An acute myeloid leukemia (AML) rash may appear in the form of small spots or bruises. However, if the rash develops because leukemia cells have spread to the skin, it may look like other types of rash and cover an extensive part of the body.
On light skin, this type of rash often appears as red or purple. On dark skin, it may look darker and be less noticeable.
Keep reading to learn about rashes, bruises, red spots, and other symptoms of AML, as well as when to contact a doctor.
Leukemia cells of AML may spread from the blood and bone marrow to the skin. When this occurs, it causes lumps and spots that look like ordinary rashes.
Leukemia cutis appears as red or purplish red, and it occasionally looks dark red or brown. It affects the outer skin layer, the inner skin layer, and the layer of tissue beneath the skin.
The rash can involve flushed skin, plaques, and scaly lesions. It
Rashes on dark skin may look different from those on light skin. For example, they may not be as noticeable. Also, rather than appearing as red, they may look dark or purple.
The low platelet count in people with AML can mean that their bodies do not clot these breakages properly, and the red spots become noticeable.
Platelets usually help stop bleeding, including under the skin. Having fewer platelets can mean that bruises appear more easily or show up more clearly.
Sometimes, the red or purple spots that occur due to a low platelet count can look like bruises too.
A person with AML may also notice that their gums become swollen. In fact, according to one
People with AML may notice that they have firm, swollen gums that are more flushed than usual.
A person with AML may notice that they bleed more than usual.
For example, they may experience the following types of excessive bleeding due to having a low platelet count:
- Nosebleeds: A person with AML may notice that they are having chronic or severe nosebleeds.
- Menstrual periods: A person with AML may experience that their periods are longer or heavier than usual.
- Bleeding gums: A person with AML may notice that their gums are bleeding more than usual. This is due to inflammation in the mouth.
Acute promyelocytic leukemia
APL is an aggressive form of cancer in which too many cells that form blood, called promyelocytes, are present in the bone marrow and blood. This causes a decrease in red blood cells, white blood cells, and platelets.
A person with APL
Some other bleeding-related symptoms of APL include swelling from a blood clot called deep vein thrombosis, which usually occurs in the thigh or calf, and pulmonary embolism, which refers to the blockage of an artery in the lungs due to a blood clot.
Other AML symptoms can fall into different categories.
The symptoms may be general in nature, or they may stem from low blood cell counts, high numbers of leukemia cells, or the spread of leukemia cells.
Some general symptoms of AML are symptoms of other conditions as well. They are usually due to conditions other than leukemia.
Symptoms from low numbers of blood cells
When AML causes a reduction in red blood cells,
Sometimes, AML also causes a decrease in white blood cells, which usually fight infections. This can cause fevers and infections that last a long time.
Symptoms from high numbers of leukemia cells
Because leukemia cells of AML are larger than white blood cells, they have difficulty passing through tiny blood vessels.
When the cells increase in number, they can clog blood vessels, which makes it hard for tissues in the body to get enough oxygen from red blood cells. This rare medical emergency is called leukostasis.
Leukemia cells of AML can also produce symptoms if they accumulate in other areas.
Symptoms from the spread of leukemia cells
Certain symptoms stem from the spread of leukemia cells from the blood and bone marrow to other parts of the body, such as the aforementioned spread to the skin.
If the cells spread to the gums, they can cause pain, swelling, and bleeding in that area. The cells may also spread to the lymph nodes, which makes them larger.
If leukemia cells spread to the brain, it
The early symptoms of AML
A person who has any of the following symptoms should contact a doctor:
- shortness of breath
- easy bruising or bleeding
- unexplained weight loss
- loss of appetite
- fatigue or weakness
Treating AML early is important for improving quality of life and outlook.
An AML rash is one of a broad array of symptoms that a person with this condition may experience. The symptoms depend on which type of blood cells have reduced numbers and where in the body the cancer has spread.
If someone has any of the early symptoms of AML, they should contact a doctor as soon as possible.
