Giant cell tumour (GCT) of the spine is a benign aggressive tumour with high recurrence rates. Patients can be asymptomatic due to the slow growth rate and present with localized pain or neurological dysfunction. Current management strategies include intralesional curettage, total en-bloc resection (TER) and denosumab therapy. Treatment strategies can be particularly challenging in women of childbearing age who wish to conceive, as the risks of tumour recurrence need to be balanced against the fetal complications associated with adjuvant denosumab therapy. This case report discusses the management options and controversies for women of childbearing age with GCT of the thoracic spine. Clinicians need to be aware of the complications associated with TER and denosumab treatment when managing GCTs of the spine in young females.

Increasing evidence suggests that active matter exhibits instances of mixed symmetry that cannot be fully described by either polar or nematic formalism. Here, we introduce a minimal model that integrates self-propulsion into the active nematic framework. Our linear stability analyses reveal how self-propulsion shifts the onset of instability, fundamentally altering the dynamical landscape.

Background: Dermal clear cell sarcoma (DCCS) is a rare malignant mesenchymal neoplasm. Owing to the overlaps in its morphological and immunophenotypic profiles with a broad spectrum of tumors exhibiting melanocytic differentiation, it is frequently misdiagnosed as other tumor entities in clinical practice. By systematically analyzing the clinicopathological characteristics, immunophenotypic features, and molecular biological properties of DCCS, this study intends to further enhance pathologists' understanding of this disease and provide a valuable reference for its accurate diagnosis.

Understanding how cells control their biophysical properties during development remains a fundamental challenge. While macromolecular crowding affects multiple cellular processes in single cells, its regulation in living animals remains poorly understood. Using genetically encoded multimeric nanoparticles for in vivo rheology, we found that tissues maintain mesoscale properties that differ from those observed across diverse systems, including bacteria, yeast species, and cultured mammalian cells.

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Aims: Sarcoid myopathy (SaM) is characterised by granulomatous myositis (GM) and can overlap with inclusion body myositis (IBM), a late-onset chronic idiopathic inflammatory myopathy with a still enigmatic pathogenesis. As GM can occur in different clinical contexts, we aimed to examine the histomorphologic features and gene expression profiles in cases of definite SaM that may inform diagnostic and therapeutic considerations.
Methods: We performed a multidimensional characterisation of muscle biopsy specimens from patients with 'pure SaM' (n=17), SaM with concomitant IBM (SaM-IBM) (n=2), including histopathologic and ultrastructural analysis in addition to quantitative real-time polymerase chain reaction.
