    Detecting Rare ALK Gene Fusions in Unclassified Spindle Cell Lung Tumors Using Anchored Multiplex PCR/Targeted RNA Next-Generation Sequencing. (PubMed, Genes Chromosomes Cancer)
    Our results support the incorporation of ALK immunohistochemistry as a screening tool and demonstrate the utility of anchored multiplex PCR-based RNA sequencing for the detection of therapeutically relevant fusions, particularly those with uncommon partners. This integrated approach may refine the diagnosis and support consideration of ALK-directed therapy in these rare tumors.

    Clinicopathologic correlates of Ewing (FET::ETS-rearranged) sarcoma and non-Ewing undifferentiated small round cell sarcomas across skeletal and extraskeletal sites. (PubMed, Front Oncol)
    Within the Ewing group, skeletal versus extraskeletal presentation did not influence outcome, despite clear age differences. Integrating molecular diagnostics with site-specific and histopathologic assessment enhances diagnostic accuracy and guides management of these biologically diverse tumors.

    Epithelioid leiomyosarcoma harboring HMGA2::RAD51B fusion: expanding the spectrum of RAD51B-rearranged uterine sarcoma. (PubMed, Virchows Arch)
    The patient remains disease-free at 4 months. This case expands the molecular spectrum of ELMS and, concomitantly, broadens the emerging morphologic spectrum of RAD51B-rearranged uterine sarcomas, underscoring the diagnostic value of fusion testing in unusual uterine mesenchymal neoplasms.

    RNA-based multiplex polymerase chain reaction and sequencing to detect fusion genes in melanoma (ESMO Asia 2024)
    Conclusions The Archer® FUSIONPlex® custom panel detected fusion genes in 10% of driver gene-negative melanomas. Combining DNA- and RNA-based multiplex sequencing is useful to identify potentially targetable gene alterations.

    Myositis ossificans: rare paediatric case diagnosed with FNAB and confirmed by RNA genotyping of cytology sample (ECP 2024)
    When myositis ossificans presents with typical clinical history and a clear zonal pattern on imaging, diagnosis is relatively straightforward. However, in early lesions without typical clinical features the diagnosis may be more challenging and sometimes requires a biopsy. Our case shows that FNAB with supported by immunocytochemistry and RNA genotyping proving COL1A1::USP6 fusion allows accurate diagnosis in less than 6 days and implicates the potential use of molecular methods on FNAB samples of soft tissue lesions.

    Intraosseous spindle cell rhabdomyosarcoma with FET (EWSR1)- TFCP2 and LOC101929418-ALK fusions: a case report and literature review (ECP 2024)
    After unsuccessful chemotherapy, Alectinib (ALK inhibitor) combined with radiotherapy was initiated... Intraosseous spindle cell rhabdomyosarcoma (RMS) with TFCP2 rearrangement is a highly aggressive tumour with an early onset, fast progression and poor response to standard therapies. Our case, one of the few cases described with two gene fusions, contributes to understanding its molecular profile. Further clinical studies are required to explore the efficacy of targeted therapy for ALK and for the development of new effective treatment approaches.

    NTRK-rearranged spindle cell neoplasms – report of two cases with divergent morphology (ECP 2024)
    Identifying patients with NTRK gene fusions is crucial, as they could benefit from targeted therapy using TRK inhibitors. This requires a detailed description of emerging entities like NTRK-RSCNs because testing for NTRK rearrangement is not routinely performed. In two cases, we report a spectrum of histological grades, including a high-grade phenotype.

    Synovial sarcoms presenting atypical FISH positive pattern with loss of green signal. Molecular characteristics of 2 new cases and systematic review of the literature (ECP 2024)
    Atypical SS18-break apart FISH pattern with loss of green signal should be interpreted as a peculiar unbalanced rearrangement of the SS18 gene and subsequent SS18-SSX fusion (IHC or/and NGS) test should be recommended in such cases. Reseach are partially supported by grant of the The National Centre for Research and Development no. GOSPOSTRATEG-VI/0016/2021.

    A report of an exceptional case of rhabdomyosarcoma of the tongue harbouring THBS1::ALK fusion and literature review (ECP 2024)
    Rhabdomyosarcomas are a heterogenous group of malignant neoplasms rarely occurring in adults. Immunohistochemical ALK-positivity has been described in RMS, however underlying ALK rearrangements are rare events. This is the first case harboring THBS1::ALK fusion, which was previously described in inflammatory myofibroblastic tumours.

    CD34-positive spindle cell tumour with FGFR1::TACC1 fusion: entity of uncertain behaviour (ECP 2024)
    In this particular case, the immunohistochemical and molecular results support a diagnosis of a fibroblastic/myofibroblastic tumour of uncertain behaviour. Notably, there have been no reported cases in the literature of a soft tissue tumour harboring FGFR1::TACC1 fusion as a primary occurrence in this anatomical location. The patient remains in good health without any evidence of disease recurrence at the 5-month follow-up post-surgical intervention.

    Challenging presentations of synovial sarcomas: shedding light on the uncommon (ECP 2024)
    Our cases on atypical presentations of SS shows unusual morphological, immunophenotype, and molecular features. We consider it relevant to include SS as a differential diagnosis when faced with pseudo-vascular/alveolar patterns. Even in cases with more typical morphology of SS, there is a possibility of finding negative results in either IHC or FISH techniques due to cryptic or complex rearrangement.

    A fibroblastic reticular cell tumour as unexpected diagnosis (ECP 2024)
    Fibroblastic reticular cell tumour (FRCT) is a rare tumour with 21 cases reported in the literature. FRCTs are characterized by cells arranged in a whorls, fascicles or sheets accompanied by lymphoplasmacytic infiltrate. FRCT shows overlapping morphological features with follicular dendritic cell sarcoma (FDCS) and interdigitating dendritic cell sarcoma (IDCS).
