Upon further investigation, the child had immature myeloid series cells in the peripheral blood smear, which on Bone Marrow Aspiration (BMA), flow cytometry, and Fluorescent In Situ Hybridisation (FISH) confirmed a case of APML. A major manifestation of this chime...
Acute Promyelocytic LeukemiaPeripheral Blood SmearAcute Promyelocytic Leukemia PatientDerivative ChromosomeDear Sir, Acute promyelocytic leukemia (APL) is characterized by the translocation of chromosomal (15;17)(q22;q21) involving the fusion of the promyelocytic leukemia (PML) and RARA genes, resulting in...
Finding a myeloblast in a peripheral blood smear always raises the concern of granulocytic leukemia (although it must be kept in mind that it is difficult, if not impossible, to reliably distinguish myeloblasts from lymphoblasts on the basis of morphology alone). However, rarely, a myelob...
On day 2, flow cytometry of the peripheral smear showed 43% medium sized blasts. Fluorescence in situ hybridization was positive for promyelocytic leukemia/retinoic acid receptor alpha. Diagnoses: The patient was diagnosed with APL. Interventions: Patient was started on treatment with all-trans ...
Careful study of the peripheral blood smear may reveal blasts in such cases. Abnormal coagulation studies may be present. Figure 18.14 Acute promyelocytic leukemia (FAB M3), bone marrow clot. The marrow is replaced by a diffuse infiltrate of blasts with abundant, heavily granulated cytoplasm. APL...
Hypercalcemia associated with the interaction between all trans retinoic acid and posaconazole in an acute promyelocytic leukemia case: All-trans retinoic acid (ATRA) is a physiological metabolite of vitamin A and it is used for the treatment of acute promyelocytic leukemia (APL). Hypercalc... HBA...
Recently, hypocellular acute promyelocytic leukemia with a tetraploid clone has also been reported [10]. The question of pathogenesis of the hypocellularity remains speculative. It is unclear whether the leukemia is secondary to the hypocellularity or if it is the primary event. It has been ...

According to both guidelines, the finding of a translocation between chromosomes 15 and 17, or t(15;17), is associated with a diagnosis of acute promyelocytic leukemia (APL), an AML subtype that is treated and monitored differently than other subtypes. [28, 119] Treatment Both the NCCN and...
Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML), classified by a translocation between chromosomes 15 and 17 [t(15;17)], that is considered a true oncologic emergency though appropriate therapy is considered curative. Therapy is often initiated on clinical suspicion...
