Benign osteoblastoma of the mandible: a case report

“…In the present case, en bloc resection and reconstruction was performed with an anatomicallyshaped silicon spacer to achieve not only facial symmetry, and not affect its psychological condition and self-image, but also to normal function, taking into consideration that the patient was in the process of growth. It is worth mentioning that reconstruction is important to avoid functional problems 4,8 ; the technique was complex in this case not only because of mandibular bone defects but also because of the involvement of the condyle, but function and quality of life were maintained without. The possibility of recurrence [2][3][4][7][8][9]11,12,14,16 and the potential for malignancy [2][3][4]7,14,16 should be considered in treatment, including regular monitoring 2,3,7 .…”

“…Osteoblastoma is a rare benign tumor [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] formed by osteoid tissue and well-vascularized bone [1][2][3]5,9,10 .

Osteoblastoma agressivo recorrente da coluna cervical tratado com sucesso com radioterapia

“…2 Os osteoblastomas são, geralmente, lesões radiolúcidas, mal definidas com destruição cortical ou bordas bem-definidas e diferentes graus de mineralização. 5 Histopatologicamente, o OA apresenta proeminência nucleolar, trabécula maior e irregular, citoplasma eosinofílico e tendência a ter células mais parecidas com osteoclastos. Pleomorfismo celular leve e mitoses são observados mais frequentemente.…”
