Benign osteoblastoma is an uncommon primary bone tumor, extremely rare in calvarium. We present a case of a 25-year-old female with an osteoblastoma of parietal bone which was totally resected. The authors discussed the clinical presentation, radiographic finding, differential diagnosis and management of the benign calvarial osteoblastoma with a review of the literature.

Osteoblastoma is a relatively rare benign bone tumor representing less than 1% of all bone tumors. The tumor usually involves the spine and sacrum of young individuals, less than 10% being localized to the skull, and nearly half of these affect the mandible, especially the posterior segments. In clinical finding, osteoblastoma present mainly with pain, swelling, and expansion of bone cortex. Radiographic appearances are variable, but frequently a well-delineated radiolucent lesion containing varying amounts of mineral deposits is seen. Histologically, ostoeblastoma is consists of irregular trabeculeae of osteoid and immature bone present within highly vascular connective tissue matrix. Osteoblastoma must be differentiated from a number of bone-producing lesions, including osteoid osteoma, fibrous dysplasia, ossifying fibroma, fibrous dysplasia, and osteosarcoma. If diagnosis may be mistaken for osteosarcoma, there are risks of more aggressive and irreversible treatment. Differential diagnosis of osteoblastoma is important. The preferred treatment of osteoblastoma is conservative approach and surgical excision. Recurrence following surgical intervention is rare. We treated osteoblastoma located in premolar area of mandible by excision with preservation of vital structure, such as nerves and teeth. So we report our clinical treatment with literature review

Osteoblastoma is an uncommon lesion of bone that occurred in jaw bone. The etiology of the Osteoblastoma is still undiscovered. The most frequent symptom is consistent pain which is often severe, and localized swelling and bone expansion mat occur. We experienced a case of osteo-blastoma which occurred on the lingual surface of mandibular body. It resembled tours mandibularis clinically, alveolar abscess radiologically. Biopsy was done to evaluable the tours-like bony mass. The results of excisional biopsy demonstrated an osteoblastoma. The symptoms are subsided and no signs related with recurrence have been noted. Our experience and many literatures demonstrated that Osteoblastoma must be included in differential diagnosis of bone-producing lesion.

Osteoblastoma is a rare benign neoplasm formed by osteoid tissue and well-vascularized bone that occurs mainly in children and adolescents. It appears primarily in the long bones, vertebral column, and small bones of the hands and feet, and not typically in the skull and maxillary bones. The purpose of this study is to present the case of an 8-year-old girl with a diagnosis of right mandibular osteoblastoma and a review of the relevant literature. The goals of treatment were to preserve dental occlusion, masticatory function and facial symmetry while minimizing the effects on patient body image and quality of life. Osteoblastoma, although it is benign, can be aggressive, and its treatment will depend on the timing of diagnosis, size and location. Early diagnosis is essential to avoid not only radical surgery as in the case presented, but also to help minimize the risk of possible relapse and potential malignancy of a benign osteoblastoma.

Typical osteoblastoma is generally considered to be a rare benign primary bone tumor that is seen primarily in children and young adults and curable by complete excision. However, the recurrence, aggressive behavior, or malignant transformation of this lesion was reported in some cases. It is reported that the malignant or aggressive osteoblatoma is really osteoblastoma-like osteosarcoma. Therefore, although this lesion is diagnosed as benign histologically. the operator must observe the postoperative course carefully. This article is to report a case of osteoblastoma-like osteosarcoma occurred in the mandible of 22 years old male patient with literature review.

Osteoblastoma is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. This is a neoplasm of bone characterized by a proliferation of osteoblasts forming bone trabeculae. Because the clinical feature of benign osteoblastoma is nonspecific and osteoblastoma has a pleomorphic histologic appearance, the differential diagnosis is difficult problem. We studies the case records 3 new patients with osteoblastoma. We discussed the case from clinical, radiologic, and histologic feature for differential diagnosis. Three cases from our clinic is reported and analized with previously described cases.

Benign osteoblastoma, a rare tumor which forms osteoid and woven bone, represents 3% of benign and 1% of all primary bone tumors. It can involve anywhere in the axial skeleton, which is most common in the spine (34%). But the lesion of the calcaneus is extremely rare. The ratio of males to females is 2:1, with 80 percent of the patients being under thirty years of age. Pain is the most common symptom and rarely pathologic fracture. Osteoblastoma is a benign tumor but has a high recurrence rate after intracapsular malignant change. Therefore, choice of surgical procedure is the 'enbloc' resection. Authors have experienced a case of osteoblastoma developed in calcaneus. The treatment was wide resection and triple arthrodesis. We have reported here the case in which osteoblastoma occured in calcaneus of the right foot.

골모세포종은 뼈를 생성하는 드문 양성 종양으로 척추에 주로 발생하지만 장골에서 병적 골절을 발생시키는 골모세포종에 대한 보고는 거의 없다. 저자들은 상완골 간부에 골모세포종으로 인한 병적 골절에 대하여 종양은 소파술을 시행하였고 병적 골절에 대해서는 골수강내 금속정을 이용한 고정술을 시행하여 안정적인 골유합을 얻을 수 있었다. 저자들은 이처럼 보기 드문 상완골 간부애 골모세포종으로 인한 병적 골절을 진단하고 치료하는 경험을 하였기에 이에 관한 증례를 보고하고자 한다.

This report presents a rare case of maxillary osteoblastoma in a 17-year-old female. The patient presented with dull pain and facial asymmetry inferior to the left zygoma. An intraoral examination found a painless swelling on the buccal gingival tissue in the left posterior maxilla. Panoramic radiographs and multidetector computed tomographic images revealed an ill-defined, non-corticated, mixed attenuating entity of osseous density located within the left posterior maxilla apical to the left maxillary molars. The entity exhibited a heterogeneous internal structure with a fine granular appearance, and the periphery showed a partial hypo-attenuating rim along the antero-medial aspect. Expansion of the left posterior maxilla accompanied with displacement of the left maxillary sinus floor was noted. External root resorption of the first and second molars was noted, as well as postero-superior displacement of the third molar. The histopathologic diagnosis of the biopsy was osteoblastoma. Complete excision of the tumor was performed.
