Osteomas are benign, slow-growing osteogenic tumors commonly occurring in the craniofacial bones. Osteomas are characterized by the proliferation of compact and/or cancellous bone. It can be of a central, peripheral, or extraskeletal type. The peripheral type arises from the periosteum and is rarely seen in the mandible. The lingual surface and lower border of the body are the most common locations of these lesions. They are usually asymptomatic and can be discovered in routine clinical and radiographic examination. In this paper, we presented a large solitary peripheral osteoma located in the buccal surface of the left posterior mandible and causing facial deformity in a 37-year-old woman. Radiographic examination by computed tomography revealed radiopacity with a well-circumscribed, pedunculated mass approximately 3 cm in size. The osteoma was removed surgically, and no recurrence has been observed.

Brown tumor is a non-neoplastic lesion which resulting from abnormal bone metabolism caused by hyperparathyroidism. We report a rare case of peripheral brown tumor related with primary hyperparathyroidism which simulating a peripheral giant cell granuloma of the jaws. [Med-Science 2014; 3(4.000): 1751-61]

WOS: 000282003300058 PubMed: 20856051 Cherubism is a rare, nonneoplastic, fibro-osseous disease. It is an autosomal-dominant disorder in which the normal bone is replaced by cellular fibrous tissue and immature bone. It is genetically inherited, although many nonfamilial cases have been reported. Cherubism is a bone disease clinically characterized by bilateral, painless enlargements of the jaws. The mandible is the most severely affected craniofacial component, in which uncontrolled growth of the malady deteriorates the aesthetic balance of the face. A malocclusive and abnormal dentition, worse in the mandible, can be seen. Histopathologically, numerous randomly distributed multinucleated giant cells and vascular spaces within a fibrous connective tissue stroma with or without eosinophilic collagen perivascular cuffing were apparent. The appearance of the affected children is normal at birth. Between the ages of 2 and 7 years, swellings within the mandibular body or tuberosities of maxilla appear. This article relates to a postpubertal nonfamilial cherubism case that was noticed with multiple radiolucencies in radiographic examination and its effects on teeth.

WOS: 000276073200030 PubMed: 20216457 Osteomas of the jaws are rare osteogenic lesions considered to be true neoplasms, characterized by the proliferation of compact and/or cancellous bone. It can be central, peripheral, or of an extraskeletal type. The central osteoma arises from the endosteum, the peripheral osteoma from the periosteum, and the extraskeletal soft tissue osteoma usually develops within a muscle. However, in a previous work we have suggested that at least some peripheral osteomas may be reactive rather than neoplasms, probably associated with trauma. Some reported cases did have a clear history of trauma; however, this was not the case in the majority of cases. Whereas peripheral osteomas are fairly easy to diagnose, central osteomas pose a more challenging diagnostic problem and need to be differentiated from other similar lesions of the jaws, such as central ossifying fibroma, condensing osteitis, idiopathic osteosclerosis, osteoblastoma, cementoblastoma, and complex odontoma. With such a low number of case of central osteoma reported, the objectives of the present report are to describe a case of the central osteoma associated with partially root resorption of the mandibular first molar. Our case report participates to literature as a 11th case.

Aim To present a case of expansive focal cemento-osseous dysplasia and emphasize the importance of differential diagnosis. Background Cemento-osseous dysplasia is categorized into three subtypes on the basis of the clinical and radiographic features: Periapical, focal and florid. The focal type exhibits a single site of involvement in any tooth-bearing or edentulous area of the jaws. These lesions are usually asymptomatic; therefore, they are frequently diagnosed incidentally during routine radiographic examinations. Lesions are usually benign, show limited growth, and do not require further surgical intervention, but periodic follow-up is recommended because occasionally, this type of dysplasia progresses into florid osseous dysplasia and simple bone cysts are formed. Case report A 24-year-old female patient was referred to our clinic for swelling in the left edentulous mandibular premolarmolar region and felt discomfort when she wore her prosthetics. She had no pain, tenderness or paresthesia. Clinical examination showed that the swelling in the posterior mandible that was firm, nonfluctuant and covered by normal mucosa. On panoramic radiography and computed tomography, a welldefined lesion of approximately 1.5 cm in diameter of mixed density was observed. The swelling increased slightly in size over 2 years making it difficult to use prosthetics and, therefore, the lesion was totally excised under local anesthesia, and surgical specimens were submitted for histopathological examination. The histopathological diagnosis was focal cemento-osseous dysplasia. Conclusion In the present case, because of the increasing size of the swelling making it difficult to use prosthetics, young age of the patient and localization of the lesion, in the initial examination, cemento-ossifying fibroma was suspected, and the lesion was excised surgically; the histopathological diagnosis confirmed it as focal cemento-osseous dysplasia. Clinical significance We present a case of expansive focal cemento-osseous dysplasia. Differential diagnosis is essential because ossifying fibroma is a real neoplastic entity.

BAS, BURCU/0000-0003-0593-3400; Kutuk, Nukhet/0000-0001-6563-1899 WOS: 000279667400021 PubMed: 20173718 Masseter muscle hypertrophy is a rare condition of unknown cause which is important in the differential diagnosis of head and neck masses, located in the cheek. Several treatment options reported for masseter hypertrophy, which range from simple pharmacotherapy to more invasive surgical reduction. Botulinum toxin type A is a powerful neurotoxin which is produced by the anaerobic organism Clostridium botulinum and when injected into a muscle causes interference with the neurotransmitter mechanism producing selective paralysis and subsequent atrophy of the muscle. Injection of botulinum toxin type A into the masseter muscle is generally considered a less invasive modality and has been advocated for cosmetic sculpting of the lower face. Botulinum toxin type A injection is considered to be a beneficial treatment modality in masseter muscle hypertrophy patients. The aim of this article is to report two cases of masseteric muscle hypertrophy which were treated with botulinum toxin type A injection. Marked changes in facial feature were achieved 3 months after the procedure.
