both. Central cemento-ossifying fibromas of the mandible are common; however, they are rare in the maxilla region. This tumor is most frequent between 35 and 40 years of ages. In this report we have described a year-old male with cemento-ossifying fibroma of the maxilla region with the mass that had been appeared months prior to his first referral.

Moreover, confusion exists regarding its relationship to other similar entities with various definitions and debate as to whether it is of odontogenic or nonodontogenic osseous origin , although the WHO classification currently lists it as a "bone-related tumor" 7. Occasionally, they are identified in children, in which case they are a more aggressive variant and are known as juvenile aggressive cemento-ossifying fibromas discussed separately 3,5. Teeth are often displaced by the growing mass. Other locations within the head and neck have been described 1. However, in most cases both features are present, warranting the generic term cemento-ossifying fibromas 1.
