Background: The aim of the study was to improve the clinical cognition of nonaccelerating myelodysplastic/myeloproliferative neoplasms-unclassifiable (MDS/MPN-U) with 5q- karyotype and to avoid misdiagnosis or delayed diagnosis.
Methods: The clinical manifestations and laboratory results of a patient with nonaccelerating MDS/MPN-U with 5q- karyotype were analyzed, and related literature was reviewed.
Results: The patient was admitted to hospital mainly due to chest tightness and shortness of breath, aggravated for 4 days. After admission, combined with clinical manifestations, bone marrow cell morphology, immunology, multiparameter flow cytometry, cytogenetics and molecular biology, etc., the final diagnosis was MDS-MPN-U. Conclusions: Research on the correlation between MPN-U and MDS with 5q deletion is still needed. Clinically, MPN-U combined with MDS is prone to misdiagnosis. In diagnosing MPN-U patients, it is essential to not only complete routine and immunological tests but also consider clinical manifestations and laboratory results. It is crucial to be vigilant about the possibility of concurrent diseases, especially cancer, and to choose targeted examinations in a timely manner to avoid missed or incorrect diagnoses.
