An emaciated, adult, free-ranging roe deer ( Capreolus capreolus ) presenting a large mandibular mass, was shot by a game warden in Sissach, Switzerland. The head of the roe deer was submitted to the Center for Fish and Wildlife Health for examination. Grossly, the mass consisted of a 6 × 7 × 4 cm mandibular exophytic growth, associated with loss of incisors teeth. On cut section, a hard, light-tan core was rimmed by a thick layer of soft tissue. Computed tomography examination confirmed the mandibular origin of the mass...

BACKGROUND: Osteoradionecrosis (ORN) of the jaws is among the most serious oral complications of head and neck cancer radiotherapy, arising from radiation-induced fibro-atrophic tissue injury, manifested by necrosis of osseous tissues and failure to heal, often secondary to operative interventions in the oral cavity. It is associated with considerable morbidity and has important quality of life ramifications. Since ORN is very difficult to treat effectively, preventive measures to limit the onset of this disease are needed; however, the effects of various preventive interventions has not been adequately quantified...

Ankylosis of the temporomandibular joint (TMJ) is a joint stiffness with an oral aperture of less than 30 mm measured between the incisors, occurring because of a bony, fibrous or fibro-osseous fusion. Arthrosis is a rare cause of the ankylosis of the temporomandibular joint. We report a case of ankylosis of the TMJ due to osteoarthrosis, in order to highlight the diagnostic and therapeutic features of this quite uncommon disease.

Mucoepidermoid carcinoma (MEC) can be rarely found as a primarily intraosseous lesion and mistaken for other intraosseous or odontogenic pathology. A 65-year-old man had a poorly defined radiolucency distal to the left mandibular second molar root. Periapical radiographs demonstrated a minor radiolucency from 2.5 years prior. An oral and maxillofacial surgeon felt the radiolucency represented periodontal disease, extracting tooth #18. The differential diagnosis of mixed radiolucent/radio-opaque mandibular lesions includes: (1) fibro-osseous lesion, (2) odontogenic and non-odontogenic cyst, (3) infection and inflammatory lesion, or (4) benign or malignant neoplasm (odontogenic, non-odontogenic, or metastatic)...

RATIONALE: Ossifying fibroma (OF) is a benign fibro-osseous lesion that can develop in the oral and maxillofacial region. OF is more common in females and has a marked predilection for the mandible, occurring rarely in the maxilla. Lesions grow slowly and are usually asymptomatic until growth produces an obvious swelling, pain, paresthesia, and facial deformity. With low rates of recurrence, treatment is usually curettage or resection. Very large lesions that invade other organs and that cannot be completely removed should be excised conservatively...

OBJECTIVE: Fibrous dysplasia (FD) is a benign bone disease characterized by fibro-osseous lesions. FD is caused by somatic mutations in the gene, guanine nucleotide-binding protein, alpha stimulating activity polypeptide 1 (GNAS), which encodes the G protein subunit, Gsα. FD manifests early in life, but the growth of lesions usually ceases in adulthood. FD lesions often exhibit somatic mutation mosaicism. In this study, the relationship between lesion growth and mutation prevalence within a lesion was investigated...

PURPOSE: The aims of this study were to describe the clinical and radiologic features of 383 fibro-osseous lesions (FOLs) from an oral pathology reference service in Brazil and to compare the findings with previous studies. The hypothesis of the study was that the most common type of FOL would differ from other investigations. MATERIALS AND METHODS: We conducted a descriptive and retrospective study with review of the records of the clinical and biopsy services (1990 to 2015)...

Maxillofacial imaging encompasses radiology of the teeth and jaws, including the temporomandibular joints. Modalities used include intra-oral radiographs, panoramic tomography, cephalograms, cone-beam computed tomography, computed tomography, magnetic resonance imaging, ultrasound, and radionuclide imaging. Common indications for imaging are impacted and supernumerary teeth, dental implants, inflammatory dental disease, and fibro-osseous lesions, cysts, and masses of the jaws. Osteonecrosis of the jaws may follow radiotherapy or the use of bisphosphonates and other drugs...

Florid cemento-osseous dysplasia (FCOD) is a rare, benign, multifocal fibro-osseous dysplastic process affecting tooth-bearing areas of the jaw, characterized by replacement of normal trabecular bone with osseous tissue and dense acellular cementum in a fibrous stroma. It is one clinicopathologic variant in a spectrum of related non-neoplastic fibro-osseous lesions known as cemento-osseous dysplasias (CODs), thought to arise from elements of the periodontal ligament. Diagnosis primarily relies upon radiographic and clinical findings; unnecessary biopsy should be avoided, as inoculation with oral pathogens may precipitate chronic infection in these hypovascular lesions...

INTRODUCTION: Florid osseous dysplasia is a rare and benign fibro-osseous pathology, in which bone is replaced by fibrous tissue and metaplastic bone. It can remain asymptomatic for a long time and is most often discovered incidentally during a radiological examination. Sometimes, patients are seen because of an infectious complication. OBSERVATION: An edentulous 62 years-old woman was referred for a painful mandibular swelling preventing insertion of her removable denture...

BACKGROUND: A preponderance of periapical radiolucencies are of inflammatory etiology (radicular cysts or periapical granulomas) secondary to pulpal disease. In some instances, however, a suspected periapical inflammatory lesion is not a consequence of pulpal disease but instead represents a lesion of noninflammatory origin. The differential diagnosis for such lesions is broad, ranging from odontogenic cysts and tumors to metastatic disease. As the biological behavior of such lesions is varied, the distinction between inflammatory odontogenic periapical lesions and lesions of noninflammatory origin in a periapical location is critical...

Florid cemento-osseous dysplasia (FCOD) belongs to the group of fibro-osseous lesions in which normal bone is replaced by fibrous connective tissue and calcified cementum tissue of the avascular type. Among the various types of fibro-osseous lesions, FCOD is one of the most commonly encountered diseases in clinical practice and may involve 3 or 4 of the quadrants. FCOD is located in the periapical regions of teeth, and the lesions are predominantly radiolucent (osteolytic phase), become mixed over time (cementoblast phase), and ultimately become radiopaque (osteogenic phase) with a thin radiolucent peripheral halo...

Fibrous dysplasia is a non-neoplastic hamartomatous developmental fibro-osseous lesion of bone. Monostotic fibrous dysplasia is more common than the polyostotic form and usually involves jaw bones, ribs and femur. Maxillary lesions may extend to involve the maxillary sinus, zygoma, sphenoid bone and floor of the orbit and require surgical intervention resulting in an acquired defect of the involved site. A multidisciplinary team approach involving an oral pathologist, oral surgeon, oral medicine expert and maxillofacial prosthodontist is required for successful treatment and rehabilitation of such patients...
