Preoperative embolization of hypervascular spinal tumors: Two case reports.

J Clin Imaging Sci 2022 2;12:21. Epub 2022 May 2.

Department of Radiology, Pham Ngoc Thach University of Medicine, Ho Chi Minh City, Vietnam.

We discuss two cases of hypervascular spinal tumors that were successfully treated with preoperative embolization and surgery. The first patient was an 18-year-old man who presented with cervical and shoulder pain for two months without paralysis or weakness. Read More

[Giant cell-containing tumors of bone and differential diagnoses].

Pathologe 2022 May 25;43(3):174-182. Epub 2022 Apr 25.

Gerhard-Domagk-Institut für Pathologie, Universitätsklinikum Münster, Albert-Schweitzer-Campus 1, 48149, Münster, Deutschland.

Osteoclastic giant cells represent a common cellular component of lesions arising in bone. Highlighting this morphological finding, the current WHO classification of bone tumors defines a diagnostic group comprising aneurysmal bone cyst, giant cell tumor of bone and non-ossifying fibroma, which may display morphologic similarities while being distinct with regard to molecular and biological features. Starting with these tumors - putting a focus on lesions arising in bone - this article gives a survey of other (chondrogenic and osteogenic) tumors that frequently contain osteoclastic giant cells, which may, particularly in small biopsies, enter differential diagnosis.

Methylation and copy number profiling: emerging tools to differentiate osteoblastoma from malignant mimics?

Mod Pathol 2022 Mar 28. Epub 2022 Mar 28.

Bone Tumor Reference Center at the Institute for Medical Genetics and Pathology, University Hospital Basel, University of Basel, Basel, Switzerland.

Rearrangements of the transcription factors FOS and FOSB have recently been identified as the genetic driver event underlying osteoid osteoma and osteoblastoma. Nuclear overexpression of FOS and FOSB have since then emerged as a reliable surrogate marker despite limitations in specificity and sensitivity. Indeed, osteosarcoma can infrequently show nuclear FOS expression and a small fraction of osteoblastomas seem to arise independent of FOS/FOSB rearrangements. Read More

Aneurysmal bone cyst and osteoblastoma after neoadjuvant denosumab: histologic spectrum and potential diagnostic pitfalls.

APMIS 2022 Apr 18;130(4):206-214. Epub 2022 Feb 18.

Department of Pathology, Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA.

The use of denosumab to treat giant cell tumors of bone (GCT) and other giant cell-containing bone tumors has become more common. While the clinicopathologic features of denosumab-treated giant cell tumors of bone have been well-illustrated, descriptions of other denosumab-treated bone tumors are very limited. Surgical pathology files of two institutions and consultation files from two authors were searched for denosumab-treated aneurysmal bone cysts and denosumab-treated osteoblastomas. Read More

Weakening or Structural Strengthening? An Evaluation of Bone Density after MRgFUS Ablation for Treatment of Benign Bone Lesions.

J Clin Med 2021 Dec 29;11(1). Epub 2021 Dec 29.

Department of Emergency and Interventional Radiology, San Salvatore Hospital, 67100 L'Aquila, Italy.

Previous studies suggest that interventional ablative procedures on bone lesions may weaken the bone, especially when performed through the needle approach. Our purpose was to evaluate, through Computed Tomography (CT), the effects of Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) ablation on painful osteoid osteomas and osteoblastomas in terms of bone density and morphological changes. We retrospectively evaluated patients treated at our institution with MRgFUS for superficial, painful osteoid osteoma or osteoblastoma during the last 9 years. Read More
