Chondroid Soft Tissue Tumors With FOS::PABPN1 Fusion: A New Entity? About Two Cases

Genes, Chromosomes and Cancer, Volume 65, Issue 8, August 2026.
ABSTRACT Soft tissue tumors with chondroid matrix represent a heterogeneous group with persistent diagnostic challenges. Advances in molecular diagnostics have identified recurrent gene fusions in several chondroid neoplasms, predominantly involving FN1. Here, we report two cases of chondroid tumors harboring a novel FOS::PABPN1 fusion.

Maxillofacial Cemento‐Ossifying Fibroma: A Rare Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Cemento‐ossifying fibroma is a relatively rare lesion affecting the jaws, especially the anterior mandible. The most common clinical presentation is swelling. Diagnosis based on clinical observation only is challenging. Radiological images and histological findings can be misleading due to similitudes with other osteo‐fibrous lesions.

Surgical Resection of Lumbar Spine Osteoblastoma With Secondary Aneurysmal Bone Cysts Through a Combined Transpsoas and Posterior Approach: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Aggressive lumbar osteoblastoma with secondary aneurysmal bone cysts is rare and may involve both posterior elements and vertebral bodies. When extensive multilevel involvement is present, a combined posterior and transpsoas approach can facilitate complete tumor resection, restore spinal stability, and achieve favorable neurological and ...

Consensus recommendations in the management of jaw (gnathic) osteosarcoma

Cancer, Volume 132, Issue 5, 1 March 2026.
Abstract Gnathic osteosarcoma (OS), which includes mandibular and maxillary jaw OSs, account for 6%–9% of OS. Single‐institutional and multi‐institutional retrospective studies, as well as population‐level databases, suggest that clinical differences exist among gnathic OS and OS of other sides, including other craniofacial OS.
