Though usually presenting as an atypical chronic myeloid leukemia, the present case is the fourth BCR-FGFR1-positive patient diagnosed with lymphoblastic leukemia (Table 1) suggesting that specific domains or amino acid residues of the translocation partner protein of FGFR1 may not be the dominant factor that influences the presenting phenotype [22]. This evidence concerns the gene BCR and chronic myelogenous leukemia, BCR-ABL1 positive.
