When lesions in soft tissue reach the gingival margin, they can produce aesthetic defects during its permanence and after its removal. Periodontal plastic surgery allows the correction of the gingival contour using different techniques. This paper is a case report of a peripheral ossifying fibroma removal in the interproximal area of teeth 21 and 22 in addition to root coverage of the affected area through two surgical phases: keratinized gingival tissue augmentation surgery with free gingival graft concurrent with removal of the lesion and, in a second stage, root coverage by performing coronally advanced flap technique with a follow-up of five years...

Central cemento-ossifying fibroma is characterized by the combined production of osteoid and cementoid tissue. Radiographically, this lesion is presented as an outlined cortical and variable radiopaque spots, also can be present complete radiolucent or different degrees of radiopacity. The recommended treatment is curettage or enucleation, and the recurrence rate is less than 5%. Considering that surgical treatment is invasive, mainly in large lesions, this study aims to report a patient in whom conservative treatment was carried out by involving the preservation of teeth, with a long-term follow-up...

Multiple non-ossifying fibromas (MNOFs) occur either isolated or in association with other anomalies, are usually localized in the long bones of the lower limbs, may be radiographically confused with other skeletal lesions, and tend to heal spontaneously with the completion of the skeletal growth. Segmental distribution, either monomelic or polymelic and ipsilateral, is rare and commonly observed in the context of developmental diseases known as "RASopathies", which are caused by mutations in genes that encode components or regulators within the Ras/mitogen-activated protein kinase signaling pathway...

Oral manifestations of severe secondary hyperparathyroidism include maxillary and mandibular deformities, brown tumors, dental abnormalities, and metastatic calcification of soft tissues. We report on a chronic hemodialysis (HD) woman with severe, uncontrolled secondary hyperparathyroidism and a painful, nontender mass in the floor of her mouth. The most likely clinical diagnosis was a bone tumoral lesion of the oral cavity, secondary to renal osteodystrophy. Unexpectedly, pathological examination showed characteristic features of ossifying fibroma (OF) of the jaw, a rare, benign fibroosseous lesion characterized by the replacement of normal bone by collagen and fibroblasts containing varying amounts of mineralized substance...

Cemento-ossifying fibroma (COF) is a fibro-osseous lesion or non-odontogenic tumour that affects craniofacial bones. These lesions are included in the spectrum of fibro-osseous lesions arising from periodontal ligament cells, which can deposit combination of cementum and bone surrounded by fibrous tissue. It clinically, macroscopically and radiologically resembles complex composite odontome and can be differentiated only on the basis of histopathology. They usually occur solitarily as a painless and expansile spherical or ovoid jawbone mass that may displace the roots of adjacent teeth...

Focal gingival enlargements are a diverse group of lesions with almost similar clinical presentation but varied etiology and histopathology. The actual cause of peripheral ossifying fibroma (POF) has been debated over many years. POFs are usually seen in childhood and younger ages. There is a slight female predilection. It is usually localized, rarely generalized. Usually, the treatment option is only surgical excision with minimal chances of recurrence. Here, we report a case of POF of the right maxillary posterior region with a review of literature...

INTRODUCTION: Cancer in the parathyroid gland is rare, but parathyroid cancer is occasionally seen in relation to genetic abnormalities. Due to a limited amount of evidence, the optimal handling of these cases is not clear. Furthermore, the presence of a malignant parathyroid tumor is rarely known at the time of the initial operation; therefore, re-operations are often necessary. The aim of this study was to present the case of a patient with a previously diagnosed jaw tumor and parathyroid carcinoma that presents as a recurrence of hyperparathyroid hypercalcemia...

BACKGROUND: The tumor suppressor gene CDC73 was found to be associated with hyperparathyroidism-jaw tumor syndrome (HPT-JT), which is characterized by parathyroid adenoma or carcinoma, ossifying fibroma (OF) of the jaws, and renal and uterine lesions. Mutations in CDC73 have also been frequently detected in sporadic parathyroid carcinomas and renal tumors. However, the prevalence and range of CDC73 mutations in sporadic OFs have not been established. METHODS: We directly sequenced coding and flanking splice junctional regions of CDC73 in 40 cases of sporadic OF of the jaws...

: Hyperparathyroidism jaw tumour syndrome is a rare autosomal dominant inherited endocrine neoplasia syndrome, which predisposes carriers to develop a triad of multiple ossifying fibromas of the maxilla and mandible, parathyroid adenomas and carcinomas (with consequent hyperparathyroidism) as well as renal and uterine tumours. The prevalence of this condition is unknown. Patients typically present initially with symptoms and signs of a jaw tumour. A high index of suspicion is required for the underlying diagnosis to be recognised, enabling appropriate management of jaw lesions, treatment of hyperparathyroidism, if present, as well as early detection of malignant disease and screening of family members...

Ossifying fibromas of the maxillofacial bones are an uncommon form of benign neoplasm usually treated by surgical excision. Up to 30% of patients with hyperparathyroidism-jaw tumor syndrome, a rare form of multiple endocrine neoplasia resulting from autosomal dominant inactivating mutation of the Hrpt2 tumor suppressor gene, initially present with ossifying fibromas. Coincident hypercalcemia because of the presence of parathyroid adenoma is common in these patients, of whom 15% may have or may develop parathyroid carcinoma...

Ossifying fibroma is a rare benign osteogenic neoplasm arising from undifferentiated cells of the periodontal ligament. Ossifying fibroma have a well-defined border that differentiates it from fibrous dysplasia clinically; these tumors manifest as a round or ovoid, expansile, painless, slow-growing mass may displace the roots of adjacent teeth and also cause root resorption. A variety of approaches for resection of the maxilla have been described. Most involve the use of facial and lip-splitting incisions to gain wide access...

A cutaneous proliferative mass was identified arising from the caudal peduncle of a captive neon tetra fish (Paracheirodon innesi). The lesion was histologically consistent with an ossifying fibroma (OF), a fibro-osseous proliferative lesion typically identified in the jaws or tooth-associated supportive tissues of mammals. Although it has been previously reported, there is no recent report of this lesion occurring in a fish. This is the first report of a cutaneous ossifying fibroma in a characin fish. The authors speculate on the pathogenesis of this lesion, which may have arisen from the scale-associated mesenchymal tissues...

INTRODUCTION: Giant cell tumor of bone (GCTOB) is a locally aggressive neoplasm that accounts for 5% of all primary bone tumors. This tumor overlaps in histopathologic and radiographic presentations with different malignant, benign, and metabolic giant cell-rich lesions. The purpose of this study is to evaluate p63 expression status in giant cell tumor of bone in comparison with other giant cell-rich lesions. MATERIALS AND METHODS: In a cross-sectional study we examined immunohistochemical expression of p63 in a series of 100 giant cell-rich bone lesions, including 31 giant cell tumors of bone, 14 osteosarcomas (including 3 giant cell-rich variants), 18 aneurysmal bone cysts (including one solid variant), 8 non-ossifying fibromas, 17 chondroblastomas, 8 tenosynovial giant cell tumors, and 4 brown tumors...

BACKGROUND: Ossifying fibroma is a rare benign bone tumor that occurs mostly in the jaw, but also affects paranasal sinuses and fronto-ethmoidal complex. Occipital bone is an extremely rare location for these tumors; only two cases have been reported. METHODS: We present the first case reported as psammomatoid subtype of ossifying fibroma, according to the 2005 WHO classification. An 18 years old male patient with infratentorial tumor, in the occipital bone, that produces mass effect over the cerebellum...

Cherubism is a rare disorder with autosomal dominant inheritance. It is classified as a benign fibro-osseous lesions and may involve either facial bone. Its typical dentofacial deformities are caused by mutations in the SH3BP2 gene. The protein encoded by SH3BP2 had a significant role in the regulation of osteoblasts and osteoclasts. Accordingly with the radiological findings, differential diagnoses includes fibrous dysplasia, giant cell granuloma, osteosarcoma, juvenile ossifying fibroma, fibrous osteoma, odontogenic cyst and hyperparathyroidism...

OBJECTIVE: The endoscopic modified Lothrop procedure is mainly used for refractory frontal sinusitis. However, we have used it as an access procedure to facilitate treatment for an extended range of additional frontal sinus pathologies. METHODS: A retrospective review of patients who underwent the endoscopic modified Lothrop procedure for 'alternative' frontal sinus pathologies was conducted. Patient data were reviewed. The main outcome parameter measured was signs of recurrence...

Osteofibrous dysplasia or ossifying fibroma is an uncommon benign fibro-osseous lesion of childhood, commonly described in the maxilla and the mandible. Among long bones, it usually presents in the tibia as a painless swelling or anterior bowing. Ossifying fibroma of clavicle has never been reported in English literature, to the best of our knowledge. Here, we would like to present an unusual case of osteofibrous dysplasia of clavicle clinically mimicking chronic osteomyelitis.
