Abstract:

Introduction: Myeloproliferative neoplasms (MPNs) are divided into BCR-ABL positive Chronic myeloid leukemia (CML) and BCR-ABL negative MPNs including Polycythemia vera (PV), Essential Thrombocythemia (ET) and Primary myelofibrosis (PMF). Evaluation of the Philadelphia chromosome in MPNs is a diagnostic requirement for classic CML.

Case Report: In 2020, a 37-year-old woman with negative cytogenetic testing for Janus kinase2 (JAK2), Calreticulin (CALR), myeloproliferative leukemia virus oncogene (MPL), and positive for BCR-ABL1 mutation with reticular fibrosis in bone marrow was diagnosed as CML. Some years ago, the patient had been diagnosed with PMF with evidence of histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease (KFD). The BCR-ABL fusion gene was initially evaluated which was negative. Then, Cutaneous squamous cell carcinoma (cSCC) was confirmed by Dermatopathologist with palpable splenomegaly and high white blood cell (WBC) count with basophilia. Finally, BCR-ABL was detected positive by the fluorescence in situ hybridization (FISH) and quantitative real-time polymerase chain reaction (qRT-PCR). In fact, the co-occurrence of PMF with CML was identified.

Conclusion: This case study highlighted the importance of some cytogenetic methods in the detection and classification of MPNs. It is recommended that physicians pay more attention to it and be aware of the planning treatment.
