The presence of BCR\u2013ABL1 further complicates classification and management, as it carries important prognostic and therapeutic implications. We report a case of BCR\u2013ABL1\u2013positive MPAL diagnosed through integrated morphological, immunophenotypic, and cytogenetic evaluation. The case highlights key diagnostic pitfalls and underscores the importance of comprehensive immunophenotyping and molecular testing to avoid misclassification as acute myeloid leukemia or acute lymphoblastic leukemia. Recognition of this entity is critical for appropriate therapeutic decision\u2010making, including the use of tyrosine kinase inhibitors. This report emphasizes the need for heightened awareness of MPAL with BCR\u2013ABL1, representing a form of high\u2010risk acute leukemia with significant therapeutic implications, particularly in resource\u2010limited settings where diagnostic constraints may delay optimal management.<\/jats:p>","DOI":"10.1155\/crh\/2170200","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T05:54:43Z","timestamp":1790142883000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Diagnostic
