Objectives To describe the work-up and surgical management of an osteoblastoma involving the lateral skull base. Typically occurring in the spine or long bones, osteoblastomas of the craniofacial skeleton are exceedingly rare and infrequently reported. A review of the current literature regarding temporal bone osteoblastoma, diagnosis, and treatment is described. Methods This case report descri...
We report a case of benign osteoblastoma of the temporal bone and a review of the literature. Osteoblastoma is a rare bony tumor that usually develops in the long bones or in the vertebral column. To our knowledge, this is the fourth reported case of benign osteoblastoma confined to the temporal bone, and it is the second such reported case to include facial paralysis as the initial symptom. Re...
Background and Aim: Osteoblastoma is one of the rarest primary bone tumors. Although, small bones of the hands and feet are the third most common location for this tumor, the hand involvement is very rare and few case observations were published in the English-language literature. Materials and Methods: In this study, we report five cases of benign osteoblastoma of the hand...
Osteoblastoma is a benign bone tumor of osteoblastic origin. Two cases, an 8-year-old boy and a 24-year-old man, are presented. Both tumors were resected with wide surgical margins and neither patient had adjuvant radiation or chemotherapy. The patients showed no evidence of local recurrence after six to seven years. The clinical, radiological, histological and immunohistochemical features are ...
BACKGROUND Osteoblastoma is a rare and benign tumor which requires early diagnosis and surgical excision. Scoliosis is a common presentation following osteoblastoma. It is considered due to pain-provoked muscle spasm on the side of the lesion. Few researches about osteoblastoma combined with severe scoliosis have been reported. CASE PRESENTATION A 14-year-old girl presents with progressive sc...
Osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. It mostly affects the vertebral column and long bones. Radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. Herein, we report a ca...
Osteoblastomas are rare neoplasms of the spine. The majority of the spinal lesions arise from the posterior elements and involvement of the corpus is usually by extension through the pedicles. An extremely rare case of isolated C2 corpus osteoblastoma is presented herein. A 9-year-old boy who presented with neck pain and spasmodic torticollis was shown to have a lesion within the corpus of C2. ...
Benign osteoblastoma (OB) is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. Vertebral column, sacrum, long bones, and calvarium are more frequent sites of this tumor. Clinically, patients present with pain and swelling. Histologically, contain a well vascularized, osteoblastic connective tissue stroma and occasionally, osteoclasts along with osteoid an...
OBJECTIVES/HYPOTHESIS Osteoblastoma is a slow-growing, locally destructive benign bone neoplasm, rarely occurring in the laryngeal cartilage. We present the case of a professional voice user diagnosed with laryngeal osteoblastoma after microdirect laryngoscopy and endoscopic biopsy. Her treatment required a unique operation, with elements of partial laryngectomy and maintenance of vital endolar...
Osteoblastoma is a very rare primary bone tumour in the maxillofacial region. We report 2 cases of osteoblastoma in the maxilla and mandible, respectively. Histologically, the tumour is composed of small, irregular bony trabeculae and osteoids that are separated by a vascular stroma, and it should be considered in the differential diagnosis of an osteoblastic lesion. Total surgical resection is...
