The fifth edition of the World Health Organization Classification of Tumors of Soft Tissue and Bone was published in early 2020. The revisions reflect a consensus among an international expert editorial board composed of soft tissue and bone pathologists, geneticists, a medical oncologist, surgeon, and radiologist. The changes in the soft tissue tumor chapter notably include diverse, recently described tumor types (eg, atypical spindle cell/pleomorphic lipomatous tumor, angiofibroma of soft… 
New molecular entities of soft tissue and bone tumors.
Purpose of review The advances of molecular techniques have led to the refinement of the classification of mesenchymal tumors, leading to newly introduced entities in the recently published fifth
From the ashes of "Ewing-like" sarcoma: A contemporary update of the classification, immunohistochemistry, and molecular genetics of round cell sarcomas.
This work reviews the diagnostic categories that have emerged from the former wastebasket "undifferentiated round cell sarcoma" ("Ewing-like" sarcomas), with an emphasis on algorithmic exclusion of nonsarcomatous entities and diagnostic stratification of well-defined entities.
‘I Can’t Keep Up!’: an update on advances in soft tissue pathology occurring after the publication of the 2020 World Health Organization classification of soft tissue and bone tumours
This review will attempt to summarise the developments in soft tissue pathology that have occurred since 2020, emphasising lesions for which morphology and genetics intersect in a complementary fashion.
Imaging and Pathological Features of Alveolar Soft Part Sarcoma: Analysis of 16 Patients
ASPS is a rare soft tissue sarcoma seen in children and young adults and imaging may mimic a vascular malformation due to the presence of tortuous feeders, thus emphasizing the need to suspect it on imaging.
Soft tissue masses: distribution of entities and rate of malignancy in small lesions
The rate of malignancies decreased significantly with tumor size in both, superficial and deep STMs, yet there was no significant difference found in the malignancy rate.
Prognostic Significance of Bone Metastasis in Soft Tissue Sarcoma Patients Receiving Palliative Systemic Therapy: An Explorative, Retrospective Pooled Analysis of the EORTC-Soft Tissue and Bone Sarcoma Group (STBSG) Database
Adult STS patients receiving palliative systemic therapy with bone metastasis carried an overall worse prognosis than STs patients without bone metastases, independent of the treatment line.
Soft tissue solitary fibrous tumors of the musculoskeletal system: spectrum of MRI appearances and characteristic imaging features
MSK-SFTs commonly present as well-defined, hypervascular masses deep to fascia along major neurovascular bundles, with heterogeneous slightly hyperintense T1 signal, intermediate-to-high T2/STIR signal, and prominent macroscopic flow voids.
RAF1-rearranged spindle cell tumour: report of two additional cases with identification of a novel FMR1-RAF1 fusion
The genetic spectrum of RAF1-rearranged spindle cell tumour is expanded by describing a novel FMR1-RAF1 fusion gene.


Solitary fibrous tumor: a clinicopathological study of 110 cases and proposed risk assessment model
Patients with resected primary solitary fibrous tumor were identified and the most common sites of occurrence were abdomen and pleura; these tumors were larger than those occurring in the extremities, head and neck or trunk, but did not demonstrate significant outcome differences.
Solitary fibrous tumor: a case series identifying pathological adverse factors—implications for risk stratification and classification
SFTs with adverse pathological parameters were not always related with a poor outcome, thus confirming the unpredictable clinical behavior of SFT, and the inclusion of molecular factors ( TP53 and TERT promoter status) may provide new prognostic indicators for future risk stratification systems, especially in the intermediate-risk group.
PRDM10-rearranged Soft Tissue Tumor: A Clinicopathologic Study of 9 Cases
Clinical features of this small series suggest an indolent behavior of PRDM10-rearranged soft tissue tumor, justifying its distinction from UPS and other sarcomas.
The histologic spectrum of soft tissue spindle cell tumors with NTRK3 gene rearrangements
An additional subset of seven tumors sharing NTRK3 gene rearrangements is described, which includes high‐grade fascicular monomorphic spindle cell sarcomas, morphologically somewhat reminiscent of either malignant peripheral nerve sheath tumors (MPNSTs) or fibrosarcomas (FSs).
The Current Status of Solitary Fibrous Tumor
It is recognized thatolitary fibrous tumor is a translocation-associated neoplasm, consistently associated with NAB2-STAT6 gene fusions arising from recurrent intrachromosomal rearrangements on chromosome 12q, and this translocation is a likely major contributor to its pathogenesis.
EWSR1-NFATC2 Translocation-associated Sarcoma Clinicopathologic Findings in a Rare Aggressive Primary Bone or Soft Tissue Tumor
Six sarcomas harboring EWSR1-NFATC2 fusion transcripts by reverse transcription polymerase chain reaction and amplification of the fusion gene by fluorescence in situ hybridization were identified and showed poor histologic and radiologic responses to neoadjuvant ES-specific chemotherapy.
Recurrent Pleomorphic Myxoid Liposarcoma in a Patient With Li-Fraumeni Syndrome
This is the first case of pleomorphic myxoid liposarcoma diagnosed in an adult with Li-Fraumeni syndrome and it is reported that the tumor progressed with multiple recurrences and metastasis to the humerus bone.
Sarcomas With CIC-rearrangements Are a Distinct Pathologic Entity With Aggressive Outcome: A Clinicopathologic and Molecular Study of 115 Cases
The findings show that CIC-DUX4 sarcomas occur most commonly in young adults within the somatic soft tissues, having a wide spectrum of morphology including round, epithelioid and spindle cells, and associated with an aggressive clinical course, with an inferior overall survival compared with Ewing sarcoma.
Limited biopsies of soft tissue tumors: the contemporary role of immunohistochemistry and molecular diagnostics
Examples of recently developed markers for the diagnosis of selected soft tissue tumor types will be discussed, including solitary fibrous tumor (STAT6), malignant peripheral nerve sheath tumor (H3K27me3), epithelioid hemangioendothelioma (CAMTA1), dedifferentiated liposarcoma (MDM2), and CIC-DUX4 sarcomas (WT1 and ETV4).
