Cemento-ossifying fibroma is classified as an osteogenic tumor, defined as a well -differentiated tumor, occasionally encapsulated, comprising fibrous tissue. Abstract. Introduction: Cemento-ossifying fibroma is a benign fibro-osseous maxillary tumor belonging to the same category as fibrous dysplasia and. Background: Cemento-Ossifying Fibroma (COF) is considered by most as relatively rare, benign, non-odontogenic neoplasm of the jaw bones and other.

Cemento-Ossifying Fibroma- A Case Report | OMICS International
Discussion Cemento – ossifying fibroma is a benign fibro-osseous- tumor. A 35 year old female patient reported with a complaint of swelling on the lower left jaw since past 2 months [ Figure 1 ]. An attempt has been made by Endo et al. This is an open-access article distributed under the terms of the Creative Commons Attribution-Noncommercial-Share Alike 3.
Various classifications were proposed to classify these lesions, Menzel [ 6 ] gave the first description of a variant of ossifying fibroma, which was a benign fibro-osseous neoplasm, calling it as a cemento-ossifying fibroma in Can’t read the image? Occasionally bleeding occurred when he brushed his teeth.
Photomicrograph showing fibrocellular stroma with osseous trabeculae and cementoid tissue. The mineralized product probably originates from periosteal cells or from the periodontal ligament [ 6 ].
Histopathological picture had shown highly cellular fields with some calcified areas. Synchronous ossifying fibromas of the cemenyo High recurrence rates call for a thorough surgical treatment approach for such cases.
Various lesions may show clinical and radiographic resemblance to COF as mentioned above. PCOF affects both genders, but a higher predilection for females has been reported in the literature [ 4 ]. The extent to which the tumor spreads, guides surgical therapy.
J Oral Maxillofac Surg ; Although it is also important to maintain a high index ossiffying suspicion, discussion with family members should be tactful to prevent undue distress during the waiting period between differential diagnosis and definitive histopathologic diagnosis. A clinico-pathologic study of 8 tumors.
The lesion was neither fluctuant nor did it blanch on pressure, but had a rubbery consistency. The multilocular lesions were more prominent in the mandibular posterior regions and in patients younger than years. Cemento-ossifying fibroma is the term given mainly due to presence of dysmorphic round basophilic bone particles within ossifying fibroma, which have arbitrarily been called cementicles. When bone and cementum-like tissues are observed, the lesions have been referred to as cemento-ossifying fibroma [ 11 ].

Over the last several decades, fibro-osseous lesions have evolved which includes two major entities: Clinically, PCOF manifests as a pediculate or sessile nodular mass, which usually originates in the interdental papilla. High power histopathological picture showing lamellar bone with osteoblastic rimming and psammomatous-like nodules and calcifications in the fibrous stroma haematoxylin-eosin x Giant cemento-ossifying fibroma—A case report and review of literature.
J Oral Pathol Med. Fibro-osseous lesions are a heterogeneous group of benign lesions of unknown aetiology affecting the jaws and other craniofacial bones, which are characterized by the replacement of normal bone by fibrous tissue, which contains a newly formed, mineralized product [ 1 ]. Mandibular occlusal radiograph reveals a well-defined expansion of both the buccal and lingual cortical plates arising from lower right 1st molar region, with evidence of septa suggesting a multi-locular appearance and diffuse irregular radiopacity within the largely radiolucent lesion.

It commonly presents as a progressively growing lesion that can attain an enormous size with resultant deformity if left untreated. Report of a case and review of the literature. This paper attempts to diagnose a case of cemento-ossifying fibroma of the jaw not only based on clinical characteristics but also radiographic and histopathologic features as an adjunct.
This article has been cited by 1 Implant prosthetic rehabilitation with a free fibula flap and interpositional bone grafting after a mandibulectomy: Chronic irritation of the periosteal and periodontal membrane causes metaplasia of the connective tissue and resultant initiation of formation of bone or dystrophic calcification.
Cemento-ossifying fibroma of the mandible
The bone-like component is predominant lssifying of woven bone and is found in more ‘mature’ lesions 1. Endo et al attempted to distinguish COF from ossifying fibroma and fibrous dysplasias by immunohistochemistry.
A more aggressive form of COF which occurs in ceemento individuals has been designated as Juvenile cemento-ossifying fibroma [ 10 ].
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.
Cemento-ossifying fibroma of the mandible.
A year-old male patient was referred by his general dental practitioner for gingival swelling in relation 15 to 16 region. Case Report A 30 year old female patient with no other relevant medical history, reported to the department with a swelling on the right side of the face since the last 2 years with occasional pain Figure 1. Cemento-Ossifying Fibroma COF is considered by most as relatively rare, benign, non-odontogenic neoplasm of the jaw bones and other craniofacial bones characterized by replacement of normal bone by fibrous tissue and varying amounts of newly formed bone or cementum-like material, or both.
While the central variant described above is a neoplastic entity, the peripheral variant is a focal, reactive non-neoplastic growth of soft tissues, which may be composed of mature collagen, cellular fibroblastic tissue, mineralized tissue and multinucleated giant cells. A 30 year old female patient with no other relevant medical history, reported to the department with a swelling on the right side of the face since the last 2 years with occasional pain Figure 1.
These are all ossifying fibromas; those that happen to occur in the jaws should not be termed cement ossifying fibromas merely because of the presence of teeth.
