Osteoblastoma is a benign bone tumor with a slow growing and local aggressive nature. This tumor type is usually localized in the cervical vertebra and rarely involves laryngeal cartilage structures. Very few osteoblastoma cases have been reported in the literature. Here we present laryngeal osteoblastoma originating from arytenoid cartilage in a patient with a history of cordectomy due to glottic squamous cell carcinoma.

Review
Osteoblastomas located on the surface of cortical bone, so-called periosteal (juxtacortical) osteoblastomas, are extremely rare. A 24-year-old man complained of pain and swelling in the left knee. The clinical and radiological investigation showed a tumor located in the posterior portion of the distal shaft of the femur. The radiological differential diagnosis included parosteal osteosarcoma, periosteal chondroma and periostitis ossificans. A frozen section was obtained and histology revealed an osteoblastoma with large epithelioid-appearing osteoblasts consistent with an aggressive osteoblastoma. An en bloc resection of the tumor was performed and the definitive histology of the whole specimen revealed a typical osteoblastoma. The authors draw attention to the fact that periosteal osteoblastoma is a rare tumor that could be mistaken clinically and histologically for other and more common tumors at this location.

Review
BACKGROUND
Osteoblastoma is a benign bone tumor accounting for 1% of all bone tumors; it commonly involves the spine and the sacrum of young individuals, with less than 5% being localized to the posterior mandible. In view of its rarity in the maxilla and mandible, osteoblastoma is rarely diagnosed as such in the absence of interdisciplinary cooperation.
METHODS
A retrospective study of four benign osteoblastomas was performed based on a review of the clinical, radiographic, and histopathologic features of all cases.
RESULTS
The tumors involved the posterior mandible of young patients (age range, 10-21 years; two male and two female patients) and appeared as painful bone expansions. Radiologically, they were poorly defined, radiolucent/radiopaque lesions containing calcifications and not showing sclerotic borders or periosteal reactions. Histologically, they were composed of osteoid and woven bone surrounded by plump osteoblast-like cells with interposed fibroblasts, inflammatory cells, and red blood cells. All patients were disease free after prolonged follow-up.
CONCLUSIONS
Osteoblastomas may be distinguished from other bone tumors, fibro-osseous lesions, and odontogenic neoplasms on the basis of integrated clinical, radiologic, and histologic features and usually manifest an indolent clinical course.

We present a case of rib osteoblastoma in a patient with NK/T cell lymphoma. Osteoblastoma was incidentally found in a 63-year-old man in the axillary segment of the fifth rib and was misdiagnosed as lymphomatous involvement on staging 18F-FDG PET/CT. The radiological features in the CT component of PET/CT were atypical. After surgery, the diagnosis of osteoblastoma was confirmed by histopathologic findings.

Osteoblastoma is a rare, benign type of osteoblastic tumor. It constitutes approximately 1% of all primary bone tumors. Osteoblastoma most commonly affects the long bones; it very rarely affects the jaw bones. Because of its clinical and histological similarity with other bony tumors, such as osteoid osteoma and fibro-osseous lesions, osteoblastoma is a diagnostic challenge. Very few cases of osteoblastoma involving the maxillofacial region have been reported to date. We herein describe a 15-year-old female patient with osteoblastoma that presented as a palatal swelling of 6 months' duration.

Review
The authors describe 2 cases of osteoblastoma of the calvaria and review the clinical features of the 28 cases reported in the world literature. Benign osteoblastoma is a rare tumor that effects young patients, most frequently at temporal level. On the basis of its neuroradiological appearance, it is difficult to formulate a differential diagnosis against other osteoblastic tumors or against osteoid osteoma. In only a few cases MRI findings are reported. In our cases, MRI was more effective than CT scans and radiographs for evaluating the intracranial and intraosseous extension of the tumor. The definitive diagnosis was obtained by combining the histopathological features of the tumor with the clinical and radiological data. The prognosis of this tumor is very good regardless of the type of treatment performed, although both relapse and, more rarely, malignant tumor evolution are possible.

Osteoblastoma is a rare benign osteoblastic tumor accounting for less than 1% of all bone tumors; approximately 10% to 12% of cases occur in the maxillofacial skeleton. This case report describes the clinical, imaging, and histopathologic findings of an atypical osteoblastoma occurring in the mandible of a 60-year-old man. The characteristics of the lesion and the differential diagnosis from other bone pathoses are reviewed.

INTRODUCTION
Osteoblastoma is a benign, aggressive and rare osteoblastic tumor. Its most common location is in later elements of the spine and sacrum. The cuboid presentation is exceptional.
CASE REPORT
A 50-year-old male who began her condition in 2005, with pain and increased volume in the dorsolateral region of the middle foot. X-rays show bone grafting and a cuboid lesion, radiotransparent, heterogeneous, multilobed, with irregular edges that exceeds the lateral cortical. Angiotomography was performed where hypervascularized injury was observed; bone scan showed uptake of technetium 99, and MRI reported an injury with post-surgical, cystic and multilobed changes. Trans surgical biopsy was taken, increased atypia-free cellularity and few multinucleated giant cells were reported and Enneking 2 qualified. Treatment was initiated with resection of the tumor, cryotherapy, and placement of tricortical graft in the bone defect. He exhibited good post-surgical evolution. At three years of the surgical procedure, he's without tumor and asymptomatic. Although osteoblastoma does not usually occur in cuboid, it should be taken into account as a differential diagnosis.
CONCLUSION
Bone tumors, despite having common locations, can occur in rare areas and therefore the complete radiographic and histopathological clinical study in each patient is critical.

Review
UNLABELLED
BACKGROUND/SUBJECT: A rare case of osteoblastoma of the third cervical vertebra (C3) occurring in a 16-year-old adolescent is presented. He was admitted suffering from neck pain for more than 3 years.
METHOD
Plain X-rays, technetium bone scanning, CT scan and MRI indicated an expansile, partially sclerotic lesion of the C3 involving the superior facet and pedicle on the right side. The lesion was excised through a posterior approach.
RESULT
Even though the 18-month follow-up is still a very short interval in our case, the subject's neck pain has resolved completely and there has been no sign of tumor recurrence in the recently taken imaging. There has been no clinical or radiologic sign of instability in the follow-up investigations. To the best of our knowledge, this is the third case of C3 osteoblastoma reported in the literature, highlighting the predilection of the reported cases to occur in 14- to 16-year-old boys.
CONCLUSION
A full investigation is indicated in youngsters suffering from persisting neck pain and complete resection of the lesion can prevent recurrence and malignant transformation. Long-term follow-up is needed to declare a lifelong cure of the disease.
