Osteoid osteomas are characterized clinically by a pattern of nocturnal pain which is exquisitely sensitive to salicylates. Etiology for the pain has been ascribed by previous investigators to the presence of nonmyelinated nerve fibers or to the effect of prostaglandins. In an effort to corroborate
Osteoid osteoma is a tumour of bone characterised by pain which is relieved by aspirin and nonsteroidal anti-inflammatory drugs. Very high levels of prostaglandins have been found in the lesion. In five patients with osteoid osteoma, prostaglandin E2 (PGE2) and prostacyclin (PGI2) synthesis in the
The joint is a relatively rare localization for osteoid osteoma. The location of the tumor and the concomitant synovitis-explain the peculiarity of the clinical features, which makes differential diagnosis with inflammatory diseases of the joint difficult. The authors report the results of three
Osteoid osteoma is a benign bone tumor characterized by local pain that typically increases at night. The tumor commonly occurs in the long bones of the lower extremities, and in rare instances in cranial bones. Here we report the case of a 25-year-old man diagnosed with an osteoid osteoma of the
We reported a case of osteoma involving the frontal recess, which presented as frontal headache and reviewed literatures. Also, this case highlights that sinunasal osteomas can cause pain by local mass effects, referred pain, or prostaglandin E2-mediated mechanisms.
BACKGROUND
Osteoid osteoma is a benign bone lesion characterized by nocturnal pain mostly, which may be relieved by non-steroidal prostaglandin inhibitors. Treatment by complete resection of the nidus immediately relieves the pain. Intraoperative location of the nidus may be difficult, and extensive
Forty patients (27 males and 13 females) aged 18 months-41 years with preliminary diagnosis of osteoid osteoma localized within lower limb were reviewed. All underwent surgery. Histopathology confirmed previous diagnosis in 29 patients but in 11 cases (30%) histology either gave different diagnosis
Osteoid osteoma is a nonmalignant tumour that rarely localizes intraarticularly. When this happens, the tumour provokes arthritis and its recognition is delayed from months to years. We report the case of a 34 year old man with a previously known HIV infection, but no evidence of immunosuppression.
BACKGROUND
Osteoid osteoma is the third most common benign bone tumor and typically induces pain that is worse at night.
OBJECTIVE
To identify the epidemiological, pathogenetic, histological and radiological characteristics of osteoid osteoma and to present the broad variety of treatment
Osteoid osteoma was first described by Jaffe in 1935 as a benign bone neoplasm mainly located in the diaphyseal areas of long bones: 10% are located in the spine, mainly in the lumbar and thoracic posterior elements. Therapy is required due to nocturnal pain independent of the physical load and
Osteoid osteoma (OO) is a benign bone neoplasm consisting of a central prostaglandin-secreting nidus surrounded by a zone of reactive sclerosis. The diagnosis is suspected in children and young adults with longstanding nighttime pain that is relieved by salicylates or nonsteroidal anti-inflammatory
Osteoid osteomas are common lesions, constituting one-eighth of the benign bone tumors. Their size (less than 1.5 cm) and characteristic radiographic and clinical presentation are usually diagnostic. Response to salicylates is quite variable and not a reliable sign. Extremely high levels of
Osteoid osteoma is a benign osteoid-forming tumor of the bone characterized by pain which is relieved by nonsteroidal anti-inflammatory drugs. Very high levels of prostaglandins have been found in the lesion. In nine patients with osteoid osteoma, prostaglandin E2 (PGE2) and prostacyclin (PGI2)
Osteoid osteomas are benign bone-forming tumors that despite their small size (<2.0 cm) characteristically produce severe nocturnal bone pain that is relieved by aspirin. This typical clinical presentation is virtually unique among bone tumors. Histologically, osteoid osteomas are circumscribed
