Epithelioid osteoblastoma or aggressive osteoblastoma of the astragalus. Presentation of a case and revision of clinical and pathological symptoms

Revista Médica del Hospital General de México, 2018
This is the case of a 58 year-old man with a painful tumour in his right ankle, resulting from a long development. An osteolytic injury was found in an X-ray, formed by bone or osteoid trabeculae surrounded by epithelioid osteoblasts and amongst these ...

Novel report of an osteogenic tumor in a late Jurassic Mamenchisaurid from Thailand. [PDF]

J Anat
Here we describe a pathology in an ulna of a Late Jurassic mamenchisaurid from Thailand. We use anatomical descriptions, CT scanning, and bone histology to identify the pathology as an osteogenic tumor. Abstract Here we report on an osseous abnormality and multiple fractures in an ulna of a subadult basal Eusauropod (Mamenchisauridae) from the Late ...

Toxic flare phenomenon in osteoblastoma: A case report with literature review

Indian Journal of Musculoskeletal Radiology, 2021
Osteoblastomas are benign neoplasm of the bone that is characterized by clinical and histological similarity to osteoid osteomas. They are larger (>1.5–2 cm) and tend to affect the axial skeleton.

Recurrent rearrangements of FOS and FOSB define osteoblastoma

Nature Communications, 2018
The transcription factor FOS has long been implicated in the pathogenesis of bone tumours, following the discovery that the viral homologue, v-fos, caused osteosarcoma in laboratory mice.

Computed Tomography and Magnetic Resonance Imaging of Bone Tumors [PDF]

, 2017
Imaging is the key to diagnosing and guiding management of bone tumors. Although radiographs are the gold standard for initial imaging evaluation and may make the diagnosis, computed tomography (CT) and magnetic resonance (MR) imaging are important ...

Clinicopathologic study of 6 cases of epithelioid osteoblastoma of the jaws with immunoexpression analysis of FOS and FOSB.

Oral surgery, oral medicine, oral pathology and oral radiology, 2020
OBJECTIVE The aim of this study was to describe the clinicopathologic features of a series of gnathic epithelioid osteoblastomas. As high levels of Proto-oncogene c-Fos proteins resulting from FOS-FOSB translocation were recently demonstrated in ...

Benign Osteoblastoma Involving Maxilla: A Case Report and Review of the Literature

Case Reports in Dentistry, 2012
Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible.

Aggressive osteoblastoma of the cervical spine and resultant complication due to swollen oxidized regenerated cellulose: A case report

Surgical neurology international
Background: Osteoblastomas, although rare, are benign primary bone tumors, with cervical spine involvement being exceptionally uncommon. Late diagnosis, especially in aggressive cases, can lead to surgical challenges. Oxidized regenerated cellulose (ORC)

FOS-ANKH and FOS-RUNX2 Fusion Genes in Osteoblastoma

Cancer Genomics & Proteomics, 2020
Background/Aim: Osteoblastoma is a rare benign tumor of the bones in which recurrent rearrangements of FOS have been found. Our aim was to investigate two osteoblastomas for possible genetic aberrations. Materials and Methods: Cytogenetic, RNA sequencing,

Utility of FOS as diagnostic marker for osteoid osteoma and osteoblastoma

Virchows Archiv, 2019
Osteoid osteoma and osteoblastoma are bone-forming tumors shown to harbor FOS (87%) and FOSB (3%) rearrangements. The aim was to evaluate the immunohistochemical expression of FOS and FOSB in these tumors in comparison to other bone tumors, to evaluate ...
