Secondary plasma cell leukaemia (PCL) with plasmablastic morphology.
Ke XuElisabeth NachevaPublished in: Journal of hematopathology (2024)
A 71-year-old female with relapsed IgA lambda myeloma developed progressive cytopenia. The peripheral blood film showed 5% blastoid cells. Flow cytometry analysis was indicative of plasma cells. The bone marrow smear was packed with plasmablasts. Target CD138-cell FISH and molecular karyotyping identified a complex genome. NGS identified high-risk mutations. Bone marrow histology confirmed myeloma with no evidence of acute leukaemia. The patient was diagnosed with plasmablastic progression of myeloma and secondary PCL. Secondary PCL patients have a poor prognosis. It is essential to recognize this subtype and explore a novel treatment approach.
