Osteoma is a rare, benign lesion wherein deposition of newly formed bone results in tumor mass. Variants osteomas can develop either as peripheral mass arising from the periosteum or central endosteum. Peripheral ones are usually asymptomatic and larger lesions primarily cause facial asymmetry. Central osteoma, most cases cortical expansion root displacement some. pose diagnostic dilemma need t...

Osteomas are benign tumors which are composed of mature compact or cancellous bone. They can be either peripheral, central or extraskeletal. The peripheral osteoma arises from surface of the bone (periosteal) whereas the central osteoma arises from the bone medullary (endosteal) and the extra-skeletal soft tissue osteoma usually develops within the muscle. Osteomas are most commonly found in th...

DESCRIPTION A 40-year-old female patient presented with a progressive hearing loss in her right ear during the last 3 months. She did not have otorrhea or otalgia. She did not report any attack of vertigo or tinnitus. On physical examination, the right external auditory canal (EAC) was completely occluded by a hard mass, which was fixed and covered with wax. Pure tone audiometry revealed a seve...

BACKGROUND Osteoid osteoma and osteoblastoma are rare, benign, bone-forming tumours. The clinical presentation, imaging study findings, and course indicate clearly that these two tumours are distinct entities. CLINICAL REPORTS We report two cases suggesting transformation of osteoid osteoma into osteoblastoma and therefore inviting a discussion of the links between these two tumours. An 11-ye...

The diagnosis of an intra-articular osteoid osteoma can be a challenging and lengthy process, with reports of delayed diagnosis of greater than 2 years. In the young, athletic patient with an atraumatic onset of groin pain, an overuse injury or muscle strain is the most likely etiology. However, an overuse injury of femoral neck stress fracture must be identified because of the potentially disa...

Osteoma is a benign, slow-growing tumor characterized by proliferation of compact or cancellous bone. It is perhaps the most common benign tumor of the sinonasal system.1 Radiologic evidence of osteoma can be present in up to 1% of all radiographs2 and up to 3% of all CT scans.3 In up to 95% of the patients the osteoma is situated in frontoethmoidal region. Osteomas of the maxillary sinus repre...

INTRODUCTION Mastoid osteoma is a rare benign tumour. In this article, the authors report two new cases of mastoid osteoma and discuss the modalities of diagnosis and management. CASE REPORTS Both patients presented with a retroauricular mass that had been slowly increasing in size over several years. The patients consulted for the cosmetic deformity induced by the lesion or moderate tenderne...

In this study, an unusual case of osteoma is presented, whereby a bone marrow osteoma was identified in the tibia. No previous cases of bone marrow osteoma have been reported. In this case, an eight-year-old male presented with discontinuous discomfort in the right distal calf for six months. Radiological examination and computed tomography revealed a radiopaque lesion within the affected bone....

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 ...

Primary osteoma cutis is characterized by the formation of normal bone tissue in the dermis or subcutis without any underlying tissue abnormality or pre-existing calcification. This illness is associated with Albright hereditary osteodystrophy (AHO), which is characterized by such physical features as a short stature, round face, obesity, brachydactyly and osteoma cutis. Pseudohypoparathyroidis...
