Abstract
OBJECTIVES To determine the role and efficacy of fine needle aspiration cytology (FNAC) and cell block in diagnosis of jaw lesions and compare the agreement between FNAC and cell block to predict the diagnosis. METHOD The sample comprised 51 cases, including 12 odontogenic keratocysts (OKCs), 8 ameloblastomas, 22 radicular cysts, 7 dentigerous cysts, and 1 each of intraosseous mucoepidermoid carcinoma (MEC) and adenomatoid odontogenic tumor (AOT). FNAC samples remaining after hematoxylin and eosin (H&E)-stained cytosmear diagnosis were centrifuged at 3,000 rpm for 10 min. The supernatant was discarded and sediment mixed with 2-3 mL alcohol and filtered. To this, 10% formalin was added, filtered, taken for routine processing, and stained with H&E. The result of FNAC smear and cell block was compared with histopathological diagnosis. RESULTS On cytological examination of the smears, 7 OKCs and 22 radicular cysts were diagnosed, whereas ameloblastomas, AOT, intraosseous MEC, and dentigerous cysts were not. This gave an agreement of 56.8% with the biopsy reports. Cell block sections stained with H&E of 12 OKCs, 22 radicular cysts, 1 MEC, and 3 cases of ameloblastoma offered a diagnosis in accordance with the biopsies giving an agreement of 74.5%, while dentigerous cyst and AOT failed to do so. In comparison with FNAC, additionally 5 cases of OKC and 1 of MEC could be detected, and in ameloblastoma, out of 8 cases, only 3 yielded a concordant diagnosis through the cell block technique. CONCLUSION In comparison with FNAC, the architectural pattern and the morphology of the cells were better preserved by the cell block technique. This substantiates that cell block could be used as an ancillary technique to aid in definitive diagnosis of head and neck swellings.

Abstract
RATIONALE Cutaneous perforators of peroneal vessels are divided into proximal and distal perforators on the basis of perforator distributions and musculocutaneous or septocutaneous properties. The traditional fibular osteocutaneous free flap is raised over the distal two-thirds of the fibula with a skin paddle based on distal perforators, which is affixed to the posterior crural septum. However, the skin pedicle may not be available due to anatomic variations or intraoperative injuries. Herein, because of the absence of distal perforators, we reserved and expropriated proximal perforators originating from the musculocutaneous branch of the superior part of the peroneal artery before it divided into nutrient and arcuate arteries and successfully harvested a separate osteal fibula and proximal perforator skin paddle with a single vascular pedicle-peroneal vessel. PATIENT CONCERNS A 62-year-old man with a 6-month history of mandibular swelling and soft tissue invasion was referred to us. DIAGNOSIS Panoramic radiography and computed tomography showed an irregular radiolucent lesion of the mandibular body, and histopathological analysis confirmed a follicular-pattern ameloblastoma. INTERVENTIONS The diseased mandible and soft tissue were resected and reconstructed with a vascularized fibular osteal flap with the proximal perforator skin paddle. OUTCOMES The mandibular contour was successfully restored; the skin paddle in the mouth was in good condition after 8 months of follow-up. LESSONS The proximal perforator is reliable and practical for supplying a skin paddle and has significant potential for future applications. We recommend reserving the proximal perforator skin paddle as a backup flap when planning to raise a fibula flap, since unavailability or injury of the traditional fibular skin island based on distal perforators occurs frequently. This approach can avoid the exploration for a second donor site, save surgical time, and reduce surgical complexity. Moreover, we anticipate more frequent use of the proximal perforator flap in the future because of its flexibility and large volume, and since it can be combined with the osteal fibula or fibular osteocutaneous flap. However, an understanding of the traits of the proximal perforator and determination of its peroneal origin by computed tomography angiography is crucial for predesigning fibular osteal flaps with a proximal perforator skin paddle.

Abstract
Malignancy of melanocytes, a pigment-producing cell, is referred as malignant melanoma (MM) which occur basically on skin and oral mucous membrane, but as well found in ears, eyes, gastrointestinal tract and genital mucosa. Oral melanomas has propensity to metastasise and invade more voluntarily than other malignant counterparts. Here we present a case of 52-year-old male patient with a chief symptom of blackening of gums in the upper front tooth region. In dental history, the patient revealed history of faulty artificial prosthesis fixed in the same region since 6 months. On the basis of a through clinical assessment, a provisional opinion of oral malignant melanoma, was prepared. On histopathological and immunohistochemical analysis with S-100 and homatropine methylbromide 45 the diagnosis of MM was confirmed.

Abstract
While primary hyperparathyroidism (PHPT) generally represents a common endocrine disorder, being the more frequent cause of hypercalcemia in outpatients, familial forms of PHPT (FPHPT) account for no more than 2-5% of the overall PHPT. In the last decades, many technical progresses in both molecular and biochemical-radiological evaluation have been made, and substantial advancements in understanding these disorders have been reached. Differences both in the pathogenesis and clinical presentation exist among the various hyperparathyroid syndromic forms, and, since FPHPT is frequently associated to other endocrine, proliferative and/or functional disorders, as also non-endocrine tumours, with varying clinical spectrum of occurrence in each syndrome, its early clinically detection for appropriately preventing complications (i.e. kidney and bone disorders) is strictly advised. In this review, the clinical-biochemical features and diagnostic procedures of each FPHPT form will be summarized and a general overview on surgical and pharmacological approaches to FPHPT has been also considered.

Abstract
The purpose of this study was to integrate the available published data on melanotic neuroectodermal tumour of infancy (MNTI) of the jaws into a comprehensive analysis of its clinical/radiological features, with emphasis on the predictive factors associated with recurrence. Eligibility criteria included publications with sufficient clinical/radiological/histological information to confirm the diagnosis. A total of 288 publications reporting 429 MNTI cases were included. MNTIs were slightly more prevalent in males and markedly more prevalent in the maxilla. Most of the lesions were asymptomatic, presenting cortical bone perforation and tooth displacement. Nine lesions were malignant, with metastasis in five cases. Enucleation was the predominant treatment (67.2%), followed by marginal (18.4%) and segmental resection (6.1%). Eighty-one of 356 lesions (22.8%) recurred. Recurrence rates were 61.5% for curettage, 25.3% for enucleation alone, 16.2% for enucleation+curettage, 20.0% for enucleation+peripheral osteotomy, 11.3% for marginal resection, 10.0% for segmental resection, 30.0% for chemotherapy, and 33.3% for radiotherapy. Enucleation and resection presented significantly lower recurrence rates in comparison to curettage. Curettage appears not to be the best form of treatment, due to its high recurrence rate. As resection (either marginal or segmental) is associated with higher morbidity, enucleation with or without complementary treatment (curettage or peripheral osteotomy) would appear to be the most indicated therapy.

Abstract
The aim of this case series was to reveal the difficulties in diagnosing fibro-osseous lesions with radiological and histopathological examinations and quantify the potential risk of infection to fibro-osseous legions. To analyze the concordance between radiological and histopathological diagnoses, this retrospective case series included patients who were clinically diagnosed with fibro-osseous lesions via radiological findings and excluded the patients who did not undergo histopathological examinations. This study also included the patients in whom histopathological results confirmed fibro-osseous legions when preoperative radiological diagnosis did not include fibro-osseous legions. Eleven patients (three men, eight women; median age 24.5 years, range 15-57 years) were enrolled. Although radiological diagnoses of fibrous dysplasia (FD) corresponded with histopathological diagnoses in seven patients, mismatches between radiological findings and histopathological results were found in three patients. In one patient, suspected diagnosis with radiological examinations was malignant lymphoma or FD. In two patients, the histopathological differentiation between FD and ossifying fibroma (OF) was difficult. One patient had lesion recurrence which was suspected to be OF with surgical findings and postoperative course after the initial surgery. In three patients, infections of FD were found. Preoperative diagnosis of OF with radiographic feature of unilocular radiolucency is difficult. In cases in which histopathological differentiation between FD and OF is difficult, operative findings should be used because OF is often found to be well-encapsulated and easily enucleated. Bone in FD showing mixed radiolucent-radiopaque may be vulnerable to infection.

Abstract
RATIONALE Familial gigantiform cementoma (FGC) is a rare benign autosomal dominant fibrocemento-osseous lesion generally limited to the facial bones, typically in the anterior portion of the mandible; it is often associated with abnormalities of the long bones and prepubertal pathologic fractures. Owing to the small number of such patients, a uniform treatment criterion has not been established. This paper presents a patient with FGC who was treated in our department, and offers a systematic review of the patients reported in the literature. Our aim was to explore the treatment strategy for patients with FGC. PATIENT CONCERNS Our patient, a 13-year-old boy, presented with a painless enlargement of the mandible first noted 2 years earlier. It had grown rapidly over the preceding 8 months, affecting both his appearance and ability to chew. DIAGNOSIS Based on the pathologic, clinical, and radiographic features, FGC was diagnosed. INTERVENTIONS Mandibuloectomy was performed. The mandibular defect was immediately reconstructed with his right vascularized iliac crest flap. At the same time, a PubMed search was conducted to identify studies reporting on other patients with FGC. OUTCOMES A 3-dimensional computed tomography (3D-CT) scan demonstrated appropriate height of the new alveolar bone. Follow-up results showed recovery of the patient's appearance and mandibular function. He was free of recurrence at 4-year follow-up. LESSONS FGC is a rare benign fibrocemento-osseous lesion of the jaws that can cause severe facial deformity. Incomplete removal leads to more rapid growth of the residual lesion. Therefore, extensive resection is a suitable strategy to avoid recurrence. Defects of the facial bones found intraoperatively should be repaired with resort to an appropriate donor site. However, it is important to be aware that patients with FGC always have concomitant abnormalities of skeletal metabolism and structure, as well as a vulnerability to fractures of the long bones of the lower extremity. Therefore, the optimal management strategy should include a review of treatment options for other patients as reported in the literature. An optimal protocol can not only provide sufficient high-quality bone suitable for the reconstruction of bone defects, but also minimize complications and maximize quality of life.

Abstract
The jaws combine several unique properties that mainly result from their distinct embryonic development and their role in providing anchorage for the teeth and their supporting structures. As a consequence, several bone-related lesions almost exclusively develop in the jaws (eg, osseous dysplasias, ossifying fibromas), have distinct clinical features (eg, osteosarcoma), or hardly ever occur at this location (eg, osteochondroma, enchondroma). The specific characteristics of these tumors and tumorlike lesions are outlined in this article.

Abstract
Multiple odontogenic keratocysts could be linked to different conditions. Then, to achieve the correct diagnosis whether their presence is associated to a syndrome, some criteria must be followed. The present study aims to report a case of a 21 years-old male patient whose was referred with several radiolucent lesion on the maxilla-mandibular complex. The lesions were biopsied and the diagnosis of the histological exam hypothesized as odontogenic keratocyst. After complete evaluation, others abnormalities were also found such as calcification of falx cerebri, palmar and plantar pits, and multiple basal cell on feet. The patient was diagnosed with Gorlin-Goltz syndrome and was referred to other medical specialties to adequate follow-up. Dental surgeon represents an important role on correct diagnosis of the Gorlin-Goltz syndrome and could avoid further complications.

Abstract
Hypoxia-inducible factor-1α (HIF-1α) promotes proteins that enable cell survival during hypoxia, such as glucose transporter 1 (GLUT-1). Their coexpression has been associated with aggressiveness in malignancies and has not been studied in odontogenic tumors. Immunohistochemical expression of HIF-1α and GLUT-1 was analyzed in 13 tooth germs (TGs), 55 ameloblastomas (AMs), and 3 ameloblastic carcinomas (ACs). HIF-1α was negative in all TGs, and just 1 case of AM and 1 of AC had nuclear positivity. GLUT-1 expressed in ameloblastic cells of all TGs, AMs, and ACs, with an increasing intensity, respectively, and was significantly higher in solid AM than in unicystic AM (P = .041). Absence of nuclear HIF-1α in TGs and most AMs suggest that GLUT-1 may be induced by alternative pathways to hypoxia. However, in ACs, HIF-1α may be activated; however, to confirm this, additional cases are needed. GLUT-1 overexpression could be related to aggressiveness in AMs and ACs and must represent a normal metabolite in TGs.

Abstract
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. METHODS A retrospective study of 5,993 archival periapical biopsies over a span of 15 years from the database of the Oral Pathology Biopsy Service in the Henry M. Goldman School of Dental Medicine at Boston University recorded the incidence of various lesions in a periapical location. RESULTS Of the cases studied, 97.2% represented lesions of inflammatory origin with histopathologic diagnoses as follows: periapical granuloma (60.0%), radicular cyst (36.7%), periapical fibrous scar (0.27 %), and periapical abscess (0.23 %). The remaining 2.8% cases were lesions of noninflammatory origin with histopathologic diagnoses of odontogenic keratocyst (also known as keratocystic odontogenic tumor), benign fibro-osseous lesions, and ameloblastoma. One patient had Langerhans cell disease, and 1 had central giant cell granuloma. CONCLUSIONS Although most periapical specimens biopsied represented expected inflammatory periapical lesions, the biological behavior of underdiagnosed lesions may have considerable consequences for both the patient and the clinician. PRACTICAL IMPLICATIONS This article serves to inform clinicians regarding the diversity of lesions arising in the periapical region of the jaws, to assist in the formulation of differential diagnoses, and to highlight the importance of submission of lesional tissue for histopathologic evaluation and definitive diagnosis when biopsy is clinically indicated.

Abstract
Familial gigantiform cementoma is an exceedingly rare but distinct subtype of cemento-osseous-fibrous lesion. Undocumented radiographic changes and related bone metabolism disorder are herein hypothesized and discussed. We present an adolescent case with recurrent familial gigantiform cementoma who received surgical intervention in our hospital. Apart from typical multiquadrant and expansile abnormalies involving both jaws, he also suffered from several times of fractures in lower extremity. Furthermore, radiographic examinations of calvaria, pelvis, femoris, tibia, and fibula all revealed radiolucent areas signifying diffuse osteopenic bone losses. Some of his consanguineous relatives bore the same burden of fractures during pubertal period.Considering these polyostotic conditions, a correlation of congenital bone metabolism disorder in cases with familial gigantiform cementoma, named "calcium steal disorder," was thus proposed. Familial gigantiform cementoma is closely associated with "calcium steal disorder." Whole-body dual-energy absorptiometry should be considered as a routine examination for fracture-related risk prediction.

Abstract
PURPOSE Primary Ewing sarcoma of the jaw is rare. The aim of this study was to describe new cases of primary Ewing sarcoma of the jaw and investigate reported prognostic factors of Ewing sarcoma in this series and treatment outcome. MATERIALS AND METHODS Six patients with primary Ewing sarcoma of the jaw were treated at the Memorial Sloan Kettering Cancer Center (MSKCC) from 1992 through 2013. Clinical data, pathology reports, treatment prescribed, treatment regimens, outcome, and follow-up information were reviewed. RESULTS Five of 6 patients were female and 5 cases were in the mandible. No patient presented with metastatic disease at diagnosis. All cases were positive for CD99, and 3 patients with genetic confirmation were positive for EWS-FLI1 fusion or EWSR1 gene rearrangement. All patients received induction multiagent chemotherapy and surgical resection and 2 patients received adjuvant radiotherapy. Total (grade IV) or nearly total (grade III) tumor necrosis in 3 of 5 patients (60%) assessed for histologic response to chemotherapy indicated intense sensitivity. All patients were alive and free of disease, with no history of local recurrence, at a median follow-up period of 6.5 years. CONCLUSION Patients with primary Ewing sarcoma of the jaw have a good prognosis and metastasis is an uncommon occurrence at initial presentation.

Abstract
Although benign, ameloblastomas are locally invasive and destructive tumors of the jawbones. The glypicans comprise a family of glycosylphosphatidylinositol-anchored proteoglycans that, by virtue of their cell-surface localization and heparin sulfate chain composition, might regulate the response of cells to numerous heparin-binding growth factors, cell adhesion molecules, and extracellular matrix components. The expression of glypican-1 is differentially altered among different types of malignancies, suggesting a possible role in the tumorigenesis and biological behavior of these neoplasms. The aim of this study was to determine the expression of glypican-1 and then hypothesize the possible role that this protein may play in the biological behavior of ameloblastomas. We assessed the presence of glypican-1 by immunohistochemical staining analyses in a series of 80 cases of different types of ameloblastomas. Desmoplastic ameloblastomas exhibited the highest expression of glypican-1 (100%), followed by the peripheral (66%), solid/multicystic (51.2%), and unicystic (47.2%) types, showing statistically significant differences among them (P<0.001). Differences detected in glypican-1 expression among different subtypes of ameloblastomas, could be suggesting a possible association with their different biological behavior.

Abstract
Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a well-characterized oral complication of systemic therapy with bisphosphonates. Pseudoepitheliomatous hyperplasia was observed in some of the lesions. Because podoplanin expression has been linked to malignant lesions of the oral mucosa, we aimed to investigate podoplanin expression in the pseudoepitheliomatous hyperplasia. We analyzed archival paraffin- and plastic-embedded specimens from BRONJ using both conventional and immunohistochemical (AE1/AE3, D2-40) staining methods. Eleven out of seventeen BRONJ cases showed pseudoepitheliomatous hyperplasia. All these cases were positive for AE1/AE3 and pseudoepitheliomatous hyperplasia displayed a strong basal and parabasal reaction against podoplanin. The podoplanin expression in pseudoepitheliomatous hyperplasia in BRONJ specimens should not be considered a sign of malignancy. We discuss the current and possible future roles of surgical pathologists in diagnosing morphological changes associated with the development and therapy of BRONJ lesions.

Abstract
Central giant cell granuloma (CGCG) is a benign, non-odontogenic bone lesion of jaw. The condition is relatively infrequent and affects mainly children and young adults with a certain predominance among females and exhibits variable aggressiveness. Giant cell lesion associated with hyperparathyroidism is known as Brown tumor. Brown tumor is one of the bony complications of hyperparathyroidism. It is a giant cell granuloma which occurs in osteitis fibrosis cystica. It represents the terminal stage of the bone remodelling processes occurring as a result of peritrabecular fibrosis and osteoclastic activity. The mandible is the predominantly affected site in the maxillofacial area. Maxillary involvement is rare. The incidence of Brown tumor associated with hyperparathyroidism is rare (0.1%). Here, an extremely rare case of a 20 year old female patient with Brown tumor in her maxilla and mandible associated with primary hyperparathyroidism was presented. A thorough diagnostic work up showed presence of tumor mass in mandible and maxilla and elevated serum alkaline phosphatase and parathormone level and the patient was treated for both hyperparathyroidism and Brown tumor were discussed. The importance of different radiological evaluation methods and the consultation between the oral and maxillofacial surgeons, dentists, endocrinologists and radiologists were emphasized.

Abstract
Cytology features of childhood jaw tumors are infrequently reported in the literature. Fine-needle aspiration cytology (FNAC) has been used with good results in the differential diagnosis of bone lesions, being an excellent tool for the diagnosis of metastases and in the frontline approach to primary lesions. We report 3 cases of young children aged 3 years (case 1), 5 months (case 2), and 15 years (case 3) with jaw tumors diagnosed by FNAC. In the first two cases the diagnosis was prognoma, and in the third case cementifying fibroma. Despite the clinical and imaging similarity of the 3 cases - large maxillary/mandibular tumors - their characteristic cytological features allowed a confident diagnosis, excluding other differential alternatives. In both case 1 and case 2 a dual cell population of neuroepithelial and melanocytic cells was identified, consistent with a melanotic neuroectodermal tumor. In case 3 the presence of a bland spindle cell population as well as of several nodular dense eosinophilic, osteoid-like (cement) matrices, indicated a cementifying fibroma. All cases were resected and confirmed by histological examination. A review of the literature, including differential diagnosis, addresses the utility of FNAC in childhood jaw tumors.

Abstract
Almost all variants of malignant primary and secondary tumours of bone have been described as occurring within the jaws. Odontogenic carcinomas and sarcomas are peculiar to the jawbones and are distinctly uncommon. Non-odontogenic tumours in comparison arise with more frequency, yet the maxilla and mandible remain unusual sites for most primary and secondary non-odontogenic tumours of bone. The most commonly occurring primary bone tumours affecting the jaws include osteosarcoma, Burkitt's lymphoma and multiple myeloma, while secondary or metastatic tumours to the jaws are rare in contrast to the remainder of the skeleton.

Abstract
The odontoameloblastoma (OA), also known as ameloblastic odontoma, is a rare neoplasm of jaws which includes odontogenic ectomesenchyme in addition to odontogenic epithelium that resembles an ameloblastoma both in structure and in behaviour. The exact incidence is difficult to determine. Since 1944, only 24 cases have been reported in English literature which fulfill both histological and clinical features of this lesion. The Authors report a case report of an odontoameloblastoma in a 15-year-old caucasian man treated with a surgical excision. The five years follow-up shows no evidence of recurrence confirming the validity of a conservative surgery with enucleation of OA, followed by periodical clinical and radiographical controls.

Abstract
A variety of pain disorders involve the head, neck, jaws, and face. Many contradicting symptoms may exist when a patient presents with multiple problems. In order to diagnose and treat dental disease, a thorough understanding of both odontogenic and nonodontogenic etiologies of toothache pain is paramount. Harvey McGehee, a noteworthy medical diagnostician, wrote: "In making the diagnosis of the cause of illness in an individual case, calculations of probability have no meaning. The pertinent question is whether the disease is present or not. Whether it is rare or common does not change the odds in a single patient. If the diagnosis can be made on the basis of specific criteria, then these criteria are either fulfilled or not fulfilled." Good diagnosticians in all fields of medicine are on the endangered species list. To become a successful diagnostician, one needs to have interest, intuition, curiosity, patience, and a quest for knowledge. Each day presents a new opportunity and you can either be the goat, or the GOAT (greatest of all time). The choice is yours.

Abstract
OBJECTIVE Intraosseous mucoepidermoid carcinoma of jaws is rare, and management of the disease remains poorly understood. The aim of this study was to assist the diagnosis and treatment of the tumor. STUDY DESIGN The records of clinical data and follow-up information were collected from 1996 to 2010 and retrospectively analyzed for clinical features, surgical intervention, and prognosis. RESULTS Of 24 cases, 15 were male, and the average age was 47.33 years. The clinical presentation of this tumor varied. For primary lesions and neck nodes, radical surgery was performed; radiotherapy or chemotherapy was administered after operation. The survival rate of all patients was 66.7%. The average survival period was 53.3 months after surgery. CONCLUSIONS Diagnosis should be based on clinical and pathologic manifestations, surgery is the first choice for patient treatment, and radiotherapy may improve prognosis and therefore should be recommended in postoperative period.

Abstract
Osteosarcoma of the jaw is a rare disease; we report two cases, one in which the primary osteosarcoma had occurred in the sacrum and ileum, the second at the mandible. Dissemination of osteosarcoma to other organs, especially early dissemination to the lung, is common, but metastasis to the jaw has only rarely been reported. About 10% of osteosarcomas occur in the head and neck, most in the mandible or maxilla. Clinically, both patients presented swelling, and pain at the jaw in the premolar-molar region. At radiography, extensive bone erosion and soft-tissue swelling were apparent. A biopsy was taken and a diagnosis of osteosarcoma rendered in both cases. Histological examination revealed a proliferation of atypical osteoblast-like cells with hyperchromatic nuclei and formation of scattered neoplastic osteoid tissue. Immunohistochemistry for a panel of antibodies showed strong positivity for CD99, weak positivity for S-100, but was negative for desmin, vimentin, and cytokeratins. The diagnosis for both cases was of osteogenic osteosarcoma, chondroblastic subtype. Unfortunately, both patients died, one before the planned chemotherapy regime could begin, the second during the chemotherapy course. Our report aims to highlight the importance of the diagnostic profile in formulating a diagnosis of osteosarcoma, and that this tumor, although very rare, may be primary or may metastasize to the jaws.

Abstract
Osteochondromas are the most common benign bone tumor, most commonly found in the ends of long bones; however, they rarely involve facial bones, particularly the mandible. Osteochondromas involving the coronoid process have rarely been reported in the literature but pose a diagnostic dilemma. When large enough, osteochondromas of the mandibular coronoid process can form a joint with the zygomatic arch (Jacob's disease). This pseudoarticulation results in restricted jaw motion, which can clinically be mistaken for temporomandibular joint dysfunction. We report a case of a 39-year-old man with chronic restricted jaw motion undiagnosed for several years.

Abstract
OBJECTIVES To explore the demographic characteristics and clinical features among patients with osseous (cemento-osseous) dysplasia (OD/COD) of the jaws and to determine the frequency of particular radiographic characteristics. METHODS The charts and radiographic reports of 118 patients with OD/COD, obtained from the archives of the University of Toronto discipline of oral and maxillofacial radiology, were reviewed. Demographic and clinical data, radiographic findings and final diagnoses were collected and analyzed to determine typical characteristics. RESULTS Of the 117 patients for whom age and sex were known, the majority (97 [82.9%]) were female; these female patients had a mean age (± standard deviation) of 44.3 ± 13.4 years. Eighty-three (72.2%) of the 115 patients for whom symptoms were known were clinically asymptomatic. Ninety-three patients (78.8%) had OD/COD at single sites (i.e., periapical OD/COD), and 25 (21.2%) had OD/COD at multiple sites (i.e., florid OD/COD). In addition, 15 (12.7%) of the cases were associated with one or more simple bone cysts, and 13 (11.0%) were associated with osteomyelitis. In most cases, the OD/COD was unilateral, with the lesion being located in the mandible, usually associated only with the posterior teeth. The lesions exhibited well-defined, sclerotic or corticated margins (108 patients [91.5%]) and were surrounded by a radiolucent border. Minimal effects on surrounding structures were observed. As well, 85 (72.0%) of the lesions were in the mixed radiolucent-radiopaque stage, with dense, cementum-like radiopacities. CONCLUSIONS The majority of cases of OD/COD occurred in women in the fifth decade of life, and most cases were asymptomatic. OD/COD was more likely to present as solitary lesions but also occurred in association with simple bone cysts or osteomyelitis.

Abstract
Magnetic resonance imaging (MRI) is a radiological imaging method that has not yet found routine application in the detection and assessment of malignant tumors of the maxillofacial region. The aim of this study was to evaluate MRI in the detection, diagnosis and differential diagnosis of malignant tumors of the maxillofacial region. This prospective study included 42 patients with clinically confirmed malignant tumors of the maxillofacial region. All patients were examined by MRI. This imaging method was evaluated for the ability to detect tumor location and to analyze dimensions and structure of the tumor, bone involvement, effect on neurovascular structures and extension to soft tissues. MRI results were compared with histopathologic and intraoperative findings as the 'gold standard' methods. MRI identified all of the clinically confirmed tumors. The sensitivity for tumor location was 94.4%, tumor necrosis 93%, hemorrhage 93.3% and bone involvement 91.4%. The specificity for tumor location was 84%, tumor necrosis 92.8%, hemorrhage 92.8% and bone involvement 85.7%. In the evaluation of soft tissue tumor extension to bone structures, MRI sensitivity and specificity was 94.4% and 88.2%, respectively. The sensitivity for perineural infiltration and tumor involvement of vascular structures was 91% and 91.6%, respectively. The specificity for perineural infiltration was 96.7% and for tumor involvement of vascular structures 88%. MRI sensitivity and specificity for intracranial extension, intraorbital propagation, extension to pterygopalatine fossa and other surrounding anatomic spaces was 93.5% and 90.9%, respectively. MRI proved advantageous for the ability to distinguish neurovascular structures from adjacent soft tissues without the use of intravenous contrast media. Study results demonstrated MRI to provide valuable information in the analysis of tumor structure, bone involvement and extension to soft tissues of malignant tumors of the maxillofacial region.

Abstract
Calcifying odontogenic cyst is a rare lesion representing about 1% of jaw cysts. It may occur in a central (intraosseous) or peripheral (extraosseous) location. A case of peripheral calcifying odontogenic cyst located on the gingiva, appearing as a painless, circumscribed, sessile, and pink to red nodule has been reported.Peripheral, in contrast to central, calcifying odontogenic cyst tends to affect older patients. Peripheral calcifying odontogenic cyst is a less aggressive lesion than the central counterpart, and a simple excision biopsy is curative. The histologic findings of an epithelium rich in ghost cells has helped in making the diagnosis.

Abstract
INTRODUCTION Although metastatic jaw lesions are rare, clinicians must be aware of occurrence and should include them in their catalogue of differential diagnoses with a view to requesting for useful investigations that will aid timely consult and available palliative interventions. The aim of this study is to review and analyze the epidemiological behaviour of jaw metastases that have been reported in literature. METHOD The review was conducted at the Oral and Maxillofacial Department of the University of Port Harcourt Teaching Hospital. Information was obtained from articles written by various authors in Nigeria and other parts of the world and from the internet services provided by the Information and computer training centre of the University of Port Harcourt. A total of 31 articles were reviewed. The distribution, clinical manifestation at the secondary sites, investigations and treatment of the metastatic jaw diseases from the various primary sites were reviewed and documented. RESULT A total of 890 cases were reviewed, males were 402 and females were 488. The age range was 13 to 75 years with a mean age 43 years. The mandible was involved more than the maxilla. In 30% of cases, there were no symptoms at the secondary sites, lesion were detected by radiographs and scintiscanning. Other patients presented with jaw/facial swelling and pain. The breast was the commonest primary site in females and the lung in males. Histopathology was used to confirm the metastatic lesions and 61% of them were found to be adenocarcinoma. Less than half of the cases were operable, and surgery of primary and secondary sites was combined with radiotherapy and chemotherapy in these cases. Prognosis was poor with varying survival rates. CONCLUSION Despite the fact that metastases to the jaws are rare than other bones of the body, these may be the first indication of a malignancy elsewhere in the body and this necessitates that suspected jaw swelling should be thoroughly evaluated to expedite treatment.

Abstract
Considerable variation in the clinicopathologic presentation of epithelial odontogenic tumors can sometimes be confusing and increase the chance of misdiagnosis. Seven diagnostically challenging jawbone lesions are described. There were 2 cases of mistaken identity in our ameloblastoma file. One unicystic type, initially diagnosed and treated as a lateral periodontal cyst, showed destructive recurrence 6 years postoperatively. The other globulomaxillary lesion was managed under the erroneous diagnosis of adenomatoid odontogenic tumor and recurred 4 times over an 11-year period. This tumor was found in retrospect to be consistent with an adenoid ameloblastoma with dentinoid. The diagnosis of cystic squamous odontogenic tumor (SOT) occurring as a radicular lesion of an impacted lower third molar was one of exclusion. Of two unsuspected keratocystic odontogenic tumors, one depicted deceptive features of pericoronitis, while the other case has long been in our files with the diagnosis of globulomaxillary SOT. Two cases of primary intraosseous squamous cell carcinoma appeared benign clinically and exhibited unexpected findings; an impacted third molar began to erupt in association with the growth of carcinoma and another periradicular carcinoma showed dentinoid formation. Cases selectively reviewed in this article present challenging problems which require clinical and radiographic correlation to avoid potential diagnostic pitfalls.

Abstract
One month post extraction of the second left maxillary molar the alveolar extraction site showed no signs of healing and was painful. The patient had been using an oral bisphosphonate during 3 years. Therefore, the lesion was diagnosed as bisphosphonate-induced maxillary osteonecrosis. Treatment was conservative. Since one month later the pain had increased and the wound healing had decreased, a biopsy was carried out. Histopathologic examination revealed a non-Hodgkin lymphoma.

Abstract
Gardner syndrome (GS) is an abnormality of familial adenomatous polyposis accompanied by characteristic jaw lesions. Gardner syndrome intestinal polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and surgical intervention of the disease are important to prolong the life of the patient. We present a case of GS in a 55-year-old woman. Familial adenomatous polyposis, osteomatous jaw and ocular lesions, several dental abnormalities, and an abdominal desmoid tumor are the characteristic features of this case. This case demonstrates the presence of unusual, widespread, hereditary, osteomatous jaw lesions that caused diagnostic confusion with familial gigantiform cementoma.

Abstract
OBJECTIVE To evaluate the epidemiological and clinical aspects of the different types of odontomas. STUDY DESIGN A metaanalysis was made of 3065 odontomas obtained from a literature review of 30 articles published in recent years. RESULTS Odontomas show no gender predilection, and are most often diagnosed in the second decade of life. They are preferentially located in the upper maxilla, particularly in the anterior sector. Compound odontomas are more prevalent than complex odontoma, and show no predilection in terms of patient gender, age or location. Most such lesions are asymptomatic and constitute casual findings in X-ray studies indicated for other reasons. The most common clinical manifestations are the retention of permanent teeth and the presence of a tumor. Treatment consists of surgical removal of the lesion. The prognosis is very good, with a scant tendency towards relapse. CONCLUSIONS Odontomas are the most common odontogenic tumors. Their most significant characteristics comprise alterations in tooth eruption, and the diagnosis is casually established in the course of routine X-ray studies.

Abstract
OBJECTIVE To assess the value of multi-slice spiral CT (MSCT) with three dimensional (3D) reconstruction in the diagnosis of neoplastic lesions in the jawbones. METHODS Thirty-three patients with neoplastic lesions of the jawbones underwent MSCT scanning with 3D reconstruction. Of these patients, 14 had ameloblastoma, 8 had hemangioma, 3 had osteosarcoma, 3 had ossifying fibroma, 2 had chondrosarcoma, 2 had fibrosarcoma, and 1 had odontogenic myxoma. Preoperative MSCT scanning was performed with the slice thickness of 2 mm, and 3D reconstruction of the images was conducted by means of multi-planar reconstruction (MPR), curved-planar reformation (CRP), and 3D volume rendering technique (VRT). The results were compared with those observed during the operations. RESULTS In the 33 cases, the neoplastic lesions of the jawbones were displayed by 2D or 3D imaging and confirmed by intraoperative findings. Two-dimensional imaging allowed better observation than 3D imaging of the deep structures, whereas 3D imaging was superior in visualizing the morphological changes of the compromised bones and the spatial relationship between the tumors and surrounding structures. Two-dimensional imaging and MPR were excellent in revealing the internal structures and pathological changes of tumors, having also better performance in showing the tumors involving the soft tissues. Benign tumors were most visualized as bone expansion changes with well defined ovoid or lobulated borderlines, and malignant ones often resulted in adjacent bony destruction and soft tissue masses. CONCLUSION MSCT examination is useful in defining the scope of tumor involvement and bony changes to help in the definite diagnosis, differential diagnosis and choice of clinical treatment. Two-dimensional imaging, MPR, VRT and CRP have their respective advantages and limitations in showing jawbone tumor, and their combination can be of great clinical value.

Abstract
Desmoplastic ameloblastoma is a benign, locally aggressive neoplasm of proliferating odontogenic epithelial origin. It is seen among old patients from 17 to 72 years with an average age 42 years and without predilection of sex. We report the case of a 7 year old child, having presented since the 5 years age, a gingival tumefaction on the left higher incisivo-canin group which increased volume gradually. The stomatologic examination showed a gingival tumefaction covered with a healthy mucous membrane, ovoid form and measuring 3 cm on its horizontal axis. The tomodensitometry of the jawbone showed in front of the 21st and the 22nd tooth, the presence of an osseous lesion associating of the hearths of osteolysis and osteocondensation with rupture of cortical and invasion of the soft tissue. A curetting of the lesion was carried out and the anatomopathologic examination retained the diagnosis of desmoplastic ameloblastoma. The characteristic of our observation is the youth of the patient. In addition, the desmoplastic ameloblastoma is relatively rare, is characterized by an anatomical distribution, a radiological appearance and a morphological aspect differents from the traditional ameloblastoma. A radical surgical treatment is suggested for this tumour to avoid recurrency.

Abstract
BACKGROUND With the new term "keratocystic odontogenic tumour" (KCOT) keratocyts are even in the nomenclature a close differential diagnosis to ameloblastomas (A). PURPOSE Recurrence of KCOT and A were retrospectively compared with regard to treatment and immunohistochemical markers of cell cycle and migration and cell architecture. PATIENTS AND METHODS Biopsies harvested over a period of 22 years of 101 patients (86 KCOT, 15 A) were examined. The histopathological slides were stained with H&E and with the immunohistochemical markers: Cyclin D1, Collagen IV, p16, Cox-2-Laminin-5 and Tenascin-C. RESULTS Mean age KCOT 47 years (range 14-80 years), A 41 years (range 16-79 years). Gender KCOT: m:f =2:1; A: m:f = 3:2. Region of origin mandible with predilection of the angle and the ramus: KCOT: 76; A: 12. Maxilla: KCOT: 18; A: 3. Multiple lesions were found in 5 KCOT patients. Treatment primary KCOT: cystectomy (46), cystostomy (6), cystectomy and curettage (17), cystectomy and marginal ostectomy (14), resection (11). A: resection (10), enucleation (5). Recurrence rate KCOT: 11,7% after 5,5 years. Recurrence after: cystostomy (4), cystectomy (6), cystectomy and curettage (3), cystectomy and marginal ostectomy (2). A: no recurrences. Immunohistochemistry Cell cycle associated and extracellular matrix proteins did not differ in quantity in KCOT and A, and did also not differ in recurrent and non-recurrent KCOT. CONCLUSIONS 1. KCOT are in the own cohort more likely recurrent than A. 2. Recurrence rate of KCOT can not be predicted by the used (most common) markers of cell cycle, migration and modulation of architecture. 3. Higher recurrence rate of KCOT in the patients examined is proposed due to less extensive resection.

Abstract
PURPOSE The aim of the present study was to assess the quality of life (QoL) in 103 patients with oral cavity and jaw cancer, using an original rating scale. PATIENTS AND METHODS In order to assess the QoL in such patients an original rating scale was developed and validated. For statistics alternative analysis, non parametric tests, correlation analysis, and graphic analysis were used. RESULTS Most patients were rated as grade III or IV according to the 5-grade scale (grade IV the most severe). Their QoL was significantly deteriorated, resulting in depression and despair. Reconstruction and prosthesis implantation and social rehabilitation were needed in these patients. QoL was assessed in 19 patients prior to and following prosthesis implantation. Prior to implantation most patients were rated as grade III or IV, whereas the majority of them were rated as grade 0 or 1 following prosthesis implantation. Prosthesis implantation contributed to improvement of speaking and feeding and elimination of disfigurement. CONCLUSION After assessment of QoL, patients rated as grade III or IV should have access to complex medical management, including prosthesis implantation and social rehabilitation.

Abstract
Fibrosarcoma (FS) is a malignant mesenchymal neoplasm of the fibroblasts that rarely affects the oral cavity. Two cases of primary FS of the jaws with intraosseous growth (2 men, aged 53 and 71 years) are described. Microscopically, in one case the tumor showed an intense proliferation of spindle-shaped cells, varying little in size and shape and arranged in parallel bands, partly crossing each other, with significant mitotic activity and nuclear pleomorphism; the second case was characterized by low cellularity comprising spindle-shaped cells, deposited in a variably fibrous and myxoid stroma. On immunohistochemistry, cells in both cases were strongly immunoreactive for MIB-1 and vimentin, focally positive for CD68, and negative for S-100 protein, pancytokeratin, HMB45, CD34, desmin, smooth muscle actin (SMA) and epithelial membrane antigen (EMA). Based on clinical, histological and immunohistochemical findings, the final diagnosis was FS in the first case, myxofibrosarcoma in the second. Treatment was radical surgery with mandibular reconstruction. After two years, the first patient displayed multiple metastases and died during the third year after the initial diagnosis; the second patient was still alive and doing well five years after treatment. We discuss the differential diagnosis versus other forms of sarcoma, examining the morphological appearance that is frequently very similar, the immunohistochemical expression of MIB-1, vimentin, S-100, CD-34, CD68, EMA, as well as conventional clinicopathological features that may help to distinguish FS from other sarcomas.

Abstract
Recently, jawbone osteonecrosis has been largely reported as a potential adverse effect of bisphosphonate (BP) administration. Because of the peculiar pharmacokinetic and pharmacodynamic features of the BF (mainly for i.v. administration), their efficacy and large use, some major issues have to be taken into account extendedly both by oncologists and by dentists: 1) therapeutic dental protocol for patients with diagnosis of bisphosphonate-related osteonecrosis of the jaw (BRONJ); 2) dental strategies for patients in former or current i.v. BF treatment and in absence of BRONJ signs; 3) strategies for patients before i.v. BF treatment. Clinical features and guidelines for the management of this condition have been investigated and reported, sometimes with unclear indications; hence, on the basis of the literature and our clinical experience, major end points of this paper are providing our run protocols for the issues above described and, finally, focusing on a crucial, but not extensively investigated point: the early and correct diagnosis of BRONJ versus metastatic jaw lesions in cancer patients.

Abstract
AIM To determine the frequency with which the histopathological diagnosis of periapical lesions contributes to a change in the clinical diagnosis. METHODOLOGY Cases having a clinical diagnosis of disease resulting from dental pulp necrosis were selected from the database of the Oral Pathology Reference Institute between 1975 and 2005. Cases with different histopathological diagnoses were determined and information about age and gender of the patient, location of associated tooth, pulp status and the histopathological diagnosis were recorded. The percentage of nonendodontic periapical lesions was then determined. RESULTS In the 30-year period, 32,423 [corrected] biopsy specimens were received. Overall 4006 (9.13%) had a clinical diagnosis of pulpal necrosis with associated pathosis in the periradicular area. Within this group, 26 cases (0.65%) had a histopathological diagnosis of nonendodontic pathology. Keratocystic odontogenic tumour was the most frequent nonendodontic lesion (11 cases) in the periradicular region followed by central giant cell granuloma (three cases), chronic sinusitis (three cases) and one case each of the following lesions: nasopalatine duct cyst, lateral periodontal cyst, calcifying cystic odontogenic tumour, ameloblastic fibroma, squamous odontogenic tumour, cemental dysplasia, haemangioma, foreign body cell granuloma and amalgam tattoo. CONCLUSIONS The histopathological study of periapical pathosis can occasionally reveal nonendodontic lesions. Odontogenic tumours made up the largest group.

Abstract
Mixed odontogenic tumors in the jaws of children and adolescents usually cause dentition anomalies. The typical forms of these are ameloblastic fibroma, ameloblastic fibroodontoma, complex odontoma and compound odontoma. In the present study mixed odontogenic tumor cases are presented in patients under 20 years of age. All of them were associated with tooth eruption disturbances. Further aim of this study was to discuss the nature and interrelationships of this group of lesions. Ameloblastic fibromas (AFs) are true, mixed, soft tissue neoplasms, deriving from the proliferation of both odontogenic epithelium and mesenchyma. They have a potential to both recurrence and malignant transformation. Ameloblastic fibroodontomas (AFOs) may be regarded as hamartomas, which exhibit epithelial, mesenchymal and abundant hard tissue components of the developing teeth. Odontomas are calcifying benign hamartomas, and represent the most common type of odontogenic jaw tumors among patients less than 20y, having complex and compound variants. Complex odontomas (CXOs) are built up from amorphous hard tissue elements, and generally occur in the premolar or molar regions of the maxilla. Compound odontomas (CDOs) usually appear in the maxilla, in the region of the incisors and canines, and contain small, radio-opaque structures reminiscent of rudimentary teeth. Early diagnosis and treatment of mixed odontogenic jaw tumors in children may prevent the serious orthodontic complications and jaw deformations.
