Recognised as a distinct entity within acute myeloid leukaemia (AML), MS presents significant diagnostic challenges due to its rarity, clinical heterogeneity, and variable immunophenotypic and genetic characteristics. The mechanisms by which leukaemic stem cells (LSCs) migrate to form solid tumours in extramedullary (EM) sites remain unclear. MS can occur de novo, precede AML, and manifest alongside AML relapse. It can also develop with myelodysplastic syndromes (MDSs) or myeloproliferative neoplasms (MPNs). MS frequently presents in organs such as the skin, lymph nodes, gastrointestinal (GI) tract, and central nervous system (CNS), often resulting in diverse clinical manifestations. Diagnosis relies on a comprehensive approach, including tissue biopsy, bone marrow (BM) evaluation, and advanced imaging modalities. Accurate diagnosis is crucial for risk stratification and treatment selection. Prognosis is influenced by several factors: MS\u2019s anatomical location, timing of MS diagnosis, genetic profile, and possible treatment. This review emphasises the need for comprehensive diagnostic methods to better define individual MS characteristics and prognosis. It explores the role of novel targeted therapies in improving patient outcomes and further highlights the critical need for future multicentre data collection to optimise diagnostic and therapeutic approaches.<\/jats:p>","DOI":"10.3390\/cimb47020111","type":"journal-article","created":{"date-parts":[[2025,2,10]],"date-time":"2025-02-10T03:39:47Z","timestamp":1739158787000},"page":"111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Diagnostic Approaches in Myeloid Sarcoma"],"prefix":"10.3390","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8691-4310","authenticated-orcid":false,"given":"Elzbieta","family":"Patkowska","sequence":"first","affiliation":[{"name":"Department of Haematopoietic Stem Cell Transplantation, Institute of Hematology and Transfusion Medicine, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7647-3336","authenticated-orcid":false,"given":"Agnieszka","family":"Krzywdzinska","sequence":"additional","affiliation":[{"name":"Immunophenotyping Laboratory, Department of Hematological Diagnostics, Institute of Hematology and Transfusion Medicine, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iwona","family":"Solarska","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory, Department of Hematological Diagnostics, Institute of Hematology and Transfusion Medicine, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Wojtas","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory, Department of Hematological Diagnostics, Institute of Hematology and Transfusion Medicine, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Prochorec-Sobieszek","sequence":"additional","affiliation":[{"name":"Pathomorphology Laboratory, Department of Hematological Diagnostics, Institute of Hematology and Transfusion Medicine, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,10]]},"reference":[{"key":"ref_1","unstructured":"Swerdlow, S.H., Campo, E., Harris, N.L., Jaffe, E.S., Pileri, S.A., Stein, H., Thiele, J., and Vardiman, J.
