Osteoid osteoma.
Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone that rarely exceeds 1.5 cm in greatest dimension. The lesion is most commonly located in the cortex of long bones where it is associated with dense, fusiform, reactive sclerosis. Less often, it may be cancellous, where reactive osteosclerosis is usually less intense and may be distant from the lesion. Cancellous le...
متن کاملOsteoid osteoma.
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 ...
متن کاملAn exceptional localisation of osteoid osteoma
Osteoid osteoma is a small tumor, always benign. Located preferentially on the long bones, femur and tibia, elbow location is rare. We present a case of an Osteoid osteoma in unusual subperiostal localization in the tip of the coronoid process. The lesion was removed by en bloc resection under CT-guidance. This approach enabled us to avoid damaging the proximal structures, to examine the lesion...
متن کاملOsteoid osteoma and osteoblastoma.
Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis. However, osteoblastomas are larger th...
متن کاملBone: Osteoid Osteoma
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...
