Osteoma of external auditory canal is a rare benign tumour. Usually slow growing, found incidentally and often symptomless. Rarely an osteoma may present as a simple aural polyp and may be mistaken as polyps arising secondary to tuberculous,chronic otitis media or carcinoma. The presentation of an osteoma as an aural polyp is extremely rare, and there have been very few reports published Here w...

We describe a unique case of a low-grade extraskeletal osteosarcoma revealing both histologic and radiologic features reminiscent of parosteal osteosarcoma. The tumor, which had been present for 10 years, occurred in the left axilla of a 74-year-old black woman. To date, all the published cases of extraskeletal osteosarcoma have been high-grade neoplasms; to our knowledge, this is the first rep...

BACKGROUND To compare the clinical and radiological features of intra-/juxta-articular osteoid osteoma and extra-articular osteoid osteoma in skeletally immature patients, paying special attention to the skeletal complications. METHODS Osteoid osteoma in 34 children (22 boys and 12 girls, mean age 10.4 years) was dichotomized according to the location of the nidus as intra-/juxta-articular (1...

Choroidal osteoma is an uncommon benign osseous intraocular tumor that typically affects young adult women. Choroidal neovascularization (CNV) is one of the complications that can develop in eyes with choroidal osteoma. We present a case of CNV secondary to choroidal osteoma treated with intravitreal ranibizumab. A 57-year-old lady presented with painless loss of vision with a right-eye visual ...

Choroidal osteoma is a unique tumor that comprises mature bone in the circumpapillary or macular region.1 Choroidal osteoma showed evolution with change in clinical features over many years, and cases of tumor growth, tumor decalcification or involution, and related choroidal neovascularization (CNV) were documented.1-4 Herein, we present a case of choroidal osteoma with serous retinal detachme...

introduction: osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. sometimes is associated with pain and functional loss. only a few cases have been reported.   case report: we describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pr...

The authors introduce a 42-year-old woman with a choroidal osteoma. After 10 years the patient presented a second choroidal osteoma in the same eye; this osteoma has been growing in the last years. New tests that were unavailable during the first diagnosis were performed such as Fundus Autofluorescence or Enhanced Depth Imaging-Optical Coherence Tomography (EDI-OCT). These tests show characteri...

Frontal sinus osteomas are mostly asymptomatic and slow-growing benign tumors most frequently involving the frontal sinus [1]. The surgical procedures available for osteoma removal can be classified into external, endoscopic, or a combination of both [2]. The external approach is often selected to ensure complete and safe removal of frontal sinus osteoma located close to both orbits [3]. Here, ...

The osteoma is a benign osteogenic neoplasm of bone. Peripheral osteoma of the mandible is uncommon. It is often asymptomatic and usually discovered when a patient complains of esthetic problems and presents for treatment. Peripheral osteomas have a characteristic clinical and radiographic appearance, but their pathogenesis is obscure. Described here are two patients with peripheral osteoma of ...

Osteoid osteoma is a benign osteoblastic tumor that is unusual in the hand. A location in the carpal bones is infrequent, which leads to errors in diagnosing it because of polymorphism of the clinical symptoms. Reviewing the literature shows that nine cases of osteoid osteoma in the scaphoid have been reported. Here, one case of osteoid osteoma in the scaphoid that was initially treated as De Q...
