Is purpura a precursor to leukemia?

Purpura is not necessarily a precursor to leukemia.

Purpura is a symptom of bleeding from the skin, usually manifested as red or purple spots, plaques, or ecchymoses on the skin. There are many causes of purpura, including thrombocytopenia, abnormal blood vessel walls, anaphylaxis, infection, etc. Leukemia is a hematological malignancy characterized by abnormal proliferation and infiltration of white blood cells, leading to anemia, bleeding, infection, etc.

Although leukemia may cause thrombocytopenia, which causes purpura, this is not the cause of all purpura. Other diseases, such as thrombocytopenia purpura, anaphylactoid purpura, etc., may also cause purpura.

To determine whether purpura is related to leukemia, a series of tests, such as blood tests, bone marrow tests, etc., are needed. If the test results show signs of leukemia, the doctor will further evaluate and diagnose.
