While the presence of a c-MYC rearrangement in this case favoured a PBL, these recurrent abnormalities are reported in myeloma as discussed by Affer et al. [5] and the demonstration of neoplastic plasma cells with a “typical” myeloma phenotype by flow cytometry in the bone marrow was more consistent with a blastic plasma cell myeloma. The gene discussed is MYC; the disease is plasma cell myeloma.
