PG - 100320 LID - 10.1016/j.lrr.2022.100320 [doi] LID - 100320 AB - Acute promyelocytic leukemia (APL) is a unique leukemia that is characterized by the PML::RARA fusion. This fusion is often detected by conventional karyotype and fluorescence in situ hybridization (FISH); however, rare cases are cryptic and require molecular techniques to identify the PML::RARA fusion. Furthermore, as the incidence of these cases is rare, analysis by a targeted next-generation sequencing (NGS) panel of myeloid associated genes has never been reported. Herein, a clinical APL case is reported where the PML::RARA fusion was detected only by reverse transcriptase-polymerase chain reaction (RT-PCR), thus underscoring the necessity of utilizing complementary techniques when suspicion for APL is present.
