Which type of leukemia can be identified through cytochemical stains?

Acute leukemia is the correct choice because it encompasses both acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML), which can both be specifically distinguished using cytochemical stains. These stains help visualize certain cellular components that are characteristic of different types of leukemia. For instance, cytochemical stains can identify the presence of specific enzymes or cellular markers that are unique to acute leukemias.

Acute leukemia typically shows a rapid proliferation of immature blood cells, and the use of these stains assists in subclassifying the leukemias, determining lineage, and guiding treatment options. Staining can reveal features like the presence of myeloperoxidase in myeloid leukemias, or specific antigens in lymphoid leukemias, making it a valuable tool in diagnosis and management.

In contrast, chronic myeloid leukemia presents a more differentiated cell population and does not rely as heavily on cytochemical stains for identification. It is typically diagnosed through other methods such as genetic testing for the Philadelphia chromosome rather than through cytochemical techniques. Thus, acute leukemia is specifically noted for its utility in cytochemical identification.
