Osteoma is a benign osteogenic neoplasm microscopically consisting of proliferation of cancellous or compact bone. Peripheral osteomas (PO) arise from the periosteum and are quite uncommon in the jaw bones. POs of mandible are considered as rare entity and very few cases have been reported in the literature. The pathogenesis of PO is unclear. Some investigators consider it a true neoplasm, while others believe it as a developmental anomaly, a reactive mechanism due to trauma or infection. The purpose of this article is to present the clinical, radiographic, surgical and histological features of a solitary peripheral osteoma of the mandible in a 43-year-old woman and to review the literature for PO located in the mandible.

BACKGROUND
Choroidal Osteoma is a rare, typically monolateral benign ossifying tumor of the choroid found in healthy females aged 10 to 30 years. In contrast, multiple idiopathic sclerochoroidal calcifications occur in elderly otherwise healthy subjects. Local or generalized distortions of calcium phosphate metabolism may cause secondary choroidal calcifications.
PATIENT
We report on a 56-year-old woman, who underwent removal of a histologically verified osteoma 2 years ago. Ophthalmoscopically, there were multiple prominent choroidal tumors in the inferior midperiphery of both eyes. Ultrasonography showed high reflectivity and marked shadowing posterior to the lesion. CT-scan demonstrated the presence of calcifications. The patient neither belonged to the age group, in which choroidal osteomas are typically found, nor were the lesions located in the typical manner as reported in literature. The location in the inferior choroid has not yet been described for idiopathic sclerochoroidal calcifications. The presence of secondary choroidal calcifications was very unlikely, as there was no history of ocular inflammation or systemic disease such as hyperparathyreoidism or chronic renal failure.
CONCLUSION
Thus, despite the lack of histologic examination, one may assume the rare incidence of bilateral choroidal osteomas in atypical inferior localisation in our patient.

Craniofacial osteomas may be located either superficially or intraosseously on any bone of the cranium or face or within a paranasal sinus. Osteomas within the paranasal sinus account for 0.01% to 0.43% of patients; of these, up to 80% occur in the frontal sinus. An osteoma of maxillary sinus is extremely rare. We describe a rare case of osteoma of a 56-year-old Asian woman in the maxillary sinus.

Osteomas are located mostly in the mandible followed by paranasal sinuses such as frontal sinuses, ethmoid air cells, maxillary sinuses and rarely based on nazal cavitiy or turbinate. The osteoma located on outside of nazal bone is extremely rare. The authors report an unusual patient of nasal bone osteoma associated with aesthetic problem on nasal dorsum. Outer side of nasal bone osteoma in large diameter causes aesthetic problems. The authors believe that open rhinoplasty approach is successful in this type of patients.

Review
This article discusses radiofrequency energy as a treatment of musculoskeletal tumors,focusing on osteoid osteomas. The technique has also been applied to a number of different primary musculoskeletal tumors and is increasingly being used as a palliative method in the management of painful skeletal metastases. Radiofrequency treatment of musculoskeletal tumors can be of great clinical value. When the low-power, highly limited methods are applied to small tumors such as osteoid osteomas, the technique is effective and exceptionally safe. Creation of larger thermal lesions, however, can be accompanied by significant risks, and the risk-to-benefit ratio should be carefully considered before undertaking such a treatment.

Review
Choroidal osteomas are rare benign ossifying tumors that appear as irregular slightly elevated, yellow-white, juxtapapillary, choroidal mass with well-defined geographic borders, depigmentation of the overlying pigment epithelium; and with multiple small vascular networks on the tumor surface. Visual loss results from three mechanisms: Atrophy of the retinal pigment epithelium overlying a decalcified osteoma; serous retinal detachment over the osteoma from decompensated retinal pigment epithelium, and most commonly from choroidal neovascularization. Recent evidence points to the beneficial effects of intravitreal vascular endothelial growth factor antagonists in improving visual acuity in serous retinal detachment with or without choroidal neovascularization.

Review
The authors report two cases of mastoid osteoma: it is a rare benign tumor attached to the cortex of the mastoid bone, approximatively fifty cases have been described in the english language literature and eight in the french literature. The clinical and radiological characteristics combined with histopathologic evidence demonstrate the diagnosis of mastoid osteoma, the most common type being the compact osteoma. Differential diagnosis should be considered with others benign bone-forming lesions (osteochondroma, chondroma, osteoblastoma, exostosis, fibrous dysplasia...) and with malignant lesions (osteosarcoma...). Surgical removal proposed for cosmetic deformity is a simple procedure for the vast majority of small osteomas. Early surgical intervention is recommended to avoid the evolution toward giant osteoma with potential risks of surgical complications.

Osteomas of the nose and paranasal sinuses are rather common benign tumors arising in the head and neck area. The sphenoid sinus is involved in various inflammatory and neoplastic conditions; however, an osteoma arising from the sphenoid sinus proper has not been reported in the available literature. This paper reviews, in detail, osteomas of the paranasal sinuses and their incidence, and a case of a sphenoid sinus osteoma is presented with radiological and pathological findings.

Review
Osteomas are slow-growing neoplasms of the paranasal sinuses. The previously used management of symptomatic osteomas has consisted of open excision utilizing one of several approaches. Endoscopic sinus surgery offers a convenient, safe and effective alternative to open procedures and can be safely performed in well-selected cases of ethmoid osteoma. The reduced morbidity, length of stay and superior cosmetic result are distinct advantages of this technique.

Osteomas involving the middle ear and causing a functional disturbance are rare. We report a case of a patient with an osteoma arising from the lateral semicircular canal. The main symptom was vertigo and to halt this the defect of the canal was obliterated with a bone chip and fibrin glue after removal of the tumour.
