The Use of Denosumab in Osteoblastoma of the Metacarpal.

J Hand Surg Am 2019 Mar 22. Epub 2019 Mar 22.

Granovsky-Gluskin Division of Orthopaedic Surgery, Mount Sinai Hospital, Toronto, Ontario, Canada; Division of Orthopaedic Surgery, Department of Surgery, University of Toronto, Toronto, Ontario, Canada.

Osteoblastoma is a benign aggressive primary bone tumor that occasionally presents in the hand. Because surgical treatment remains the mainstay of treatment, there are no established nonsurgical pharmacological options for patients in whom resection is not feasible. Novel therapies, such as denosumab, are currently being investigated in primary bone tumors. Read More

Osteoblastoma of the clavicle at the site of a previous fracture-first case report and review of the literature.

Skeletal Radiol 2019 Mar 8. Epub 2019 Mar 8.

Division of Musculoskeletal Imaging and Intervention, Department of Radiology, Massachusetts General Hospital, 55 Fruit Street Yawkey 6E, Boston, MA, 02114, USA.

Osteoblastoma is a rare, benign primary tumor of bone, accounting for < 1% of all bone tumors. We report the case of a 27-year-old female who developed pain and swelling five and a half years after a clavicular fracture and was subsequently found to have an osteoblastoma arising at the fracture site. This is the first reported case of an osteoblastoma developing after a fracture, although osteoid osteomas, which are histologically indistinguishable from osteoblastomas, have been reported at prior fracture sites.

Atypical "Sclerosing" Osteoblastic Neoplasm: A Tumor of Intermediate Biological Potential Between Usual Osteoblastoma and Conventional Osteosarcoma.

Am J Surg Pathol 2019 May;43(5):610-617

Departments of Anatomic Pathology.

The existence of "aggressive" osteoblastoma (OB) or malignant transformation of OB is controversial. Over a few decades, we have encountered a group of "borderline" sclerosing osteoblastic lesions that are difficult to classify, tending toward local recurrence, especially following curettage. A search of the consultative and institutional files from 3 co-authors for atypical OB, malignant transformation of OB, well-differentiated osteosarcoma (OS), and OB-like OS diagnoses revealed 8 similar cases.

Case report of epithelioid osteoblastoma of the mandible: findings on positron emission tomography/computed tomography and review of the literature.

Oral Surg Oral Med Oral Pathol Oral Radiol 2018 Dec 31. Epub 2018 Dec 31.

Associate Professor of Clinical Specialty, Department of Diagnostic Radiology, American University of Beirut Medical Center, Beirut, Lebanon. Electronic address:

Epithelioid osteoblastoma is a clinically aggressive subtype of osteoblastoma that favors the mandible and the maxilla. Its histologic features lie on a spectrum between conventional osteoblastoma and low-grade osteosarcoma, thus making it difficult at times to confirm the diagnosis. It is known to have a high risk of recurrence after surgical resection, but it is a benign entity and does not have the propensity to metastasize. Read More

CT-guided percutaneous cryoablation of an osteoid osteoma of the rib.

Radiol Case Rep 2019 Mar 4;14(3):400-404. Epub 2019 Jan 4.

Creighton University School of Medicine, Phoenix Regional Campus, St. Joseph's Hospital & Medical Center, 350 West Thomas Road, Phoenix, AZ 85013, USA.

An osteoid osteoma is a benign bone tumor that arises from osteoblastic dysfunction and usually presents as nonspecific, nocturnal pain located in the diaphysis of long bones, with <1% occurring in the ribs. It is most commonly treated with nonsteroidal anti-inflammatory drugs or merely observed; when these treatments do no prove efficacious, either open surgery or interventional ablation are pursued. Herein, we report a rare case of an osteoid osteoma located in the rib of a 19-year-old male that was histologically diagnosed through computed tomography (CT)-guided biopsy. Read More

Osteoid osteoma: multimodality imaging with focus on hybrid imaging.

Eur J Nucl Med Mol Imaging 2019 Apr 19;46(4):1019-1036. Epub 2018 Oct 19.

Department of Radiology and Nuclear Medicine, Cantonal Hospital Lucerne, Lucerne, Switzerland.

Osteoid osteoma is a painful, benign, osteoblastic lesion that occurs in younger patients and affects the extremities or the axial skeleton. While plain film findings may suggest the diagnosis, in complex anatomical regions such as the spine, pelvis, wrist and foot advanced imaging modalities are often required. A typical nidus surrounded by sclerosis or cortical thickening characterizes osteoid osteoma on plain radiography and CT. Read More

Radiologia 2019 Mar - Apr;61(2):167-170. Epub 2018 Sep 28.

Servicio de Diagnóstico por Imágenes, Hospital Italiano de Buenos Aires, Ciudad Autónoma de Buenos Aires, Argentina.

Sternal tumours are rare in children. The differential diagnoses include a wide spectrum of benign (from bone cyst to osteoblastoma, osteochondroma and fibrous displasia) and malignant tumours (Ewing's sarcoma, chondrosarcoma rhabdomyosarcoma), inflammatory lesions and infectious processes. The SELSTOC (Self Limiting Sternal Tumours of Childhood) are entities of non-specific origin, they are self-limiting and characterised by a rapidly growing tumour that disappears spontaneously with no history of trauma or active infection.

Cytological diagnosis of osteoblastoma of the talus: Case report with unusual presentation and diagnostic pitfalls.

Cytojournal 2018 27;15:20. Epub 2018 Aug 27.

Department of Orthopaedics, Himalayan Institute of Medical Sciences, Dehradun, Uttarakhand, India.

Osteoblastoma is a rare bone tumor mostly affecting the young adults and commonly involving the spinal cord and long bones. Talus is the uncommon site of presentation, and if involved, then the neck is more commonly involved than the body of talus. The cytological diagnosis of osteoblastoma is limited, and to the best of our knowledge, its fine-needle aspiration (FNA) in the talus has still not been reported in the literature. Read More

J Surg Oncol 2018 Jun 3;117(8):1786-1798. Epub 2018 May 3.

Queen Elizabeth II Health Sciences Center, Halifax Infirmary, Dalhousie University, Halifax, Nova Scotia, Canada.

Bone tumors are relatively rare in the foot and ankle region. Many of them present as cystic lesions on plain films. Due to the relative rarity of these lesions and the complex anatomy of the foot and ankle region, identification of such lesions is often delayed or they get misdiagnosed and mismanaged. Read More

Future Oncol 2018 Dec 25;14(28):2945-2955. Epub 2018 Apr 25.

Department of Biotechnology & Applied Clinical Science, University of L'Aquila, L'Aquila, Italy.

Interventional radiology has experienced an exponential growth in the last years. Nowadays it is possible to treat painful benign lesions or metastases with optimal results in terms of pain management and disease control. Among the benign lesions, osteoid osteoma is the most frequently treated with minimal invasive techniques and the results are excellent. Read More

Eccentric, mature osseous cap: A distinct imaging feature of sinonasal osteoblastoma.

Am J Rhinol Allergy 2018 Mar 23;32(2):82-84. Epub 2018 Mar 23.

2 Rush Sinus Program, Department of Otorhinolaryngology-Head and Neck Surgery, Rush University Medical Center, Chicago, Illinois, and.

Background: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. Read More

Fluorescent In Situ Hybridization for TP53 in the Diagnosis of Pediatric Osteogenic Sarcoma.

Am J Surg Pathol 2018 Jun;42(6):744-749

Division of Pathology.

Osteogenic sarcoma (OS) is the most common malignant bone tumor in children and adolescents. Despite advances in molecular genetic characterization of pediatric and adult tumors, the diagnosis of OS still depends almost entirely on light microscopy. The lack of consistent genetic changes in OS has greatly hindered the development of any diagnostic molecular test. Read More

Large Paediatric Central Osteoma with Osteoblastoma-Like Features in the Mandible.

Head Neck Pathol 2018 Mar 5. Epub 2018 Mar 5.

Consultant Oral and Maxillofacial Surgeon, Monash Health, Melbourne, VIC, Australia.

The diagnosis of osteomas in the paediatric population can pose a challenge to pathologists in excluding malignant bony tumours. We present the case of a 10-year old male presenting with a large left mandibular radiopaque lesion. This paper discusses the case of a central osteoma with osteoblastoma-like features, literature review, differential diagnosis of radiopaque lesions of the maxilla and mandible as well as a detailed discussion of the pathology of the lesion.

Osteoblastomatosis: an unusual diagnosis and treatment.

Skeletal Radiol 2018 Aug 15;47(8):1183-1189. Epub 2018 Feb 15.

Complejo Hospitalario Univeritario de Ferrol, A Coruña, Spain.

Osteoblastomatosis (OBLT), also referred to as multifocal osteoblastoma (OB), is an unusual and recently described entity consisting of multifocal tumors histologically consistent with osteoblastoma and osteoid osteoma (OO) but radiologically mimicking a vascular bone lesion. OBLT treatment is based on aggressive procedures, such as amputation, en bloc resection, and chemotherapy. Only one previously reported case was successfully treated following a multimodal approach consisting of curettage, cryotherapy, intravenous bisphosphonates, and radiofrequency ablation. Read More

Eur Spine J 2018 07 29;27(Suppl 3):477-482. Epub 2018 Jan 29.

Orthopaedics Department, Centro Hospitalar Lisboa Norte, University Hospital of Santa Maria, Avenida Professor Egas Moniz, 1649-035, Lisbon, Portugal.

Introduction: The anterior elements of the spine, particularly the odontoid processes, are a rare location for osteoblastomas. Pseudomalignant osteoblastomas are themselves rare histologic types and are also extremely rare in this location. Most osteoblastomas are Enneking stage 2 lesions; less frequently, they can be more aggressive with extra-capsular extension (Enneking stage 3). Read More
