An intraarticular osteoid osteoma of the knee is uncommon, and its treatment is challenging. The authors present a case of arthroscopic excision of an intraarticular osteoid osteoma in the distal femur, which was accessible through the knee joint. After confirming the nidus of the osteoid osteoma by computed tomography, the lesion was completely removed arthroscopically. The patient reported co...

Osteoma cutis is a bone formation in the dermis can to be primary or secondary forms. Only, multiples, many forms, occurring on either sex, they are a rare cutaneous disease. The pathogenesis and classification remains unclear. Our objective was the diagnostic and small invasive surgery treatment of the osteoma cutis multiple of the face, in patients as a sequel of acne. To remove the osteoma w...

Osteoma is one of the most common tumors of the cranial vault and the facial skeleton. For osteoma in the facial region, endoscopic resection is widely used to prevent surgical scarring. Tumors in a total of 14 patients were resected using an endoscopic holmium-doped yttrium aluminium garnet (Ho:YAG) laser with a long flexible fiber. Aside from having the advantage of not leaving a scar due to ...

We present a case of an intra-articular osteoid osteoma in the knee that was mistaken for a painful fabella syndrome after unsuccessful knee arthroscopy for the treatment of postero-lateral knee pain. In this case both the initial clinical presentation and the imaging proved to be deceiving. The diagnosis of intra-articular osteoid osteoma was considered only once typical clinical features appe...

Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type. Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like m...

Osteoma is a benign osteogenic lesion which is composed of well differentiated mature compact and/or cancellous bone that proliferates continuously. Its prevalence is 4%. Its pathogenesis is still controversial. Solitary peripheral osteoma of craniofacial region is a rare finding. We report a case of 30-year-old female having solitary peripheral osteoma present on the lingual cortex of the left...

Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone. The majority of the lesions arise in the cortex of long bones. Osteoid osteoma of the spine is a rare primary spine tumor and those located at the thoracal spine are even rarer. The usual treatment involves complete resection, including the nidus, or alternatively radiofrequency percutaneous ablation is performed....

Peripheral osteomas are rare tumors of jaws arising from proliferation of cancellous or compact bone increasing in size by continuous bone formation. These lesions appears as unilateral, pedunculated or seesile mushroom-like masses, well-marginated and varying in diameter from 10 to 40 mm. The first case of peripheral osteoma involving condylar process was reported by Ivy in 1927. Since then on...

We report a painless osteoid osteoma of the inner ear in an elderly woman presenting with hearing loss, tinnitus, and vertigo. CT showed a heterogeneous mass containing calcifications involving the posterior labyrinth, which heterogeneously enhanced on postcontrast MR images. Osteoid osteoma should be included in the differential diagnosis of an osteolytic petrous bone lesion with central calci...

Osteoid osteoma has been traditionally treated by curettage and en bloc resection. These methods are now being replaced by low-invasive techniques. We present the description of a percutaneous thermoablation of a femoral neck osteoid osteoma performed under CT guidance in a 22-year-old female patient.
