Osteoid osteoma was first described as a distinctive benign osteoblastic tumour by Jaffe (1935). Lichtenstein (1965) defined osteoid osteoma as a small, oval or roundish tumour-like nidus composed of osteoid and trabeculae of newly formed bone deposited within a substratum of highly vascularised osteogenic connective tissue. This lesion has been reported in almost every bone but not previously ...

Osteoid osteoma is a small common benign osteoblastic tumor. Foot osteoid osteomas represent a minority of cases. Patients are usually male children and young adults within the third decade. In our case report we describe an osteoid osteoma of the calcaneus in a young adult, semi-professional basketball player. Starting from the case description, we aim to: 1) Analyse the reasons of initial mis...

BACKGROUND The hand and wrist bones are infrequent sites for osteoid osteoma, and its diagnosis can be difficult. This paper reports 25 cases of osteoid osteoma in the hand and wrist. METHODS Records of the 25 patients who had pathological conditions of osteoid osteoma of the hand and wrist were reviewed and analyzed. RESULTS Twenty-five cases of osteoid osteoma of the hand and wrist were t...

BACKGROUND Osteoid osteoma is a primary, benign bone tumour. The characteristic clinical symptom is nocturnal pain at the tumour site that decreases or resolves completely with salicylates and non-steroidal antiinflammatory drugs (NSAIDs). The typical radiological features include a radiolucent area with an osteosclerotic rim. An unusual location or absence of visible abnormalities on conventio...

Juxta-articular, subperiosteal osteoid osteomas arising around the ankle are unusual. Tumors arising on the neck of the talus commonly produce symptoms mimicking monoarticular arthritis. Patients are usually treated for arthritis or ankle sprain, which often leads to a delay in definitive diagnosis. Here we present a case of osteoid osteoma of neck of talus which was presented as ankle pain. It...

Ten percent of all osteoid osteomas are located in the spine; they represent the most common cause of painful scoliosis in adolescents. The recommended treatment is surgical excision of the nidus. Nine patients with osteoid osteoma of the spine underwent surgical treatment between 1996 and 2002. Complete nidus removal was performed in all patients and the diagnosis was made by frozen sections i...

Osteoid osteoma is a relatively frequent benign bone tumour, consisting of osteoid and woven bone, and surrounded by a halo of reactive sclerotic bone, with an average size of the nidus less than 1.5 cm. It is a condition of late childhood, adolescence and young adult age. It usually occurs in the appendicular skeleton and the spine, and is generally localised in or near the cortex. The lesion ...

Osteoid osteoma is a benign osteoblastic tumor usually seen in adolescent and young males. In the paediatric age group, since the history may be difficult to elicit, there are often problems in early diagnosis. The author reports an unusual presentation of osteoid osteoma in a ten-year-old girl, which could not be diagnosed by conventional X-rays and CT scan.

Osteoid osteoma is a benign tumor especially affecting young males generally treated with radiofrequency ablation. This is a non-invasive and safe procedure, major complications are very rare, most of them consisting in local skin burns. The present case shows a late subtrochanteric fracture in a young boy after CT guided termoablation of osteoid osteoma of proximal femur and short review of th...
