Abstract:
Evaluation of cell morphology is usually sufficient to diagnose acute promyelocytic leukaemia (APL). In this chapter we discuss the features of classical hypergranular APL, the APL variant, hyperbasophilic promyelocytic leukaemia, APL with basophil-like granules, acute eosinophilic leukaemia with PML/RARalpha positivity and the morphology of APL cells lacking t(15;17). In addition to morphological examination, cytochemical investigations (peroxidase chloroacetate-esterase, etc.) may help further in defining the cytology of leukaemic cells in APL.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
