Acute Myelocytic Leukemia - Microscopic View

This microscope image shows AML cells (acute myeloblastic leukemia; also referred to as ANLL, acute nonlymphocytic leukemia). Certain internal cell structures are typical of AML. These include prominent nucleoli (red arrows) and cytoplasmic granules (grainy structures inside the cell which indicate some degree of cell maturation--black arrow).

Acute Myelomonocytic Leukemia - Microscopic View

This microscope image shows immature cells containing prominent nucleoli. The nuclei are large, lobulated, and/or irregular, resembling the nuclei of monocytes.

Auer Rods

Note multiple Auer rods which are found only in acute myeloid leukemias, either myeloblastic or monoblastic. These rods consist of clumps of azurophilic granule material.

Acute Monocytic Leukemia - Skin

Acute monocytic leukemia. These lesions are rarely found in chronic leukemia but are a common finding in acute forms. They appear as erythematous infiltrations of the skin, forming papules, macules, and plaques. Pruritus may be present.

Blood Cells

Blood is comprised of red blood cells, platelets, and various white blood cells.
