Osteomas are benign, bone-forming tumours located within bones or developing on them. In the head and neck region they are commonly seen in the frontoethmoidal region. Occipital osteomas are very rare tumours. They are often asymptomatic and are incidentally found on radiological investigations. The main clinical symptom is headache of varying intensity and quality, though some patients may com...

A 35-year-old woman presented with visual field abnormality in the left eye (OS). Her best-corrected visual acuity with Landolt ring chart was 1.0 OS. The funduscopic examination revealed a yellowish dome-shaped choroidal tumor located...

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 pres...

Peripheral osteoma is the most common subtype of osteoma that arises most frequently in the craniofacial bones. It may occur at any age with a male-to-female ratio of 2:1. Peripheral osteoma may affect the mandible, particularly the ramus and the condyle. Compound odontoma is a subtype of odontoma that occurs in young subjects without gender predilection. It affects the maxilla more frequently ...

This paper reports on apparently the first case of a pharyngeal osteoma that developed from the hyoid bone. An 84-year-old man's, presenting symptom was a slight throat pain. Endoscopic examination revealed a huge mass occluding the pharyngeal space. CT scan of the neck showed a large osseous mass adjacent to the hyoid bone. Transoral resection with tracheostomy was performed. Histopathological...

Osteoid osteoma is a benign bone tumor and accounts for 10% of benign tumors. Almost any bones can be involved but half of cases involving femur or tibia. Osteoid osteoma is a rare tumor of the scapula with only 18 reported cases in the literature. We presented a case of osteoid osteoma of the scapula in right shoulder in angle of coracoid and geloneid in a 34- year old woman. She had right rad...

Osteoid osteoma of the base of coracoid process is a rare location. They may present simply as diffuse shoulder pain. Careful evaluation of the patient is important to diagnose this rare lesion. Clinical history...

BACKGROUND The most important symptom in patients with osteoid osteoma and osteoblastoma is a resistant localized neck pain and stiffness in the spine. OBJECTIVE To evaluate and analyze 6 cases of osteoid osteoma and osteoblastoma of the cervical spine that were surgically treated over a 7-year period and to emphasize the unusual persistent neck pain associated with osteoid osteoma and osteob...

A case of cervical osteoid osteoma is reported, with a brief account of the diagnosis and treatment of these lesions. Cervical osteoid osteoma is rare but its pattern of presentation varies little and it should therefore be possible to suspect it on clinical grounds alone. Bone scanning is now regarded as more efficient than radiography in identifying the lesion but X-ray tomography will normal...
