Summary
Acute leukemias of ambiguous lineage (ALALs) are leukemias that show no clear evidence of differentiation along a single lineage [1]. ALALs are rare and comprise 2–3% of acute leukemia (0.35 cases per 1 million person-years) [1–5]. They occur in both children and adults, with a male predominance [1,2,4].
ALALs represent a heterogeneous group of diseases. Cases of ALAL mostly fall into two broad categories: acute undifferentiated leukemia (AUL) and mixed-phenotype acute leukemia (MPAL) [1–5]. The current classification is mainly based on immunophenotypes and genetic features outlined in World Health Organization (WHO) classification system (Table 17.1) [1,2,5,6].
