What is M3 Leukemia?
M3 refers to Acute Promyelocytic Leukemia (APL), a distinct subtype of Acute Myeloid Leukemia (AML) classified under the FAB system.
It is characterized by the accumulation of abnormal promyelocytes in the bone marrow and blood, often containing multiple Auer rods. This subtype is clinically significant due to its association with severe bleeding disorders.
Key Features of M3 (APL)
- Presence of abnormal promyelocytes
- Multiple Auer rods in cells

M3 leukemia is considered a medical emergency due to its bleeding risk. However, it is also one of the most treatable forms of AML when diagnosed early.
Targeted therapies such as ATRA and arsenic trioxide have significantly improved survival rates in patients with M3 (APL).
