osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

Osteoid osteoma is a benign bone tumor, which represents approximately 10% of all benign bone tumors. When localized to the carpus, osteoid osteomas are most often seen in the scaphoid and capitate. Rarely, these tumors can also be observed in the trapezium. Given the infrequency with which osteomas are located in the trapezium and often nonspecific presenting symptoms, diagnosis of this tumor ...

Only seven cases of osteoma arising in the middle turbinate have been reported to date. We report the eighth case, involving osteoma in the middle turbinate of a child. This young boy was initially examined at the age of nine for the main complaint of nasal obstruction. Although a large osteoma with a maximum diameter of 30 mm was observed on computed tomography (CT), the patient was only obser...

abstract background: osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. in the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. in this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ilp) for treatment of osteoid osteoma in iranian patients. materials and methods: in this case s...

OBJECTIVE To see if the results of managing osteoid osteoma with medical treatment alone is comparable to those after surgery or other ablative therapy. DESIGN A case series. SETTING A tertiary care centre. PATIENTS Eleven patients with osteoid osteoma treated over a 5-year period. The condition was diagnosed from a typical history, patient age, standard radiography, computed tomography, ...

The effects between minimally invasive percutaneous laser ablation and open surgery in the treatment of children with osteoid osteoma were compared in the present study. A total of 72 cases of children with osteoid osteoma were divided into control and observational groups, containing 36 cases in each group. The control group underwent conventional open surgery while the observational group und...

Note Osteoid osteoma (OO) is defined as a benign boneforming tumour characterized by small size, limited growth potential and disproportionate pain (WHO, 2002). Usually, OO is solitary, although the literature shows few reports of multiples lesions in the same patient, but not concomitant. In most cases, OO patients complain of severe nocturnal pain that usually responds to salicylates and nons...

The present report describes a case of osteoid osteoma of the trapezoid. It'is an unusual localisation. Synovitis was the first clinical symptom. Tomograms allowed diagnosis and guided the treatment. Radical excision prevented recurrence.

Osteoid osteoma is a small tumor of bone which affect spine in 10% of cases. The tumor has tendency to neural arc and the lumbar spine is most common site of presentation. Lesions of odontoid process are very rare. We present a 20-year-old man who had cervical pain for 8 month. The pain respond to medical therapy. After investigation there was a lytic lesion at the odontoid process with charact...
